The usage is that ON means current open, OFF means current closed. AUTO is automatically set to turn the lights on from dark to off at dawn. The light starts when the solar panel detects the onset of darkness.
In recent years, more and more families have installed solar street lights, because as long as there is enough sunshine, the street lights can light up without being turned on. This saves the family a lot of money, which can be said to be very cost-effective.
How solar energy works
Sunlight shines on the p-n junction of the semiconductor to form new hole-electron pairs under the action of the electric field of the p-n junction. Holes flow from region n to region p and electrons flow from region p to region n When the circuit is turned on, a current is formed. This is how it worksion solar cells with a photovoltaic effect.
The light-heat-dynamic-electricity conversion method uses thermal energy generated by solar radiation to produce electricity. Generally, a solar collector converts the absorbed thermal energy into steam as the working fluid, and then drives a working fluid. steam turbine to produce electricity.
The first process is a process of converting light into heat; the second process is a conversion of moving heat into electricity and the final conversion process, which is the same as ordinary thermal power generation. The disadvantage of solar thermal energy production is that its efficiency is very low and its cost very high. Its investment is estimated to be at least 5 to 10 times more expensive than that of ordinary thermal power plants.
1. Place the solar light in the sun during the day. The circuitsolar print is fully exposed to the sun, receives light energy and charges the battery.
2. When using it at night, place the solar light in the room where it is to be used. Just like using a flashlight, just turn on the switch. The battery may continue to discharge to maintain the charge. use of light.
3. Repeat the steps during the next day and continue to place it in the sun. If you forget to charge it, the light won't turn on once the battery runs out, so don't do it. forget to place it in the sun during the day.
