To those on this forum expressing doubts about the solar panels. They just about all come with an output guarantee of something like 80% after 25 years. They degrade slowly. Like a tractor - a solar panel is not just "one thing." It is a bunch of solar cells wired together with blocking diodes. They can be repaired when needed. In regard to the silicon cells themselves -it has been proven long ago that they can last 50 years or more. Many of the first solar-powered satellites sent to space 50 years ago are still making power. Like the US Vanguard sent up in 1958.
Solar panels are of little concern. The expensive electronics like inverters and controllers are what's going to cost money to maintain.
