Why are the leases so problematic? If you don't have the funds nor credit score to finance it, why not just rent out the roof space so to speak? Any return you get from it is better than nothing.
Solar leases are the problematic ones (where you pay a percent of the energy you generated). It sounds like a good deal, but the rates increase yearly and the compounded cost doesn't end up being worth it. The author was cash-flow positive on a fixed-rate lease immediately and it doesn't come with a contract with a 3rd-party provider, although I guess that depends on how much sunlight you have.
We got a house in San Diego near the bottom of the last market (2012) and I was a medical resident at the time with two school age children. The previous owner had installed electric everything (even had to get a larger trunk line run and breaker panel). So our electric bill was a little nuts, randomly hitting tier 3 pricing and landing $350+ electric bills. For a household with negligible marginal income, that was unpleasant. We had 0 capital to play with but switching to solar was a no brainer. Even the lease is cheaper than paying PG&E.
Would I do it that way again? Probably not. But I have more wiggle room now.
> hitting tier 3 pricing and landing $350+ electric bills
I just wanna chime in and add: PG&E got rid of the third tier (unsure when) and, in the Bay Area, we're looking at around $0.35-$0.40/kWh at the upper end of the rate schedule (plus an explosion in natural gas prices on the West Coast). $350+ electric bills are pretty much now the norm for anyone who wants to heat their house up much past 60°F.
My understanding is the leases are a challenge when you want to sell the house. New buyers would have to also agree to the lease's terms or you have to pay to break the lease and remove them.
