Home Sweet Solar Home – Making Homes Better With Solar Technology

Executive Summary about Solar Home by Anne Clarke

By now many people know it is possible to generate energy without the use of dwindling traditional resources. This stimulated atmospheric cycle is the product of a solar biosphere that remains in constant, gradual motion. You can draw energy directly from the sunlight, you can save money on energy costs, and you can be a big part of the effort to protect our planet. Remember, though, solar panels are not the only type of solar technology available that can harvest a decent alternative to electricity from the sun. There are wind turbines, solar panels, biospheres, and many other innovative solar power mechanisms that have made headway in an extreme scientific objective to help protect the earth. Despite what many people might believe, there are solar solutions available as alternative energy sources that virtually anyone can choose over electrical energy. Soon construction companies for homes, office buildings, apartment complexes, and more will adopt new methods of design that will dovetail more easily with solar technology.

Solar Applications

June 21, 2011 By: Admin Category: Solar Power

Solar Energy Applications

Solar energy technologies use energy from the sun to produce heat, light, hot water, electricity, and even cooling, for homes, commercial and industrial.

There are a variety of technological applications that have been developed to take advantage of solar energy. Technology can be read further below.

Photovoltaics System

Solar cells work by converting sunlight directly into electricity. The electrons in the semiconductor material, the material used to capture sunlight, will move when the sun’s energy in the form of photons hit it. Solar energy is forcing the electrons to move, occur continuously, and consequently there is also a continuous electricity production. Process, which turns sunlight (photons) into electricity (voltage), called the photovoltaic effect.

Solar Cell Module

Solar cells are usually organized into modules that each module can consist of 40 solar cells. Some modules can be arranged to form a PV line fitted with a fixed angle facing south. Or even could be placed in a sun-tracking device, to get more solar energy throughout the day. Several rows of PV could produce enough power for a house. As for industrial applications or power companies, hundreds of lines of PV can be linked to form one large PV systems and sufficient to meet the electricity needs.

Thin Film Solar Cell

Thin film solar cells use several layers of semiconductor material with a thickness in the micrometer scale. Technology allows to create solar cells integrated into rooftops to the skylights. Even solar cells are designed for applications having the same power with actual roof.

Glitter-sized Solar Photovoltaics Produce Competitive Results

Adventures in microsolar supported by microelectronics and MEMS techniques

photovoltaic cells micro Photovoltaic Cells

Representative thin crystalline-silicon photovoltaic cells – these are from 14 to 20 micrometers thick and 0.25 to 1 millimeter across.

Sandia National Laboratories scientists have developed tiny glitter-sized photovoltaic cells that could revolutionize the way solar energy is collected and used.

The tiny cells could turn a person into a walking solar battery charger if they were fastened to flexible substrates molded around unusual shapes, such as clothing.

The solar particles, fabricated of crystalline silicon, hold the potential for a variety of new applications. They are expected eventually to be less expensive and have greater efficiencies than current photovoltaic collectors that are pieced together with 6-inch- square solar wafers.

The cells are fabricated using microelectronic and microelectromechanical systems (MEMS) techniques common to today’s electronic foundries.

Sandia lead investigator Greg Nielson said the research team has identified more than 20 benefits of scale for its microphotovoltaic cells. These include new applications, improved performance, potential for reduced costs and higher efficiencies.

“Eventually units could be mass-produced and wrapped around unusual shapes for building-integrated solar, tents and maybe even clothing,” he said. This would make it possible for hunters, hikers or military personnel in the field to recharge batteries for phones, cameras and other electronic devices as they walk or rest.

cells photovoltaic nielson Photovoltaic Cells

Sandia project lead Greg Nielson holds a solar cell test prototype with a microscale lens array fastened above it. Together, the cell and lens help create a concentrated photovoltaic unit.

Even better, such microengineered panels could have circuits imprinted that would help perform other functions customarily left to large-scale construction with its attendant need for field construction design and permits.

Said Sandia field engineer Vipin Gupta, “Photovoltaic modules made from these microsized cells for the rooftops of homes and warehouses could have intelligent controls, inverters and even storage built in at the chip level. Such an integrated module could greatly simplify the cumbersome design, bid, permit and grid integration process that our solar technical assistance teams see in the field all the time.”

For large-scale power generation, said Sandia researcher Murat Okandan, “One of the biggest scale benefits is a significant reduction in manufacturing and installation costs compared with current PV techniques.”

Part of the potential cost reduction comes about because microcells require relatively little material to form well-controlled and highly efficient devices.

From 14 to 20 micrometers thick (a human hair is approximately 70 micrometers thick), they are 10 times thinner than conventional 6-inch-by-6-inch brick-sized cells, yet perform at about the same efficiency.

100 times less silicon generates same amount of electricity

“So they use 100 times less silicon to generate the same amount of electricity,” said Okandan. “Since they are much smaller and have fewer mechanical deformations for a given environment than the conventional cells, they may also be more reliable over the long term.”

Another manufacturing convenience is that the cells, because they are only hundreds of micrometers in diameter, can be fabricated from commercial wafers of any size, including today’s 300-millimeter (12-inch) diameter wafers and future 450-millimeter (18-inch) wafers. Further, if one cell proves defective in manufacture, the rest still can be harvested, while if a brick-sized unit goes bad, the entire wafer may be unusable. Also, brick-sized units fabricated larger than the conventional 6-inch-by-6-inch cross section to take advantage of larger wafer size would require thicker power lines to harvest the increased power, creating more cost and possibly shading the wafer. That problem does not exist with the small-cell approach and its individualized wiring.

photovoltaic cell group1 Photovoltaic Cells

From left to right, Sandia researchers Murat OKandan, Greg Nielson, and Jose Luis Cruz-Campa, hold samples containing arrays of microsolar cells.

Other unique features are available because the cells are so small. “The shade tolerance of our units to overhead obstructions is better than conventional PV panels,” said Nielson, “because portions of our units not in shade will keep sending out electricity where a partially shaded conventional panel may turn off entirely.”

Because flexible substrates can be easily fabricated, high-efficiency PV for ubiquitous solar power becomes more feasible, said Okandan.

A commercial move to microscale PV cells would be a dramatic change from conventional silicon PV modules composed of arrays of 6-inch-by-6-inch wafers. However, by bringing in techniques normally used in MEMS, electronics and the light-emitting diode (LED) industries (for additional work involving gallium arsenide instead of silicon), the change to small cells should be relatively straightforward, Gupta said.

Each cell is formed on silicon wafers, etched and then released inexpensively in hexagonal shapes, with electrical contacts prefabricated on each piece, by borrowing techniques from integrated circuits and MEMS.

Offering a run for their money to conventional large wafers of crystalline silicon, electricity presently can be harvested from the Sandia-created cells with 14.9 percent efficiency. Off-the-shelf commercial modules range from 13 to 20 percent efficient.

A widely used commercial tool called a pick-and-place machine — the current standard for the mass assembly of electronics — can place up to 130,000 pieces of glitter per hour at electrical contact points preestablished on the substrate; the placement takes place at cooler temperatures. The cost is approximately one-tenth of a cent per piece with the number of cells per module determined by the level of optical concentration and the size of the die, likely to be in the 10,000 to 50,000 cell per square meter range. An alternate technology, still at the lab-bench stage, involves self-assembly of the parts at even lower costs.

Solar concentrators — low-cost, prefabricated, optically efficient microlens arrays — can be placed directly over each glitter-sized cell to increase the number of photons arriving to be converted via the photovoltaic effect into electrons. The small cell size means that cheaper and more efficient short focal length microlens arrays can be fabricated for this purpose.

High-voltage output is possible directly from the modules because of the large number of cells in the array. This should reduce costs associated with wiring, due to reduced resistive losses at higher voltages.

Other possible applications for the technology include satellites and remote sensing.

The project combines expertise from Sandia’s Microsystems Center; Photovoltaics and Grid Integration Group; the Materials, Devices, and Energy Technologies Group; and the National Renewable Energy Lab’s Concentrating Photovoltaics Group.

Involved in the process, in addition to Nielson, Okandan and Gupta, are Jose Luis Cruz-Campa, Paul Resnick, Tammy Pluym, Peggy Clews, Carlos Sanchez, Bill Sweatt, Tony Lentine, Anton Filatov, Mike Sinclair, Mark Overberg, Jeff Nelson, Jennifer Granata, Craig Carmignani, Rick Kemp, Connie Stewart, Jonathan Wierer,

George Wang, Jerry Simmons, Jason Strauch, Judith Lavin and Mark Wanlass (NREL).

The work is supported by DOE’s Solar Energy Technology Program and Sandia’s Laboratory Directed Research & Development program, and has been presented at four technical conferences this year.

The ability of light to produce electrons, and thus electricity, has been known for more than a hundred years.

What Is So Fascinating About Solar Pump

solar water pump Solar Pump

Solar-powered water pumps are an effective alternative to conventional gas or electric pumps. Modern pumps are powered by solar energy effectively in the world, including India, where they are often used for irrigation and drinking water.

The main advantage of solar pumps is that they work for free. A solar array connected to the pumping mechanism gains all the required power from simple sunshine. This also means that the system independently. There is no need for complicated wiring for the electricity and outside fuel is not needed.

The amount of pollution caused by the use of conventional pump has also completely eliminated. This is a big advantage, especially when used for irrigation on the farms where pollution can possible on site damage. Keeping the fossil fuels from the equation for the pumping of water will reduce potential contamination. In addition, the use of solar energy offers many benefits for agriculture, the farmers, for example, a solar pump used in an area of low-lying, which often flooded or to move the water used to feed animals and plants.

For any system of water pump, both large and small, the installation of solar systems is one of the easiest and most profitable. No long procedures for determining the wiring of the solar panels, and there is no need for extra fuel. Many of these systems, also the digital monitoring and control instruments adding for convenience.

Worldwide, the solar energy is one of the best ways of powering pump instrument. Simple installation, low maintenance, and reducing pollution are just some of the many benefits.

What Does Solar Cell Mean?

You may have seen a calculator that has a solar cell? calculator that does not need batteries, and in some cases do not even have the off button. As long as you have enough light, so the calculator can be on at any time and forever. You may have seen larger solar panels, such as in housing or traffic lights, haven’t you? In this article I will review how solar cell work so it can deliver the energy and drive an electronic device.

Today the demand for electricity has become a major requirement in all corners. The presence of power plants sometimes do not solve the need for electricity especially in remote areas where the terrain is always an excuse. Here an alternative energy that can be easily found in nature and can be used as an alternative free energy replacing conventional electricity, because it can turn on household electronics such as televisions, radios and lights.
solar cell p n Solar Cell
Solar cells made from pieces of a very small silicon coated with special chemicals to form the basis of solar cells. Solar cells generally have a minimum thickness of 0.3 mm is made from semiconductor materials incision with positive and negative poles. Each solar cell produces usually voltage 0.5 volts. Solar cells is an active element (semiconductor) that utilizes photovoltaic effect to transform solar energy into electrical energy.

solar cell diagram Solar Cell

Solar cells contain a connection (junction) between two thin layers made of semiconductor materials, each of which is known as a semiconductor type “P” (positive) and semiconductor type “N” (negative).

N-type semiconductor made of silicon crystals and there are also some other materials (typically phosphorus) within the limits that these materials can provide an excess of free electrons.

Electrons are sub atomic particles are negatively charged, so that the silicon alloy in this case known as N-type semiconductor (Negative). P-type semiconductor made of silicon crystal in which there is a small amount of other material (typically boron) which caused the shortage of material free electrons. Lack or loss of electrons is called a hole. Because there is no or lack of electrons electrically negative charged then the silicon alloys in this case as a semiconductor type-P (Positive).

Composition of a solar cell, the same as a diode, consisting of two layers, called PN junction. PN junction obtained by staining a pure semiconductor silicon (valence 4) with the impurity valence 3 on the left side, and one on the right impurity stained with valence 5.

The effect of the electric field in a PV cell

Solar Cell

Operation of a PV cell

Basic structure of a generic silicon PV cell

Thus formed on the left side that is not pure silicon again and called P type silicon, while the right side is called silicon type N. In the pure silicon there are two kinds of electrical charge carriers are balanced. Positive electric charge carriers called holes, while the negative are called electrons. After a desecration process, in the P type silicon formed holes (positive charge carriers) in a very large number compared with the electron. Therefore, in the P type silicon holes are majority charge carriers, while the electrons are minority carriers. Conversely, in the N type silicon is formed of electrons in a very large number so-called majority carriers, and holes called minority carriers.

In the silicon rod there was interaction between the P and the N. Therefore called the PN junction. When present, the P associated with the positive pole of a battery, while the negative polar associated with the N, then there is a relationship called “forward bias”.

Under forward bias, electrical currents arise in a series due to both types of charge carriers. So the electric current flowing in the PN junction is caused by the movement of electron and the movement of holes. An electric current is flowing in the direction of holes movement, but opposite direction with the movement of electrons. Just to further explain, electrons moving in the conductor material can lead to electrical energy. And electrical energy is called as an electric current that flows in the opposite direction to the movement of electrons.

But, if the P associated with negative pole of batteries and the N associated with positive pole, then now formed a relationship called “reverse bias”. In these circumstances, the hole (positive charge carriers) can be connected directly to the positive pole, while the electrons are also directly to the positive pole. So, clearly in the PN junction there is no movement of majority charge carriers either the holes or electrons. Meanwhile, the minority charge carriers (electrons) in the part P moves trying to reach the positive pole of the batteries. Similarly, the minority charge carriers (holes) in the N also moved to reach the negative pole. Therefore, in a state of reverse bias, in the PN junction there is also output current even in very small amounts (micro amperes). This current is often called the reverse saturation current or leakage current.

.
Anything interesting in reverse bias. When the temperature of PN junction raised they will be able to enlarge leakage current. Means that if given the energy (heat), the minority charge carriers in the PN junction grows. Because the light is one form of energy, so if there is light that hit a PN junction may also produce enough energy to generate charge carriers. This symptoms are called photoconductive. Based on the photoconductive symptoms made of photodiode electronic components from PN junction.

In reverse bias, with increasing intensity of light that hit photodiode can increase the level of leakage current. Leakage currents can also be enlarged by increasing the battery voltage (reverse voltage), but the addition of leakage currents were not significant. When the batteries in the reverse bias circuit is removed and replaced with a load of resistance, the provision of light that can cause charge carriers both holes and electrons. If the illumination light is increased, current output was greater. Such symptoms are called photovoltaic. Light can provide enough energy to enlarge the number of holes in the P and the number of electrons on the N. Based on the symptoms of this photovoltaic electronic components can be created photovoltaic cell. Because usually the sun as a source of light, the photovoltaic cell is also called the solar cell (solar cells) or a solar energy converter.
So the solar cell is essentially a large photo diode and designed by referring to the photovoltaic symptoms so that could produce the greatest possible power. P type silicon is the very thin surface layer so that light can penetrate directly reach the junction. Part P is given ring-shaped nickel layer, as a positive output terminal. Under the P is the N type that is coated with nickel as well as the negative output terminal.

To obtain a large enough power required much of solar cells. Usually, solar cells arranged form the shape of the panel, and is called the photovoltaic panels (PV). PV as a source of electric power was first used in satellites. Then PV as an energy source for cars, so there are solar electric car. Now, in foreign countries, PV has started to be used as a roof or wall of the house. Sanyo has made even a semi-transparent PV that can be used as a substitute for glass.

After getting the output of the solar cell is a direct electrical current can be used to load utilized. But also the electric current can be used as a charge stored by the battery to be used when needed, especially at night because there was no sun.

If the solar cell is used for storage into the battery, then the resulting voltage magnitude must be above the battery specification. For example the battery used is 12 volts, the voltage produced by solar cell must be above 12 volts in order to perform charging.

We recommend that before carrying out the charging battery should be empty because the incoming flow will be filled with the maximum. The unit capacity of a battery is the Ampere-hour (Ah) and these characteristics are usually found on the label of a battery. For example a battery with 10 Ah capacity will fill up for 10 hours with the solar cell output currents of 1 Ampere.

Solar Residential Energy: What is it for?

Solar energy: this term basically does not cause a stirring in the mind as the explanation that comes at hand is indeed too simple. Everyone knows what is meant by solar energy, and that is, the energy that comes from the sun. In its most basic sense, solar energy and other solar residential equipment are nonetheless environment-friendly and not risky at all. But then you need not become one fine environmentalist first before you will be able to come across with whatever advantageous benefit solar residential energy has.

Why is the solar residential energy said to be environment-friendly? What are its general benefits? Practically speaking, when solar residential energy is used, the electrical bills tremendously go down as compared to the other type of residential energy available for all people. Why would you pay for such expensive bills when all you need to do is to employ solar residential energy?

Another major advantage of the solar residential energy is the absence of the very complicated and dangerous wiring. Solar energy lights in the garden path or any other solar energy-powered items used in your residential are ready to be installed less the wiring to be dealt with. In reality, these solar light bulbs are equipped with darkness sensors so they need not be turned on to give off light and they need not be turned off as well when they are no longer needed.

As a sort of simple explanation, the solar light bulbs will simply have to be purchased, taken out of the boxes, installed, and then presto! You just have to situate them where you want them to be and never worry about them ever again.

A List of the Benefits of Solar Residential Energy

Why is the solar residential energy equally beneficial? Why is it more recommended for use? Here are some of its benefits which are truly worth the attention to be graced by anyone:

Solar residential energy is environmentally friendly. As mentioned a while ago, solar residential energy will not harm the environmental features. It is specifically clean and renewable as well. More so, it does not cause pollution just like what the rest of the traditional electrical forms do.

Solar residential energy systems need the least maintenance. They are not fuel-powered so no need to buy the refills.

Solar residential energy makes you save a lot of money. The energy that is derived from the sun can be accessed for free as you make use of solar lights, solar panels, and the likes. The federal government most of the time gives out financial incentives. You don’t get affected by the rise of the fuel rates since you are using solar residential energy.

Making use of the solar residential energy makes you entirely independent from the foreign and centralized energy sources. Power outages will not likely affect you in any manner.

Most of the solar energy items are very easy to install thus lessening the complicated work of the wiring systems.

Some Common Disadvantages of the Solar Residential Energy

Of course the disadvantages will not be taken aside. Here are some of the most common disadvantages of the solar residential energy:

The employment of a solar residential energy can be expensive at first. But as time passes by, it becomes light to the pocket.

The strength of the solar residential energy will relatively depend on the location of your residence in relation with its facing to the sun. Also, the area of your residence is another point to consider. You will need large areas to install the solar panels.

The Various Solar Energy Items

There are lots of solar energy devices that you may opt to buy. Included are the solar flashlights, solar heaters, car ventilators, solar video cameras, solar radios, solar pool purifier, solar mosquito inhibitor, solar lighting, and solar fountain pumps.

What You Must Do

Back in the earlier years, solar energy powered devices were very costly that very few homeowners made use of the solar residential energy. But these days, small volumes of solar energy devices are put up for sale therefore making it affordable for all. If you don’t have enough money to fund these items you can always start small.

Solar Heat

July 05, 2009 By: Admin Category: Solar Heater

Active and Passive Solar Heat

Utilization of solar energy in architecture can be done in two ways: passive and active. Utilization of passive do when solar power does not need to converted first into electricity. Deep utilization of the passive is also included on space heating (using the greenhouse gases) for the region with temperature of the air low, and water heating. Also, techniques to prevent heating the air in the room on the building in the area, including Tropical into the use of the passive type, where component of sunlight, which consists of: light and heat, only used on components’ light ‘it – the need for natural lighting in buildings.

Passive design strategies will be very different between the buildings that are on climate Tropical and climate Sub Tropical / cold. At the Tropical climate, direct radiation from the sun tend to be avoided by building in order to heat gain in the building to be low, so the increase of air temperature in the building can be prevented. While in Sub-Tropical climate, the design strategy is a passive step of the Tropical climate strategy in the acquisition of heat sun tend to be maximized (except in the summer), solar radiation through that fall directly on the building so that temperature increase occurs in the building, considering the air temperature around is low.

In utilizing the solar actively using the photovoltaic, should also simultaneously architect implement the strategy of passive design. Without the application of passive design strategies, energy use in buildings very likely remain high when visual and thermal comfort must be achieved. In situations such as this, the electric power comes from solar power conversion by solar cells does not become too much meaning. With dimensional solar cell panel which needs large electricity for the achievement of thermal comfort and visual on the building difficult to fulfill. Still electrical energy required for engine cooling air with a large capacity, because the air temperature in a high building, also required electricity for lights in the torch-lighting building a dark room when the strategy passive design that lead to the energy savings are not applied. Role of solar power to replace electricity necessary to achieve the building comfort (thermal and visual) finally failed because the building was not designed in such a form so that comfort achieved without the many electric energy consumption. Electricity generated by the photovoltaic possibility will not be large enough to cool down and illuminate the building. In other words passive design considerations for the use of energy in buildings in this case can not be ignored.

In the passive design, objectives of architecture work that would be achieved – that is comfortable and aesthetic, are generally made integral. Each step in the preparation of the components to form the jacket, simultaneous will result in the achievement of buildings comfort and aesthetic. Be not so with the case where the design of active solar cell panels can be arranged separate components with the preparation of building casing. In other words, the achievement of building aesthetic in active design done in a more flexible and separate with the strategy of comfort achievement, although in fact the architects are required to thought to integrate a comprehensive comfort needs with aesthetics – between needs using a solar cell panel with place them on the integrated shroud of the building so that the panels at once can be a building aesthetic element.

How Solar Power Plant Installation

Solar Power Plant is a system of clean energy and produce electricity from sunlight. Also support the issue of global warming. Because energy is widely used by State Electricity Enterprise is the energy that can not be renewable (fossil) fuel such as kerosene, gas, coal, etc. Whereas current cost of fuel has begun to become dearer. If using the sun is free energy available abundant.

Installation and Operation is very easy, enduring long and a very inexpensive investment option to be public at this time. Can be used to meet electricity needs anywhere, especially in rural areas or areas that do not (not yet) reached by State Electricity Enterprise network.

Various Benefits of Using Solar Power Plant:

Source of energy that never runs out and is very environmentally friendly
Can be used anywhere, especially areas that have not yet reached by State Electricity Enterprise network
No need to pay State Electricity Enterprise
Without fuel and pollution-free
Not require special treatment
Free from all treatment
Can be used to light a variety of electrical equipment, especially for lighting the lamp, radio, cassette, TV
Can be used for emergency lighting when electricity of State Electricity Enterprise, have extinction (power off)
And so on

Principles of Sun Power Plant

In the daylight the solar panel receives light (rays) of the sun and then converted into electricity through the Photovoltaic. Electricity generated by solar panels can be directly channeled to burden or stored in Electric Box System (EBS), before use to load, light, radio, TV etc.

At the night, where the solar panel does not generate electricity. Electricity that has been collected (stored) in a Electric Box System (EBS) will be used. To turn on electrical equipment, especially the lighting, etc.

Components of Solar Power Plant

1. Solar Panel:
Change the sunlight into electricity. Modular form of the solar panel provides the ease of the electricity needs for various scale of the needs.

2. Electric Box System (EBS):

Set of traffic from the solar panel to the load
Saving electric current generated by the solar panel before used to drive the load. Burden can be a lamp, electronic device and other equipment that requires electricity
Very flexible in placement, you can take shift about.

The Design of Solar Power Plant – The Practical and Flexible

With a flexible design that can be possible to increase the capacity of electricity with solar panels only add (maximum 2 solar panel) for each package.

Installation HOW VERY EASY

Place solar panel outside the house (roof, roof tile, or make your own tower, etc.) directly to the sunlight adjust with the situation / place / situation you secure place
Pull cable from solar panel, and enter plug to EBS IN DC (There are DC IN and DC OUT) Plus ON-OFF if you use (do not forget to note the ON-OFF key If you use ON if not used right OFF). For a cable if less in length you can add/connect your own. Set EBS & cable installation neat and safely out of reach of children etc.
If solar panel at work, on the EBS have red indicator lights, when charging energy from the panel to EBS will be full, red indicator light will turn on flicker, if it is full will be off. Green indicator lights mark the flow you are working.
In the EBS (Electric Box System) have stop contact Out AC is useful to set the electronic equipment appropriate with watt and energy saved. You can also make your own plug combination for parallel needs. (Many stop contacts that have sold in the market with 2 holes, 4 holes, 6 holes, etc.) find the high quality.
Ready to use to set the lights, tv, radio, etc

Solar Electric Power Systems

Solar system has a mechanical and electrical components that can convert and store electrical energy that can be used to run your home. Start the calculation that you want to do is an energy audit. You need to evaluate the amount of power that will be needed per day preferably in kilowatts / hour. So the need to consider is the location of your home. That will determine the type of solar system you need is a factor such as climate, number of days of peak sunlight per day, average rainfall and number of days of peak sunlight per year. This calculation can be done by companies that make solar electricity system, and they will guide you in choosing solar electric power systems that are appropriate for your home.

Solar electric power system consists of several components. Some of the components that you will find in the solar electric power system is a primary collector, an inverter, a circuit breaker, battery, charge controller, for collectors and mount the display panel. Collector is a component that collects the sun’s energy. In normal cases, is a solar panel collectors. Collectors on the roof is still using the cushion. Location of solar panels is very important and must be in place where the sun will fall in the maximum on it. Is the ideal place solar panels on the north-south as it will ensure that even if the sun from east to west, the panel get the sun for longer duration.

Inverter is the component that will convert the 12 volt DC power to AC power. Based on the location of the power inverter can convert the 110 volt DC to 220 volt. One of the most important component is the circuit breaker or fuse box. This component has a switch and fuse is important to set the transfer energy from the solar panel to the battery or directly to the outlets. Circuit Breakers control the amount of power that will flow to the outlet and will act as security devices for the application.

If you want to have the storage, then you need to buy one or more batteries depending on your needs. If you have then you need a battery charge controller. This component will ensure you are not over or less in charging battery that will reduce the ability of the battery.
