Is it profitable to buy a Battery Charger Solar panel and batteries, a cheap power inverter and a light?
using the network vs. power all the time? I'm thinking about doing this and put in the lights of one or two key sites were my family and I all means have a light at night during a hours per night. i could use the lights more or less depending on the battery.
Configuration that reduced rate is very unlikely that more cheaper than the mains. If you want a little light at night, get one of those LED ones. They use half a watt, which if left in the year, is only a few cents. If you mean the regular room lighting, consider that if there were a couple 25-watt compact fluorescent bulbs, which would be $ 6 per year or less electricity, if you used two hours per night. Compare that with the price of solar installation.
