Solar Home Lighting Systems

A solar home lighting system (SHS), converts solar energy into electricity and provides a comfortable level of illumination in one or more rooms of a house. There are several SHS models featuring one, two, or four CFLs (Compact Fluorescent Lamps). The system could also be used to run a small DC fan or a 12- V DC television along with the CFL(s). The SHS consists of a PV module of 18, 37 or 74 Wp capacity, a lead-acid battery (of 12 V and 20, 40 or 75 AH capacity respectively) and CFLs of 9 W or 11 W rating. The system is designed to work for three to four hours daily, with an autonomy of three days i.e. the system can function for three consecutive cloudy days. A PV module is usually mounted on the roof of the house or any other convenient place so that it is exposed to direct solar radiation throughout the day, avoiding any shadow. The module converts incident solar radiation into electricity, which, in turn, charges the battery. The battery is placed inside the house. The battery provides power to the CFLs, and/ or the television/ fan as required. A charge controller presents overcharging and deep discharge of the battery.

The low cost solar lighting kit is an advanced portable solar lighting system, ideal for remote area / village dwelling. It is pollution-free and an excellent replacement for conventional kerosene lamps and lanterns. The low cost solar lighting kit can run 2pcs 6V/0.9W LED bulb and a cell phone charger. The solar energy generated by the Solar Module in the daytime is stored in the battery, and it can back up the LED lamps for 15 hours. How to charge The Solar module should be placed outside in direct sunlight away from shade (e.g. tree, building etc…); south facing in the northern hemisphere or north facing in the southern hemisphere. Remember that shade will move as the sun moves at different times of the day. Position it so that it will not get damaged by animals or vehicles and to reduce the chance of theft. How it works: LED Bulb Lighting The attached 6V/0.9W LED bulb can give enough brightness for kids study and do house work in the night, it is with 3M cables, you can hang it in the suitable place, The bulb can last for 15 ours after the battery fully charge red, or can last for 10 hours per day's charge

Mobile phone Charging: The solar lighting kit can charge most of the popular cell phones in the market
