Powerfull Solar reviews

The Verdict
Powerfull Solar installs without cutting corners on the equipment. One homeowner who compared quotes from big-box installers and local shops found Powerfull was using current-generation Enphase microinverters while competitors quietly spec'd older, cheaper models, yet Powerfull's price still came in among the lowest. Another customer had a representative return to the house multiple times after installation just to walk through the monitoring apps until everything made sense. We found 53 reviews praising workmanship with zero complaints, and 72 mentions of smooth project management. Eitai, the project manager, handles every job personally from quote to final commissioning. One customer went to Disneyland during the install and came home to a finished 7.2 kW system; another dealt with LADWP inventing electrical code on the fly, and Eitai cycled through utility reps until he found one who would approve the interconnection. (Yes, a utility employee admitted to making up code.) The install crews finish most jobs in under a day, leave sites clean, and don't upsell you on add-ons you don't need.
If you want the sales rep to also be the project manager who shows up on Saturdays to configure your monitoring system, Powerfull Solar is the rare installer where that actually happens.
Reviews That Shaped Our Verdict
Rose M. chose Powerfull Solar for a project on an older home with aging infrastructure and quickly discovered the job would have many moving parts. Eitai and the team navigated those complications, taking time at each stage to explain what needed to happen and why, so she always knew the plan. They also handled the paperwork efficiently, promptly filing for permits and coordinating with the city to keep the timeline moving. The memorable part of her experience was their combination of clear, patient communication and hands-on work with local officials — she didn’t have to worry about the permit process herself.
Marcus hired Powerfull Solar Inc. to outfit his San Marino home with a 15 kW solar array and four Enphase 5P batteries, and he walked away genuinely impressed. The crew handled the install smoothly, bringing clear expertise and attention to detail so everything was set with precision. What set the job apart was the follow-up: a company representative kept coming back after the hardware was live to configure the monitoring apps and personally show him how to operate the system. That hands-on coaching left him comfortable with the controls and confident the system is performing exactly as promised. The thing he remembers most isn't just the equipment, but those repeated technician visits that turned a high-end install into a system he actually knows how to use.
Jesse W. started out comparing a stack of bids — everything from big-box installers to small local crews — and discovered right away that Eitai stood out because he not only presented the proposal but promised to manage the project and be on-site for the install. He liked that Eitai’s family owns the parent company, Powerfull Electric, which made it clear Eitai had skin in the game. Pricing landed competitively, and Eitai even adjusted numbers when Jesse showed similar offers from competitors. Having dug deep into solar technology, Jesse appreciated that the equipment lineup avoided cheap compromises: the system ended up as a 7.2 kwh setup (18 QCell 400W panels with IQ8M microinverters), matching top-tier components he had been looking for while still coming in near the lower end of his quotes. Eitai didn’t cut corners on hardware, and that gave Jesse confidence the array would last for decades. Eitai handled scheduling and communication smoothly, working around Jesse’s calendar from inspection through install. The crew completed the entire roof work in under a day, and Jesse received progress photos while his family stood in line at Disneyland — a quirky detail that kept the “

What You Can Expect
Tommy Bareket teamed up with the company's electrical arm, Powerfull Electric, and over the past few years he experienced steady, hands-on service where the crew kept him informed at every stage. He valued the clear communication and the sense that the installer would handle issues from permit through commissioning. The system ended up producing surplus energy, cutting his bills dramatically and shifting him from renting power from SCE to effectively owning his own electricity. What stood out most was the combination of reliable service and measurable savings — surplus production and lower bills became the concrete payoff.
Desobry needed solar and battery work while his house was undergoing a major remodel, and Powerful Solar, led by Eitai, stepped in where others had declined. They coordinated the install around the construction schedule, kept appointments, and worked with the kind of precision and neatness that made the whole process feel stress-free. The crew left a clean, professional installation that clearly showed attention to detail, and Eitai stayed responsive throughout—answering questions quickly and following up with well-researched answers when needed. Product choices and technical support also impressed him: high-quality equipment paired with knowledgeable, helpful follow-through. He gave them five stars, and what stuck with him most was their willingness to handle a tricky timing challenge plus the spotless, detail-focused finish.
Duong hired Solar Power to put a home solar system in place and connected with Etai, who guided the project from day one and stayed available for every question or concern. They watched his team handle the installation with consistent courtesy and professionalism. The array has been performing flawlessly, noticeably cutting their electric bills, and it came at what they found to be the most competitive price in their search. The detail that stuck with them was the combination of a single, responsive point of contact and a system that immediately delivered real savings.
