Guasti Solar reviews

This homeowner hired Joe and Beverly Guasti to design and install a 7 kW solar system on their house. They ended up with an array that has been in operation since 2009 and generates all the electricity the household uses each year. The Guastis stayed on top of changing regulations, rebates and laws throughout the process, and Beverly handled every bit of paperwork herself. The system has required no maintenance since it was installed, so the most striking detail is how the couple combined hands-on installation with full administrative follow-through to deliver a long-running, maintenance-free setup.

LMR hired Guasti Construction to fit a 5.7 kW solar system on their home more than ten years ago and ended up with a setup that’s still backed by the company. Guasti first examined the household’s yearly electricity use, then designed the array to match that profile, handled permits and paperwork, and stayed on-site for the final inspection. Years later a Fronius inverter developed a minor fault; Guasti troubleshot and repaired it under warranty without fuss. Throughout the relationship staff remained courteous and professional. The detail that stands out is the long-term follow-through — the crew didn’t disappear after install but returned to make things right when the inverter needed attention.

Anthony spent a year shopping for a solar solution for his off-grid home in the Los Angeles–San Bernardino–Riverside area and discovered something striking: almost every installer he approached refused off-grid projects. Two companies even steered him back to Guasti Solar, so after a year of searching he returned and hired them. From the first site walk, Joe mapped out the system and recommended components, Beverly managed the transaction, and installers Anthony Guasti and Luke Guasti carried out the install, commissioning, and the county coordination needed to pass inspection. When he requested two changes — adding a controller and swapping a dead battery — the Guasti team rolled with the updates and completed them without delay. They showed up on time, stayed professional through permitting and the turn‑up, and delivered a working off‑grid system; what stuck with him was that they did exactly what they promised and handled the county inspection and on‑site surprises so he could stop worrying about living off‑grid.

Carl hired Joe about eight years ago to install a windmill, and the installation turned out excellent. He still calls the same family team back for maintenance as needed. The thing that sets them apart is how they treat customers like friends—warm, familiar service—and they even host annual Christmas parties that keep the connection alive. After nearly a decade of service and upkeep, he appreciates both the quality of the work and the personal touch they bring.

Mike M. chose Guasti, a small family-owned business, to install solar on his home. He ended up with a wonderful installation and felt strongly enough about the team's work to highly recommend Guasti. The memorable detail: a hands-on, family-run crew that handled the whole job.

Layne Mckee realized they’d been running without a working solar system for months only after a huge Edison bill arrived. One phone call to Guasti Solar on Monday turned into a next-day fix — the crew came out and had everything repaired by Tuesday. They found the team easy to work with and efficient, and that quick turnaround changed what could have been an ongoing headache into a single, fast resolution. The detail that sticks: a single call delivered a same-week repair that erased the unexpected utility bill.

Jeff Thomas picked the company’s Bergey Wingpower generator for his home fourteen years ago. He relied on steady, hands-on product support through the years, and the unit still runs strong — driving his electric bill down to almost nothing. The memorable detail: a Bergey installed over a decade ago that keeps performing and keeps energy costs minimal.

John Cincotta hired the Guasti family to put solar on his home and was pleasantly surprised by how smoothly everything went. He found the crew — Anthony, Luke and Lisa — punctual and respectful, finishing the job on the timeline they promised and leaving the property clean. They kept him updated through the inspection and the utility turn-up, which Edison approved in only a couple of weeks — a turnaround that genuinely surprised him. The system went live quickly, now providing safe power and lowering his energy costs. He and his wife Bette appreciated the team's patience, honesty and hard work, with the fast interconnection and thorough cleanup standing out as the most memorable parts of the experience.

Annette Robinson hired the Guasti family to install two Bergey wind generators on her property. She found the crew professional and reliably on schedule, and their customer service made the process straightforward and low-stress. The project concluded with both Bergey units installed and the family-run team's professionalism as the most memorable aspect of the experience.
