The estimated ROI is about $15,000 over 25 years with my 6.36kW system. Lifetime roof penetration warranty, 25 year service warranty on the panels and 10 year service warranty on the inverter. Solar is much better than you think it is.
They need to standardize the numbers. For marketing it looks great, but 6KW of solar panel is no where near what people are thinking when look at their electric bill. When I was looking at my needs, which peak at about 2.2Kwh of AC in the summer, the equivalent solar systems were like the 6-10Kwh systems.
Plus they need to start incorporating a form of energy storage. Having to rely on utility every day from dawn to dusk kind of defeats the goals people are looking for.
