How does Greenspire Construction compare where you live? Rankings are local; an installer that leads one city can trail in the next. See how they rank in your city →

Why this differs from star ratings: most five-star reviews say “great company” and stop, and star averages reward that. These category scores only count reviews with concrete evidence, weighted by recency and the reviewer’s track record. A company can hold a strong star average while specific categories score lower; that gap is usually where the real story is. Categories with more complaints than praise are the questions worth asking any bidder, not necessarily dealbreakers.

Where Greenspire Construction builds

County-by-county activity from CPUC records through May 2026.

What this data covers: *Counts on this page, including the totals up top, come from investor-owned-utility interconnection records (SCE, SDG&E, PG&E). Work in municipal-utility territory, such as LADWP or city utilities, and outside California does not appear here, so this company's true totals are higher than shown. Unlike the county rankings, this profile also shows counties below the 250-install ranking floor.

Greenspire Construction reviews: what customers say

An independent synthesis of published customer feedback, updated September 23, 2026. Green marks praise, amber mixed experiences, red complaints.

Sales & proposal integrity

Sales Integrity3.8/10

Reviewers give a mixed picture of the sales experience. Positive reviews describe helpful explanations, useful program information, and clear presentations, while complaints focus on pushy sales tactics, weak follow-through, and disputes about contract expectations and responsibilities.Solar.com's composite of published customer feedback, not a customer quote

Helpful explanations and program guidance. Some reviewers say the sales process was informative and that the team explained available programs clearly. A few also mention same-day follow-up steps and a helpful overall experience. Representative review excerpt: "I liked what they had, made me aware of the programs and same day I signed they had already sent someone to check if my house would be a good..."

Clear presentation for some customers. Several reviews describe the presentation as straightforward and the information as useful during the decision process. These comments suggest some customers felt the proposal was presented clearly. Representative review excerpt: "very good presentation with good information."

Pushy or unclear sales experience. Other reviewers describe pressure to sign, concerns about honesty, and confusion about obligations after the sale. Complaints also mention slow responses when customers later needed information about the contract. Representative review excerpt: "He just looked at my bill, wasted 90 minutes of my time, and was pushy about signing a solar loan contract that is not a good deal and would make..."

Price & financing transparency

Price Transparency3.6/10

Feedback on pricing and financing is mostly negative, with only limited praise. Reviewers describe concerns about loan terms, unexpected costs, and incentive timing, while one review notes a more positive general impression of the company.Solar.com's composite of published customer feedback, not a customer quote

Concerns about loan terms and monthly cost. Several complaints focus on financing being presented in a way reviewers felt was unfavorable, including pressure to sign loan paperwork. One reviewer says the monthly payment ended up higher than expected. Representative review excerpt: "He just looked at my bill, wasted 90 minutes of my time, and was pushy about signing a solar loan contract that is not a good deal and would make..."

Refunds, bonuses, and incentive timing issues. Other reviewers mention disputes over referral bonuses, deposits or repair-related costs, and how incentive timing was explained. Representative review excerpt: "I was told that if I referred a friend, I would receive a 1000 check as a refferal bonus."

Some positive general impressions. A small number of reviewers describe the company as helpful and trustworthy in general terms. These comments are not specific to pricing, but they show that not every reviewer had a negative view of the transaction. Representative review excerpt: "Sometimes it can be hard to determine who wants to genuinely help and who just wants your money."

Communication & coordination

Communication3.5/10

Communication and coordination are a consistent pain point in the review corpus. Positive comments mention prompt answers and helpful guidance, but many reviewers report slow responses, limited follow-up, and customers being left to handle parts of the process themselves.Solar.com's composite of published customer feedback, not a customer quote

Slow follow-up and poor handoffs. Many complaints say customers had to chase updates, wait weeks for replies, or handle coordination tasks themselves. Reviewers also report confusion when issues involved third parties or subcontractors. Representative review excerpt: "7 weeks and 4 calls (from me) later, there has been no follow up from greenspire or sunnova."

Responsive help for some customers. A few reviewers say staff were available to answer questions and helped them feel satisfied with the process. These comments suggest some customers did receive attentive support during their project. Representative review excerpt: "They were always available to answer any questions I had and made sure everything was done to my satisfaction."

Helpful guidance during the transaction. Some reviews describe the team as helpful in navigating the process and working through the transaction. One reviewer also says the company stayed engaged from start to finish. Representative review excerpt: "From the top down the employees and owners of the company are honest and very helpful in aspects of completing and navigating through a transaction."

Timeline reliability

Timeline Reliability4.6/10

Timeline performance sits in the middle range, with one positive note and several complaints about delays. Reviewers describe problems getting permits, utility paperwork, and activation completed on schedule, and some say they were left waiting longer than expected for progress updates.Solar.com's composite of published customer feedback, not a customer quote

Permit and activation delays. Multiple complaints say projects stalled while paperwork or utility steps remained unfinished. Reviewers describe long waits for activation and frustration that the process dragged on for months. Representative review excerpt: "It is now January of 2020 and they still have not been able to complete the paperwork with the LADWP to have the panels activated."

Delays created extra customer effort. Some reviewers report having to contact the utility or push for updates themselves in order to keep the project moving. These comments point to uneven schedule management after the sale. Representative review excerpt: "Every month is a different issue and now they want me to do their work and contact SCE to try and rush application?"

Quick early site check. One reviewer says the company moved quickly at the start by arranging a site check the same day the agreement was signed. That suggests the earliest part of the timeline can move fast for some projects. Representative review excerpt: "I liked what they had, made me aware of the programs and same day I signed they had already sent someone to check if my house would be a good..."

Workmanship & site care

Workmanship5.4/10

Reviews on workmanship and site care are mixed, with a few customers describing a good install and others reporting installation problems. Complaints focus on roof damage, leaks, incomplete materials on install day, and cleanup or repair issues after the crew left.Solar.com's composite of published customer feedback, not a customer quote

Roof damage and leak complaints. Several reviewers report roof problems after installation, including holes left behind and ongoing leaks. These comments indicate site-care concerns were material for some customers. Representative review excerpt: "But what made it worse was they left holes on the roof and took months in order for them to respond for them to only tell them they do not..."

Incomplete or sloppy installation work. Other complaints mention crews arriving without enough product and electrical work that reviewers felt needed redoing. Together, these reviews point to uneven attention to detail on site. Representative review excerpt: "I should've known how incompetent this company is when they showed up on day one and hadn't brought enough product for the installation."

Positive install experience for some. A small number of reviewers describe the installation as a good experience overall. These comments suggest some customers were satisfied with how the project was handled on site. Representative review excerpt: "I had an amazing experience with Greenspire to install solar panels on my home."

Long-term support & performance

Long-Term Support6.1/10

Post-install support is one of the weakest areas in the review set. A few reviewers say their system is performing well, but most complaints focus on systems not working, slow repair handling, and limited help after activation.Solar.com's composite of published customer feedback, not a customer quote

Repair and monitoring follow-through issues. Several complaints say customers struggled to get help after the system was installed or activated. Reviewers describe slow repair timelines, weak status updates, and trouble getting the right parties to respond. Representative review excerpt: "Post- install they called for a repair that was estimated for 2 weeks."

System not working or unresolved after install. Other reviewers report that their solar system was not functioning properly and that support requests went unanswered. These comments show persistent concerns about warranty and service follow-through. Representative review excerpt: "My solar that Greenspire installed has not been working and I have tried to contact them and they have not gotten back to me."

Lower bills for one reviewer. One reviewer says the new system is working and that they have already noticed a noticeable drop in energy bills. This is the clearest positive sign in the post-install feedback. Representative review excerpt: "I'm thrilled with my new solar system and have already noticed a significant decrease in my energy bills."

Bottom line: Greenspire Construction’s review profile is mixed overall, with a Solar.com installer score of 4.6/10. Reviews are most positive about early sales explanations and some install experiences, but they more often raise concerns about communication, pricing clarity, post-install support, and delays in activation or repair.

Important context: this chart shows investor-owned-utility records only. Companies that shift work toward municipal-utility territory (LADWP and city power departments) or other states will show declining bars here even while building steadily elsewhere, and 2025-26 records also lag real installation dates. Treat this as a partial window, not the company's full trajectory.

How we built this data

Methodology: Counts are residential PV interconnections in investor-owned-utility territory (PG&E, SCE, SDG&E) per CPUC Rule 21 public records through May 2026. Postal and name variants are merged. Municipal utility territory such as LADWP, Glendale, Pasadena, Burbank, Anaheim, and Riverside Public Utilities is not included in those CPUC counts. Counts show recorded installations, not quality ratings. Reported costs are self-reported on owned-system interconnections. No installer can pay for placement.

Who we are: Solar.com is a solar marketplace — we connect homeowners with installers and earn a fee when projects move forward. These rankings and scores are computed from public installation records and published customer reviews. No installer can pay for placement, and no installer — including those we work with — can pay to change a score.
