How does Sun Diego Solar Construction 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 Sun Diego Solar Construction 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.

Sun Diego Solar Construction 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 Integrity7.1/10

Reviewers are generally positive about the sales process, describing knowledgeable, straightforward communication and proposals that felt clear and easy to work with. A small number of reviews raise concerns about system sizing and whether expectations matched the eventual output, so the category is positive overall but not spotless.Solar.com's composite of published customer feedback, not a customer quote

Straightforward, knowledgeable sales. Reviewers often say the sales team was easy to work with, knowledgeable, and clear about the project details. Several also describe the proposal process as accommodating and low-pressure. Representative review excerpt: "I decided to go with Rick from Sun Diego Solar, I found him to be very knowledgeable and straight forward."

Clear expectations for some customers. Some reviewers mention that the company handled scheduling and project details smoothly, including around new construction work. That suggests the proposal and early planning stage was organized for many customers. Representative review excerpt: "They were very easy to work with and accommodating when it came to scheduling around my new construction project."

Sizing expectations not always met. A small set of reviewers report concerns that the system was not sized as expected, which affected how the project performed after install. Those complaints make this a mildly mixed area rather than purely positive. Representative review excerpt: "My main concern is that they didn't size the system correctly and we now receive a bill from SDG&E for power consumption not supplied by solar."

Price & financing transparency

Price Transparency6.7/10

Reviews are mostly favorable about pricing conversations and the clarity of cost discussions, with some customers saying they felt informed and comfortable moving forward. The main caution is that a small number of reviewers describe concerns tied to system sizing and resulting bills, which makes this a positive-to-mixed category.Solar.com's composite of published customer feedback, not a customer quote

Pricing felt understandable. Several reviewers describe the cost conversation as clear enough that they felt comfortable with the decision. Some also mention being able to discuss solar questions directly and get straightforward answers. Representative review excerpt: "In the end, it came down to the personal referral and the fact that Rick was always available to answer any questions and chat about solar."

Efficient delivery and installation value. A number of customers describe the work as efficient and professional, which suggests they felt the project delivered good value for the price. Others mention the install was handled cleanly and without obvious disruption. Representative review excerpt: "They work quickly and efficiently and we’re professional the whole time."

Watch-out on post-install costs. A small number of reviewers say the system did not produce as expected, leading to ongoing utility bills they did not anticipate. That is the main transparency concern reflected in the reviews. Representative review excerpt: "My main concern is that they didn't size the system correctly and we now receive a bill from SDG&E for power consumption not supplied by solar."

Communication & coordination

Communication7.4/10

Reviewers consistently describe responsive, attentive communication and smooth coordination across the project. Across the available feedback, there are no notable complaint patterns in this category, and customers often mention feeling supported through scheduling and follow-through.Solar.com's composite of published customer feedback, not a customer quote

Responsive and attentive team. Reviewers frequently praise customer service and say the team was attentive throughout the process. Some specifically note that questions were answered promptly and that the company stayed available when needed. Representative review excerpt: "Thank you RIck and your company for your amazing customer service and attentiveness, we will be recommending your company to everyone!!!!"

Good handoffs and scheduling. Customers describe the company as easy to work with and accommodating around scheduling needs. That includes projects that required coordination with other construction activity. Representative review excerpt: "They were very easy to work with and accommodating when it came to scheduling around my new construction project."

Team communication on the job. Some reviewers say the crew worked well together and that communication remained solid during install. The reviews suggest project ownership was handled smoothly for many customers. Representative review excerpt: "Install went well, and my wife said the crew worked well together."

Timeline reliability

Timeline Reliability7.1/10

Reviews point to dependable scheduling and timely completion in most cases. Customers commonly say the company did what it said it would and kept projects moving without major delays in the reviewed feedback.Solar.com's composite of published customer feedback, not a customer quote

Promised timing met. Reviewers say the company generally did what it said it would, when it said it would. That pattern suggests dependable follow-through on the schedule. Representative review excerpt: "I liked the fact that they did everything they said they would, when they said they would."

Timely install process. Some customers describe the work as efficient and completed in a timely manner. Others note that the team communicated well throughout the process, which helped keep the project on track. Representative review excerpt: "Nice guys; they communicated, were efficient and did the job in a timely manner."

Flexible around scheduling needs. A few reviewers mention that the company was accommodating when project timing had to line up with new construction or other home work. That flexibility appears to have helped with coordination and activation timing. Representative review excerpt: "They were very easy to work with and accommodating when it came to scheduling around my new construction project."

Workmanship & site care

Workmanship7.1/10

Most reviewers describe the crews as professional, careful, and respectful of the property. A few complaints do appear around site care and installation mistakes, so the category is generally positive but carries some caution on workmanship consistency.Solar.com's composite of published customer feedback, not a customer quote

Professional crews and clean work. Many reviewers say the crew worked well together and completed the installation neatly. Several also mention that the company kept the job organized and professional on site. Representative review excerpt: "Install went well, and my wife said the crew worked well together."

Property care and cleanup noted. Customers describe the team as careful with the home and attentive to damage or cleanup concerns. Some say the property looked tidy after the work was finished. Representative review excerpt: "They pay attention to details and even made me aware if something was damaged on my property during the project and told me they would be repairing it (I would..."

Isolated site-care complaints. A small number of reviewers report concerns about respect for the home and property during the job, including issues that required follow-up. That makes workmanship a solid but not flawless area. Representative review excerpt: "Tell your workers to be respectful of other people's homes and property when working on clients homes, blocking utilities is such a lack of self awareness and apathetic approach to..."

Long-term support & performance

Long-Term Support7.4/10

Post-install feedback is mostly positive, with reviewers describing helpful support, monitoring knowledge, and good system performance after turn-on. There is one notable complaint about system sizing and resulting utility bills, but it is outweighed by the broader pattern of satisfied follow-up experiences.Solar.com's composite of published customer feedback, not a customer quote

Helpful after-install support. Reviewers say the company remained responsive after the project was complete and that support continued beyond the initial install. Some mention willingness to be a first call for future home service needs. Representative review excerpt: "Thank you RIck and your company for your amazing customer service and attentiveness, we will be recommending your company to everyone!!!!"

System knowledge and monitoring. Customers describe the team as knowledgeable about battery storage, monitoring, and related system questions. That suggests a decent level of post-install support expertise. Representative review excerpt: "*Knowledgeable about various systems, battery storage, and monitoring the panels."

One performance concern. A small number of reviewers report that the system did not cover all expected usage, which led to ongoing utility bills. This is the main long-term performance caution reflected in the reviews. Representative review excerpt: "My main concern is that they didn't size the system correctly and we now receive a bill from SDG&E for power consumption not supplied by solar."

Bottom line: Across 28 substantive reviews, SUN DIEGO SOLAR CONSTRUCTION earns a generally positive profile, with especially consistent praise for communication, scheduling, and post-install responsiveness. The main caution areas are pricing transparency, workmanship consistency, and a small number of complaints about system sizing and resulting bills, while complaints overall appear limited in the reviewed sample.

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.
