I'm working in East Timor (6 degrees South of equator, tropical climate) and need to set up computers in the District Employment Centers. They do not have electricity during the day, but most days from 6 to 12 pm.
I'm looking at the best method to have enough power to run a desktop PC (consumption ca. 65W?) for 4 to 8 hours a day - be it using solar panels or accumulators or what ever. Can anyone give me advice on what area of solar panels I might need (we get LOTS of sun - in the dry season at least) and a ball park figure for what capital investment we would need to make (to the nearest $1,000) with solar panels, inverters, batteries etc.?
