The small solar power system is composed of a single poly-crystalline solar panel, battery, and photovoltaic controller. When the output power supply is AC 220V or 110V, the inverter is also required. All in all, solar energy system uses the photoelectric effect to directly convert solar radiation energy into electrical energy. It is often used for household lighting and outdoor camping.

The solar panel is the core part of the solar power generation system. It’s also the most valuable part of the solar power generation system. The function is to convert the radiation capacity of the sun into electric energy, send it to the battery for storage, or push the load to work.

The function of the solar controller is to control the working state of the whole system and protect the battery from overcharge and over-discharge, the qualified controller shall also have the function of temperature compensation, where the temperature difference is large. Other additional functions such as optical control switch and time control switch shall be optional to the controller.

In small and micro solar systems, nickel-hydrogen batteries, nickel-cadmium batteries or lithium batteries can also be used. The function of solar energy storage cells is to store the electric energy emitted by solar panels when there is light and release it when needed.

The direct output of solar energy is generally 12VDC, 24VDC and 48VDC.In order to provide electric energy to 220VAC electrical appliances, it is necessary to convert the DC energy generated by the solar power generation system into AC energy, therefore, a DC-AC inverter needs to be used.

Advantage of it.

Solar energy is inexhaustible.

Solar energy can be located everywhere and can supply power nearby without long-distance transmission, avoiding the loss of long-distance transmission lines

Solar energy does not use fuel and its operation cost is very low.

Solar power generation has no moving parts, is not easy to use and damage, and is simple to maintain and easy to carry also.

Solar power generation will not produce any waste, no pollution, noise and other public hazards, and has no adverse impact on the environment. It is an ideal clean energy.Safe and reliable also.

The construction period of solar power generation system is short, convenient and flexible, and the solar array capacity can be added or reduced arbitrarily according to the increase or decrease of load to avoid waste.

Disadvantage of it.

The amount of solar power generation is related to climate conditions.

Under standard conditions, the solar radiation intensity received on the ground is 1000W / m ^.So the energy density is low.

The initial investment is high.

Easy to carry, easy to be stolen at the same time.
