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

How does Radius 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 Radius 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.

Radius Energy reviews: what customers say

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

Sales & proposal integrity

Sales Integrity7.1/10

Reviewers mostly describe the sales process as knowledgeable and helpful, with several saying proposals felt clear and expectations were set well. The main concern is that a small number of reviewers say post-sale support did not match the pre-sale experience.Solar.com's composite of published customer feedback, not a customer quote

Helpful pre-sale guidance. Reviewers often say the team was knowledgeable, answered questions clearly, and helped them understand the project before signing. Several describe the proposal and planning process as straightforward. Representative review excerpt: "I myself am a contractor and he definitely has shown more client support than just a salesman."

Post-sale expectations issue. One reviewer says the company was very helpful before the sale but difficult to reach after the sale. That pattern appears as the main complaint in this category. Representative review excerpt: "Super helpful before the sale, but can't get any help after the sale."

Confidence in recommendations. Some reviewers describe the sales team as supportive enough that they felt comfortable moving forward with the project. Others emphasize that the staff seemed to explain the system in a practical way. Representative review excerpt: "The crew at Radius are the best, honestly the most knowledgeable about solar in the area!"

Price & financing transparency

Price Transparency6.9/10

The available reviews lean positive on pricing and financing, with customers saying costs were explained clearly and there were no surprises. Reviewers also mention financing help and incentive timing in a way that suggests the process felt manageable.Solar.com's composite of published customer feedback, not a customer quote

Clear pricing experience. Reviewers say the final price and financing details were explained well, and they did not report unexpected charges in the reviews analyzed. Some mention that the process felt transparent from quote through install. Representative review excerpt: "Great customer service and communication from start to finish, they take care of everything including permits and help with financing"

Financing support. Customers also report that the company helped with financing and handled the paperwork side of the process. A few describe the overall experience as organized and easy to follow. Representative review excerpt: "Great service for solar installation and the cash discount was nice too."

Communication & coordination

Communication6.7/10

Most reviewers describe responsive communication and good coordination during the project. Still, a smaller set of reviews says follow-up after installation was difficult, especially when equipment problems came up.Solar.com's composite of published customer feedback, not a customer quote

Responsive follow-up. Many reviewers say the owner and staff responded quickly, followed up when needed, and stayed engaged through the project. Some also describe the team as accommodating around scheduling and homeowner needs. Representative review excerpt: "Despite a few issues that came up post-install, their owner and staff were very responsive, and we were able to navigate everything to get it resolved amicably."

Post-install support gaps. A few reviewers report slow responses or limited help after the sale, especially when troubleshooting equipment or inverter issues. Those comments suggest coordination can weaken once the system is installed. Representative review excerpt: "Problems with equipment failure for months, slow to respond, troubleshooting & tech support is poor."

Hands-on communication. Several customers say they received timely replies and felt the company was willing to work through issues. The pattern in the reviews points to generally strong project communication with some exceptions. Representative review excerpt: "Radius has been awesome with follow up the few times I even needed to contact them."

Timeline reliability

Timeline Reliability6.4/10

Reviews are mixed on timing. Some customers say the installation moved quickly and the company handled permits and coordination well, while a few report delays that stretched the project timeline.Solar.com's composite of published customer feedback, not a customer quote

Fast or flexible scheduling. Several reviewers say the team worked around their schedule and completed the installation quickly. Others describe the process from quote to design to install as smooth and professional. Representative review excerpt: "Radius was flexible with working around our schedule and the solar installation was done in a flash."

Permit and coordination support. Customers also note that the company helped take care of permits and other steps in the process. For some, that support helped keep the project moving. Representative review excerpt: "Great customer service and communication from start to finish, they take care of everything including permits and help with financing"

Delay complaint. One reviewer says an approved plan still took months to install, which points to occasional timeline slippage. That is the main complaint pattern in this category. Representative review excerpt: "It took them 4 months to install their approved plan...."

Workmanship & site care

Workmanship7.5/10

Reviewers are consistently positive about the installation crew’s professionalism and the condition of the worksite. The reviewed feedback emphasizes clean job sites, orderly execution, and a solid installation experience.Solar.com's composite of published customer feedback, not a customer quote

Clean, professional crews. Reviewers say the crew was professional, the worksite was kept clean, and they received calls before workers arrived. That kind of site care shows up repeatedly in the reviews. Representative review excerpt: "Every time they were scheduled to work on our property, we would receive a call to let us know when they would arrive and the work site was always clean..."

Strong install execution. Customers often describe the installation itself as well done and efficient. Several comments suggest the crews handled the job neatly and with care. Representative review excerpt: "This company does an awesome job."

Long-term support & performance

Long-Term Support6.7/10

Most reviewers who discussed post-install support say the company remained helpful after the system was turned on. A smaller set of reviews reports production or monitoring issues that were not resolved to the customer’s satisfaction.Solar.com's composite of published customer feedback, not a customer quote

Helpful after install. Several reviewers say the company answered questions after activation and helped them navigate system issues or setup questions. Some also describe the team as quick to respond when something needed attention. Representative review excerpt: "Most of those contacts were me understanding the system but they were always ready reply no matter how silly my question."

Production and monitoring complaints. A few reviewers report underperformance or monitoring problems and say they were unable to get help resolving them. Those comments suggest post-install support can be uneven when technical issues arise. Representative review excerpt: "My system reports that it's producing 60% of the planned power and they won't help me figure out what the problem is."

Satisfied system owners. Other reviewers say they were satisfied with how the system was performing and appreciated the follow-through they received. These comments keep the overall category from reading fully negative. Representative review excerpt: "I am very satisfied with the system, along with all the $ credits that I have gotten back."

Bottom line: RADIUS ENERGY’s review set is mostly positive, with especially strong feedback on workmanship and generally favorable comments about sales clarity and pricing transparency. The main watch-outs are post-install communication, occasional timeline delays, and a small number of reviews describing unresolved performance or monitoring issues. Overall, the profile reads as solid but not perfect, with the lower scores concentrated in coordination and long-term support.

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.
