Solarpunk

I just discovered a solar project run by my electrical provider, that allows me to pay for a number of grids, and will offset my usage and electric bills. This is a multi-state large publicly traded electric company, not a fly-by-night outfit. Essentially, this is similar to having my own panels, and being plugged in to sell excess kWs, but the panels are in their solar farm, managed, and maintained by the electric company. The break-even is 12 years, and the life is 20 years. The breakdown risks are insured by them. The negatives are that at exactly 20 years, I would have to do it again.

You are the experts. Are there other risks that I do not see?
