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

How does One Nation 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 One Nation 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.

One Nation Energy reviews: what customers say

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

Sales & proposal integrity

Sales Integrity7.4/10

Reviewers generally describe the sales and proposal process as clear, honest, and easy to work with. The category is positive overall, though the score suggests there is still some room for improvement in how consistently expectations and proposal details are handled.Solar.com's composite of published customer feedback, not a customer quote

Clear and honest sales approach. Reviewers say the team was straightforward, down to earth, and transparent during the sales process. Several describe feeling comfortable moving forward because the company explained options well. Representative review excerpt: "Extremely down to earth, honest, transparent, passionate about his work, and his attention to detail is unparalleled."

Good first impression from start to finish. Some reviewers describe the experience as excellent from the beginning through completion. Their comments suggest the proposal process set a confident tone for the rest of the project. Representative review excerpt: "Tony with One Nation Energy is nothing but excellent from start to finish."

Strong overall recommendation. A number of reviewers recommend the company for solar and related home projects. This points to generally favorable expectations around sales integrity and proposal quality. Representative review excerpt: "Highly recommend for anyone looking to do solar, roofing, or any home improvement project for their home!"

Price & financing transparency

Price Transparency6.8/10

Review evidence here is limited, but the available feedback is positive. The score is more moderate than the strongest categories, so price and financing clarity appears generally well received without a large amount of detail in the review set.Solar.com's composite of published customer feedback, not a customer quote

Satisfied repeat customer. One reviewer says they used the company for two properties and were very pleased with the results. That feedback suggests the pricing or financing experience was acceptable across multiple projects. Representative review excerpt: "I’ve used One Nation Solar for two properties, my primary residence and an ADU, and have been very pleased with the results."

Limited direct detail. Only one evidence review was available for this category, so the score should be read cautiously. The review set does not provide enough detail to identify recurring concerns around deposits, refunds, or surprise costs. Representative review excerpt: "I’ve used One Nation Solar for two properties, my primary residence and an ADU, and have been very pleased with the results."

Communication & coordination

Communication7.6/10

Reviewers consistently describe the team as responsive and easy to coordinate with. With a score above 7.0 and no complaints in the evidence set, this category reads strongly positive overall.Solar.com's composite of published customer feedback, not a customer quote

Responsive during the project. Reviewers say the team stayed responsive and handled communication well throughout the job. Several comments frame the coordination experience as smooth and reassuring. Representative review excerpt: "Responsive team during the hottest days of the summer❤️❤️❤️."

Strong end-to-end ownership. Some reviewers describe the company as excellent from start to finish, which suggests good handoffs and follow-through. The feedback points to steady project ownership rather than gaps in communication. Representative review excerpt: "Tony with One Nation Energy is nothing but excellent from start to finish."

Helpful support after setup. Reviewers also mention the monitoring app and ongoing updates in a positive way. That suggests communication continued after installation, not just during the sale and build phases. Representative review excerpt: "Once the monitoring app is set up you will be stuck on it 24/7 watching those green numbers pile up in your pocket !"

Timeline reliability

Timeline Reliability7.1/10

The timeline feedback is positive, with reviewers describing the process as dependable and well explained. Because the category score sits in the mid-6 range, it reads as generally good but not as consistently strong as the highest-scoring communication feedback.Solar.com's composite of published customer feedback, not a customer quote

Clear guidance through the process. Reviewers say the company helped them understand their options and what would work best for their situation. That kind of early guidance can help projects move more predictably. Representative review excerpt: "These guys are incredibly honest from the beginning and helped me better understand all my options and what would be best for my situation."

Project flow described positively. Some reviewers describe the overall installation experience as one of the best decisions they made as homeowners. That language suggests the timeline and activation process felt manageable to them. Representative review excerpt: "Working with One Nation Energy to get solar installed at my home was one of the best decisions I’ve made as a homeowner."

Monitoring set up after completion. A reviewer mentions the monitoring app being set up and becoming part of the ongoing experience. This implies the project reached completion and moved into the post-activation stage without a reported issue. Representative review excerpt: "Once the monitoring app is set up you will be stuck on it 24/7 watching those green numbers pile up in your pocket !"

Workmanship & site care

Workmanship7.7/10

Reviewers describe the installation crew as careful, professional, and attentive to the home. The category is mostly positive, with the score suggesting generally solid workmanship rather than an exceptional level of praise.Solar.com's composite of published customer feedback, not a customer quote

Installation quality praised. One reviewer says the company did an amazing job supplying and installing the panels. That points to strong satisfaction with the actual build quality. Representative review excerpt: "⭐⭐⭐⭐⭐ One Nation Energy Company did an absolutely amazing job supplying and installing my solar panels."

Careful with roof and solar work. Another reviewer says the company took very good care of everything related to the roof and solar installation. This suggests attention to site care and handling of the home during the project. Representative review excerpt: "One Nation took very good care of everything regarding the roof and solar installation."

Professional from the beginning. Reviewers also describe the team as honest and helpful in explaining what would work best for their situation. That feedback reflects well on professionalism during the site visit and installation planning stages. Representative review excerpt: "These guys are incredibly honest from the beginning and helped me better understand all my options and what would be best for my situation."

Long-term support & performance

Long-Term Support7.2/10

Post-install feedback is positive, with reviewers saying the company remained helpful after the system was turned on. The score is solid but not especially high, so the category looks reliable without a large volume of detailed warranty or repair examples.Solar.com's composite of published customer feedback, not a customer quote

Help available after installation. Reviewers say it is reassuring to know the team is there if issues come up. That indicates positive experiences with post-install support and problem resolution. Representative review excerpt: "It is great to know that if I ever have any issues they are right there to help fix everything!"

Ongoing support during the solar journey. Some reviewers describe the company as a tremendous help throughout the full solar journey. This suggests support continued beyond the initial install. Representative review excerpt: "One Nation Energy has been a tremendous help during our whole journey of being a solar household."

Monitoring and performance visibility. A reviewer mentions watching the monitoring app and seeing strong system output after setup. That implies the system was performing as expected and remained visible to the customer after activation. Representative review excerpt: "Once the monitoring app is set up you will be stuck on it 24/7 watching those green numbers pile up in your pocket !"

Bottom line: One Nation Energy’s review profile is broadly positive, with especially strong marks for communication and generally favorable feedback across sales, installation, and post-install support. The more moderate scores in pricing, timeline, workmanship, and long-term support suggest solid experiences overall, but with less evidence and less consistency than the strongest category.

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.
