Ten years ago, about $43,000 could cover your home’s rooftop in solar panels. Today the average gross cost is about $29,000 — and the efficiency of converting sunlight into electricity has nearly doubled in that time.
This effectively makes the cost of an efficient solar roof lower than the average price of a new car in the US, which is now $33,560, according to Kelley Blue Book.
What’s more, this price tag doesn’t account for renewable energy tax credits and other government incentives, so the cost is likely even lower.
