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

How does Demand 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 Demand 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.

Demand Construction reviews: what customers say

An independent synthesis of published customer feedback, 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. Some describe clear explanations, helpful walkthroughs, and a non-pushy approach, while others report contract expectations and promises not matching the project outcome. The complaint pattern centers on unclear commitments, delayed delivery, and disputes over refunds or follow-through.Solar.com's composite of published customer feedback, not a customer quote

Contract and expectation complaints. Other reviewers report long delays after signing, promises that were not met, and frustration that the project did not align with what they say was discussed up front. Representative review excerpt: "It's been over six months since I signed a contract with them, and I still have no solar panels or Tesla Powerwall batteries installed -- despite paying them the majority..."

Helpful explanations. Some reviewers say the team took time to explain the process, answer questions, and provide information without pressure. Representative review excerpt: "he also took his time to explain everything to me and answered all my questions."

Honest and non-pushy. A few reviewers describe the sales interaction as honest, fair, and supportive during an unfamiliar purchase process. Representative review excerpt: "It was awesome to work with them they are honest in a industry that is hard to find that in"

Price & financing transparency

Price Transparency4.2/10

Feedback on pricing and financing trends negative. Reviewers more often describe refund disputes, billed amounts tied to unfinished or inactive systems, and confusion about what they owed than they describe clear cost guidance. A small amount of praise appears, but the dominant pattern is dissatisfaction with transparency and payment handling.Solar.com's composite of published customer feedback, not a customer quote

Refund and billing disputes. Several reviewers report requesting refunds or reimbursements and say they were still dealing with bills, deposits, or charges related to incomplete or non-working work. Representative review excerpt: "We have asked for a refund as per the termination clause in the contract but of course no communication from Demand Constuction."

Payment confusion after delays. Reviewers also describe paying for a system that was not yet installed or functioning, with some saying they continued to receive utility or financing charges during the delay. Representative review excerpt: "Now I'm still paying Edison and paying for a solar system that isn't even working."

Some initial cost guidance. One reviewer says they felt unsure about the cost and how to get started, which suggests at least some early-stage explanation was available. Representative review excerpt: "I was unsure of the cost and how to obtain solar."

Communication & coordination

Communication3.9/10

Communication is a major pain point in the review set. Some customers say the company was responsive and helpful, but many more describe repeated calls and emails without callbacks, unclear project ownership, and weak updates when problems arose. The recurring complaint is that customers had to chase the company for status, refunds, or next steps.Solar.com's composite of published customer feedback, not a customer quote

No response or follow-through. Many reviewers report calling and emailing repeatedly without getting replies, along with little explanation about delays, refunds, or project status. Representative review excerpt: "We have called and emailed the company several times but no one calls or emails us back."

Responsive for some projects. A few reviewers say the team responded quickly, stayed helpful, and guided them through the process. Representative review excerpt: "I needed solar for one of my properties and they were quick to respond and helpful."

Clear guidance in some cases. Some reviewers also describe patient communication and say staff helped explain the process in a way that made the project easier to follow. Representative review excerpt: "Special thanks to Juan and David for patiently walk me through the hole process, you made my life easier."

Timeline reliability

Timeline Reliability4.0/10

Timeline performance is viewed as unreliable overall. A few reviewers mention quick completion or smooth activation, but the larger pattern is extended delays, missed expectations, and projects that took far longer than promised. Complaints also mention slow permitting or inspection-related progress and periods where the system was not yet operational.Solar.com's composite of published customer feedback, not a customer quote

Extended delays and missed expectations. Other reviewers describe waiting months for installation, activation, or PTO, with some saying the project dragged far beyond the timeline they were given. Representative review excerpt: "It's been over six months since I signed a contract with them, and I still have no solar panels or Tesla Powerwall batteries installed -- despite paying them the majority..."

Some fast completions. A handful of reviewers say the timeline was efficient and that activation or utility setup happened soon after installation. Representative review excerpt: "Quick and efficient timeline with great communication Would recommend for others!!"

Smooth setup in a few cases. Some customers report that the system was fully set up shortly after installation and that the process moved along well. Representative review excerpt: "Less than 1 month after the installation, everything is set up with SDG&E and we hope to start seeing the lower bills."

Workmanship & site care

Workmanship6.0/10

Workmanship reviews lean somewhat positive, but there are still notable concerns. Several customers describe clean installs, attractive panel placement, and crews that handled roof-related issues well. At the same time, a smaller set of reviewers reports installation mistakes, roof damage concerns, or work that needed correction before final approval.Solar.com's composite of published customer feedback, not a customer quote

Installation mistakes reported. Other reviewers describe workmanship problems, including damage concerns and installs that needed follow-up corrections or additional inspection work. Representative review excerpt: "I did catch by camera one of their workers drilling holes in the porch roof while another one said "a little more to your left."

Clean-looking installs. Some reviewers say the crew did a clean job and that the finished roof layout looked good. Representative review excerpt: "The guys did a good and clean job and I'm very satisfied with the service provided from this company."

Roof and layout help. A few customers mention that the team helped work through roof conditions or placement needs during installation. Representative review excerpt: "They helped me figure out the roof situation since it was a flat room and needed some support."

Long-term support & performance

Long-Term Support6.1/10

Post-install feedback is mixed but slightly positive overall. Some reviewers say the finished work was solid and that service remained satisfactory after installation. However, most of the complaint evidence points to systems that were not operating as expected, slow support when issues came up, and unresolved follow-up on payments or reimbursements tied to system performance.Solar.com's composite of published customer feedback, not a customer quote

Operational and support issues. Other reviewers report systems that were not working properly, delayed appointments, and unresolved follow-up when performance problems appeared after funding or activation. Representative review excerpt: "Months later, I was still left with: A system that is NOT operational No follow-through from the contractor Financing still expecting payment for an incomplete job Zero ownership or urgency..."

Satisfied after completion. A few reviewers say they were happy with the service and the finished result after the job was done. Representative review excerpt: "The guys did a good and clean job and I'm very satisfied with the service provided from this company."

Good service from the team. Some customers describe the post-install experience in positive terms and say the team handled the job well overall. Representative review excerpt: "Thank you so much to the team at Sunny Sky Solar, I wouldn't recommend any other team to get the job done, at this amazing level of service."

Bottom line: Demand Construction’s review profile is mixed overall, with a Solar.com installer score of 5.3/10. The strongest criticism centers on communication, timeline reliability, and price or refund transparency, while workmanship and post-install performance receive somewhat better but still uneven feedback. Reviewers most often describe delays, weak follow-up, and payment-related frustration rather than a consistently smooth project experience.

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.
