How does Spartan Home 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 Spartan Home 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.

Spartan Home Services 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 Integrity8.0/10

Reviewers most often describe the sales process as clear, honest, and educational. Praise centers on upfront explanations, helpful consultations, and a lack of pressure, while a small set of complaints mentions repeated outreach, unclear expectations, or frustration with how needs were framed.Solar.com's composite of published customer feedback, not a customer quote

Upfront and educational approach. Many reviewers say the team explained options in a way that made the proposal easier to understand and helped them feel informed about what was or was not needed. Representative review excerpt: "What really stood out was the value he brought through his attention to detail, honesty, and ability to educate us on the best options for our home and budget."

No-pressure consultations. Several reviews describe a consultative sales style, including feedback that the representative did not push unnecessary work and was candid about the roof condition. Representative review excerpt: "After the inspection he did not try to up-sale me on something that I didn't need and he was the honest with me that my roof was in decent shape..."

Unwanted outreach or confusing framing. The main complaints focus on persistent calls or voicemails, plus a smaller number of reviewers who felt the messaging around needed work was unclear or not handled well. Representative review excerpt: "Despite doing NO searches for any such services I have received over 7 phone calls and voicemails from this company in less than 2 days."

Price & financing transparency

Price Transparency6.7/10

Reviews are mixed on pricing and financing. Some customers say the company explained costs, financing, rebates, and extra charges clearly, but others report dissatisfaction around deposits, minimum job pricing, or payment timing tied to project completion.Solar.com's composite of published customer feedback, not a customer quote

Clear cost breakdowns. Positive reviews say the team broke down costs and financing in a straightforward way and explained additional charges when they came up. Representative review excerpt: "He provided all the information I needed and broke down the cost and financing in an easy to understand way."

Helpful with rebates and financing. Some reviewers also mention that staff helped them understand rebate timing and financing options without pressure. Representative review excerpt: "Daniel made a seamless effort showing me all the rebates and info needed to help with coats of solar installs."

Payment and refund frustrations. Complaint patterns include minimum pricing concerns, deposit or payment disputes, and a few reviews describing frustration when money was tied to unfinished work or a system that had not begun producing. Representative review excerpt: "Despite this, the loan funded after “final inspection,” so I’ve been making payments on a system that has never produced power."

Communication & coordination

Communication8.0/10

Communication is a consistent strength in the review corpus. Reviewers frequently describe responsive staff, helpful follow-up, and organized project handoffs, though a smaller set reports missed updates, slow responses, or difficulty getting issues resolved after escalation.Solar.com's composite of published customer feedback, not a customer quote

Responsive throughout the project. Many reviewers say the company was quick to respond, kept them informed, and followed up well from quote through completion. Representative review excerpt: "Carissa was fantastic with communication and follow up from start to finish."

Clear project ownership. Some customers highlight coordinated handoffs, including project managers who reviewed the site and discussed scope before work began. Representative review excerpt: "Next, project manager Chris got with us to survey the site and discuss the design , scope, and extent of the project."

Delayed or inconsistent follow-up. The complaint pattern centers on missed callbacks, vague updates, or long gaps in communication when reviewers were seeking resolution on an issue. Representative review excerpt: "When escalated to ownership, the response has been finger-pointing at the equipment vendor, vague updates, and no firm timeline or accountability."

Timeline reliability

Timeline Reliability7.4/10

Most reviewers describe the company as reasonably reliable on timing, with several noting on-schedule work and completion within the estimated window. Still, a smaller group reports delays in follow-up, schedule changes, or uncertainty about next steps after signing.Solar.com's composite of published customer feedback, not a customer quote

Generally on time. Positive reviews say meetings and installations happened on schedule and that the crew completed work within the promised timeframe. Representative review excerpt: "On time, on schedule, master electrician Ryan led his team in the required installation of the batteries, the controller, shutoff, and tie in to the gateway."

Stayed within estimated window. Several customers mention the job finishing on time or with only a small extension when extra work was needed. Representative review excerpt: "Spartan completed their work within the estimated timeframe, and cleaned up the site appropriately when finished."

Schedule uncertainty after contract. The main complaint theme is that some reviewers did not receive timely progress updates or were left unsure when repairs or follow-up work would begin. Representative review excerpt: "After signing the contract, we never heard back from rep to check on the progress or schedule of our project."

Workmanship & site care

Workmanship8.6/10

Workmanship is one of the strongest-rated areas in the review set. Reviewers often praise professional crews, careful installation, and cleanup, while complaints are relatively limited and tend to focus on specific quality issues, site damage, or work that did not match expectations.Solar.com's composite of published customer feedback, not a customer quote

Professional installation crews. Many reviewers describe the crews as courteous, efficient, and professional from estimate to completion. Representative review excerpt: "From my first meeting to assess my roof and provide an estimate to completion of the job, Spartan's crew was professional and courteous."

Clean job sites. Some reviews specifically mention quick work and cleanup after the job, including removal of trash and leaving the site in good shape. Representative review excerpt: "Also, due to the additional wood work needed, it took only one extra day and the installation crew beat the big rain storm (happened the day after roof was completed)!!!"

Isolated quality concerns. The limited complaints mention roof or site issues such as leaks, unfinished details, or work that reviewers felt did not match the agreed scope. Representative review excerpt: "Do not them they subbed out the work to another roofer, laid shingle on existing ones and use sheets of roof shingles in areas not what we agreed on do..."

Long-term support & performance

Long-Term Support7.7/10

Post-install feedback is generally positive, with reviewers describing helpful warranty guidance and systems that perform well after activation. A small number of complaints mention systems that were not operating as expected or difficulty getting follow-up support.Solar.com's composite of published customer feedback, not a customer quote

Warranty guidance and follow-through. Some reviewers say staff helped them navigate manufacturer warranty coverage and coordinated replacement support after installation. Representative review excerpt: "Joel, Mick, and Chris got me completely care of though: they told me how to contact Enphase and get a replacement microinverter under my warranty coverage and then came out..."

Systems performing well after install. Other reviews report that the installed roof, solar, and battery setup continued to work as expected after completion. Representative review excerpt: "I had them put on a new roof that came out very nice and the Solar panels and end batteries 2 they installed is running my house all by itself."

Post-install support gaps. The complaint pattern is limited but includes reports of systems not producing as expected and difficulty getting follow-up responses on unresolved issues. Representative review excerpt: "Despite this, the loan funded after “final inspection,” so I’ve been making payments on a system that has never produced power."

Bottom line: Across 313 substantive reviews, SPARTAN HOME SERVICES earns a strong overall profile, with especially high marks for workmanship, sales clarity, and communication. The main softer spots are price and financing transparency, along with a smaller set of complaints about follow-up, timing, and post-install support.

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.
