#457 of 678 scored in California by Solar.com Installer Score

How does Trulysun 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 Trulysun 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.

Trulysun Energy reviews: what customers say

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

Sales & proposal integrity

Sales Integrity6.8/10

Reviewers give this area a modestly positive read, with the available evidence emphasizing a hands-on owner and a strong willingness to earn business. With only one evidence review in this category, there is not much signal about proposal quality or savings expectations beyond that positive impression.Solar.com's composite of published customer feedback, not a customer quote

Hands-on sales approach. Reviewers describe the owner as hands-on and eager to earn the business, which comes across as a positive sign for sales engagement and proposal discussions. Representative review excerpt: "The owner (David) really wanted the business and I could tell was a hands on worker who is growing his business."

Limited evidence base. This category is based on just one substantive review, so there is not enough volume to draw broader conclusions about contract clarity or proposal consistency.

Price & financing transparency

Price Transparency6.7/10

The available review evidence is sparse but leans positive, with a customer describing improved energy production and lower bills after re-installation. Because there is only one evidence review, there is little direct insight into financing terms, deposits, refunds, or surprise-cost concerns.Solar.com's composite of published customer feedback, not a customer quote

Positive outcome after re-installation. One reviewer links the service to stronger production and lower energy bills after the work was completed. Representative review excerpt: "Since the re-installation of the solar panels, we’ve seen a significant improvement in the energy production and is an evident in the energy bills reduction."

Very limited pricing signal. With just one substantive review in this category, the corpus does not provide much detail on final price transparency, financing, or timing-related cost expectations.

Communication & coordination

Communication7.1/10

Reviewers most often describe the team as responsive, professional, and able to keep projects moving through coordination challenges. One complaint notes weak communication tracking and follow-up, so the overall picture is positive but not perfect.Solar.com's composite of published customer feedback, not a customer quote

Responsive day-to-day communication. Several reviewers say the team was responsive, professional, and reliable in its follow-through during the project. Representative review excerpt: "Also, reliable and very responsive with his communication."

Handled coordination challenges. Reviewers report that the company worked through supplier issues, city permitting, and utility coordination while keeping projects moving. Representative review excerpt: "They worked through supplier challenges, city permitting and with PGE."

Communication tracking concern. One reviewer says email communication and follow-up were not well organized, indicating that coordination can break down for some customers. Representative review excerpt: "I prefer email communication but it is clear they do not have an organized way of tracking communications and following up."

Timeline reliability

Timeline Reliability6.5/10

Timeline feedback is mixed but still tilts positive overall. Several reviewers say the company handled permitting, inspections, and scheduling well, while a couple of reviews describe missed inspections and delays.Solar.com's composite of published customer feedback, not a customer quote

On-schedule examples. Some reviewers say the work was completed on the expected date or that the team moved projects through inspection approvals successfully. Representative review excerpt: "I'm a mechanical engineer with high expectations, Trulysun did a excellent installation completing the work on the date and in the time expected."

Permitting and utility coordination. Other reviewers report that the company worked through supplier delays, city permitting, and utility coordination as part of the project timeline. Representative review excerpt: "They worked through supplier challenges, city permitting and with PGE."

Inspection delay complaint. A smaller set of reviews describes failed inspections and missed no-shows, suggesting that timing can slip late in the process. Representative review excerpt: "The panels are on our roof but we have had THREE failed inspections now, counting the one this morning because nobody from TrulySun showed up."

Workmanship & site care

Workmanship7.0/10

Most review evidence describes clean, professional installation work and respectful crews. There are a few complaints about install issues and inspection-related problems, so workmanship appears generally solid but not uniformly smooth.Solar.com's composite of published customer feedback, not a customer quote

Clean, careful installation. Reviewers describe the installation as clean and visually tidy, including thoughtful conduit routing and attention to appearance. Representative review excerpt: "The installation looks very clean, and the crew did a great job making the conduit runs as pleasant to the eye as possible."

Respectful crews and cleanup. Customers also say the crews were respectful, fast, and careful to clean up afterward. Representative review excerpt: "Their crews are respectful, fast and they cleaned up afterwards, making sure our home and experience was positively improved in all steps of their process."

Install and inspection complaints. A few reviews say the team had trouble following install plans or passing inspections, which points to occasional execution issues. Representative review excerpt: "Can't follow install plans, can't pass inspection."

Long-term support & performance

Long-Term Support6.7/10

Post-install feedback is mostly positive, with reviewers mentioning good system care, maintenance guidance, and help when they needed support after the original provider was no longer available. There is also a complaint tied to a recent install, so long-term support looks helpful in some cases but not consistently problem-free.Solar.com's composite of published customer feedback, not a customer quote

Helpful post-install guidance. Reviewers say the company takes time to explain the process and maintenance tips, which suggests support extends beyond the install itself. Representative review excerpt: "They really take the time to ensure proper installation, sharing photos with us and explaining about the process and maintenance tips."

Support for existing systems. One reviewer reports that the team helped when their original solar provider was no longer available, showing some willingness to assist after the initial sale. Representative review excerpt: "The original Solar Company where we purchased our solar system went out of business and we had to find another solar company to help us with this home project."

Recent-install complaint. One review tied to a recent installation reflects dissatisfaction with the service received, indicating that post-install experience may vary. Representative review excerpt: "They are the contracter company by project solar and they installed panels in my house about a month ago."

Bottom line: TRULYSUN ENERGY’s review profile is broadly positive, with especially strong marks for communication, coordination, and generally careful installation work. The main watch-outs are timeline reliability and some inspection-related complaints, while pricing and sales transparency have limited review volume in the available corpus.

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.
