Reply to comment by 25x10e21 in News Release: NREL Creates Highest Efficiency 1-Sun Solar Cell - 39.5% efficiency by TimeSpentWasting

I use about 1200 kWh a month. I live in a townhome so a very small roof compared to a house.

I had someone do a mock-up and it was 17 panels. Is it possible to get 15,000 kWh (or more, I’d like to go ev) out of 17 panels?

In Texas , south east facing roof (relatively flat)

There are many free online estimators where you can enter your exact location and the number of panels or peak power installed (17 panels x 400W = 6.8kW peak power) and it will calculate month by month generation. Some even take into account a typical weather patterns.
