This article is on making an inexpensive Solar power kit. Those that have access can order most parts through the internet, but the batteries need to be locally purchased. The estimation on the power from this less than $600 unit is as follows: 1KWh And could run a 20-inch tv for 20 hours, a portable stereo for 100 hours, a laptop computer for 40 hours, or a 12-watt compact-fluorescent light bulb for 80 hours.
Imagine living in UG and enjoying a nice night reading to your children and then the load shedding kicks in killing all power for your house. With this set up, you can power several lights during this time, and not have to depend on constantly buying parafin (sp) for your lamps. Just because the Power is out doesn't mean the energy is gone.
Also remember that the batteries have to be deep cycle, and can be bought at most marine stores (Used in boats).
