Energy Service Partners Reviews

Reviewers give a split picture of the sales and proposal experience. Many describe helpful, informative reps, while a substantial set says sales promises, system expectations, or contract details did not match what was ultimately delivered.Solar.com's composite of published customer feedback, not a customer quote

Proposal and contract mismatches. Other reviewers describe a gap between what was promised and what was later installed or communicated, including concerns about system size, production expectations, and project status. Representative review excerpt: "Both my contract and ESP’s representative, Geo, stated that the system would make my home self-sufficient and eliminate my electric bill."

Helpful sales guidance. Some reviewers say sales staff were professional, informative, and responsive when explaining the project and answering questions. Representative review excerpt: "I was very hesitant on getting Solar installed, David our sales rep gave me a lot of information, answered all my questions, And kept the communication going throughout the whole..."

This is one of the weakest areas in the review set. Reviewers frequently report confusion about financing, billing, deposits, refunds, and expected savings, with several saying the final costs or payment obligations were not explained clearly up front.Solar.com's composite of published customer feedback, not a customer quote

Unexpected charges and payment issues. Reviewers commonly report surprise costs, billing confusion, or financing terms that did not line up with what they expected after the project moved forward. Representative review excerpt: "They will do things behind the homeowner, they will notify the financial company saying the project is done when the project is still pending."

Refund or credit disputes. Several reviewers say refund timing, rebate timing, or account corrections became points of friction after installation or billing review. Representative review excerpt: "Now with a finshed project they promised a refund in which they decided to cut in half sort of a big screw me would never recommend this company to anyone"

Some pricing experiences were smooth. A smaller group describes the process as straightforward or the pricing as reasonable, but these comments are outweighed by money-related complaints. Representative review excerpt: "I’ve asked around for many quotes and he gets me what I want with a reasonable price."

Communication draws more praise than some other low-rated categories, but problems are still common. Reviewers often mention responsive staff and steady updates, while others report unanswered calls, multiple handoffs, and little ownership of open issues.Solar.com's composite of published customer feedback, not a customer quote

Responsive project support. Many reviewers say coordinators and support staff kept them informed and were helpful throughout the process. Representative review excerpt: "Stephanie has consistently kept me updated on each step of the way and made sure I was in the loop of it all."

Slow or unreachable follow-up. Other reviewers report delayed responses, voicemail-only contact, or difficulty getting a single person to own the project from start to finish. Representative review excerpt: "Get communications from different people, no project manager assigned to my project - so no ONE person understands what is going on."

Timeline feedback is mixed, but delays are a recurring theme. Some customers say installation and activation moved quickly, while many others describe permit, inspection, utility, or follow-up delays that pushed completion out longer than expected.Solar.com's composite of published customer feedback, not a customer quote

Delays in activation or completion. Other reviewers report long waits for permits, inspections, utility coordination, or final activation after the equipment was already installed. Representative review excerpt: "Once the physical system was finally installed, it took ESP Solar forever to coordinate with SoCal Edison for the final power activation."

Snags handled professionally. A smaller set notes that there were project snags or changes, but says the team handled them in a professional way. Representative review excerpt: "There have been a couple of snags during the project, however ESP has provided very professional staff who are on hand to resolve any issues."

Fast work once underway. Some reviewers say the crew worked quickly and the project moved efficiently once it got going. Representative review excerpt: "We had what I assume was a larger residential installation and the service was fully functional within 2 days."

Most reviewers describe installers as professional and the jobsite as well managed, though there are still complaints about installation defects, cleanup issues, or roof-related problems.Solar.com's composite of published customer feedback, not a customer quote

Professional install crews. Many reviewers praise the technicians and installers for being courteous, efficient, and professional on site. Representative review excerpt: "The team was professional, responsive, and very helpful throughout the entire solar installation process."

Minor cleanup or finish issues. A few reviewers mention small site-care concerns such as leftover materials or minor finish issues, even when the installation itself was generally well received. Representative review excerpt: "My only other comment is that there were some screws left behind on the ground and my husband noticed a corner on a panel that maybe might not have been..."

Installation defects reported. Some reviewers say the work left them with wiring, roof, or placement problems that were not resolved promptly. Representative review excerpt: "ESP has since claimed that a report from Tesla shows the system is functioning properly and has refused to correct the improperly wired panels or complete the installation as contracted."

Post-install support is a major pain point in the review set. While some reviewers say their systems are working well and repairs were handled, many more report underperformance, delayed repairs, or difficulty getting warranty and service help after the system was turned on.Solar.com's composite of published customer feedback, not a customer quote

Repair and warranty support delays. Reviewers frequently describe slow responses, repeated follow-up, or difficulty getting post-install issues addressed after the initial job was complete. Representative review excerpt: "The claims specialist Claire does not pick up the phone ever, she just send out a template text every couple of weeks saying they are working hard to get a..."

Performance or monitoring concerns. Some reviewers say the system or battery was not behaving as expected, or that they wanted clearer information when production fell short. Representative review excerpt: "As a result, ESP’s monitoring showed the system functioning properly, while the battery was unable to deliver power to my home."

Systems performing well for some customers. A smaller group says the system is generating power as expected and that the results have been positive after installation. Representative review excerpt: "Very clean and professional installation..a very organized and helpful team ☺️ So far the system is working perfectly and generating power to specifications"
