I mean, Western PA is one of those places where it's probably not worth the cost *now*, but will be in the near future if prices of solar equipment keep coming down. It would be really nice to have this sort of resource to help decide if/when to install solar power.
although, the screenshot I included in the first post was from around my dad's house, about 30 miles south of where I am. Mostly because I have a small roof that only has east/west exposure, so it is not an option for solar. But just tried a number of the homes around my neighborhood with southern exposers and they all came up as not feasible (Washington). Tried a few across the river in Oregon and they all calculated as a savings. so, it appears they have some work to do.
@SolarCity will do the analysis for more addresses for free. They ask for some electric usage history, then bring up google maps and look at your roof/direction etc and then let you know if they think it could work. Next step after that is an in home visit to discuss options, then if you want to proceed more next step is a structural survey etc.
