When solar first started becoming popular, only roofs that were “80% TSRF” — meaning they could produce 80% of the ultimate (100%) — came with acceptable break-even points. By break-even, we mean the point in time at which the system will have paid for itself through electricity savings and green income. But panel prices have come down so much that even 60% roofs have respectable time frames now.

For example, this somewhat shaded roof will pay for its solar in just over 8 years. To this homeowner, that was totally worth it. We’re pretty sure Mother Nature agrees!
