Outdoor Solar Lights Explained

Outdoor solar lights uses the identical action to generate power as the solar panels on your ceiling (or that you could set up on your ceiling, if you selected to). Essentially, it applies photovoltaic (PV) cells, which accumulate and switch solar energy into electrical energy. The PV cells apply semiconducting materials to engage the sun’s light, which interacts with the silicon and another components to produce electrical energy. The electrical energy runs over cables which power the battery, which in go powers the light. This is an highly simple explanation, but it will present you the common idea of how solar cells play. They can only make electrical energy from direct sunshine, which is why solar lighting wants a battery in order to be able to light up the dark.

So that the batteries to keep a constant charge, the solar light fixture should be in a position that meets full sunshine for almost of the daylight. If it just gets partial sunlight, because it’s barred by trees or other construction, or because your area has much of cloudy conditions, the batteries will run out earlier, and your fixture will supply light for a lower amount of time. Most outdoor solar lights fixtures own a backup power system which applies rechargeable batteries. Solar lights fixtures which apply a small amount of electrical energy frequently apply small AA Ni-Cad or NiMh batteries. But more strong solar lights fixtures (like head lights) apply a covered lead acid battery.

Photo detectors that automatically evaluate light degrees (like the kind that tells your photographic camera when to apply its flash) are constructed into the solar lights fixtures. They monitor light degrees and turn the fixture off at morning and on at nightfall. But get sure there are no artificial light sources (like a street lights or head light) that may contribute a wrong reading and forbid the light from turning on.

Outdoor solar lights usually utilizes LED bulbs. They apply less power than incandescent bulbs and, with a lifetime of around 20 years, are much longer-lasting. Until lately, solar lights overall has not been as bright as lighting powered straight by direct current electrical energy. But the earliest super bright LEDs can at present illuminate as well as halogen bulbs.

New Solar Technology

Solar technologies is now highly developed, with some progress is being developed to be used every day.

Below 10 Solar Technologies to note:

1. Water Heating Solar Panel: Pyron Solar Triad uses a special design, short focal-length, lens in the acrylic concentration to reflect and accept the light, effectively concentrate 6.500 solar power in the form of a small light. The second lens capture light and focus on PV cells. According to related companies, HE Optics System produces 800 times more energy than the silicon solar cells.
2. Home Solar to Hydrogen Storage: An MIT professor Daniel Nocera, build a company this year to market a technology that can split water and store solar energy. The key of this company is to achieve a breakthrough solar energy to make solar power cheaper.
   “The idea is to use solar panels to power the electrolyzer to produce hydrogen which would be stored in tanks. When people need electricity, the stored hydrogen would put through a fuel cell.”
3. Solar panel roof that can be printed and painted: If solar power is easy to install as to paint your roof with sunlight resistant paint, it will lower the standard for the installation of solar power at home. This technology called silicon ink, and according to the U.S. National Renewable Energy Laboratory, solar cells showed 18% energy savings.
4. Large Panel Solar Film: SunFab ™ system uses silicon thin film technology to market the largest and most powerful panels in the world and combines inexpensive material.
5. Organic Solar Concentrators: Engineers at MIT have created a method to transform glass into a high-tech solar concentrator, using color glass to collect and emit light which is usually missing from the panel surface. This technology can create a building for use with glass window film to gather strength. Other companies, GreenSun, has developed a panel of light color where it catch the other parts of the spectrum of the sun, and does not require direct sunlight to work.
6. Space Based Solar: Japanese are developing a giant space station with solar power generators to transmit solar power to earth from 36.000 km above the earth within the next 30 years. The Japanese Government supports $ 21 billion project, which includes a space station solar power with solar panels cubical 4km, save electric energy of 1 gigawatt, enough for 300,000 homes in Tokyo.
7. Solar Roads: Solar Roadways concept, will make a way to use glass panels to collect and distribute solar energy to illuminate the light at night and hot in winter, with enough remaining energy to light homes and businesses. Discoverer, Scott Brusaw, estimating each mile of solar panels can be illuminated 500 houses, and is expected to make a panel for 12×12 need cost about $ 5,000.
8. SunCatcher: Stirling Energy System, contains a solar concentrator in the bowl structure supported by a convex mirror, can be used in Arizona soon. SunCatcher using glass system fitted with a parabolic bowl for concentrating solar power in high-efficiency Stirling engine, with each bowl produces 25.000 watts.
9. Solar Nanotechnology: Research workers at McMaster University in Ontario has developed a light-absorbing nanowires formed of excellent photovoltaic materials in thin but durable carbon-nanotube fabric. They also use small particles in a flexible polyster film where can lead to solar cells that are both flexible and cheaper than today’s solar cells.
10. Grid Ready for Solar: Andalay AC solar energy panels, made with Akeena Solar technology, integrate the racking, wiring and electrical grounding components to the panel. According to the company, this will against the damage, a lot of money in saving for 30 year lifetime. Andalay AC solar energy panels produce a safe AC power, and can be a safe installation process for users.

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

1. 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
2. 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.
3. 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.
4. 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.
5. 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.
