How does Plug It In Systems 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 Plug It In Systems 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.

Plug It In Systems 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 Integrity6.9/10

Reviewers generally describe the sales process as clear, helpful, and low-pressure. The available evidence is entirely positive in this category, with no mixed or complaint examples in the sampled reviews.Solar.com's composite of published customer feedback, not a customer quote

Clear, low-pressure sales process. Reviewers say the sales team answered questions directly, explained the process well, and did not pressure them into signing. Several also describe the proposal stage as straightforward. Representative review excerpt: "I truly appreciated his honesty, professionalism, and willingness to answer all of my questions without any pressure."

Helpful before and after signing. Customers report that communication stayed useful through installation and follow-up, with expectations set clearly from the start. The overall pattern is a smooth handoff into the project phase. Representative review excerpt: "They're straightforward with their process and very helpful before, during and after installation."

Professional presentation. Some reviewers note that the initial sales experience felt organized and on time, with expectations aligned to the finished work. They also describe the team as attentive to questions and details. Representative review excerpt: "The sales process was not high pressure, they were on time, they cleaned up, they helped me set up my app, i could not be more satisfied."

Price & financing transparency

Price Transparency6.6/10

Reviewers mostly describe pricing, financing, and rebate handling as clear and workable, but there is one complaint about the timing of financing-related follow-through. The category is positive overall, though less strong than the company’s best-rated areas.Solar.com's composite of published customer feedback, not a customer quote

Helpful with pricing and incentives. Reviewers say the team was transparent about pricing and handled rebate or incentive timing support over an extended period. Some mention that the company kept working on paperwork and timing after installation. Representative review excerpt: "They worked withe me for over a year after the installation to help me get the rebate for the battery."

Rebate and bill outcomes. A number of customers describe receiving credits or seeing billing benefits after the system was online. These comments suggest the pricing conversation often extended into post-install value tracking. Representative review excerpt: "I have received my latest SCE bills and we are selling power back to them (albeit for Pennie’s on the dollar) but the latest bill showed a credit already."

Financing follow-through concern. One reviewer says progress slowed after loan funds were released and felt the project was deprioritized at that stage. This is the main complaint pattern in the category sample. Representative review excerpt: "Seems to me that once you sign off for your loan money to be released they put you on the back burner which I did on 01/04/2025."

Communication & coordination

Communication7.5/10

Most reviewers describe strong responsiveness, clear updates, and good project ownership across the solar process. There is one complaint in the sample about needing to repeatedly contact the company to get updates or schedule the next step, but it appears uncommon in the reviewed set.Solar.com's composite of published customer feedback, not a customer quote

Clear, responsive updates. Reviewers frequently say emails, texts, and follow-ups were timely and easy to understand. Many describe the team as staying on top of details from start to finish. Representative review excerpt: "From start to finish, their communication was outstanding—every email and text was crystal clear, and they were on top of every detail."

Project ownership and handoffs. Customers report that project managers followed through on questions and coordinated well across installation stages. Several mention feeling supported through the process rather than left to chase information. Representative review excerpt: "My Project Manager Isaac followed up on all my questions, and the team that came to install the panels did great work, even removing an old electrical piece on the..."

Occasional chase for updates. One reviewer says they had to repeatedly call or email to learn why delays were happening or to schedule the next step. That suggests a rare but real coordination gap in the sample. Representative review excerpt: "Every step of the way I’ve had to constantly call/email them to find out why there’s been a delay or to schedule the next step."

Timeline reliability

Timeline Reliability7.0/10

Reviewers mostly describe installation and activation as timely, with several noting quick progress through inspection and certification. The sample also includes one report of a delay tied to PTO scheduling, so timing appears generally reliable but not perfect.Solar.com's composite of published customer feedback, not a customer quote

Fast completion for many jobs. Several reviewers say their systems were installed and certified within a relatively short period after signing. These accounts point to solid schedule execution in a large share of the sample. Representative review excerpt: "Entire system (including powerwall, panels, conduit and necessary alarms, panel upgrades and cosmetic touches) was installed and certified less than 2 months after signing the initial contract."

Inspection and startup momentum. Customers report that the team worked to pass inspection quickly and get systems up and running without unnecessary delay. Some also describe the final installation as happening on schedule. Representative review excerpt: "The solar team went above and beyond in making sure we passed inspection and wasted no time to get us up and running."

PTO scheduling delay. One reviewer says the company did not know when the utility visit was scheduled, which created another delay before turn-on. This is the main timeline complaint appearing in the sampled reviews. Representative review excerpt: "Of course, they were unaware of when DWP was scheduled to come out and issue me a PTO so now there’s another scheduling delay with turning on my system."

Workmanship & site care

Workmanship7.6/10

Reviewers consistently describe the installation crews as professional, careful, and respectful of the property. The sampled reviews for this category are entirely positive, with no complaint examples included in the evidence set.Solar.com's composite of published customer feedback, not a customer quote

Clean and efficient crews. Customers say the roof and installation crews were friendly, efficient, and kept the work area clean. Cleanup and site respect are recurring themes in the reviews. Representative review excerpt: "The Roof workers were friendly, efficient & kept the area clean."

Careful installation details. Reviewers mention that the team handled conduit, panel work, and cosmetic touches carefully and professionally. Some note that the work looked detailed and well finished. Representative review excerpt: "You can tell they take pride in their work--every detail was handled carefully and professionally."

Responsive to related site work. A few customers describe the company returning to complete or redo panel work after other roof-related tasks were finished. That suggests coordination around the job site was handled with attention. Representative review excerpt: "Once the foam roofer filled in around those footings and finished the rest of the work he needed to do, Plug It In came back and reinstalled my panels with..."

Long-term support & performance

Long-Term Support7.5/10

Most reviewers describe good post-install support, including help with monitoring, repairs, and system follow-through after turn-on. There is one complaint about a PTO-related delay affecting activation, but the broader pattern is positive.Solar.com's composite of published customer feedback, not a customer quote

Post-install help and repairs. Reviewers say the company helped when system communications or other issues needed attention after installation. Some describe direct repair support rather than being left to troubleshoot alone. Representative review excerpt: "When an issue with my solar system communications needed an expert to repair, Plug it in took care of it."

Ongoing support over time. A few customers mention long-running relationships and continued satisfaction with recommended technicians or staff. This points to continued support beyond the original install date. Representative review excerpt: "I have worked with Keith for over 12 years and have always been completely satisfied with whomever he r e c o m m e n d e d ."

Activation delay affected performance start. One reviewer reports that a PTO timing issue delayed system turn-on, which slowed the point at which the system could begin operating as expected. This appears to be an isolated complaint in the sample. Representative review excerpt: "Of course, they were unaware of when DWP was scheduled to come out and issue me a PTO so now there’s another scheduling delay with turning on my system."

Bottom line: PLUG IT IN SYSTEMS earns an 8.0/10 Solar.com installer score based on mostly positive Google reviews and 109 substantive reviews analyzed. The strongest themes are workmanship, communication, and generally solid project coordination, while price/financing and activation timing show a few isolated concerns. Complaints are rare in most categories, but reviewers do occasionally mention financing follow-through or utility-related timing 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.
