Said differently the average american household consumes just under 11 000 kwh per year. Solar panels produce direct current dc and your home runs on alternating current ac.

A home that consumes 1 000 kwh per month will normally need between 20 and 30 solar panels. According to the u s. After the energy loss is factored into the equation the total energy production in kwh would be about. So now that we know you need to produce about 6kw of ac output we can work backwards to figure out how many solar panels you need.
