Solar water heater plate can be directly converted into electrical energy?
solar controller: the role of solar controller is to control the working state of the entire system, and the battery played a charge protection, over discharge protection role in the larger temperature difference, the qualified controller should also have the temperature Compensation function. Other additional functions such as light control switch, time control switch should be the option of the controller;
Solar panels: solar panels are the core of the solar power system and the highest value part of the solar power generation system, which transforms the sun's radiant power into electricity or stores it in a battery or drives the load The quality and cost of solar panels will directly determine the quality and cost of the entire system;
Modern solar thermal technology combines sunlight and uses its energy to generate hot water, steam and electricity. In addition to using the right technology to collect solar energy, buildings can also use the sun's light and heat, by adding the appropriate design Equipment, such as a giant south window or the use of building materials that absorb and slowly release the sun's heat.
Inverter: In many cases, need to provide 220VAC, 110VAC AC power supply. As the direct output of solar energy are generally 12VDC, 24VDC, 48VDC. To 220VAC electrical appliances to provide electricity, the need for solar power systems DC-AC inverters are used, and DC-AC inverters are used in some applications where DC-DC inverters are used, such as 24VDC Into 5VDC of electricity (note that not a simple buck)
batteries: generally lead-acid batteries, small micro-system, can also be used nickel-metal hydride batteries, nickel-cadmium batteries or lithium batteries. The role is to light when the solar panels issued by the energy stored to the need Time to release again.
