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

Some are 25% now, and don't even break the bank. You can get modules that store the power and feed it back into your house for use later. I kinda want to get some to offset heating and cooling costs.

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.
