How can i build a solar power system that can supply all the basic appliances in our house?
Question:
Answer:
Solar energy is horribly inefficient, it only converts appx 3-4% of the energy available it, it costs a fortune to. i would suggest using a different form of renewable source. use solar energy to heat you water (very simple non-electrical system - black hose-piping within a black box - supprisingly effective for what you may thtink it is, this also saves money on electricity.
You could convert your central heating to a heat engine system (loads of info online about it) - expensive outlay but unlike solar cells very efficient with it.
other than that common household electrical requirements nowadays are sickening and really need the national grid juice to power it. If you have a river/stream by your house tha can easily be harnessed to power all your lights, refridgerator and basic amenities ... - however how many ppl actually have a stream... LUCKY BAS***D'S!
Good luck with What ever you do, any one cutting down their fuel useage is good!

If you have to ask -either quit while you're ahead-or try Popular Mechanics website. You will very likely find that it is an economical folly to even begin to think you'll save $ Especially if you need 120 AC
check out the BP solar energy web page not only do the sell the equipment they have a calculator function that can help you determine what number of panels etc you need there is a lot of difference in a stand alone system and a grid system for most cases a grid tie system is the cheaper and better choice this type system can be built with generator or battery backup but with your house tied to the grid the grid is in effect your back up as for price a 100 watt panel can be had for around 250 U.S.
ITS TERRIBLY EXPENSIVE.
