How does Senga Energy 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 Senga Energy 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.

Senga Energy reviews: what customers say

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

Sales & proposal integrity

Sales Integrity7.8/10

Reviewers mostly describe SENGA's sales process as clear and informative, especially when it comes to walking through financing, permitting, and the pros and cons of a proposal. The smaller set of complaints centers on pressure, delayed or unclear contract details, and a few reports of bait-and-switch style expectations.Solar.com's composite of published customer feedback, not a customer quote

Clear explanations. Many reviewers say the team was transparent and willing to answer detailed questions about the process, financing, and approvals. These accounts describe a sales experience that felt informative rather than rushed. Representative review excerpt: "They were very helpful, responsive and transparent throughout the whole process - we had lots of questions about the installation process, the financing, and permitting and approvals."

Honest guidance. Some reviewers report that representatives laid out the tradeoffs plainly and helped them understand the proposal before moving forward. That kind of feedback appears often in the positive reviews. Representative review excerpt: "He guided us through the entire process, providing a transparent breakdown of the pros and cons while answering every question we had."

Pressure and contract concerns. A smaller group of reviewers describe pressure tactics, contract confusion, or proposals that did not match what they expected. These complaints are not the majority, but they are a recurring watch-out in the feedback. Representative review excerpt: "I learned later this was a trick as there is no prelinary application and I did not see the actual contract till 8 months later."

Price & financing transparency

Price Transparency7.1/10

Most reviewers who mention pricing or financing describe helpful guidance and a willingness to work through payment structures. At the same time, some reviews report surprise price changes, deposit or timing concerns, and confusion tied to the final system size or incentive timing.Solar.com's composite of published customer feedback, not a customer quote

Helpful financing support. Several reviewers say the team helped them set up financing and explained payment timing clearly. These comments suggest the financing conversation often felt manageable and straightforward. Representative review excerpt: "He patiently listened, helped us thru what we wanted, set up the financing and got the job done!!"

Transparent payment setup. Reviewers also mention payment terms that were explained in a way that felt fair, including cases where payments were not due until the system was up and running. That points to generally solid transparency for many customers. Representative review excerpt: "He'll help you with financing and payments aren't required until the system is up and running."

Price surprises. Some reviewers report major changes from the original quote or felt the system size and battery setup did not match what they expected. These complaints keep this category from reading as fully smooth. Representative review excerpt: "I was quoted Tesla retail prices for the batteries, but when they finally got the batteries I was requoted a price 300% above retail."

Communication & coordination

Communication8.0/10

Reviewers mostly describe steady communication, helpful answers, and clear coordination through the project. The main complaints involve missed calls, poor follow-up, and a few reports that help requests were not answered promptly.Solar.com's composite of published customer feedback, not a customer quote

Responsive updates. Many customers say the team stayed responsive and transparent while the project moved forward. These reviews describe regular updates and clear handoffs during the install process. Representative review excerpt: "They were very helpful, responsive and transparent throughout the whole process - we had lots of questions about the installation process, the financing, and permitting and approvals."

Helpful project guidance. Reviewers also say staff members answered questions thoroughly and helped them feel more comfortable with the process. That suggests the coordination experience was often personal and attentive. Representative review excerpt: "He guided us through the entire process, providing a transparent breakdown of the pros and cons while answering every question we had."

Follow-up gaps. A smaller group reports difficulty getting calls returned or getting support after issues came up. These reviews point to uneven follow-through in some cases. Representative review excerpt: "I put solar with this company I have had multiple failures I call for help and they never answer the person who helped me his name is Juan he never..."

Timeline reliability

Timeline Reliability7.4/10

Many reviewers say the process moved forward with clear updates and ultimately reached installation or activation, but the timeline is a weaker area than sales or communication. Complaints center on missed appointments, slow permitting or PTO, and long waits for final fixes or activation.Solar.com's composite of published customer feedback, not a customer quote

Process updates. Some reviewers say they were kept informed as permits and installation moved along, which helped the project feel organized. These comments frame the timeline as workable even when the process took time. Representative review excerpt: "He is surely committed to his job, he reaches out from time to time, gives us update on the process of getting the panels until it was finally installed and..."

Activation delays. A few reviewers describe delays around permission to operate or final utility activation even after the main install was complete. Those accounts suggest the back end of the project can take longer than customers expect. Representative review excerpt: "However, the only hiccup in an otherwise flawless experience has been the delay in obtaining Permission to Operate (PTO) from PG&E."

Missed appointments and unfinished fixes. Other complaints mention no-shows, long waits after inspections, or work that was still unresolved months later. This is the clearest operational watch-out in the timeline feedback. Representative review excerpt: "It's been months since our final inspection with the city I've been waiting for my roof tile to get re installed but I get no answer."

Workmanship & site care

Workmanship8.4/10

Reviewers generally praise the quality of the installation crew, describing clean work, professionalism, and strong attention to the home. The limited complaints focus on wiring problems, incomplete fixes, or installations that did not perform as expected.Solar.com's composite of published customer feedback, not a customer quote

Clean, professional crews. Many reviewers describe the installation team as clean, polite, and efficient. These comments suggest the on-site experience is often handled carefully. Representative review excerpt: "The installation and construction crew did an AMAZING job, clean, polite, on time, efficient, and the workmanship was BEAUTIFUL with ZERO issues."

Attention to appearance. Some customers say the finished work was neat enough that it improved the look of the home rather than just adding equipment. That points to solid attention to site care and finish quality. Representative review excerpt: "The installation crew is TOP notch and took care to make the home look like it had a makeover instead just an installation."

Installation errors. A few reviewers report wiring or setup mistakes that required fixes or left part of the system not working as intended. These are uncommon in the corpus, but they are a real complaint pattern. Representative review excerpt: "This one the head electrician didn’t connect the wire to the screw and tighten it so the connection was made."

Long-term support & performance

Long-Term Support8.0/10

Most reviewers who discuss post-install support say the system is working well and that staff stayed available for questions after completion. The complaints point to warranty or service follow-up issues, including calls that were not answered and reports of systems or batteries not performing as expected.Solar.com's composite of published customer feedback, not a customer quote

Ongoing follow-up. Some reviewers say staff stayed in touch after installation to make sure everything continued running smoothly. That kind of follow-through appears repeatedly in the positive feedback. Representative review excerpt: "After the installation is done and the system is working, Todd keeps in touch for months afterwards to make sure everything is running smoothly."

System working as expected. Other reviewers report that the system performed well after turn-on and helped them reduce dependence on the grid. These comments support a generally favorable view of long-term performance. Representative review excerpt: "Senga Energy was excellent communicating every step along the way, system is performing as I hoped, helping reduce our dependence on the grid."

Service and performance complaints. A smaller set of reviews describes broken equipment, weak battery performance, or difficulty reaching support after problems came up. These complaints show that post-install service is not uniformly smooth. Representative review excerpt: "I put solar with this company I have had multiple failures I call for help and they never answer the person who helped me his name is Juan he never..."

Bottom line: SENGA ENERGY's review profile is broadly positive, with strongest feedback around workmanship, communication, and the clarity of its sales conversations. The main softer spots are timeline reliability and price or activation transparency, where some reviewers describe delays, quote changes, or follow-up gaps. Overall, the corpus shows a company that many customers feel handled the process well, while a smaller but material set reported issues after the sale or during project completion.

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.
