Sustainable Energy Group Reviews

Reviewers most often describe the sales process as clear, professional, and tailored to the home, with several saying the proposal and consultation helped them understand their options. A small number of complaints focus on pushy or hostile outreach and concerns about how claims were presented, but those appear less common than the praise.Solar.com's composite of published customer feedback, not a customer quote

Clear, tailored proposals. Reviewers say the consultation and proposal process was organized and informative, with some noting that an engineer visited the property and helped identify the best system options. Representative review excerpt: "Sustainable Energy Group was the only company that sent an engineer out to look at my home and property, giving me the best options of anyone."

Responsive and knowledgeable sales support. Customers describe the salesperson as prompt, responsive, and creative with system options, which helped set expectations before installation. Representative review excerpt: "Tom Benzig was not only prompt, organized and responsive to our questions, but he was also very knowledgeable and creative with options for our solar power system and its installation."

Watch-out on sales conduct. A small set of reviewers report aggressive outreach or say they were dissatisfied with how claims were presented, so the sales experience was not uniformly positive. Representative review excerpt: "When it was clear to them I wasn't interested in solar panels of any kind at 8 pm with random people at my door, they turned VERY NASTY AND HOSTILE."

Feedback on pricing and financing is mostly positive but limited in volume. Some reviewers mention fair pricing or refunds handled smoothly, while a couple of complaints suggest concern about how costs were presented or handled.Solar.com's composite of published customer feedback, not a customer quote

Refunds handled smoothly. One reviewer says an inspection fee was refunded promptly and with a pleasant attitude after the appointment was canceled. Representative review excerpt: "When I cancelled our appointment after discovering we had a switch turned off, they refunded my inspection fee with a cheerful with a pleasant attitude."

Pricing seen as Pricing. Reviewers describe a recurring pattern in this area. Representative review excerpt: "For example, the total for the same energy output was $10,000 less than our Byers quote, which would move our payback to 11 years."

Limited but real pricing concerns. The complaint set is small, but it does include dissatisfaction with how pricing or related expectations were handled, so transparency is not universally praised. Representative review excerpt: "Working with him in any capacity is a mistake."

Communication is one of the weaker areas in the review set. Many reviewers praise follow-up and persistence with utilities or scheduling, but a substantial number describe missed calls, slow responses, or difficulty reaching the company after problems came up.Solar.com's composite of published customer feedback, not a customer quote

Persistent coordination with utilities. Some reviewers say SEG kept calling and emailing the utility until a project moved forward, which they viewed as helpful project management. Representative review excerpt: "SEG diligently called and emailed PG&E every week until it was done."

Responsive in routine interactions. A few customers describe prompt replies, organized follow-up, and a polite refund process when an appointment was canceled. Representative review excerpt: "When I cancelled our appointment after discovering we had a switch turned off, they refunded my inspection fee with a cheerful with a pleasant attitude."

Common complaint: hard to reach. The complaint pattern centers on unanswered calls and emails, with reviewers saying they had trouble getting any response when they needed support or follow-up. Representative review excerpt: "They have closed their office and do not respond to calls or emails."

Timeline feedback is mixed. Several reviewers say projects moved at a good pace or that delays were outside SEG’s control, but others describe long waits, poor follow-up, or work that was not finished when they expected it to be.Solar.com's composite of published customer feedback, not a customer quote

Delays tied to outside factors. Some reviewers say the schedule slipped because of utility delays or supply-chain issues rather than the installation itself. Representative review excerpt: "The work was always great, but on one of the projects PG&E was dragging its feet on their part of the work."

Quick completion on some jobs. A few customers describe the process from consultation through permission to operate as smooth and quick. Representative review excerpt: "Treated us just fine from initial solar consultation, to contract finalization, to solid attractive and quick installation, and permission to operate."

Watch-out on incomplete or delayed closeout. The complaint side includes reports of projects lingering for months, open trenches, and poor follow-through once a job was claimed to be finished. Representative review excerpt: "There's far too much to cover in a Yelp review, but here's where we are six months after they claimed the project was "finished": we still have an open trench..."

Most reviewers describe the crews as professional, courteous, and neat, and several mention clean installations. Still, a meaningful minority report roof or site issues, along with concerns that problems were not addressed promptly after completion.Solar.com's composite of published customer feedback, not a customer quote

Professional crews and cleanup. Reviewers commonly say the installers were respectful, courteous, and neat, and that cleanup was handled well. Representative review excerpt: "The gentlemen that came out to install our panels were respectful, courteous and neat."

Solid installation quality. Some customers describe the installation as attractive, quick, and professionally executed, with positive feedback about the crew’s on-site conduct. Representative review excerpt: "Treated us just fine from initial solar consultation, to contract finalization, to solid attractive and quick installation, and permission to operate."

Site and roof damage concerns. The complaint pattern includes reports of roof-related damage or unfinished site cleanup, plus frustration when follow-up on those issues was slow. Representative review excerpt: "Fast forward to a roofer coming out and discovering (and documenting) that the foot of the solar panels had damaged the flashing and jarred the Ohagan vent on our roof..."

Long-term support and system performance are generally viewed positively. Reviewers often describe helpful troubleshooting, fair inspection pricing, and systems that continue to perform well, though a smaller group reports unresolved service requests or warranty concerns.Solar.com's composite of published customer feedback, not a customer quote

Helpful troubleshooting after install. Several reviewers say SEG quickly addressed minor operating issues and worked through battery or inverter problems until they were resolved. Representative review excerpt: "There were a few very small glitches in operation (between the battery and switchover) and they immediately trouble shot and fixed the glitch."

Good ongoing system value. Some customers report that the system has continued producing as expected and helping reduce energy costs over time. Representative review excerpt: "It has saved our butts the last few winters."

Service follow-through concerns. A smaller set of reviewers describe trouble getting post-install help, including unresolved service requests and concerns about warranty support. Representative review excerpt: "So I guess they won't be honoring any warranty or fixing our system."
