We installed a solar system with batteries with Dura-Foam last year. The system is working fabulously – it went through a winter with several power outages, and we usually don’t even know we have an outage until PG&E informs us. What a relief. Dura-Foam’s owner Trevor Hill was responsive, open to new ideas & willing to work with new partners. We integrated a battery system from FranklinWH as well as a SPAN sub panel to maximize the use of the solar power we are producing. Dura-Foam worked with the FranklinWH rep Trevor Gould to design and install a robust system that is transparent, efficient and most of the time completely self-reliant. One glance now tells me how much I produce, what I use, and what I use it for. Franklin’s aGate & SPAN were just the combination for someone like me who really likes data. Trevor Hill was patient and willing to answer any questions during the installation, the plan set was comprehensive, the work his team did was excellent, and they met the occasional construction challenge with the willingness and expertise to make it right. Cooperation with FranklinWH was clearly excellent. And finally, Trevor Hill even put together a full package of cohesive documentation for the CPA to document everything for the tax credit. 5 stars all around for the entire team and the products that make up our wonderful system.

I had contacted Durafoam and talked to Trevor about some minor roof work earlier this year. He was very responsive and got that done quickly. We eventually had them resurface our 20+ year old foam roof in summer and they were able to fit us on short notice. Always cheerful, Ali was a pleasure to work with. He and his crew were hardworking, as well as meticulous, and took time to protect the fruit and vegetable plantings in my backyard. Anthony, who's in charge of ops, was here a couple times and helped us resolve some logistical issue on the project. We are very happy with the quality of the roof work. Ali's team was able to accommodate our schedule and completed the job just as house guests AND a heat wave were expected at the same time! Thanks to our newly resurfaced roof, our home, which has no AC, weathered several extended heat waves of 90-100+ F this summer comfortably. While foam roofs are not cheap, they sure make severely weather more bearable! I totally recommend Durafoam to anyone looking for a great foam roof contractor!

We recently needed a roof inspection on short notice for insurance purposes. Trevor from Dura Foam followed up quickly to our call. He helped us out, and gave us the documentation we needed to avoid a bad situation. We really appreciate their great response and workmanship!

Dura-Foam Roofing & Solar Center were really easy to work with! I would definitely recommend them to anyone with roofing issues. They responded to my inquiry and were able to get someone out to look at our roof quickly. I'll definitely reach out again in the future if we have any other issues that come up!

Dura-Foam Roofing & Solar Center did a fantastic job repairing our foam roof after it was damaged by an enormous fallen tree. Lusio, David, and Emiliano each performed different parts of the complicated job. They were all very professional and cordial. The work was performed efficiently, neatly and on schedule. And Isaac, the office staff person who coordinated our job, was a pleasure to work with. We couldn't have been happier. I highly recommend this company!

A Bay Area treasure. Look at the pictures and you will see the people that you will be working with. They pose like a family and that is exactly how it feels to work with them. 9 years and 6 months after my roof and solar project was installed, I had an issue with my solar generation. I called Dura-Foam and was surprised that they remembered me, my home and the installation. Anthony and Lusio came out and quickly identified the issue. Hard working and professional, they took the time to double-check everything and allay my concerns. They stand behind their work and did not charge me for the service call even though it has almost been 10 years since the install. If you have a roof (especially an Eichler) you need to give these folks a call. Honest, courteous and professional Dura-Foam is the right call for roofing and solar.

We were very satisfied with the service. We found the workers were very cordial and we appreciate it!

The Smarter, Safer, and More Reliable Battery Solution

When it comes to home battery storage, Qcells Q.HOME CORE, Tesla Powerwall 3, and FranklinWH are three of the top contenders. But not all batteries are created equal. If you’re looking for a powerful, scalable, and seamlessly integrated solution, Qcells Q.HOME CORE stands out as the superior choice.

Why are We qualified to serve you | Accreditations & Accolades

Why are We qualified to serve you | Accreditations & Accolades

Why Qcells Q.HOME CORE Outperforms Tesla Powerwall 3 and FranklinWH

1. Safer, Longer-Lasting Battery Technology

Qcells Q.HOME CORE and FranklinWH both use Lithium Iron Phosphate (LFP) batteries, known for their superior safety, longer lifespan, and lower fire risk compared to Tesla Powerwall 3’s Lithium-Ion (NMC) battery. LFP batteries degrade more slowly, ensuring consistent energy storage performance for years to come.

2. True Scalability – Expand as Your Energy Needs Grow

Unlike Tesla Powerwall 3, which has a fixed storage capacity per unit, Qcells Q.HOME CORE is fully modular and expandable, allowing homeowners to increase their battery capacity over time. FranklinWH also offers modular storage, but it lacks the seamless integration that Qcells provides with its solar panels and inverters.

3. Smarter Energy Management for Maximum Efficiency

Qcells Q.HOME CORE comes with Q.HOME ESS smart energy management, allowing you to track, monitor, and optimize your energy use in real-time. Tesla Powerwall 3 has its own app, but it’s designed primarily for Tesla solar systems, limiting flexibility. FranklinWH uses its aPower & aGate system for energy management, but it lacks the advanced integration Qcells offers with its complete solar ecosystem.

4. Reliable Backup Power You Can Trust

All three batteries provide automatic backup power during outages. However, Qcells Q.HOME CORE is engineered for seamless and efficient energy switchover, ensuring minimal disruption to your home’s power supply.

5. Industry-Leading Warranty & Long-Term Performance

Qcells Q.HOME CORE comes with an industry-leading warranty, guaranteeing long-term performance and reliability. Tesla Powerwall 3’s warranty is more limited, while FranklinWH’s warranty is strong but does not offer the same depth of integration and scalability as Qcells.

Why Qcells Q.HOME CORE is the Smartest Choice

Safer and more durable LFP battery technology than Tesla Powerwall 3.

Seamless integration with Qcells solar panels and inverters for a complete,

Industry-leading warranty for long-term reliability.

Real-time energy tracking and optimization with Q.HOME ESS.

Modular and expandable storage, unlike Tesla’s fixed capacity.

Power Your Home with the Best in Energy Storage

If you want a safer, smarter, and more adaptable battery solution, Qcells Q.HOME CORE is the clear winner. Don’t settle for a one-size-fits-all battery—choose a system that grows with your energy needs and maximizes your savings.

Dura-Foam customers consistently report dramatic improvements in comfort and energy savings after upgrading their roofs.
