How does Next Door Home Upgrades 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 Next Door Home Upgrades 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.

Next Door Home Upgrades 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 Integrity8.2/10

Reviewers mostly describe the sales process as clear, thorough, and low-pressure. They frequently say expectations, options, and incentive timing were explained carefully, with only a rare complaint in this category.Solar.com's composite of published customer feedback, not a customer quote

Clear explanations. Reviewers say the team took time to walk through options, the process, and what to expect, which helped set realistic expectations before work began. Representative review excerpt: "They took the time to answer every question, explain all of our options clearly, and never made us feel pressured."

Helpful guidance. Customers report that program details and incentive timing were explained in a way that made the proposal easier to understand. Representative review excerpt: "He explained the process, what our expectations could be, and the various programs and incentives we would be eligible for."

Rare complaint pattern. A small number of reviews describe problems with follow-through after the sale, including one report that work was not completed as understood. Representative review excerpt: "After three months of being led under the impression they were on top of this with the manufacturer, I found out that nothing was done."

Price & financing transparency

Price Transparency7.5/10

Feedback on pricing and financing is mostly positive, with reviewers describing reasonable pricing and smooth loan setup. The review set also includes one complaint and a few comments that touch on financing or project-related issues, so this category is solid but not spotless.Solar.com's composite of published customer feedback, not a customer quote

Reasonable pricing. Reviewers say pricing was reasonable and that the value felt fair for the work and products delivered. Representative review excerpt: "Nextdoor Solar provides excellent worksmanship, attentive customer service and durable solar products at reasonable prices."

Financing support. Customers report that partner-lender financing was handled smoothly and that the approval and setup process felt hassle-free. Representative review excerpt: "Another major plus: Next Door Home Upgrades helped me secure a loan through one of their partner lenders, and the entire approval and setup process was smooth and hassle‑free."

Watch-out. There is also a complaint in the review set tied to a worksite incident, so the category is not entirely free of negative feedback. Representative review excerpt: "On the first day of their work my wife said someone threw a piece of metal off the roof and almost hit her."

Communication & coordination

Communication8.7/10

Communication is one of the strongest themes in the review corpus. Reviewers consistently say the team was responsive, coordinated handoffs well, and kept projects moving with clear updates; only a couple of complaints appear in the data.Solar.com's composite of published customer feedback, not a customer quote

Responsive support. Reviewers frequently say questions were answered quickly and that the team stayed engaged through installation and follow-up. Representative review excerpt: "They were very responsive to any questions that pertained to the installation and the work was performed in an extremely timely fashion."

Smooth coordination. Customers report that scheduling, permitting, and project handoffs were handled with strong organization and steady communication. Representative review excerpt: "After we signed, Josh handled all the hoops of the Burbank permitting process flawlessly and with great communication."

Minor complaint pattern. A small number of reviews describe communication breakdowns tied to broader project issues, so the category is not perfect despite the strong overall pattern. Representative review excerpt: "On the first day of their work my wife said someone threw a piece of metal off the roof and almost hit her."

Timeline reliability

Timeline Reliability8.2/10

Most reviewers say timelines were managed well, with work completed as promised and permits or activation steps handled efficiently. There is one mixed review and one complaint in the data, so timing is generally reliable but occasional delays still show up.Solar.com's composite of published customer feedback, not a customer quote

Delivered as promised. Reviewers say jobs were completed on schedule or close to the promised window, even when timing was tight. Representative review excerpt: "And even though there was only about a month left before the end of the year, he assured me he could get the job done and he absolutely delivered."

Permit and PTO handling. Customers report that the team helped navigate inspection and permission-to-operate steps, reducing the burden on the homeowner. Representative review excerpt: "After installation, Josh again handled all the hoops of the inspection and Permission To Operate paperwork beautifully."

Occasional delays. A small number of reviews mention waiting on inspection or encountering activation-related delays, showing that timing can still depend on outside agencies. Representative review excerpt: "I had to wait a month for LADWP to finish inspection on Jan 16, 2026 to turn system on."

Workmanship & site care

Workmanship8.8/10

Reviewers overwhelmingly describe the installation crew as professional, careful, and tidy. Most feedback praises the quality of the work and site cleanup, while a very small number of complaints mention roof or tile damage concerns.Solar.com's composite of published customer feedback, not a customer quote

Rare workmanship complaint. A small number of reviews report damage or installation-related issues, including concerns about tiles and rooftop debris. Representative review excerpt: "On the first day of their work my wife said someone threw a piece of metal off the roof and almost hit her."

Long-term support & performance

Long-Term Support8.9/10

Post-install support is a major strength in the review set. Reviewers say systems perform as expected, monitoring works well, and follow-up service is responsive, with no complaints appearing in this category.Solar.com's composite of published customer feedback, not a customer quote

Strong post-install follow-up. Customers report that the team checked back after installation and made adjustments when needed to support ongoing system performance. Representative review excerpt: "He followed up with us after a year to ensure our system was performing as promised, and even made an adjustment to help us save even more money."

Monitoring and performance. Reviewers say monitoring features and battery backup provide confidence in how the system is operating after turn-on. Representative review excerpt: "I chose Enphase microinverters, which allow me to monitor each panel individually through the Enphase app -- a huge advantage over systems that only show total production."

Ongoing service confidence. Several reviewers say they would call the company again for maintenance or upgrades, reflecting positive experiences after the initial install. Representative review excerpt: "After today, if my system needs and type of maintenance or upgrade, my first call with be to Next Door Home Upgrades."

Bottom line: Across 164 substantive reviews, NEXT DOOR HOME UPGRADES is described most often as responsive, organized, and careful with installation and follow-up.

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.
