Solar energyFlood light

Principle is:

When the surface of solar light, silicon material was part of photon absorption; the photon energy transfer to the silicon atom, make the transition of electrons, a free electron in the P-N junction formed on both sides of agglomerationpotential difference when the external circuit is switched on, the voltage effect, there will be a current through the external circuitry a certain output power. The essence of this process is that the photon energy is converted into electrical energy.

Reminder：

The solar energy lamp is converted into electric energy by the solar energy board, and the electric energy is stored in the battery.

China's solar power industry started late, we do not know much about solar energy, thought that as long as the day light, can be filled with electricity, the night should be light, this is wrong!

International Standard Test conditions for solar panels:

AM1.51000W/ square meters, 25 C

--AM1.5 is 1.5 times the actual distance of light through the atmosphere, which is the vertical thickness of the atmosphere.

--25 is to point to 25 degrees Celsius temperature.

--1000W/ square meters is the solar radiation intensity of light, only at this intensity, solar panels can reach the maximum charging current, to achieve the maximum charging current.

Fall, winter and cloudy, rainy days, light intensity is relatively weak, the effect will be significantly reduced charging, so the lighting time will be shortened, with a reason for solar water heater.

Suggestion: continuous overcast and rainy days, recommend the use of remote control switch switch, save electricity, can extend battery life.
