With 30+ Years Of Experience, No One Knows Solar Like Simmitri

Hillsborough is full of beautiful homes, plant life, and people. While not every residence is as grand as, say, the Carolands estate, homeowners love their slice of heaven in one of the most affluent U.S. cities.

And when it comes to quality-driven home improvement products and services, Hillsborough home/business owners alike understand and appreciate the value we bring to the table — even if it costs a little extra.

Here at Simmitri, we’ve been curating our home improvement services to meet the needs of every individual, no matter how big or small of a project, for 30+ years. We believe you don’t have to be a millionaire to be treated like one, especially when working for a cleaner tomorrow.

“Simmitri is an excellent solar company. Everyone was readily available and responsive to my questions. They started the project on time. The installation supervisor was a perfectionist and explained everything clearly. I interacted with at least 7 Simmitri personnel, and all were pleasant and successful interactions. The price was right. I recommend Simmitri for solar installation without hesitation.”

Our Services For Hillsborough Home & Business Owners

We’re focused on clean energy and protecting our earth and have built our company around these movements. Each of the services we offer Hillsborough residents is ultimately geared toward optimizing energy usage on a long-term scale and educating folks on the best ways to ensure our environment is thriving for future generations.

Simmitri is proud to offer the following services for Hillsborough, CA, and the surrounding areas. Head to our Service Areas page to see if you’re in our wheelhouse.

Residential & Commercial Solar

Hillsborough joins many other California cities that couldn’t be in a better location to utilize solar energy. It’s sunny almost every day, the UV skyrockets in the summer months and most homes have more than enough roof space to harness solar panels. The perfect trifecta for making the switch to solar!

Solar energy is undeniably one of the cleanest ways to power your home or business , and now it’s easier than ever to incorporate our state-of-the-art technology. And with many affordable financing options available for qualifying Hillsborough customers, we have a solar plan to fit any budget.

Residential & Commercial Roofing

Many home and business owners think of their roofs only when problems occur. Leaks, missing shingles, mold, and mildew — the signs of needing a roof replacement are endless. But if you consider adding solar to your home or business, your roof may need replacing sooner than expected.

Most roofs aren’t initially designed with the sole intention of installing solar panels at a later date, whereas our GAF roofing systems are designed precisely for that. And when it comes time for the installation, our GAF Master Elite Roofer status ensures you can sleep easy knowing every tiny detail is being attended to.

“Simmitri was professional, responsive, and did a high-quality job. I shopped around before deciding which company to use for our solar panel job, and this company blew away the others.
