Now on the market to sell solar water heater plate can not be directly converted into electricity? The principle of solar energy into electricity complex? A square solar panels can supply 100 watts of light to illuminate how long?
A) solar panel: solar panel is the core part of the solar power generation system, the highest value is also part of the solar power system. Its role is to the sun's radiation is converted to electrical energy stored in batteries or sent to them, or to promote the work load. The solar panels will directly determine the quality and cost the system of quality and cost;(two) solar controller: solar controller's role is to control the entire system, and over charging protection, over discharge protection of the battery. Place in a larger temperature difference, the controller should also be qualified with temperature compensation function. Other additional functions such as optical switch, when the switch should be optional controller;
(three) battery: lead-acid batteries in general, small micro systems, can also be used NiMH batteries, nickel cadmium battery or lithium battery. Its function is to make the solar energy stored to be released when needed.(four): on many occasions, the inverter AC power supply are required to provide 220VAC 110VAC. Due to the direct output of solar energy in general are 12VDC, 24VDC, 48VDC. able to provide 220VAC electrical power, need to DC power generated by solar power generation system can convert alternating current to, so need to use the DC-AC inverter in some occasions, need to use a variety of load voltage, can also be used as 24VDC DC-DC inverter, the electrical energy is converted into electrical energy (note that 5VDC is not a simple Buck)
The solar power generation system consists of solar cells, solar controller, battery (Group), such as the output power for AC 220V or 110V, also need to configure the inverter:
