Not to be too much of a contrarian, but it sorta is a problem if it is too cheap to support the people that are required to repair it and the parts/replacements for stuff that has failed. Plus, in 20-30 years you are going to have to have enough money on hand to replace todays panels, which if energy costs are almost free/negative, you might not. These are somewhat solvable problems (make energy costs just a tax to support the grid and cut out profit from the equation for the public good), but it is a bit of an issue that probably needs to be planned for.

Then it’s not “too cheap”. Charge the price it takes to maintain the production.
