Solar Panel Installation – How to Do It
Executive Summary about Solar Installation by Gio Rigt
Make sure you choose the perfect location for you solar panels. Nothing should block the solar panel from receiving sunlight. A little bit of shadow blocking the panels reduces the amount of energy the solar panel produces tremendously.
Place the posts first and attach metal rails to the posts on your roof. Attach solar panel mounts to the solar panels, the roof-ground mounts will suffice.
After installing the solar panels, connect them to the inverter. When it comes to inverters, the synchronous solar panel inverter is the best affordable choice.
The solar energy is stored in a battery, excess energy is sold back to the utility company. If there ever is a situation where you do not have enough energy for your house, the utility company will supply the energy through the solar panel converter.
You are done with your solar panel installation.
Solar Panels – Professional Installation Vs Do-It-Yourself
Executive Summary about Solar Installation by Tina Metcalf
There is a product available on the internet called Earth for Energy. For about $40, they will send you a PDF or Adobe file with information on how to make or build your own energy efficient green devices.
Supposedly, for a fraction of the retail costs, someone should be able to construct windmills, solar cell panels and other green related things to either augment your electrical consumption, or ultimately, get yourself off the grid completely. Thinking efficiency all around, it would be so much easier, and in the long run cost effective, to find reputable dealers that build and manufacture green technology, like solar cell panels. My thought is this; go with a local solar installer (like Cooler Planet), let them sweat the details, add on a little at a time as your budget allows, and enjoy your life.

Solar Heaters for Swimming Pool – Enjoy Swimming in October
Executive Summary about Solar Heaters by Tanya Turner
Are you thinking about buying a swimming pool heater? A very cost effective option would be getting a solar heater for swimming pool.
Solar heater for swimming pools – how does it work?
Unlike other types of solar powered devices, solar pool heater works rather simple. Solar panels collect heat from the sun. A pump forces water from your swimming pool through a filter that leads it into a solar collector. The size of a swimming pool heater you need depends on the size of your pool and the climate in your area. For bigger pools and colder places you need bigger solar heaters. Heaters with 2′x20′ panels are the most popular. For bigger pools you will need more panels.
Installing your solar pool heater
Unlike solar water heaters, pool heaters are fairly easy to install.
Maintaining your solar heater for swimming pool
Getting a solar heater for your pool makes much more sense than getting any other type of pool heater including gas and electric heaters.
Pool Solar Heaters – How to Build Your Own Pool Solar Heater
Executive Summary about Solar Heaters by Benjamin Robert Ehinger
Here is a plan to put together your solar heater.
First, you are going to need about 150 feet of long black tubing that is about a half inch around to three fourths of an inch around. You will also need about 10 feet of PVC pipe that will fit snugly into the ends of the black tubing. you will need a shut off valve that will be attached to one end of the PVC piping. You will also need a pump that will be strong enough to move water through the tubing at a slow speed.
Second, you are going to need some 2 by 4 pieces of lumber and some metal brackets. You will want to mount this part of your heater on a rooftop that is in direct sunlight, a shed, a barn, a garage, or anywhere else that is in direct sunlight.
Last, you will run the PVC piping from each end of the black tubing into the pool. When you turn the pump on it will suck water out of your pool at a slow speed and pump it up and through your black tubing, very slowly. You want this water to be sitting in the black tubing and getting hot. Then, when it comes back into the pool it will start to raise the temperature of your pool. This is now your solar pool heater.

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.
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.

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 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 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
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 House Plans – The New Wave Of Our Future
Executive Summary about Solar House by Ernest Jarquio
Environmentalists rejoice! What is this new technology that will help save the earth? Why, solar house plans of course.
What Are Solar House Plans?
Well, the new phase in home planning is the plan for a sun-powered home.
The designer begins by drawing out the floor plan, planing to use recycled materials, eco-friendly building supplies and Energy-Star electrical outlets. For instance, the concrete slab flooring stores solar heat during the sunny days, then releases it at night, keeping the house warm.
The designer uses only eco-friendly items for these tasks, such as recycled wood and green material for the insulation. After all this is planned, they continue onward to Energy-Star appliances and other electronic devices.
The other panels installed are the thermal water heaters, which provide hot water constantly for the entire home. This hot water is often more reliable than a traditional hot water heater, supplying plenty of heat for the laundry, kitchen and bath.
How to Plan Your House for the Sun
Executive Summary about Solar House by Naomi Kendell
Every house will gain heat throughout the day as the sun shines through its windows.
And during the night as the temperature drops, this same house will lose heat to the outside through its walls, windows and roof.
By facing your house to the south (in the northern hemisphere) you will gain the rays of the winter sun. Afternoon sun comes from the west, so rooms like the dining room and living room can be placed on this orientation. The southwest corner of the house will be the sunniest – winter and afternoon sun.
On the northern side of your house, place service rooms.
2. Window Sizing
Out of all the materials your house is made of, windows lose the most heat. There is a balance here, because windows allow sunlight into your house. However even triple glazed glass allows more heat to escape than a well insulated wall.
The first is where your windows face. If you have most of your windows on the northern side, these windows will not get much sun during winter. They will be losing heat, but not gaining solar energy.
There is an optimal ratio of windows:wall for every climate. For instance in temperate climates, a window to wall ration could be: 30% window area to 70% wall area. The other ratio is in windows and orientation.
For instance, highly insulated walls will keep the heat inside your house. When analyzing your heat loss through your windows, you can gain some leeway through insulation. This air forms and insulating layer, slowing down heat loss.
Another way to use materials in your solar house plan is to take advantage of heat storage. It is radiating heat. The floor is insulated underneath to prevent heat loss. A well designed thermal heat sink will stay warm all night long.
Shading is an important part of the solar house plan. This is important not only for heat gains, but for preventing heat gains. In temperate climates as well, shading can be used to keep summer sun out and let winter sun in.
Using our orientation principle: your house is facing south. During the winter the sun angles low and reaches far into the house. This same shading will allow winter sun into your house.
Your latitude effects the angle of the winter sun. In conclusion – solar house plans are a great way to design houses that are warm and comfortable to live in, and save you money off your heating and air conditioning bill.
Using Orientation, Window Placement, Materials and Shading, you can design a house that responds to its environment and creates its own micro-climate of comfort.

Solar Batteries – Deep Cycle
Executive Summary about Solar Battery by Michael Motley
Batteries are separated into two categories, by application (what the battery is used for) and construction (how the battery is built). Deep-Cycle batteries are the battery of choice for most installations because of the way they are made. Deep-cycle batteries are made to be run completely down relatively fast, and recharged just as fast, constantly. The major applications for deep-cycle batteries are solar electric (PV), backup power source, and boat/RV batteries.
There are 3 main construction types at this time:
Flooded batteries are what most people think of when thinking of batteries of this size.
Gelled Batteries or Gel Cells are sealed, and some are valve regulated. They contain gelled acid that was gelled by adding silica gel, making like a battery acid jelly.
AGM (Absorbed Glass Mat) batteries are similar to the gelled batteries but they also have fiberglass mat between the plates of the batter, which is then filled with gel. These batteries are the premier choice if you have any concerns about spilling of battery acid.
The main difference in deep-cycle batteries is thicker plates. The thicker plates allow the deep-cycle battery to be discharged down as much as 80% over and over again. The battery with the thickest plates will last the longest
A battery cycle is one complete discharge and recharge cycle. How deep a battery is discharged directly affects its life span.
There are many variables to deep-cycle battery life. The standard flooded battery 1-6 years. In the deep-cycle family of batteries, the AGM has one advantage over the other two types in it’s class. There is a myth that you shouldn’t store batteries on concrete floors.
Battery Quick Facts
* Almost all batteries have to be cycled 10-20 times before being able to reach full capacity.
* Always keep vent caps on your flooded batteries when charging.
* Lead-Acid batteries do not have a memory. Use only clean water to clean the outside of batteries.

Executive Summary about Solar Battery by Anne Clarke
People are realizing that they can easily change the way that power is created. For two centuries the world has relied upon fossil fuel, mostly coal and oil, for almost every form of power. It lights our homes, powers our appliances and drives our cars. Unfortunately fossil fuels rely on combustion to release their power. Solar power is an effective way to harness the power of the sun, something plants have been doing for millions of years. It can produce more power during the day than the average home uses. Most houses will use less power during the day, and much less in the summer which is the peak power producing time for solar panels. To be effective this power must be stored somehow.
One popular way of storing solar power is by connecting the solar panels to the existing electrical grid, effectively turning it into a massive solar battery. At night power is taken from the grid as usual. Any power outages can still affect these solar panel set-ups, but no rechargeable batteries have to be used.
Rechargeable batteries are notoriously short lived and expensive. They either have low power flows for a long time with a good capacity, or they have high power flows for short times with poor capacity. Typical batteries, especially lithium ion, have high capacity for storing power, but deliver a weak output and recharge slowly. The ideal solar battery would be able to charge quickly, have a high density for storing power and be able to emit as much of that power as is needed.
