My guess is that you are just wondering if it is a good idea. Well, it looks like about $11,000 for 1300watts for a grid tie system. That's 1300watts on the perfect day. From a payback stand point it still tends to take 12-20years for the system to pay for its self depending on your electricity cost and location. Solar to heat is more efficient so solar hot water heat has a better payback. <br><b>References : </b><br>http://www.solarhome.org/solarhomekits.html http://www.solarhome.org/aeesolargridtiesystems.html If you are asking about solar electric, then the amount of electricity you use and if you have a good south facing roof for mounting them tends to matter more than the size of the house.
