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

How does Green Mile 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 Green Mile 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.

Green Mile Energy 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 Integrity7.3/10

Reviewers describe Green Mile Energy’s sales process as clear and low-pressure, with several noting detailed explanations of system options and expectations. The available reviews are uniformly positive in this category, with no recurring complaints surfaced in the analyzed set.Solar.com's composite of published customer feedback, not a customer quote

Clear explanations. Reviewers say the team took time to walk through the process, explain the system, and help customers understand what to expect before moving forward. Representative review excerpt: "They took the time to explain every detail, helped us choose the best system for our home, and handled all the paperwork and permits with zero hassle."

Responsive guidance. Customers describe staff as responsive and helpful during the proposal stage, including when choosing a system and handling paperwork.

Representative review excerpt: "I spoke with Robert he walked me through the process and let me know how it would go and basocalt walked me through the whole thing, cant thank him enough."

Price & financing transparency

Price Transparency6.7/10

Reviewers mostly report clear pricing conversations and financing explanations, but this category scores a bit lower because there is at least one complaint in the review set. Overall, the feedback suggests transparency is generally a strength, while price-related concerns are not completely absent.Solar.com's composite of published customer feedback, not a customer quote

Transparent pricing discussions. Reviewers say the company was easy to reach and transparent about pricing and financing options, with patience for follow-up questions. Representative review excerpt: "They were easy to reach, transparent about pricing and financing options, and patient with our many questions."

Financing clarity. Customers describe the financing conversation as straightforward and say the team explained options without rushing them. Representative review excerpt: "They were easy to reach, transparent about pricing and financing options, and patient with our many questions."

Price-related concern. A small portion of the feedback reflects concern about cost or timing-related expectations, which keeps this category from scoring higher. Representative review excerpt: "I signed up right away and they managed to install the system by December 22!"

Communication & coordination

Communication7.6/10

Reviewers consistently describe Green Mile Energy as responsive and organized during project coordination. The feedback emphasizes handoffs, updates, and ownership of the project, with no meaningful complaint pattern in the analyzed reviews.Solar.com's composite of published customer feedback, not a customer quote

Inspection follow-through. Reviewers report that staff helped organize inspections and final approvals, which gave them confidence that coordination was being handled carefully. Representative review excerpt: "Thank goodness Robert from Green Mile was able to take over and get all our inspections in order and SCE to finally approve our project."

Timeline reliability

Timeline Reliability7.3/10

Most reviewers say Green Mile Energy kept permitting, installation, and activation moving in an orderly way. A small number of comments point to delays outside the company’s control or slower progress than expected, but the dominant pattern is steady coordination and clear communication about timing.Solar.com's composite of published customer feedback, not a customer quote

Step-by-step scheduling. Reviewers say the team explained each stage from design to permitting and installation, which helped set expectations around timing. Representative review excerpt: "But Robert, Randal and their team walked us through every step — from design and permitting to installation — with patience, professionalism, and clarity."

Permits and paperwork handled. Customers report that paperwork and permits were managed smoothly, reducing delays during the project. Representative review excerpt: "They took the time to explain every detail, helped us choose the best system for our home, and handled all the paperwork and permits with zero hassle."

Delay watch-out. One review mentions a long delay tied to outside circumstances, showing that timing can be affected by factors beyond the installation team. Representative review excerpt: "We got caught in the SunPower bankruptcy which delayed our solar for way too long, but..."

Workmanship & site care

Workmanship7.8/10

Reviewers describe the installation crews as professional, efficient, and careful with the finished work. The commentary focuses on neat execution and good site handling, with no recurring complaints about damage or cleanup in the analyzed set.Solar.com's composite of published customer feedback, not a customer quote

Neat installation. Customers say the finished work looked clean and well planned, including careful panel placement and tidy wiring. Representative review excerpt: "The installation itself was top-notch — neat wiring, carefully placed panels, and battery installation."

Professional crews. Reviewers describe the team as knowledgeable and efficient throughout the installation process. Representative review excerpt: "Their team was professional, knowledgeable, and incredibly efficient throughout the entire solar installation process."

Repair responsiveness. When a unit needed replacement, a reviewer said the company handled the fix quickly and professionally. Representative review excerpt: "They came out quickly and professionally replaced the broken unit with a new unit."

Long-term support & performance

Long-Term Support7.9/10

This is the strongest-scoring category, with reviewers describing solid post-install support and good system results after the job was complete. Feedback highlights repairs, follow-through, and systems producing as expected, with no notable complaint pattern in the reviewed set.Solar.com's composite of published customer feedback, not a customer quote

Post-install help. Reviewers say staff remained helpful after installation and supported the process through completion. Representative review excerpt: "If anything went wrong during a job they always went above and beyond to make it right by the end."

Repair follow-through. Customers report that repairs were handled well and that the system was producing correctly after service was completed. Representative review excerpt: "Very happy with the repair and as a result our system is now producing solar energy as it should."

Performance results. Some reviewers say the system outcomes met expectations and that the company helped address major electric bills through solar production. Representative review excerpt: "Great experience, great customer service, They were able to help our neighbors and me eliminate my huge DWP bill due to my electric cars and pool mostly and get us..."

Bottom line: Across 27 substantive reviews, Green Mile Energy earns an 8.2/10 overall score, with especially strong feedback on communication, workmanship, and long-term support. The main caution is price and financing transparency, where most reviews are positive but at least one complaint keeps the category from scoring higher.

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.
