My system generated 14.36 MWh in 2022, which comes out to roughly $4,308 USD. The ROI is about 5-6 years for the system itself. But a new roof was also in order

My system generated 14.36 MWh in 2022, which comes out to roughly $4,308 USD. The ROI is about 5-6 years for the system itself. But a new roof was also in order.... so more like 10-12 years. Still a great deal if you can afford to invest for the long term. Especially with a 30 year warranty on most of the equipment.
- timerol 4y agoAnother way to say that is that you installed solar panels and they paid for your new roof
- webinvest 4y agoHow does having solar affixed to your roof affect or complicate getting a new roof on your home every 10 years?
- ShakataGaNai 4y agoWell you need to have the solar removed before you can get your roofing work done. Then re-installed afterwards. Typically roofing and solar work is very different, so two different companies involved - just makes things a little more complicated. Most solar companies that I've spoken to won't (or will strongly recommend against) installing solar on roofs with less than 10 years of useful life remaining. That being said, roofs typically have a 30 to 50 year lifespan. Depending on the material, location, etc. Most quality solar panels have a warrantied life of at least 25 years. So if you're like me and had an old roof, that gets replaced first before solar gets installed. And by the time the solar panels are EOL, the roof will be close to it as well. So they'll both get replaced again. Assuming I'm still in the same house in 30 years time.

- ShakataGaNai 4y agoWarrantied by the installer, whom has been around for more than 30 years. Also warrantied by the OEM. Which is small names like "Panasonic".
