How does Solar Technologies 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 Solar Technologies 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.

Solar Technologies reviews: what customers say

An independent synthesis of published customer feedback across Google and Yelp, updated September 28, 2026. Green marks praise, amber mixed experiences, red complaints.

Sales & proposal integrity

Sales Integrity7.6/10

Reviewers mostly describe the sales process as informative, patient, and low-pressure, with several saying the team explained options clearly and stayed helpful through the project. A smaller set of complaints says some customers felt the proposal or expectations did not line up well with later design or installation issues.Solar.com's composite of published customer feedback, not a customer quote

Clear, low-pressure sales process. Reviewers often say the sales team was professional, knowledgeable, and willing to explain options without pressure. Several note that the initial consultation and proposal stage helped them understand the project. Representative review excerpt: "The sales rep was informative, low-pressure, and very professional."

Helpful guidance through options. Customers describe the team as patient when walking through different system choices and construction details. Some also mention the salesperson remained a useful point of contact across the project. Representative review excerpt: "Jason on their sales team is very helpful and well educated not just on the product but also on the construction process."

Proposal expectations not always matched later work. A minority of reviewers say the proposal stage felt strong, but later design or installation issues created disappointment. These comments suggest some gaps between early expectations and what happened during execution. Representative review excerpt: "They were great at making a proposal and getting our money, but there were so many problems with the design and installation."

Price & financing transparency

Price Transparency6.8/10

Feedback on pricing and financing is generally favorable but more divided than other areas. Many reviewers say costs, timelines, and design details were explained clearly, while a smaller group reports surprise costs, pricing dissatisfaction, or other financing-related frustrations.Solar.com's composite of published customer feedback, not a customer quote

Costs explained clearly. Reviewers commonly say the company was straightforward about costs and timelines, with no surprises during the process. Others mention detailed explanations of design choices, projected savings, and overall pricing. Representative review excerpt: "Everything was very straightforward, costs and timelines were explained clearly and we had no surprises."

Transparent walkthrough of pricing details. Some customers report that the salesperson explained system sizing, projected savings, ROI, and total costs in a clear way. A few also mention receiving milestone tables that laid out what to expect along the way. Representative review excerpt: "He was specific regarding recommendations for how many panels and the location of panels for our home, the manufacturer, the effectiveness, projected savings and ROI, all costs, timeline, etc."

Pricing and setup frustrations. A notable minority describe disappointment with final value, unexpected costs, or system setup issues that made the price feel harder to justify. These reviews point to concerns around transparency and incentive timing-related expectations. Representative review excerpt: "We chose Solar Technologies because they were the most reasonably priced of the 3-4 vendors we interviewed, but wish we'd paid another couple thousand dollars and maybe we'd have had..."

Communication & coordination

Communication7.4/10

Most reviewers describe the team as responsive, organized, and easy to work with during installation and handoffs. Still, a meaningful minority say follow-up was slow or missing at key moments, especially when coordination with manufacturers or support partners was needed.Solar.com's composite of published customer feedback, not a customer quote

Responsive and organized coordination. Many customers say the company kept them informed, communicated clearly, and helped move the project along. Some also note detailed status updates and photo reports after work was completed. Representative review excerpt: "Later I received an emailed report detailing what was done, including many before, during and after photos."

Professional crews and clear handoffs. Reviewers frequently mention that crews communicated well and were helpful throughout the process. Several say they felt supported from the first visit through installation and walkthrough. Representative review excerpt: "The installation crews were also very professional and communicated very clearly as well."

Slow follow-up in some cases. A smaller group reports repeated unanswered emails, delayed callbacks, or unresponsive follow-up when issues needed resolution. These complaints often center on project ownership after the initial sale. Representative review excerpt: "I have emailed multiple times and have called twice with no return phone call."

Timeline reliability

Timeline Reliability6.3/10

Timeline feedback is mixed. Many reviewers say the project stayed on track and the install happened within an expected window, but a substantial set describes delays around permits, scheduling, inspections, or activation that stretched the process much longer than expected.Solar.com's composite of published customer feedback, not a customer quote

Projects sometimes finished on schedule. Some reviewers say the team delivered within the target timeline and handled the work efficiently from site visit through final walkthrough. Others mention fast installation once crews were on site. Representative review excerpt: "They were able to get us setup with solar and a home battery within our target timeline and very helpful throughout the process."

Install day execution could be efficient. Customers describe crew work as professional and quick in some cases, with installation completed in a short window. These reviews suggest the on-site portion often moved smoothly once it began. Representative review excerpt: "On day of install Mycal's crew was great - professional and fast, got done in just 2 days!"

Delays and missed updates were a recurring issue. A notable group reports long waits, limited updates, or permit-related delays that pushed projects far beyond the original schedule. Some reviewers say the delay affected activation timing or required repeated rescheduling. Representative review excerpt: "Nobody cared to update us even once until, suddenly, we got the installation date - which was almost two years after the day we signed for the program."

Workmanship & site care

Workmanship8.9/10

Workmanship is one of the strongest areas in the review set. Reviewers frequently praise the crews for careful installation, professionalism, clean job sites, and willingness to make fixes when needed, while only a small number mention installation mistakes or site-related issues.Solar.com's composite of published customer feedback, not a customer quote

Careful, clean installation work. Many customers describe the crews as professional, efficient, and attentive to details on site. Several specifically note clean work, tidy conduit runs, and respect for the property during installation. Representative review excerpt: "Clean install and accommodated my requests on joiner box, conduit run and breaker locations."

Crew professionalism stands out. Reviewers often say the installers worked hard, communicated clearly, and cleaned up after the job. Some also mention extra effort around trimming, guarding, or other site-specific details. Representative review excerpt: "Jesse a d Javier worked hard and carefully cleani g the redwood under tha panels, installing critter guard and cleaning all the panels."

A few installation mistakes surfaced. A small number of reviews mention problems such as shade placement, broken tiles, or other installation-related hiccups that needed correction. These complaints are present but far less common than praise. Representative review excerpt: "- The mobile app is very clunky, it's basically a webview - Installation wasn't done properly initially, panels were installed where there was shade on the roof, I had to..."

Long-term support & performance

Long-Term Support8.7/10

Post-install feedback is strongly positive overall. Reviewers frequently report good system production and diligent follow-up on repairs or small issues, though a smaller set says warranty support or repair response took too long or felt inconsistent.Solar.com's composite of published customer feedback, not a customer quote

Strong ongoing system results. Many reviewers say their systems are performing well after installation and contributing meaningfully to home energy needs. Some also mention monitoring and general post-install operation in positive terms. Representative review excerpt: "Now my panels are providing 50% of the needed energy to my home & battery, and I'm drawing about 45% electricity needed from the grid (after dark & after the..."

Responsive follow-up on repairs. Several customers describe the company as responsible when a component needed attention, including cases where follow-up continued until the issue was resolved. These reviews suggest solid post-install ownership in many situations. Representative review excerpt: "I had a minor issue where a replaced optimizer didn't connect properly at first, but they were very responsible and followed up diligently."

Warranty and repair delays came up for some. A smaller group reports slow service, delayed repairs, or disappointment with warranty handling after turn-on. These complaints center on support timing rather than the initial installation itself. Representative review excerpt: "Bottom line, they don’t stand by the warranty for systems installed by the company they bought and are slow to repair/support broken systems."

Bottom line: Solar Technologies’ review profile is strongest on workmanship and long-term system performance, with many customers describing careful crews and solid post-install results. The main softer spots are timeline reliability and price transparency, where reviewers more often mention delays, follow-up gaps, or unexpected friction. Overall, the review set is positive, but not without recurring complaints around coordination and schedule management.

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.
