Product Overview



The working principle of solar panels

The solar panel generates current when sunlight hit the cells which are welded in different series and parallel according to 12 or 24V system requirement.Current will charge battery through solar controller which preset with protection function of over charge and over discharge, working duration time for LED lamp. When darkness comes voltage of solar panel will drop down whichtriggers the solar controller open circuit to discharge, and that makes LED lamp turn on.

Mono solar panel:
The photoelectric conversion rate of monocrystalline silicon solar panels is 15%-24%, which is the highest photoelectric conversion efficiency among all types of solar cells. However, the production cost is so large that it cannot be widely used in large quantities.
Because monocrystalline silicon is generally encapsulated with tempered alass and waterproof resin, it is durable and has a service.
life of 15-25 years.

Poly solar panel:
The technology of polycrystalline silicon solar panels is similar to that of monocrvstalline silicon solar panels, but the photoelectric conversion efficiency of polycrvstalline silicon solar panels has to be reduced a lot, and the photoelectric conversion efficiencv is about 12%-14 8% In terms of production cost, it is cheaper than monocrystalline silicon solar panel, the material is easy to manufacture, it saves electricity consumption, and the total production cost is lower.
