| solar power system composition, work principle and design |
| Solar power system composition is similar to solar lights, including solar panels ( including bracket ), control cabinet ( including controller, inverter and batteries ).
Solar power systems work principle: the solar panels receive the sun radiation, turn it to electric energy and store it in batteries through charge & discharge controller. If the system output voltage is required as AC, so inverter is needed to exchange DC to AC, then supply electricity to loads.
Solar power systems design needs to know following information:
1> the installation city of system, for example: Shanghai, China. Because we have to check the average sunshine illumination time. Or, it's better if you can tell us the data.
2> load type, power, quantity, work hours of your all home appliances in one day. For example: TV, 100W, 2 sets, 6 hours per day.
3> if the weather is not sunny, how many overcast and rainy days is required? |

| solar lights design |
| The principle for solar lights based on following information:
1> how much wattage of LED lamp is required?
2> how many hours the light will work per night?
3> how many continuous rainy days is required?
4> what's the average sunshine illumination time in the place the lights will be installed?
The above 4 information is very important to design the solar lights, if possible, you can also tell me height of the pole, which type of road, width and length of road etc, and we will design and suggest the corresponding and suitable configuration of solar lights for you. |

| solar lights work principle |
| The principle is simple, the solar panels receive the sun radiation, turn it to electric energy and store it in batteries through charge & discharge controller. When the lighting lowered to 10lux in dusk and the open circuit voltage of the panels is about 4.5V, the battery discharge when charge & discharge controller detected the change. After 8.5 hours of discharge, the charge & discharge controller act to end discharging. The main role of charge & discharge controller is protecting the battery. |

| solar lights main composition |
| Solar lights consist of solar panels(including bracket), LED lamp, pole, controller and batteries.In addition, anti-theft battery box will be supplied which will be buried underground, to decrease the possibility of the battery be stolen. |
