(1) Single Crystal Silicon Solar Panels
Monocrystalline silicon solar panel conversion efficiency of 15% to a maximum of 24%, which is all kinds of photoelectric conversion efficiency of solar panels in the highest, but the production costs of large, so that it can not be a large number of broad and widespread use. The general use of glass and silicon resin waterproof package, so its durable, life in general up to 15 years, up to 25 years.
(2) Polycrystalline Silicon Solar Panels
Polycrystalline silicon solar panels and solar panel production process is almost, but the polycrystalline silicon photoelectric conversion efficiency of solar panels will have to reduce the number, the photoelectric conversion efficiency of about 12% (July 1, 2004 listed on the efficiency of Japan¡¯s Sharp 14.8% The world¡¯s most efficient silicon solar panels). Speaking from the production costs, cheaper than some of monocrystalline silicon solar panels, materials easily, saving power consumption, the total production costs low, so are a lot of development. In addition, the polycrystalline silicon solar battery life is also shorter than the single crystal silicon solar panels. From the cost performance is concerned, single crystal silicon solar panels is also slightly better.
(3) Amorphous Silicon Solar Panels
Amorphous silicon solar panels appeared in 1976 a new thin film solar panels, monocrystalline and polycrystalline silicon solar panels it with the production method is completely different, greatly simplify the process, very little silicon material consumption, lower power consumption, its main advantage in low light conditions can also generate electricity. However, the main problems of amorphous silicon solar panel conversion efficiency is low, the current international advanced level in about 10%, and not stable enough, with time, the conversion efficiency attenuation.
(4) Multiple Compound Solar Panels
Multiple compounds that not a single element solar panels made of semiconductor materials solar panels. There is now a wide variety of studies, most yet to industrial production, mainly the following: a) CdS solar panels, b) GaAs solar panels c) of copper indium selenide solar panels (the new multi band gap gradient Cu (In, Ga ) Se2 thin film solar panels)
Cu (In, Ga) Se2 is an expanelent absorber of sunlight, with a graded band gap (conduction band and valence band energy difference between) multiple of the semiconductor material, can expand the scope of solar energy absorption and thus improve the photoelectric conversion efficiency. Based on it can design a photoelectric conversion efficiency than silicon thin film solar panels significantly improved thin-film solar panels. The photoelectric conversion rate can reach 18%, and these thin film solar panels so far found no effect of light radiation induced performance degradation (SWE), the photoelectric conversion efficiency than the current commercial thin-film solar panels by about 50 75% in thin film solar panels are among the world¡¯s highest level of photoelectric conversion efficiency.
Open circuit voltage is not connected to the battery voltage when the circuit can be considered a force.
Short-circuit current is not connected when the electrical current, equivalent to find a wire directly to the battery when connected to the positive and negative current.
Peak voltage \ peak current \ peak power of these concepts correspond to the alternating current, direct current is the peak of the talking. Gu think Italy is the peak maximum, such as point 220 in fact we use RMS, peak electricity then we should be 318. Open circuit voltage is equivalent to take you directly to the amount of battery voltage meter board (which can be seen as a DC power supply) both ends of the voltage; peak voltage is the load during operation after the voltage, so the open circuit voltage> peak voltage> the actual voltage. Our actual voltage of the battery plates, 18 volts and 36 volts two.
A small solar power system, in the case of solar radiation sufficient power to the load is kept by the solar panels to the battery in the first sub powered by the battery out.
Usually connected inverter battery, inverter connected load (electric vehicles, light bulbs). Load to take power from the battery and solar panels to the battery-powered stream: 1) If the load is too heavy will make solar cells charge in short supply, so the load should not exceed the total capacity of solar cells, the load to one tenth of the battery safety Hours of electric current can be long-term use.

France decided to suspend most of the solar project for three months due in part to cheap Chinese imports to contain solar panels, the French Environment Minister Nathalie Kosciusko-Morizet in the France Info radio said. "France installed 90% of solar panels from China, our import standards must be strengthened." Kosciusko-Morizet said, "We are not here to grant the Chinese economy, but to create green jobs in France."
Realizing they are too generous subsidies, the European governments began to change solar energy policy, which allows developers to start buying the major suppliers from China, solar panels, including Yingli Green Energy Holding Company Limited, and as the German Q-Cells SE and Spain¡¯s Solaria Energia & Medio Ambiente SA¡¯s products are in the cold.
In order to study the construction of power plants should be limited to further reduce subsidies paid to the rate of solar power plants, France on December 10 some of the projects suspended for three months. France¡¯s rate of electricity price subsidies, as the highest in Europe, once led to the prosperity of the French engineering applications. France, Spain and Germany followed similar initiatives, is rising as consumers seek to limit the cost of clean energy methods.
Capacity of more than 3KW France suspended the project, as long as the power generation in the 18 months beginning, the Ordinance will allow 9 months ago with the French power company has won a subsidized rate of the project to continue.
