Who Are Google’s Project Sunroof Partners?

As we wrote months ago when it launched, Google has a free online service that uses its mapping information and partner offers from solar installers to provide fast estimates of how much a homeowner might save by investing in a solar power system. Dubbed “Project Sunroof,” it also provides information on things like the number of square feet available for solar panels on your roof based on 3D modeling, the number of hours of usable sunlight per year based on weather pattern analysis, net savings over 20 years, an average monthly electric bill, and recommended solar power system size.
Currently, the Google service can provide information in the Boston area, the San Francisco area, Fresno, Napa, Sacramento, and Long Island. Partners for the project were not initially listed in the press releases, blog posts, and media coverage, so we decided to dig in and see who they are. Seeing offers from SunPower, American Solar Direct, Pick My Solar, Sungevity, SunEdison, NRG Home Solar, we can see that these are the highly regarded solar companies Google decided to partner with (in the initial San Francisco area where I live, at least).
Providing this information for free is a great service, because it brings rapid clarity to those who are curious or interested but don’t know how to gather basic information about what kind of solar power system might work with their home and how much they could save by going solar.
For example, do you know the square footage of your roof? Everyone knows how much they pay for their electricity each month, but you also know what size solar power system would cover your electricity usage?
NREL has a similar online tool, but it wants more technical information, like the azimuth of the roof, DC system size, tilt in degrees, average cost of electricity purchased from the utility in $/kWh, and so forth. The problem is that many people may have never heard of some of these terms and therefore might not be able to use the tool.
The Google tool is much simpler and easier to use, if you aren’t aware of some of the technical details.
Cost of Solar (part of our company) is similar and we think still worth using, since it may connect you with small-scale but competitive solar companies in your local area, but it again asks for technicalities like the square footage of your home, your heat source, roof shading, and roof type (asphalt shingle vs ceramic vs clay tile vs wood shingle vs metal vs something else). What we typically recommend is trying to get as many solar quotes as possible, using Google’s Project Sunroof, Cost of Solar, EnergySage, and others. The more solar price and savings quotes you can check out, the more equipped you are to evaluate each of them and find the best deal.
