- mnkmnk 10y agoHave solar cells become so good that a roof of them can power the whole house?
- gjolund 10y agoI would say the entire roof is overkill for most homes. My brother is able to power his 2000sqft home with less than 50% of his roof covered.
- marssaxman 10y agoThe answer depends on what exactly you mean by "powering the whole house", but "yes" is a reasonable approximation. I had an array installed in 2013 which covers about a sixth of my roof; every year it produces about 40% of the electricity we consume. The story has only improved since then as efficiency of solar cells has continued to rise and cost of installed panels has continued to fall.
- woodandsteel 10y agoThis is designed for new houses. That means to calculate the cost of the electricity, you first need to subtract the cost of an equivalent-quality conventional roof.
