Solar for All: Making Solar PV Accessible to Low-Income Families in the U.S.
Here at RMI we love seeing electricity generated by the sun. And while it’s great to see large homes owned by the likes of Woody Harrelson and Will Ferrell being solar-powered, rooftop solar should be accessible to people across the socio-economic spectrum of the U.S., not just the one percent. But putting solar on all of these different roofs is currently a serious challenge.
Even with lowered PV costs and the prevalence of third-party financing programs, solar is largely out of reach for many low-income families. Many are renters who do not own their homes, putting them at the mercy of their landlord. For those that do own their homes, few have enough tax liability to take full advantage of federal and state tax incentives for rooftop solar. That’s largely a moot point anyway, since even with incentives the steep upfront cost of rooftop solar in the U.S. still puts a PV system financially out of reach for low-income families. That’s where third-party leasing can come in, but many low-income families have low credit scores and most solar leasing companies require a credit score of at least 700. It’s one potential financial barrier after another.
Some more:
“Low-income families pay into the rebate pool like everyone else. Yet often, even with rebates, they can’t afford a solar home system,” Shirley Moore, program manager at Grid Alternatives, told RMI. Grid Alternatives, or simply Grid, as it is fondly called, is a nonprofit organization providing low- to no-cost PV systems to low-income families throughout California, Colorado, New York, New Jersey, and Connecticut. Homeowners who earn 80 percent or less of the median income and have a solar-appropriate roof qualify for a Grid Alternatives PV system. “We see people save an average of 50 to 75 percent off their electric bill. Money that can go towards paying their mortgage, putting food on the table, or saving for college,” said Moore.
Grid works with local partners to find qualifying families. The families do not have to put any money down, but do have to contribute 16 hours of sweat equity. They can work in the Grid office, help on the installation, or even cook lunch for the installation volunteers. They then pay $0.02 per kilowatt-hour for what their system produces. It’s a small price to pay for leasing the system, often adding up to only about $100 per year, but according to Chuck Watkins, executive director of Grid Alternatives–Colorado, “we want the homeowners highly engaged with their system and aware of their energy usage.”
A similar organization, Citizens Energy, provides free solar PV systems that reduce homeowners’ electricity costs by 40 to 50 percent in the Imperial Valley of California, an area with the highest unemployment rate in the country. With temperatures in the area climbing to 120 degrees Fahrenheit, homeowners can have a difficult time paying for the electricity to run their air conditioners. Citizens Energy uses 50 percent of its profits from its share of the Sunrise Powerlink high-voltage transmission line that brings renewable energy to the San Diego region to purchase, install, and maintain the systems. The homeowner signs a 20-year lease only after they receive a free energy audit and weatherization services. One of the 200 homeowners to receive the free PV system saw her monthly summer electricity bill go from $350 to $85.
This all sounds nice - classical liberalism at work but I got two questions:
- Is this the most efficient way to cut their energy costs (hint: NO!) and
- Who pays for this (hint: the rest of us - another example taxation without representation.)
Problem is that Solar is not a baseload energy source. Your total energy production is at best, 1,000 watts per square yard. This is high noon, cloudless sky, dry air and the panels optimally pointing toward the sun. All the rest of the time, you are getting a few hundred watts per sq. yd. If you need to live off-grid then fine - solar is your best option. If we put this money into nuclear power, we could slash everyone's utility bill and our economy would come roaring back to life.
The cost of these programs are being paid for by the taxpayers - this is taxation without representation. Where did I vote for this program?

Dave - re solar phoolishness: don't forget to correct the solar flux of 1 Kw/square meter for the proportion that's not in the infrared. Only about 7% is available in the visible spectrum for photocells.
