Solar Builder is one of a kind when it comes to pre-estimating energy savings potential, checking solar investment, return on investment and finding major solar dealers across the US. The website is easy to use and all you have to do is find your home on a Google Map and mark the edges of its roof. Solar Builder will then generate a personalized report about the feasibility of implementing solar panels on your roof.

Users can view, download and even send the report to their email. It will contain the estimated cost, solar score for the location, how much energy can be saved, future solar production, and return of investment.
