We should be investing solar in lower income communities, as those people could really use cheaper utilities, and any saving they get would immediately go back into their communities.
OP doesn't have to pay the electric bill anymore, but the average residential solar install exceeds $30k before credits. Someone has to pay off that loan...
Not to mention the Chinese factory that manufactured the solar panels is probably dumping toxic waste chemicals into the local drinking water unabated. We're all too busy patting ourselves on the back for saving the world to consider the impact of the whole lifecycle.
That being said, the costs panels themselves make up ~12% of that cost: https://www.nrel.gov/solar/market-research-analysis/solar-in...
Also worth pointing out, in 13 years the cost of panels dropped by almost 90%.
