    In the 90s, rooftop solar was around 10-15% efficient. Now rooftop panels are closer to 20%.

        That one doesn’t seem like it’s worth it at the regular price though, seeing as it’s only 175W. You can get a 400W QCell Q.Peak panel for the same price or cheaper. I guess it’s useful if your use case needs smaller panels.
