GAF Energy, a manufacturer of low-profile, roof-integrated solar solutions in North America, completed its largest residential solar roofing system. The more than 31 kW system was installed by GAF Energy partner Anbe Roofing.

The system was installed on a private home in Portola Valley, California and will produce 50,455 kWh of clean energy annually and save the homeowner an estimated $271,484 in electricity costs during the expected 25-year system lifetime.
“Solar roofs are the future and we’re proud to partner with Anbe Roofing to make that future reality,” said Keally DeWitt, vice president of marketing and public policy for GAF Energy. “Anbe demonstrated their expertise on this project, providing the customer with a durable, reliable, and innovative roof-integrated solar solution that will save the customer significant money. We look forward to our continued work with local roofing partners, like Anbe, across the country.”
The GAF Energy solar system combines is designed to be a low-profile alternative to standard rack-mounted solar panels — which are typically drilled through the roof’s shingles. GAF Energy solar integrates directly with the roofing system and requires no penetration of the roofing membrane. The system uses high-efficiency modules, a black perimeter shield and provides a matching color profile for certain rooftops.
“Typically, installing a new roof this size would require significant additional technical and labor support for completion — not to mention the extra planning and hours needed to add on a solar system atop the new roof,” said Joseph Andrews of Anbe Roofing. “Thanks to the streamlined design and build of the GAF Energy solar roof kit, this install was fast and easy for our team. It snaps together like a simple puzzle and looks amazing. You would never know we installed the largest GAF Energy system to date given how quick and seamless the process was.”

Almost anywhere in California one is serviced by an IOU electric utility. The three major utilities in California have some kind of block tiered rate electricity program that can go from $0.16/kWh stepping up to $0.31/kWh and in some cases TPU rate spiking of $0.47/kWh. One affiliate of the CPUC published a white paper saying that somewhere between 2025 and 2030 utilities PG&E and SCE will be on ‘average’ $0.30/kWh to $0.35/kWh electricity rates. SDG&E will be on average $0.47/kWh.
Well TESLA has the claims in their solar roof tile product, but complaints of waiting times for system installation and recently apparently an almost doubling of system cost installed has unhappy customers. Now GAF energy has a product with their own BIPV solution. Oh, yeah, what I could do with a 31kWp array.
