> You save tens of thousands of dollars and lower your carbon footprint by hundreds of thousands of pounds of CO2 over 20-30 years.
Most consumers don't give an eff about carbon footprint unless it saves them money or the pollution does affect them directly. Also I dont think there are too many people in USA spending tens of thousands of dollars in electricity bill.
Solar Panale is a great idea if there is technological breakthrough but else it a tried and failed model.

They do spend that much, the average in the US is $115 a month, and the spread is lowish, ranging from $90 to $130 a month between states, and up to $150 in outliers like Alaska. Or in other words, a US average of nearly $1.4k a year.
A 10 year horizon puts total electricity expenses at $14k, a 30y horizon you mentioned puts it past $40k.
However, those are not savings like the guy implied that you replied to. Solar today tends to lower your bill by maybe 5-10% on average over large amounts of customers tops. So savings would be a few thousand bucks, not tens of thousands.
More importantly, that's a rate for today, and it remains to be seen how that will develop into the future.
The big untold truth for customers is that there's a high probability that electricity prices will come down sharply. Renewable energy resource price points are dropping fast, both on the hardware side, the soft-market side, and spurred on by subsidies. We've already seen crazy low record rates, like the latest PPA (power purchase agreement) was as low as 3 cents. PPA's set electricity prices for contracts that last well into the future, so they're essentially the industry's prediction for where the market will go. (i.e. a 20 year contract at 3 cents per kwh might look silly when the price is 5c today, but it implies industry experts expect the price to drop such, perhaps to 2 cents near the end, that the average cost level over 20 years will drop below 3c.)
Those PPAs will spread and start to affect electricity prices, 3 cents already undercuts wholesale prices of most coal, gas and nuclear capacity for example. And those wholesale prices will push down retail prices, too, such that existing solar installations on average over 20 years may actually turn out to be more expensive than the market rate, i.e. no savings at all, because their financing assumes rates to stay stable, or drop less than they likely will as far as I can see.
I'm still a huge fan of solar and urge anyone to consider it, but as an investment as a consumer I think it's financial benefits are oversold.
