How does Semper Solaris 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 Semper Solaris 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.

Semper Solaris 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 Integrity6.8/10

Reviewers more often describe the sales process as clear, informative, and low-pressure, with consultants answering questions and walking customers through options. Complaints are still material, though, and focus on pressure to sign, proposals that did not match later experience, and expectations that were not fully explained up front.Solar.com's composite of published customer feedback, not a customer quote

Clear and low-pressure sales. Many reviewers say the sales conversation felt honest and helpful, with reps taking time to explain options and process details. Several note that they did not feel pushed into a purchase. Representative review excerpt: "Our consultant, Phil Valverde, exceeded expectations—he was professional, honest, and had a great personality throughout the entire process."

Helpful step-by-step guidance. Customers also describe being walked through the process in a way that made the proposal easier to understand. These reviews frame the early stage as responsive and informative. Representative review excerpt: "He walked me through every step of the process and was always (literally always!) available to chat with me throughout the solar installation process."

Pressure and expectation gaps. A smaller but meaningful set of reviewers report pressure tactics or information gaps around contract terms, permitting, or product expectations. These comments suggest the proposal stage was not always as clear as customers expected. Representative review excerpt: "Imagine the.worst-high pressure sales."

Price & financing transparency

Price Transparency3.9/10

Price and financing reviews are mixed to negative overall. Some reviewers say pricing, estimates, and financing choices were explained clearly, but a substantial share describe surprise costs, refund or payment frustration, and rebate or incentive timing problems.Solar.com's composite of published customer feedback, not a customer quote

Unexpected charges and payment friction. Negative reviews commonly mention surprise costs, difficulty getting money back, or payment-related frustration. Some also report concerns tied to rebate timing or payment expectations not matching what they understood upfront. Representative review excerpt: "Imagine it's very difficult to get the money back and that meanwhile your method of payment.is charging 23.9% interest."

Clear financing explanations. Positive reviews say staff explained estimates and financing choices in a straightforward way. Some customers also felt the overall value was workable once the numbers were laid out. Representative review excerpt: "Phil did an outstanding job explaining our solar system options, walking us through estimates, and clearly outlining financing choices."

Helpful rate and rebate guidance. A number of reviewers describe receiving useful help with financing terms and rebate-related logistics. These customers present the process as manageable when the paperwork was handled well. Representative review excerpt: "They helped me get a super low financing rate financing and got me a massive rebate on my batteries."

Communication & coordination

Communication6.7/10

Many reviewers praise responsive staff, clear updates, and strong follow-through when projects become complicated. At the same time, complaints are frequent enough to keep this area mixed, especially around slow callbacks, handoffs between staff, and difficulty getting post-sale answers.Solar.com's composite of published customer feedback, not a customer quote

Responsive project follow-through. Positive reviews often describe staff who stayed available, answered questions, and kept customers informed through the process. These comments emphasize ownership and consistent follow-up. Representative review excerpt: "He walked me through every step of the process and was always (literally always!) available to chat with me throughout the solar installation process."

Strong coordination on complicated jobs. Some reviewers say the company kept the project moving even when issues arose, with updates and escalation to the right person. This side of the feedback points to solid coordination once a problem was identified. Representative review excerpt: "If you want a company that will advocate for you, communicate honestly, and deliver even when the process gets complicated, I highly recommend Semper Solaris — and especially Jonathan Kibler"

Slow callbacks and support gaps. Negative reviews describe delayed responses, unanswered messages, and difficulty getting clear status updates. Several also mention that communication was better during sales than after the project was underway. Representative review excerpt: "NO one in customer support has given me any real answers -- someone named Miesha opened a case and gave me an update for 3 weeks in a row that..."

Timeline reliability

Timeline Reliability4.9/10

Timeline feedback leans negative because reviewers frequently mention delays, missed timing expectations, and slow movement through permits, inspections, or utility activation. Still, some customers say the process stayed on track or eventually moved forward with help from staff who kept checking in.Solar.com's composite of published customer feedback, not a customer quote

On-time or efficient projects. A portion of reviewers say the project moved efficiently and that the timeline matched what they were told. These comments tend to credit the company with keeping the process organized once work started. Representative review excerpt: "We faced zero delays, and the timeline provided was spot on."

Helpful progress through approvals. Other customers describe support with inspections, documentation, and utility or HOA steps that helped keep the job moving. Even when the process was still in progress, these reviews show staff trying to manage the next steps. Representative review excerpt: "They came out quickly to do the initial inspection required to complete the project workorder, then gave me all the support documentation for HOA approval."

Delays and activation problems. Complaints focus on projects taking far longer than expected, including delayed installations, wrong forms, and slow permission to operate. Reviewers also report frustration when promised dates slipped or activation remained unresolved. Representative review excerpt: "1 year to complete my solar installation - I had to work with SDGE and find out that semper submitted the wrong application more than once."

Workmanship & site care

Workmanship7.5/10

Workmanship is a relative strength in the review corpus, with many customers praising professional crews, efficient installs, and careful handling of roof or equipment work. Even so, some reviewers report property damage, uneven finish quality, or site-care issues that were not fully resolved.Solar.com's composite of published customer feedback, not a customer quote

Professional, efficient crews. Many reviewers describe the installation team as professional, efficient, and careful on site. These comments often pair good workmanship with a clean, organized job. Representative review excerpt: "The installation team was equally impressive—efficient, professional, and delivered excellent work."

High-quality finished work. Customers also say the solar and roofing work was completed with solid quality and attention to detail. Several note that the crew cleaned up well and kept the site presentable during the job. Representative review excerpt: "The solar/roofing job was completed with high quality and efficiency, and the team was dedicated to the project."

Damage and cleanup concerns. Negative reviews mention damaged property, roof or gutter issues, and incomplete site restoration. Some also say fixes were only partial or follow-up on damage was slow. Representative review excerpt: "I have not been contacted - this is par for the course and as I mentioned I am still waiting to resolve the damaged gutter issue and Gateway box replacement."

Long-term support & performance

Long-Term Support8.1/10

Post-install feedback is strongly positive overall, with many reviewers saying support helped restore system function, troubleshoot app or inverter issues, and handle warranty-related repairs. Complaints still appear, but they are a smaller share than the praise and typically focus on delayed service or systems that needed follow-up attention.Solar.com's composite of published customer feedback, not a customer quote

Helpful troubleshooting and repairs. Positive reviews describe prompt technical help, including support for app issues, inverter replacement, and service that restored full function. Customers often frame these interactions as efficient and knowledgeable. Representative review excerpt: "Daisy Trejo provide excellent and prompt service in assisting me with replacing a defective solar inverter which was under warranty, and also worked with Solar Edge to arrange for a..."

Good long-term service response. Some reviewers say even years after installation, the company still helped get a technician involved and move the repair forward. This suggests post-install support can remain active when a system issue comes up later. Representative review excerpt: "7 years after installing the solar unit it stopped working, but after one phone call they had a technician on the phone with me and then had a technician visit..."

Outages and slow service follow-up. Negative reviews mention systems not operating as expected, monitoring or app issues, and delays in getting service scheduled. These comments point to occasional problems with responsiveness after activation. Representative review excerpt: "No one from the company bothered to tell me about the solar edge app so one year we produced ZERO ELECTRICITY because the system was off and I had no..."

Bottom line: Semper Solaris’ review profile is strongest in workmanship and long-term support, while sales and communication are more mixed but still often positive. The biggest weak spots are price/financing transparency and timeline reliability, where reviewers more often describe delays, unclear costs, or frustration with follow-through.

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.
