How does Green Day Power 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 Day Power 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 Day Power 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 Integrity5.3/10

Reviewers give a mixed picture of the sales experience. Positive comments focus on clear explanations, patience with questions, and reps who were described as knowledgeable and not pushy, while complaints center on overselling, contract expectations, and assurances that did not match later outcomes.Solar.com's composite of published customer feedback, not a customer quote

Clear, patient explanations. Some reviewers say the sales team took time to answer questions, explain the proposal, and avoid pressure during the decision process. Representative review excerpt: "Most others would just stop talking to you if you asked too many questions, or didn't have all the answers, but not Jacob, he really knows what he is talking..."

Pressure and oversell concerns. Other reviewers describe sales conversations as overly aggressive or say the proposal included more equipment or terms than they expected. Representative review excerpt: "The person that came out to give me a quote, tried to oversell me a 22kW generator which I didn't need for the size of my home."

Contract expectations not matching later outcome. A recurring complaint is that some customers say they were told one thing up front, then later found the transferability or contract details were different than expected. Representative review excerpt: "We were assured that our solar loan was fully transferable in case we wanted to move out of our homeZ when we went to sell they wouldn't let us transfer..."

Price & financing transparency

Price Transparency4.1/10

This category leans negative, with complaints about deposits, financing terms, surprise costs, and payout or refund issues showing up often. Positive reviews do mention clear estimates and favorable pricing or rates, but they are outnumbered by reports of unclear or changing financial expectations.Solar.com's composite of published customer feedback, not a customer quote

Deposit and financing confusion. Several reviewers report problems around deposits, payment timing, and financing details that they say were not explained clearly at the start. Representative review excerpt: "It wasn't untill accounting reached out to me and asked for the deposit that, he waswas contacted and turned it in."

Unexpected costs and payment burden. Other complaints describe higher-than-expected project costs, ongoing payments, or systems that customers felt were costing them money after installation. Representative review excerpt: "On top of that we have now made 5 payments for this system that is costing me money."

Clear estimates when things go well. Some reviewers describe the pricing discussion as straightforward, with clear estimates and time spent explaining the financial side of the project. Representative review excerpt: "Green Day Power provides clear estimates for installation and maintenance costs, which is essential for anyone considering solar energy solutions."

Communication & coordination

Communication4.3/10

Reviews on communication and coordination are mixed to negative. Some customers report regular check-ins, same-day follow-up, and smooth handoffs, while many others say they had trouble getting updates, reaching staff, or figuring out who owned the next step in the project.Solar.com's composite of published customer feedback, not a customer quote

Hard to reach or slow to respond. A common complaint is that calls and emails went unanswered, leaving customers waiting for basic status updates or next-step scheduling. Representative review excerpt: "Don't respond to emails or answer calls."

Project ownership felt unclear. Some reviewers say they had to manage the project themselves because they were not confident the internal team was coordinating well with city staff or crews. Representative review excerpt: "I basically had to manage the project myself as their project management team was inept at communicating with the city and their site crews."

Regular updates when service is strong. Positive reviews say the team kept customers updated, followed up promptly, and stayed engaged throughout the project. Representative review excerpt: "GDP comes on time, does regular check ins and follow ups and keep you updated throughout the entire process."

Timeline reliability

Timeline Reliability4.7/10

Timeline feedback is uneven. A number of reviewers describe a smooth install-to-activation process, but many others report long delays around inspections, permitting, and utility-related steps, plus difficulty getting the project closed out.Solar.com's composite of published customer feedback, not a customer quote

Inspection delays. A repeated complaint is that inspections or final approvals took much longer than expected, sometimes with little explanation when corrections were needed. Representative review excerpt: "Took them FOUR MONTHS to get the inspection scheduled and then went radio silent after there were corrections needed."

Permitting and activation follow-through issues. Other reviewers say the project stalled during permitting or final activation and that they struggled to get responses while waiting for closure. Representative review excerpt: "I'm now trying to get th to schedule a final inspection but again they don't answer calls or respond to emails."

Smooth turns when the project stays on track. Some reviewers say the installation, city inspection, and utility switchover moved smoothly once the work was underway. Representative review excerpt: "The install, the city inspection and PGNE switchover were very smooth."

Workmanship & site care

Workmanship5.7/10

Workmanship and site care trends somewhat positive overall, with several reviewers praising professional crews and tidy work. Still, there are meaningful complaints about incomplete jobs, roof damage, and projects that remained unresolved for long periods.Solar.com's composite of published customer feedback, not a customer quote

Professional crews and cleanup. Positive reviews describe installers as professional, knowledgeable, friendly, and careful about cleaning up at the end of the day. Representative review excerpt: "All the Green Day crews who worked on the project were professional, knowledgeable, friendly, and cleaned up at the end of each workday."

Roof and site damage concerns. Some reviewers report damage or leaks after installation and say the workmanship did not hold up the way they expected. Representative review excerpt: "Solar panels are expensive and if they do not install them properly it can caused damage on your roof and can caused leaks,just like what happened to us."

Incomplete or unresolved installs. Other complaints say the project remained unfinished or had enough issues that the system was still not operating properly long after the original install date. Representative review excerpt: "A year and a half later and we still don't have working solar panels due to dozens of issues with Green Day and Axia."

Long-term support & performance

Long-Term Support5.8/10

Post-install feedback is mixed. Some customers report continued follow-up care and support, but many others describe performance shortfalls, warranty questions, or difficulty getting help after the system was turned on.Solar.com's composite of published customer feedback, not a customer quote

Performance below expectations. Some complaints say the system did not generate as much power as expected or that customers were still dealing with unresolved performance problems after installation. Representative review excerpt: "There are two things Green Day could do to improve this rating: 1- Add more panels so the system generates the amount of power I paid for (needs about 25%..."

Service and warranty follow-up gaps. Other reviewers report difficulty getting warranty or service help, including delays in response and uncertainty about who would handle repairs. Representative review excerpt: "A company called Energy Aid has taken over for Green Day Power they will do the warranty work, I think parts are covered but the labor is not at I..."

Ongoing support can be strong. A few reviewers say they received continued follow-up care after purchase and felt supported after the sale. Representative review excerpt: "I purchased a Generac standby generator last year from Green Day Power and cannot say enough about the continued follow up care and support."

Bottom line: Green Day Power’s review profile is mixed overall, with strengths in some sales conversations, crew professionalism, and occasional smooth project completion. The main concerns are communication, price and financing clarity, and delays around inspections, permitting, or post-install support. The combined score reflects a service that has clear positive experiences but also a substantial number of complaints across multiple stages of the project.

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.
