Clear explanations. Reviewers say the team explained options in easy-to-understand language and shared information that helped customers evaluate their solar plans.

Price & financing transparency
Price Transparency6.8/10
Reviewers are mostly positive about pricing, with several noting fair charges or estimates that compared well against expectations. There are also a small number of complaints about billing or perceived overpricing, so this category reads as positive-to-mixed rather than uniformly strong.Solar.com's composite of published customer feedback, not a customer quote
Fair pricing reports. Several reviewers describe the pricing as fair and say they were comfortable with the cost they were quoted or charged. Representative review excerpt: "The price was fair, and I am pleased to be back in contact with them, but I am sure I won't have to see them for a long time!"
Pricing estimate. Some reviewers say the company’s estimate came in below another quote they received, which shaped their view of the overall value. Representative review excerpt: "Before replacing the whole system I received another quote from a trusted source and CleanTech had already beat that price by several hundreds of dollars."
Billing concerns. A small number of reviewers report dissatisfaction with charges or feeling that a service was overpriced, which is the main caution in this category.

Timeline reliability
Timeline Reliability7.3/10
Reviewers generally say projects moved on schedule or were completed efficiently, including cases where the team worked within a short timeframe. The main constraint mentioned in the evidence is permitting or approval timing, which appears to have been driven by outside delays rather than by a broad pattern of missed commitments.Solar.com's composite of published customer feedback, not a customer quote

Representative review excerpt: "Karin and Pablo fit me into their schedule literally within a couple of days and the installation went super smoothly."

Workmanship & site care
Workmanship8.2/10

Long-term support & performance
Long-Term Support7.7/10
Reviewers generally report solid follow-through after installation, including help with repairs, system restoration, and monitoring-related issues. A small amount of negative feedback appears in the evidence, so the category is positive overall but not without occasional service concerns.Solar.com's composite of published customer feedback, not a customer quote
Post-install help. Reviewers say the company helped restore systems after later electrical work or other disruptions, and got equipment back online quickly. Representative review excerpt: "After having our solar installed in 2020, we recently needed help after an electrical panel upgrade disconnected our system."
Repair and update support. Some customers describe the team as effective with older systems, monitoring-related issues, and component updates after the original install. Representative review excerpt: "Clean Tech also updated my solar hot water system replacing some failing components."
