How does Gr8 Energy 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 Gr8 Energy 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.

Gr8 Energy reviews: what customers say

An independent synthesis of published customer feedback across Google and Yelp, updated September 28, 2026. Green marks praise, amber mixed experiences, red complaints.

Sales & proposal integrity

Sales Integrity7.8/10

Reviewers mostly describe the sales process as clear, responsive, and helpful. Many say questions were answered quickly, options were explained plainly, and paperwork expectations were handled smoothly; only a small number of comments raise concerns about sales follow-through or savings expectations.Solar.com's composite of published customer feedback, not a customer quote

Clear explanations. Reviewers say the team explained panels, inverters, warranties, and system options in a way that felt easy to understand and not overly technical. Representative review excerpt: "I had several very technical questions about specific panels, inverters and warranties, he explained everything to me in a way that was very concise, unbiased and understandable."

Responsive proposal support. Several reviewers report quick answers to questions and helpful guidance through the decision process and paperwork steps. Representative review excerpt: "He was so helpful and was able to answer all my questions super fast."

Expectation gap watch-out. A small number of reviewers describe a gap between projected and actual bill savings, so some customers suggest carefully reviewing proposal assumptions and contract expectations. Representative review excerpt: "I was told my energy bill would completely disappear, but I am still seeing about $10-$20 a month in electricity costs, plus the cost of the loan payments."

Price & financing transparency

Price Transparency6.9/10

Feedback on pricing and financing is generally favorable, with reviewers often saying quotes felt fair and financing was explained or arranged without much friction. Still, some comments describe payment or cost concerns, including delayed refund-related activity and disappointment with overall cost and expected savings.Solar.com's composite of published customer feedback, not a customer quote

Fair pricing feedback. Reviewers say the price felt reasonable, and some describe the quote as within the range they expected after comparing financing and system options. Representative review excerpt: "I went with this company because I felt comfortable talking with Ross and the price I was given was fair and within the range of the others."

Financing help. Several reviewers report that financing was handled as part of the process and that the team helped them move forward with the project. Representative review excerpt: "He met with us within 24 hours of contact, gave us quotes for different options, and helped us get financing."

Cost concern watch-out. A minority of reviewers describe concerns about overall cost, pending payment issues, or savings that did not offset what they expected. Representative review excerpt: "This has caused the system to be a huge time and money sink without generating nearly enough in terms of energy bills to offset the cost."

Communication & coordination

Communication6.8/10

Communication and coordination receive mixed-to-positive feedback overall. Many reviewers praise fast answers, polite crews, and smooth handoffs, but this category also has a meaningful share of complaints about difficulty getting callbacks, updates, or post-install help.Solar.com's composite of published customer feedback, not a customer quote

Smooth handoffs. Reviewers say the project often moved smoothly through paperwork, scheduling, and crew handoff, with some noting clear email and text communication.

Helpful day-to-day contact. Several reviewers report that questions were answered quickly and that the team stayed in touch during planning or installation. Representative review excerpt: "Ross took the time to explain various options and we went back and forth via emails and texts and then we made a decision on a system that met all..."

Callback frustration. A noticeable group of reviewers say they had trouble getting responses after reaching out for service or updates, especially when they needed help after the install. Representative review excerpt: "Just like many others, I have called and emailed for service and I can not receive a call back."

Timeline reliability

Timeline Reliability7.5/10

Timeline feedback is mostly positive, with many reviewers saying permitting, scheduling, and activation moved efficiently. The main complaints center on delays tied to inspections, utility steps, or missed follow-up when customers were waiting for an update.Solar.com's composite of published customer feedback, not a customer quote

Fast scheduling and activation. Reviewers often say paperwork, permits, or activation steps were handled quickly and that the crew arrived as scheduled to keep the project moving. Representative review excerpt: "Ross and his company took care of the paperwork for Net metering application and the installation of the RMA and the permit for the solar system."

On-time install experience. Several reviewers report that installation happened on time or finished quickly, with work completed in one or two visits. Representative review excerpt: "The installers were on time, cautious, and did a great job making sure we understood what they were doing."

Delay watch-out. A smaller set of reviewers describe delays caused by inspections or by waiting for project updates, so schedule timing may still vary by job. Representative review excerpt: "Within a week, our project went through inspection and some hassles with our area's inspector caused a delay."

Workmanship & site care

Workmanship8.4/10

Workmanship and site care are among the strongest parts of the review set. Reviewers frequently describe professional crews, careful installation, good cleanup, and projects that were finished without major issues; only a few comments mention site or repair-related concerns.Solar.com's composite of published customer feedback, not a customer quote

Professional crews. Reviewers say the installers were polite, respectful, and careful while working on the home. Representative review excerpt: "Installation and detail to work went seamlessly and the work crew were polite, respectful, and ensured that I understood how to use the Enphase App to manage my battery system."

Cleanup and finish. Several comments mention that the crew cleaned up after themselves, put everything back in place, and left the site looking orderly. Representative review excerpt: "They cleaned up after themselves and again, the professionalism was there!"

Repair-related concern. A small number of reviewers describe problems tied to later panel removal or roof access, which suggests follow-up work can be more complicated than the initial install. Representative review excerpt: "We have been trying to work with Ross for a month to have his company remove a few panels so the roofer can find the source of the roof leak."

Long-term support & performance

Long-Term Support7.2/10

Long-term support and performance are viewed more positively than negatively, but this is one of the more uneven categories. Reviewers praise helpful follow-up on some jobs, while others report slow responses, unresolved monitoring or production issues, and trouble getting service after the system was turned on.Solar.com's composite of published customer feedback, not a customer quote

Helpful post-install follow-up. Some reviewers say the team stayed in touch after installation and helped make sure they understood how to use monitoring tools and battery features. Representative review excerpt: "Installation and detail to work went seamlessly and the work crew were polite, respectful, and ensured that I understood how to use the Enphase App to manage my battery system."

Support that stayed engaged. A few reviewers describe good follow-up communication after the project and say they felt supported after the sale. Representative review excerpt: "Grace was a joy to work with and stayed in touch to make sure we were happy customers."

Service gaps watch-out. Several reviewers report difficulty getting help when the system needed service or when production and monitoring issues appeared later. Representative review excerpt: "Then after a few months of the system mostly working, it has stopped responding and generating, and I haven't been able to reach anyone at GR8 energy for over a..."

Bottom line: GR8 ENERGY’s review profile is strongest on workmanship, sales clarity, and timeline execution, while price transparency and especially communication after install are more uneven. The overall Solar.com installer score of 8.1/10 reflects that mix: many reviewers describe smooth projects and professional crews, but a meaningful set of comments asks for better follow-through on service and updates.

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.
