The sun is a free source of clean renewable power, there is no cost of delivery to your door, equipment prices keep dropping (80% in the last 10 years on average), and utility costs keep increasing. Utility Companies are installing solar PV systems because it can be deployed quicker, has lower operating costs, and is much more safe in the event of a disaster. Solar PV reduces our overall carbon footprint, increases our energy independence, and creating a smaller distributed electrical grid increases electrical resilience, AND you actually get a payback period. It's for these reasons solar PV makes sense no matter your motives.
