Solar panel Solar panel
Classification: crystalline silicon panels: polycrystalline silicon solar cells, monocrystalline silicon solar cells.
Amorphous silicon panels: thin film solar cells, organic solar cells.
Chemical dye panel: Dye-sensitized solar cell.
Power system
The solar panel solar power generation system is composed of a solar battery pack, a solar controller, and a battery (group). If the output power is AC 220V or 110V, you need to configure the inverter.
The role of each part is:
(1) Solar panels: Solar panels are the core of solar power systems and the most valuable part of solar power systems. Its role is to convert solar energy into electrical energy, or send it to a battery for storage, or to drive a load (using electrical appliances) to work. The quality and cost of solar panels will directly determine the quality and cost of the entire system.
(2) Solar controller: The function of the solar controller is to control the working state of the whole system and to protect the battery from over-charge protection and over-discharge protection. In places with large temperature differences, qualified controllers should also have temperature compensation. Other additional features such as light control switches and time control switches should be optional for the controller.
(3) Battery: Generally, it is a lead-acid battery. Generally, there are two types of 12V and 24V. In small and micro systems, nickel-hydrogen batteries, nickel-cadmium batteries or lithium batteries can also be used. Its function is to store the electrical energy emitted by the solar panel when there is light, and then release it when needed.
(4) Inverter: AC220V and AC110V AC power supply are required in many occasions. Since the direct output of solar energy is generally DC6V, DC12V, DC24V, DC48V. In order to supply electric energy to an AC220V appliance, it is necessary to convert the DC power generated by the solar power generation system into AC power, so a DC-AC inverter is required. In some cases, when a load of multiple voltages is required, a DC-AC inverter is also used, such as converting 24 VDC of electrical energy into 5 VDC of electrical energy (note that it is not a simple step-down).
