    A solar system large enough to power a computer and a few small systems would cost about $800, and are about 16″X24″, so four to five times that size to power an air conditioner.  Solar systems large enough to power a house can be purchased for around $15,000-$20,000 dollars, 30% of which is tax deductible. 

    If you’re looking to change your hot water heat over to solar power, Solar Thermal is the most cost effective way to go.  A solar thermal system usually costs about $4,000-$5,000 dollars to power an average home.
