Hi Janet,
Electric rates are different all over the country. In some places people pay $.08 per kWh for electricity, and in other places the price may be over $.40 per kWh. I've read that the cost for solar electricity is about $.22 per kWh. Where I live in CA, electric rates are toward the higher end, especially in homes using a lot of electricity. I speak with many people who have electric bills over $250/month. It is possible to generate all your electric costs with solar. For example, at my home, my electric bill last year was about $13, for the whole year!
