Jamar Power System Reviews

Reviewers most often describe the sales and proposal process as clear, helpful, and grounded in practical system design. A small number of reviews report issues with estimates or expectations not lining up as promised, so this area is positive overall but not spotless.Solar.com's composite of published customer feedback, not a customer quote

Clear proposals and system guidance. Many reviewers say the company took time to evaluate needs, explain options, and put together a workable proposal. Several also describe the process as smooth from initial quote through installation support. Representative review excerpt: "Jamar Power Systems did an excellent job evaluating my solar needs, designing the system, dealing with permits, and installing it."

Responsive, solution-oriented follow-through. Some customers report that the team stepped in to diagnose issues and correct them efficiently, which reinforced trust in the proposal process and the work behind it. Representative review excerpt: "Jamar was the only one who stepped up to diagnose the real issue, replace the faulty components, and get our system running smoothly again — at a fraction of the..."

Estimate or expectation gaps. A few reviews describe frustration when an estimate was delayed or when the scope they expected did not match what was delivered. These complaints appear limited, but they do show up in the review set. Representative review excerpt: "I called the office multiple times, and now one seemed too concerned about the fact that Rob hadn't delivered the promised estimate."

A small number of comments mention being surprised by an invoice amount, so transparency appears strong overall with occasional exceptions.Solar.com's composite of published customer feedback, not a customer quote

Fair pricing and quote consistency. Multiple reviewers say the work was completed at the quoted price or at a cost they felt was reasonable. Representative review excerpt: "They did what they said they would do, when they said they'd do it, and at the price quoted."

Good value on completed work. Customers frequently frame the pricing positively when the work is finished successfully and the results match expectations. The review set includes repeated comments about reasonable cost and good value. Representative review excerpt: "Each time, they have done excellent work for a reasonable price, and everyone I've interacted with has been friendly, professional, and top notch at what they do."

One invoice surprise. One review says the final invoice was higher than expected relative to the labor rate originally quoted. That complaint is isolated, but it is part of the transparency picture. Representative review excerpt: "I just was expecting $100/hr labor as quoted, but was surprised at the invoice."

Communication is a consistent strength in the review corpus, with many customers describing responsive updates, personal follow-up, and help coordinating through each step.

Several describe owners or staff personally stepping in to resolve issues.

Clear updates during the process. Customers also report being kept informed about parts, repairs, and next steps, including cases where the company helped move a project forward after a delay elsewhere in the process. Representative review excerpt: "Even after the replacement, Philip let me know about that failed panel optimizer was down for the past 2 years, and got me in the books for replacing that as..."

A few communication complaints. A small number of reviews describe trouble getting a promised estimate, receiving messages after asking them to stop, or not getting the specific work they requested. These are limited in number but relevant to the category. Representative review excerpt: "I called the office multiple times, and now one seemed too concerned about the fact that Rob hadn't delivered the promised estimate."

Most reviewers say schedules were handled reliably, with installers arriving on time and jobs moving forward as expected. Some reviews acknowledge that permits and related steps can take time, but they also describe the company as keeping customers informed throughout the process.Solar.com's composite of published customer feedback, not a customer quote

On-time work and steady execution. Several reviewers say the team did what it said it would do and showed up when expected. Customers also describe the installation flow as organized and predictable. Representative review excerpt: "They did what they said they would do, when they said they'd do it, and at the price quoted."

Permits and activation handled with guidance. Reviewers commonly mention permit and activation steps as part of a longer process, while noting that someone stayed available to answer questions and keep things moving. That makes the timeline look more managed than rushed. Representative review excerpt: "It’s a long process because of permits and things but someone was always available to answer my questions and guide me through the process."

Installers arriving as scheduled. Some customers specifically note that the installers were on time and explained each step during the work. This supports the broader picture of dependable scheduling. Representative review excerpt: "Their installers were on time and explained every step of the process."

This is one of the strongest areas in the review set. Customers repeatedly describe careful installation, professional crews, and cleanup after the work is done, with no material complaint pattern showing up in the evidence provided.Solar.com's composite of published customer feedback, not a customer quote

Representative review excerpt: "He took the time to make sure everything was installed correctly, cleaned up after the work was completed, and made the entire experience stress-free."

Quality that holds up over time. Some reviews point to systems continuing to work well for years, which supports the impression of solid workmanship. These long-running positive comments reinforce the installation quality theme. Representative review excerpt: "Previously installed my solar panels, which have been working flawlessly for years."

Long-term support and post-install performance receive very strong feedback overall. Reviewers describe helpful warranty assistance, problem-solving after equipment issues, and systems that continue to perform well, while a few comments note warranty or equipment complications that the company still helped navigate.Solar.com's composite of published customer feedback, not a customer quote

Helpful post-install support. Many reviewers say the company stayed involved after installation and helped work through later system issues or warranty-related needs.

Support with equipment or warranty issues. Some reviews mention assistance when an inverter or other component failed, including help navigating manufacturer or warranty processes. These comments reinforce the post-install service strength. Representative review excerpt: "After SunPower's bankruptcy left us with a malfunctioning solar system and no warranty support, every other company I contacted pushed for a full $40k+ replacement that would've torn up our..."

A few post-install complications. A small number of reviews mention equipment failures or warranty timing concerns, but even those accounts often describe the company trying to help. The complaint pattern is limited relative to the positive feedback. Representative review excerpt: "A little disappointed that it was only 8 years old but it was still within the 12 year warranty."
