Solar Power Integrator reviews

Drew hired Solar Power Integrator to install a residential solar system that came online on January 4, 2023. He discovered the panels reliably lowered and stabilized his electric bill within the first year, and the system has run trouble-free — he’s only cleaned the array twice with a hose. He worked with a capable, genuinely caring crew throughout the process, and the steady savings have him planning to buy an electric car next so he can eliminate his gas bill.

Robert worked with Gianluca to install solar panels on his home three years ago, and he’s still very happy with the outcome. Gianluca guided him through the process so it felt straightforward, and the reduction in his electric bills proved impressive. Even outside professionals took notice: the roofing contractor and a windstorm inspector both complimented the quality of the installation. He now tells friends about SPI Go Green because of the ongoing savings and the standout workmanship that professionals praised.

After a decade of on-and-off research, Grady discovered Solar Power Integrator and connected with Gianluca (Luca); a single phone call and an in-person visit convinced him and his wife they’d finally found the right team. Luca walked them through the system in plain, understandable terms, and the installation backed that clarity with meticulous workmanship. Every roof bracket received two torque-wrench checks, and the crew installed the panels using only hand tools to avoid over-tightening and potential damage. The system has been running just over a year: the first couple months cut their energy bill roughly in half, and after switching to a more solar-friendly provider they spent only $97.37 on electricity over the last 11 months. Based on their five-year pre-solar average, they now pocket about $150 a month after the loan payment. What stayed with him most was the attention to detail during install — the double torque-wrench checks and hand-tool panel work — and the strikingly low $97.37 bill over nearly a year.

Max had the company out a year ago to fix a generator, so when his rooftop solar array stopped producing yesterday he reached back out. The crew dispatched a technician who climbed onto the roof, hustled through a fast, hard-working inspection and repairs, and got the system back online the same day. Beyond the quick fix, they handled the follow-up by arranging for the affected panels to be sent off under warranty. He found their response prompt and their pricing reasonable, and left with his panels restored and the warranty claim already in motion — the practical detail that stood out was that the team didn’t just repair the problem, they took care of the paperwork too.

Florence T had Gianluca, the owner, install solar panels on her house six years ago. He continued to perform routine checks and, earlier this year, discovered one microinverter had stopped working — it was still under warranty, so he ordered and installed a replacement at no cost, fixing an issue she hadn’t even noticed. Every visit from him and his crew has been punctual, professional, and remarkably quiet, and the original installation has held up well. What stuck with her most was the long-term care: proactive inspections and warranty handling that keep the system running years after the initial install.

Samantha had been living with a residential solar array sidelined for two months while her installer, Sunnova, gave her the runaround. She reached out to SPI and found Cathy, who walked her through practical steps, promised help, and — despite a booked schedule — managed to squeeze her in as soon as possible. They chatted warmly during the call; Cathy’s persistence and clear instructions stood out more than anything. When SPI’s technician arrived, he immediately identified the problem, moved efficiently through the repairs, and confirmed the panels were “100% up and running” before leaving. After weeks of stalled service from her original company, Samantha walked away with a working system and the specific memory that a single responsive contact—Cathy—made the difference in getting the job completed.

John Pope has relied on Gianluca Ferrario for years for solar, generator and electrical work on his properties. He discovered that Gianluca brings a rare mix of building-science expertise, current technology know-how and true mastery as an electrician. Across multiple projects, he consistently walked away impressed by Gianluca’s depth of knowledge and practical capability. The detail that stuck with him: Gianluca doesn’t just design or recommend systems—he has the wiring and hands-on skill to execute complex installs reliably.

Tom G. hired Solar Power to put a 12 kW solar array and a 24 kW Generac generator on his property near Goliad. He brought a sharp eye to the job—retired after decades as a contractor, architect, and home builder—and had struggled to find reliable contractors in the area before this. He discovered Lucas Ferreira, the owner and a licensed Master electrician, and trusted him to lead the project. Lucas’s crew worked methodically and professionally, focused on doing the job right, and their bid came in well below other estimates. Tom appreciated that Lucas did not require any money up front. The installation finished smoothly, and after several weeks the system has run flawlessly. The detail that sticks with him: a licensed master electrician who delivered lower pricing, no up-front payment, and a clean, problem-free installation.

Shaun reached out for a quote and was surprised when Luca, the owner, delivered a same-day estimate — complete with imagery and mapped plans — within about two hours of the phone call. He watched the project move fast after that: from quote to roof install in under a month, with an installation team that left the job feeling high quality and well executed. He discovered SPI leans on word of mouth rather than big marketing, and that showed in how focused the crew was on craftsmanship and post-install service. Having explored more than four quotes and having no prior connection to the company, he judged SPI to offer strong value: a solid warranty, clear plans, responsive servicing, and workmanship that met or exceeded his expectations. What stuck with him most was the turnaround and clarity — the two‑hour visuals and mapped plan followed by a sub‑month install — a combination that made the choice straightforward for someone in Corpus Christi.
