How much would cost to put solar panels on an average size house?
Jul 5th, 2009 by admin
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.
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.
