#409 of 678 scored in California by Solar.com Installer Score

How does Oso Holding Group 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 Oso Holding Group 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.

Oso Holding Group 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 Integrity7.2/10

Reviewers generally describe the sales experience as knowledgeable and clear, with several noting patient explanations and helpful proposal guidance. The available review set does not show a complaint pattern in this category, so the feedback here is consistently positive rather than mixed.Solar.com's composite of published customer feedback, not a customer quote

Knowledgeable consultations. Reviewers say the team was knowledgeable and patient when answering questions, including early consultation discussions. The feedback suggests the sales process was informative and low-pressure. Representative review excerpt: "From the very first consultation, the team was incredibly knowledgeable, friendly, and patient with all my questions, whether it was about the HVAC system or the solar installation (which I..."

Strong proposal confidence. Some reviewers describe the sales team as especially capable when explaining what could be done and setting expectations. That points to solid proposal clarity in the collected reviews. Representative review excerpt: "When they say something can’t be done, call OSO!"

Price & financing transparency

Price Transparency6.8/10

Reviewers who mentioned pricing describe it as reasonable and say they did not feel overcharged. The review set is small for this category, but the available feedback does not surface complaints about surprise costs or unclear financing.Solar.com's composite of published customer feedback, not a customer quote

Reasonable pricing. Reviewers say the pricing felt fair and not inflated. The wording suggests customers generally understood what they were paying for. Representative review excerpt: "And last, prices are very reasonable and you won’t feel like you’re getting ripped off."

Communication & coordination

Communication7.4/10

Clear process updates. Reviewers say they were walked through the process clearly and kept updated. That points to steady project coordination and good ownership of the customer experience. Representative review excerpt: "They walked me through everything clearly, didn’t try to upsell me on things I didn’t need, and kept me updated throughout the process."

Fast response times. Several reviewers mention quick responses to questions and helpful office support. The repeated theme is that customers were not left waiting for answers. Representative review excerpt: "Andy customer service or questions you have, they respond quickly."

Helpful phone support. One reviewer highlights a helpful phone interaction and fast service from the office. This reinforces the broader communication pattern seen in the reviews. Representative review excerpt: "Young lady on the phone was very helpful, great fast service!"

Timeline reliability

Timeline Reliability7.0/10

Reviewers describe the company as punctual and able to move projects through permits and inspections. The small evidence set is positive, with no surfaced complaint pattern in the collected reviews.Solar.com's composite of published customer feedback, not a customer quote

On-time execution. Reviewers say the work was completed on time and quickly. That suggests dependable scheduling in the experiences captured here. Representative review excerpt: "They were on time and got the job done quickly."

Representative review excerpt: "They took care of everything from start to finish (permits, inspections, etc) If we ever had a question or concern they were immediately addressed."

Workmanship & site care

Workmanship7.5/10

Reviewers describe professional crews, efficient installation, and clear explanations during the job. In the available reviews, the workmanship feedback is strongly positive and does not surface a complaint pattern.Solar.com's composite of published customer feedback, not a customer quote

Professional crew behavior. Reviewers say the crews were professional and kind during the work. That suggests a respectful on-site experience. Representative review excerpt: "All the guys were professional and kind."

Broad service capability. One reviewer recommends the company across multiple home services, including solar. That reflects a positive view of overall workmanship and service handling. Representative review excerpt: "I’d highly recommend them to anyone looking for roofing, windows, hvac, insulation, or solar!"

Long-term support & performance

Long-Term Support6.0/10

This is the weakest-scoring category in the review set, but the available evidence is limited and still positive. Reviewers mention questions being addressed promptly after the job, though there is not enough feedback here to build a strong picture of long-term performance or warranty support.Solar.com's composite of published customer feedback, not a customer quote

Questions handled after install. Reviewers say questions or concerns were addressed immediately. That suggests post-install support was responsive in the experiences captured here. Representative review excerpt: "They took care of everything from start to finish (permits, inspections, etc) If we ever had a question or concern they were immediately addressed."

No broad pattern in review set. The collected reviews do not provide much detail on monitoring, warranty claims, or long-term system performance. This makes the category harder to assess than the others. Representative review excerpt: "They walked me through everything clearly, didn’t try to upsell me on things I didn’t need, and kept me updated throughout the process."

Bottom line: Across 29 substantive reviews, OSO HOLDING GROUP is described most consistently as responsive, knowledgeable, and organized during the sales and installation process. Overall, the profile reads positive with some limited visibility into post-install experience.

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.
