How does Orange County Contracting Services 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 Orange County Contracting Services 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.

Orange County Contracting Services reviews: what customers say

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

Sales & proposal integrity

Sales Integrity7.8/10

Reviewers mostly describe the sales process as clear, low-pressure, and well explained. A smaller set of complaints centers on misunderstandings about contract details, proposal changes, and expectations around included items or follow-through.Solar.com's composite of published customer feedback, not a customer quote

Clear, low-pressure sales. Many reviewers say the proposal process was straightforward, with honest numbers and no pressure. Several mention that the company kept them informed as plans changed to fit city code requirements. Representative review excerpt: "No pressure, clear explanations, honest numbers, and exactly what they promised."

Helpful issue resolution. Some reviewers note that when details needed clarification, staff worked through the issue and kept the project moving. This includes cases where proposal misunderstandings were addressed after the sale. Representative review excerpt: "There was a misunderstanding regarding the panel count in the contact , but Alex from OC Solar went above and beyond to help resolve the issue."

Contract and expectation gaps. A smaller number of reviewers describe mismatches between what they expected and what was reflected in the contract or project details. Complaints also mention promised extras, last-minute changes, or unclear responsibility for certain items. Representative review excerpt: "Although I do enjoy my solar, I was promised a gift card for posting my honest review on social media."

Price & financing transparency

Price Transparency6.7/10

Reviewers are generally positive about fair pricing, but this category is more mixed than others because several complaints involve deposits, refunds, final pricing, and rebate or incentive timing. Some customers also note that financing or add-on costs were not as expected.Solar.com's composite of published customer feedback, not a customer quote

Fair pricing for many customers. Many reviewers describe the pricing as fair and the overall consultation as easy to understand. Some also say the project economics and bill offsets matched what they were told. Representative review excerpt: "Very professional, great communication and fair prices."

Rebate and cost clarity concerns. A subset of reviewers report confusion around rebate timing, deposit handling, or the final amount due. Others mention that added components or pricing details were not fully clear at the outset. Representative review excerpt: "However, a few areas could have been improved: • Communication around the battery rebate process was lacking, though to their credit, they are actively working with the SGIP team to..."

Deposit and final-price complaints. Some complaints describe disputes over deposits, cancellations, inspections, or revised pricing during the process. These reviews suggest that cost expectations were not always aligned with the final project path. Representative review excerpt: "They have kept my deposit after agreeing to cancel the contract based on them no longer able to fulfill the obligations."

Communication & coordination

Communication8.1/10

Reviewers very often describe responsive communication, regular updates, and staff who took ownership of the project. The main complaints involve slow responses, inconsistent handoffs, or periods where customers felt left without clear feedback.Solar.com's composite of published customer feedback, not a customer quote

Prompt, multi-channel updates. Many reviewers say they received timely communication by email, text, or phone and felt kept in the loop throughout the project. Several note that staff coordinated well across different stages and responsibilities. Representative review excerpt: "Whether by email, text, or phone, their responses were always prompt, and I never felt left in the dark."

Customer support ownership. Reviewers also describe situations where customer support stepped in to resolve issues or keep the project moving. In those cases, they say the team handled follow-up professionally and with persistence. Representative review excerpt: "I had an issue with my tesla powerwall failing but OC Solar was able to eventually get it working again and Savannah in customer support did an excellent job in..."

Response delays and missed follow-up. A smaller group reports difficulty getting replies or feeling unsure about next steps. These complaints focus on gaps in responsiveness rather than the overall volume of feedback. Representative review excerpt: "I tried calling designated number numerous times no feedback."

Timeline reliability

Timeline Reliability7.2/10

Reviewers often say installation and permitting moved forward smoothly, with many projects finishing on a reasonable schedule. Still, this category shows a meaningful set of complaints about delays, inspection bottlenecks, and slower-than-expected activation.Solar.com's composite of published customer feedback, not a customer quote

Smooth installs and milestone progress. Many reviewers describe the install week as well coordinated and say key milestones such as inspections and PTO moved ahead predictably. Some also note that the crew arrived prepared and finished the physical work quickly. Representative review excerpt: "The 5 man team arrived at 7am and had everything staged and ready to go at 8am (Permitted construction start time)."

Clear status updates during the process. Reviewers also mention being updated on permits, installation, inspections, and permission to operate as the project advanced. Those customers felt the timeline was managed with enough visibility to understand where things stood. Representative review excerpt: "They kept me updated every step of the way — permits, installation, inspections, and permission to operate — and made sure I understood how to get the most out of..."

Delays and inspection hold-ups. Some complaints say the project took longer than expected or was delayed by scheduling and inspection issues. A few reviewers report that they could not use the system until unresolved inspection steps were completed. Representative review excerpt: "The overall timeline from start to PTO did take about 13 months, which is longer than expected."

Workmanship & site care

Workmanship8.4/10

Reviewers frequently praise the installation crews for professionalism, cleanliness, and efficient work. Complaints are relatively limited, but a few mention roof or site-related damage, unfinished restoration, or installation details that needed follow-up.Solar.com's composite of published customer feedback, not a customer quote

Professional, clean crews. Many reviewers describe the crews as courteous, efficient, and careful on site. Cleanup and overall professionalism are recurring strengths in these reviews. Representative review excerpt: "The crew was professional, courteous, and clean."

Thorough installation work. Several reviewers say the installation was completed efficiently and that the crew handled complex setups well. Some also note that the team checked structural conditions before moving forward. Representative review excerpt: "They installed 14 high quality panels across 3 arrays, a main panel and a Tesla battery all in one day!"

Site-restoration complaints. A small number of complaints mention roof or site issues that needed repair or cleanup after the work. These reviews focus on restoration and follow-up rather than the general quality of every installation. Representative review excerpt: "OC Solar initially installed a few solar panels in this area of the roof and then moved them to other areas, but they didn't install the tiles back."

Long-term support & performance

Long-Term Support8.6/10

Reviewers very often describe the system as working well after activation and say the company stayed involved after install. The few complaints that appear here center on support timing, equipment issues, or incentive timing rather than broad post-install failure.Solar.com's composite of published customer feedback, not a customer quote

Helpful post-install support. Many reviewers say the company continued to communicate after the system was up and running and helped explain how to use the equipment. Some also note that support teams helped resolve problems when they came up. Representative review excerpt: "They continued to communicate once the system was up and running and provided tips for how to configure the new Tesla battery system they installed and it is working great..."

Repairs and troubleshooting support. Reviewers also describe successful follow-up when a battery or system component needed attention. In those cases, they say the issue was identified, explained, and addressed. Representative review excerpt: "He identified the problem, fixed it, and explained it to me — while also completing additional checks to make sure everything would work properly."

Post-install delays or support gaps. A smaller set of reviews mentions PTO timing, rebate-process communication, or a few equipment-related problems after install. These comments suggest that post-install follow-through is usually strong but not uniform in every case. Representative review excerpt: "OCS told me Permission to Operate (PTO) was issued for my system on 6/26; PTO was not actually done until 8/10."

Bottom line: ORANGE COUNTY CONTRACTING SERVICES has a strong overall review profile, with especially high marks for long-term support, workmanship, and communication. The main softer spots are price and financing transparency, plus some timeline and permit-related delays. Reviewers most often describe a professional team that communicates well, while the more critical feedback centers on deposit handling, rebate timing, and occasional project delays.

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.
