In this month’s Scientific American, writer Christopher Mims reports that a few enterprising businessmen have figured out a way around the daunting cost of installing solar panels on private homes: don’t buy the things—rent them.
It’s a brilliant idea. Here in Arizona, where a cloudy day is so rare as to elicit excited news reports from local television stations, the one thing that keeps people from covering their rooftops with silicon is the breathtaking expense. My electrician, who solarized his own home, said it would cost $30,000 to switch my house to solar power. It nets out to around $17,000 after various government rebates. But still…
That’s a lot of $300 summer power bills, and, as much as I’d dearly love to get off the grid, it’s way more than I can afford pay for a principle.
One of these outfits, SolarCity, proposes to install the panels on your home for nothing and lease you the equipment. The combination of a reduced power bill and the monthly lease payment represents a significant savings on your power company’s bill (or so it is claimed). And SolarCity points out that on average power companies have been jacking up the cost of electricity about 5 percent every year, so if you lock in your rate with a several-year-long lease agreement, your effective savings increase at 5 percent a year.
In a slightly different spin on this idea, SunRun, a company based in San Francisco and serving Northern California, charges around $1,000 up front and then sells you the power. Power costs, we are told, should be less than or about the same as your power company’s, but one way or the other, you get that comforting self-righteous feeling of powering your home with “clean” solar energy. It would be good to know what’s involved in the large-scale manufacture of solar panels and their ancillary equipment, but for the nonce we won’t look too hard at that issue.
Apparently a number of cities and states are also experimenting with ways to make retrofitting your home affordable, and many will provide rebates for residents who install various kinds of energy-efficient devices. Mims reports that Berkeley and Boulder will lend homeowners enough to pay for solar panels and installation, allowing them to repay the loan over 20 years as part of their property tax bill. There’s no sign of these programs at either city’s site, and so it’s impossible to tell whether such programs, if they exist at all, would save you anything month to month.
At this time, the cost of rooftop solar still exceeds the cost of buying power from a local utility. For me, that’s the bottom line: my summer bills are already way more than I can afford, and they never will go down. I don’t like leasing, which resonates of debt payment. And I’m certainly not going to lock myself into another $30,000 worth of debt slavery to install my own system. But I might put those compunctions aside for a no-money-down arrangement that would guarantee lower power bills than what I pay now.
Unclear what happens if you sell your house while you’re in the middle of a lease with an outfit like SolarCity. It would not be good if you had to pay the whole cost of the solar array out of the proceeds of the sale.To recover it, you’d have to jack up the sale price about 30 grand—good luck with that, anytime in the foreseeable future! Since yours would be the name on the lease, transferring the monthly payments to the buyers would be problematic: if they default, you could end up having to pay for their power until the lease expires.
What’s your take on this? Would you lease a solar power system from a private company?
