Knowledgeable sales guidance. Reviewers describe a recurring pattern in this area. Representative review excerpt: "The sales rep knew more than the technical reps at the competition."

Reasonable, Pricing proposals. Some customers describe receiving quotes that seemed fair and detailed, and they credit the company with giving them useful information during the decision process. Representative review excerpt: "We got a competitive reasonable quote from them and the only reason we did not go with them was their financing company didn't offer what we needed."

Proposal and expectation gaps. A smaller set of reviewers report problems with missing or delayed quotes, contracts, or submission steps, and some say the experience did not match what they expected from the outset. Representative review excerpt: "I never received a quote, estimate, contract or anything signed prior to their visit or even after Matt showed up at 5PM on a Friday to briefly look at our..."

Feedback on pricing and financing is mixed: many reviewers describe fair pricing and reasonable financing, while a smaller number report hidden costs, missing paperwork, or frustration tied to rebate and incentive timing. The category lands in the middle because positive value comments are offset by recurring transparency concerns.Solar.com's composite of published customer feedback, not a customer quote

Fair pricing reported. Reviewers often describe the pricing as reasonable or appropriate, and some say they received a clear price for the work early in the process. Representative review excerpt: "Even the financing was reasonable and price appropriate."

Helpful financing in some cases. Some customers mention that the financing felt workable and that the overall price seemed fair for the scope of work. Representative review excerpt: "I contacted coastal solar and they came out within five days and gave me a price for all the work that was less than Tesla's basic visit fee."

Transparency concerns at the end. A smaller group reports hidden costs, incomplete paperwork, or confusion around incentive timing and final project charges. Representative review excerpt: "Upon initiate estimate, their was hidden cost at the end of project."

Most reviewers describe strong communication, responsive follow-up, and good coordination across the project. The few complaints focus on prolonged silence, delayed submissions, or not receiving promised proposals, but those issues appear less common than the praise.Solar.com's composite of published customer feedback, not a customer quote

Consistent updates on-site. Reviewers frequently say the team stayed in touch, explained choices clearly, and coordinated closely during the job.

Representative review excerpt: "I called, texted and emailed Matt numerous times and over 6 months later our SGIP has still not been submitted."

Timeline feedback is generally favorable, with many reviewers describing timely service, quick fixes, and smooth activation. Still, a small number of reviews mention long delays around submissions or scheduling, so reliability is good overall but not perfect.Solar.com's composite of published customer feedback, not a customer quote
