In California, Affordable Solar Power For The 99%

It wasn’t too long ago that rooftop solar panels were yet another expensive add-on for high end homes, but then again, it wasn’t too long ago that only the rich kids at your high school could afford pocket calculators, let alone mobile phones. Affordable solar power is starting to make its way down the income ladder, and a pair of statewide California solar programs show how that’s good news for utility customers and taxpayers, too.

Affordable Housing, Affordable Solar Power

One program is MASH, for Multifamily Affordable Solar Housing. That program qualifies eligible buildings for solar incentives. The basic aim of the program is to reduce electricity costs for low-income households, which can help ease the need to subsidize those expenses through utility rates or other public programs.

Included in the package is the goal of raising energy awareness among the occupants and property developers, too.

An even more interesting program is SASH, for Single-family Affordable Solar Homes, funded by multiple public and private sources. It is administered for California by the nonprofit group Grid Alternatives, which works one-on-one to engage low-income families in sustainable energy while promoting workforce development through the state’s booming solar industry.

One reason why rooftop solar panels are so expensive is the “soft costs” of installations including permitting, site design and grid connection. Under the SASH model, Grid Alternatives helps families through the entire process, including filing for rebates.

The SASH model also includes weatherization and energy efficiency upgrades to help the homeowner get the most bang out of the solar installation.

Grid Alternatives is a licensed solar installer as well as a nonprofit, which qualifies it to lead teams of solar industry trainees and other community members through the installation process.

That’s a win for households with lower energy bills and for underemployed workers with new experience that matches in-demand skills, while easing the need for public assistance.

Public Housing and Affordable Solar Power

SASH and MASH apply to privately owned low-income housing, and as it turns out there is a parallel movement afoot in government-owned housing as well.

Back in 2009, the San Francisco Housing Authority began installing solar panels on public housing. Solar projects in Chicago and Portland took it up to the next level by treating solar panels as one element in the design of healthier, more sustainable public housing.

Solar Power for the 99%

What could really blow the lid off the affordable rooftop solar market, though, is the skyrocketing popularity of power purchase agreements (PPAs). Under a PPA, the property owner pays only for the solar power, typically at a rate far below grid-supplied electricity.

Just last summer the Baltimore Sun reported on a company called Skyline Innovations, which installed solar thermal hot water systems under a PPA for the “cash-strapped” housing authority in Annapolis, Maryland. With no money required up front, the new system is saving about 30 percent on hot water heating.

Another opportunity has been demonstrated by the Department of Defense. Back in the 1990’s, DoD privatized its on-base housing, which now serves as the launching pad for solar PPA projects including $1 billion in rooftop solar projects by solar industry leader SolarCity. Called SolarStrong, that PPA project alone will total up to 300 megawatts and cover up to 120,000 military housing units.


As for households that don’t fall into low-income or military brackets, PPA opportunities are beginning to dovetail with the Obama Administration’s public-private initiative to lower the cost of rooftop solar installations.

It seems that it won’t be long before solar power is just as accessible and ubiquitous as, say, heating and air conditioning systems.

    PPAs are not at a rate that’s “far below grid-supplied electricity” even the PPA companies themselves admit that the reduction is only 10 to 15% below grid-supplied electricity rates. At today’s dramatically low prices, as little as $2.20 per watt for an installed solar system after incentives in California, a PPA makes absolutely no sense when compared to owning a solar system. And if you can’t afford to buy a solar system outright then why not get an FHA $0 down solar loan instead of a lease or PPA for a much greater return on investment. A $0 down solar loan requires a lower credit score (650) than the 700 requirement for a lease, you don’t need any equity in your home and best of all, you get to keep the 30% federal tax credit worth thousands of dollars and any applicable cash rebate and you’ll own the system which will make it far easier to sell your home when compared to having a lease or PPA attached to it.

      Hey, Ron.

      Sounds like you have a good bit of knowledge on this. Any interest in writing up a guest post? I’d like to get this info out to more people, but am afraid I’d make a mistake if I embarked on such a post, as this is certainly not my expertise.
