We have 30 solar panels on our roof with the majority facing south and the rest facing west. We get a lot of sunshine year round and in the summer temps get as high as 110*. Our electric bills were very high in the summer esp since we heat our pool from time to time and run our a/c all day. Getting the panels have saved us money but we generate a lot of energy to cover our usage. Like HImom we also got a tax rebate. We lease the panels but the installation was free (we did this years ago before solar really took off). You should do a cost benefit analysis to see if it makes sense for you. Look at your electric bills over a two year period to see the trend of usage. Ask a lot of questions and research the company. Call their references and maybe talk to neighbors who have them.
