#13 of 1,089 scored in California by Solar.com Installer Score

How does Powerfull Solar compare where you live? Rankings are local; an installer that leads one city can trail in the next. See how they rank in your city →

Why this differs from star ratings: most five-star reviews say “great company” and stop, and star averages reward that. These category scores only count reviews with concrete evidence, weighted by recency and the reviewer’s track record. A company can hold a strong star average while specific categories score lower; that gap is usually where the real story is. Categories with more complaints than praise are the questions worth asking any bidder, not necessarily dealbreakers.

Where Powerfull Solar builds

County-by-county activity from CPUC records through May 2026.

What this data covers: *Counts on this page, including the totals up top, come from investor-owned-utility interconnection records (SCE, SDG&E, PG&E). Work in municipal-utility territory, such as LADWP or city utilities, and outside California does not appear here, so this company's true totals are higher than shown. Unlike the county rankings, this profile also shows counties below the 250-install ranking floor.

Powerfull Solar reviews: what customers say

An independent synthesis of published customer feedback across Google and Yelp, updated September 23, 2026. Green marks praise, amber mixed experiences, red complaints.

Sales & proposal integrity

Sales Integrity7.1/10

Reviewers generally describe the sales and proposal process as clear, helpful, and easy to navigate. Praise centers on answered questions, straightforward expectations, and support with paperwork and financing; there is a small amount of pushy-sales feedback, but it appears rare in the review set.Solar.com's composite of published customer feedback, not a customer quote

Clear and helpful guidance. Reviewers often say the team took time to answer questions and make the process feel less overwhelming, especially around the paperwork and early planning steps. Representative review excerpt: "Everyone was easy to work with, answered all my questions, and made the whole process feel a lot less overwhelming."

Helpful with paperwork and financing. Several reviewers report that the company was helpful in navigating the financial and paperwork side of the process and that expectations were explained clearly. Representative review excerpt: "They were REALLY helpful when it came to navigating the financial + paperwork side of things."

Rare sales-pressure complaint. One reviewer describes the sales approach as pushy and overbearing, which stands out as an isolated complaint against an otherwise positive pattern. Representative review excerpt: "I found them to be pushy and overbearing with their sales tactics."

Price & financing transparency

Price Transparency6.9/10

Feedback on pricing and financing is mostly positive, with reviewers describing fair pricing, reasonable estimates, and helpful handling of financial paperwork. Reviewers also mention savings and return on investment, while incentive timing appears in the broader process comments rather than as a major complaint theme.Solar.com's composite of published customer feedback, not a customer quote

Fair pricing and reasonable estimates. Reviewers describe a recurring pattern in this area. Representative review excerpt: "I was impressed by the fair pricing and high-quality solar panels provided by Powerfull Solar, Inc."

Savings and financing clarity. Some reviewers report that the company was helpful with financial details and that the system delivered savings they were expecting from the project. Representative review excerpt: "They were REALLY helpful when it came to navigating the financial + paperwork side of things."

Value described positively. Customers commonly frame the purchase as a good value, citing money savings and strong perceived return from the system. Representative review excerpt: "The savings I'm enjoying from my reduced energy bills are a testament to the excellent return on investment provided by this solar company."

Communication & coordination

Communication8.0/10

Communication is a major strength in the review set. Reviewers repeatedly describe the team as responsive, friendly, and organized, with clear handoffs and frequent updates through the project. A small number of reviews mention that post-install updates could have been better.Solar.com's composite of published customer feedback, not a customer quote

Responsive and easy to reach. Reviewers commonly say the team responded quickly to questions and was easy to communicate with throughout the process. Representative review excerpt: "The team was awesome to work with super friendly, easy to talk to, and always quick to respond if I had questions."

Kept customers informed. Many reviewers report being kept informed at each step and say the project felt easier because of the company’s coordination. Representative review excerpt: "They made the whole solar process much easier than we expected and kept us informed every step of the way."

Post-install updates could improve. One reviewer wished for more updates after installation, suggesting a limited post-install communication gap in an otherwise strong category. Representative review excerpt: "The only thing I wish they did better is to give more updates after the install."

Timeline reliability

Timeline Reliability7.3/10

Timeline feedback is mostly positive, with reviewers describing on-time installs, smooth scheduling, and helpful handling of permits, inspections, and utility approval steps. A few reviews note delays or reduced follow-up during activation stages, so the category is solid but not flawless.Solar.com's composite of published customer feedback, not a customer quote

On-time and well-coordinated installs. Reviewers often say the crew showed up on time and that scheduling was handled smoothly around their needs. Representative review excerpt: "The crew showed up on time, kept the work area clean, and took the time to answer all of our questions throughout the process."

Handled permitting and approval steps. Some reviewers describe helpful support through city, utility, and inspection approvals, even when those steps moved slowly. Representative review excerpt: "Through out the solar construction, and after that, when we had to go through slow city and DWP approval, they were very helpful in every way."

Limited follow-up after install. One reviewer reported hearing from the company only right after install and again when PTO was granted, pointing to a post-install communication gap during the timeline process. Representative review excerpt: "In that time I only heard from Powerfull once right after install, and when PTO was given."

Workmanship & site care

Workmanship8.0/10

Reviewers consistently praise the quality of the installation work and the professionalism of the crews. Comments commonly mention clean work areas, punctual crews, and completed jobs that matched what was described beforehand. Complaints are not a meaningful pattern in this category.Solar.com's composite of published customer feedback, not a customer quote

Professional crew behavior. Reviewers frequently describe the installation crews as friendly, professional, and willing to answer questions during the job. Representative review excerpt: "Luis, Alejandro, and the rest of the installation crew were incredibly friendly, professional, and took the time to address every question I had about how the system works."

Clean and solid workmanship. Customers often report that the work was done cleanly and professionally, with solid quality and strong attention to detail. Representative review excerpt: "The quality of the work was solid, and everything was done clean and professionally."

Followed through as promised. Several reviewers say the installation matched the original description and was completed with care and cleanliness throughout the project. Representative review excerpt: "They were on time, And followed through with What they had described would happen and when period and they did a perfect job."

Long-term support & performance

Long-Term Support7.1/10

Post-install feedback is favorable overall, with reviewers saying their systems are performing well and that they are seeing expected savings or benefits. The available review set is lighter on warranty and long-term service detail than on installation feedback, but the existing comments remain positive and show few concerns.Solar.com's composite of published customer feedback, not a customer quote

Systems performing well. Reviewers report that their systems are working well after installation and that they are already seeing benefits or savings. Representative review excerpt: "My system is performing great, and I’m already seeing savings on my electric bill."

No-issue performance reports. Some customers say the system has been working great so far with no issues, which supports a positive post-install picture. Representative review excerpt: "My system’s been working great so far with no issues."

Benefits after install. Reviewers also mention that the new solar system is delivering the expected benefits after the project is complete. Representative review excerpt: "I’m already seeing the benefits of my new solar system, and the quality of the workmanship exceeded my expectations."

Bottom line: POWERFULL SOLAR’s review profile is strongest in communication, workmanship, and general project coordination, with most reviewers describing responsive support and clean installations. Pricing and sales feedback is also mostly positive, while timeline and post-install support are solid but show a few isolated watch-outs around updates and approval-stage follow-up.

Important context: this chart shows investor-owned-utility records only. Companies that shift work toward municipal-utility territory (LADWP and city power departments) or other states will show declining bars here even while building steadily elsewhere, and 2025-26 records also lag real installation dates. Treat this as a partial window, not the company's full trajectory.

How we built this data

Methodology: Counts are residential PV interconnections in investor-owned-utility territory (PG&E, SCE, SDG&E) per CPUC Rule 21 public records through May 2026. Postal and name variants are merged. Municipal utility territory such as LADWP, Glendale, Pasadena, Burbank, Anaheim, and Riverside Public Utilities is not included in those CPUC counts. Counts show recorded installations, not quality ratings. Reported costs are self-reported on owned-system interconnections. No installer can pay for placement.

Who we are: Solar.com is a solar marketplace — we connect homeowners with installers and earn a fee when projects move forward. These rankings and scores are computed from public installation records and published customer reviews. No installer can pay for placement, and no installer — including those we work with — can pay to change a score.
