Can I get effective solar on my house?

Image below is from google maps. North is up. Seems like I could put a lot of panels on that SE facing roof. I really just want to get 1000W peak to cover my basic power. I'd probably just fill it up, but not looking for a lot. Location is SW Ohio. If there is a good simulator, I would love to give that a go.

Your house faces the same as mine with as many different angles

I have a 6.6kw grid tied system broken up into 4 different arrays.

10 kw total of Panels are on the south and west side.

My measurements using google came to 3 kw, but the contractor got 10 kw.

These sites helped me a ton.

You could also consider the SE roof, or both.

Photovoltaic Geographical Information System (PVGIS)

PVGIS is a free web application that allows the user to get data on solar radiation and photovoltaic system energy production, in most parts of the world.

pvwatts says I can get 5148 kWh / year with a 4k array. So $532 / year at my current rate.
