Sitching to Solar lighting Anonymous Sun Feb 24 01:54:42 2013 No.405485 [Reply] [Original]

South African here 220v 50Hz

I want to convert to my house lighting to use LEDs powered by solar.
I have two options -
Solar charger , battery, 12v LED lamps (Efficient but higher current over long cable runs could lead to energy losses)
or
Solar charger, battery, interter, 220v LED lamps (inefficient DC to AC conversion but lower current over cables and less hassle and expense swopping out existing fitting.
