Very long term however it generally isn't a better deal. 15 years with solar is generally no maintenance with linear gains beginning about halfway through. Compared to 15 with a combustion engine that loses value the day it's installed, needs permanent maintenance to operate efficiently and effectively, and only generates value (ha) during disruptions.
- boringg 2y agoSolar actually runs into inverter problems by year 10. Roof needs to be redone maybe year 20 if you installed with a new roof. The back up generator is really compared against the energy storage asset and not the solar array. On a multi-day/weeklong winter grid failure generator is a much safer asset to have to protect the home - even including your loss equation.
- 1970-01-01 2y agoInverters are built to last for the life of the solar system. They typically have 10-15 year warranty. And no reputable solar installer is going to put panels on a roof that is due for replacement. By the time a roof needs to be replaced, the panels have already paid for themselves and can be swapped out for newer, cheaper, and more efficient models. That's Swanson's law.
- boringg 2y agoI can speak from first hand experience that the comment about inverters is inaccurate. You may need to replace them they are the weakest link in the balance of system. 2nd - much nicer to not have to waste a paid off asset at year 20.
- 1970-01-01 2y agoI can also speak to this. Mine have been trouble free since 2015.
