The Verdict

California State Development has a severe follow-up problem that makes them too risky to hire. One homeowner spent two years chasing them for repairs after roof tiles were improperly installed during a solar project, causing interior water damage that the company never addressed despite hundreds of calls and emails. Another customer paid their down payment and first installment over a year ago and still has no panels on their roof and no refund. The core issue is post-installation abandonment. We found 11 reviews describing unreturned calls, unfulfilled promises, and unresolved system issues after payment cleared. Seven reviewers specifically warned that the company goes silent once they have your money. On the flip side, 13 reviews praised the initial sales process and competitive pricing, and 9 customers said their installations went smoothly with responsive project management. But those positive experiences cluster in 2021, while the complaints about ghosting span 2023-2024. When a company can't be reached to fix a disconnected panel or a leaking roof they damaged, the upfront savings become expensive.

If you value peace of mind over a competitive quote, skip this one. The pattern is clear: responsive during the sale, unreachable after installation. Even customers who praised their systems describe months of silence when issues arose. You're gambling that nothing will go wrong, and solar projects rarely go perfectly.

3 Stories That Stood Out

1. James O.
Yelp | Sep 27, 2024 |

James began a combined solar-and-roof project about two years ago and spent that time chasing the contractor over shoddy roofing work and resulting interior damage. After installers cracked many roof tiles during the solar fit, the roofing crew (Grand Canyon) came back to replace tiles but did such a poor job that rain leaked through and ruined sections of the ceiling. He logged hundreds of calls and emails to California State Development to get the defects fixed, but the company repeatedly ignored phone and email contact, leaving him waiting months for any follow-up. The solar panel install itself matched his requests and produced real energy savings, and when a panel later showed as disconnected the panel company honored its warranty; still, he had to find a certified solar contractor to replace the failed part because California State Development would not engage. He gave the company many chances over two years before posting this one-star experience. The detail that lingers: solid solar hardware paired with unreliable contracting and unresponsive customer service that left him arranging repairs and covering damage resolution through other contractors while still saving on his电账

2. Malvin P.
Yelp | Jun 5, 2023 |

Malvin P. hired the company to install solar panels on his home more than a year ago, paying an initial down payment plus a first installment. Instead of getting a system on his roof, he waited through months of empty promises while the panels never arrived and no refund was issued. The situation worsened when the company misled the Contractors Board by telling the assigned representative that his complaint had been settled—something that couldn’t be farther from the truth. He has been patient and repeatedly asked for his money back, but the company has failed to respond. Concluding that the firm may not handle business in San Francisco County as effectively as in Southern California, he is now preparing for arbitration after more than a year with no installation and no refund.

3. Kailani N.
Yelp | Sep 12, 2023 |

Kailani initially connected with a salesperson named Vloddy and felt confident moving forward with a residential solar panel installation. After he left the company, contact evaporated: for the second half of the project she couldn’t reach anyone to finish work or repair damage from the installation. More than a year has passed with little to no follow-up, no fulfillment of a promised Amazon gift card, and repeated unresponsiveness. She involved the city, which flagged the contractor’s unprofessional behavior, and ended up having paid under contract while critical service and repairs remain undone. The lasting image is a paid-for system with unresolved damage and no reliable post-install support.

What You Can Expect

01

1. Sebastian N.
Yelp | Dec 8, 2023 |

Sebastian N. had solar panels installed on his home and ended up with a system he expects will shave a significant amount from his energy bills over the years. He ran into a few hiccups along the way, but his agent Luis stayed involved throughout the process, guiding the project to completion and handling the details so Sebastian didn’t have to worry. The clear results were lower future bills and the satisfaction of doing something good for the planet — and what stuck with him most was Luis’s hands-on support during the setbacks.

2. Brian R.
Yelp | Nov 2, 2023 |

Brian R. hired California State Development to outfit his home with solar and found they delivered on their promises. The installation came at a competitive price and the crew did solid, tidy work. Luis stayed hands-on throughout the project, making sure every task was finished as agreed, and because of that oversight he ended up with a complete, well-executed installation and genuine satisfaction. The memorable detail: the personal follow-through from Luis turned a good price and good workmanship into a worry-free outcome.

1. Mark H.
Yelp | Feb 18, 2022 |

When Mark decided to put solar on his home, he picked Cal State Dev and found their team consistently helpful, informative and friendly. He experienced a straightforward process: the company walked him from quote through financing to the actual install, supplying the information he needed at each step. Pricing matched his expectations, the crew worked efficiently, and the project moved smoothly once the utility completed its part — the installers finished the system in a single day. The thing that stood out most was the clear, end-to-end guidance combined with a one-day install after the power company’s sign-off.

2. Jeremy W.
Yelp | Oct 6, 2021 |

Jeremy W. hired Cal State Development to replace his roof and install solar panels on his home, and their bid stood out as one of the most competitive for the scope of work. He appreciated the thoughtful design and upfront planning that shaped the project from the start, and the permitting cleared much faster than he expected—remarkably so given it happened over the summer. The crew kept him informed at every step, explaining material options and tracking progress, and when issues cropped up they responded quickly and implemented fixes. He especially valued having a single, accessible project manager who answered questions and kept the job moving; the combination of unexpectedly fast permitting and a reliable point of contact is what stuck with him most.

1. Andrew B.
Yelp | Jan 11, 2024 |

Andrew had 13 solar panels fitted to his shingle roof; the system has been producing power and trimming his electricity bills. He drove a hard bargain during the process and insisted on bundling an EV car charger into the project — with the charger included he ended up with the best deal he found after shopping around. He urges other buyers to ask about adding a car charger when they speak with sales, and if they pursue one, to request Luis and give Andrew’s name so the referral gets credited.

3. Dequoy W.
Yelp | Nov 3, 2025 |

Dequoy W. had a newly installed residential solar system that began failing almost immediately; he discovered faulty equipment and a setup that kept going offline. He watched the system’s app show more energy produced than used, yet Edison billed him an extra $2,500 for what the utility called excessive consumption. Repeated attempts to reach the installer went unanswered and promised fixes never arrived. Frustrated, he brought in an independent third party, hired a lawyer, and filed a complaint with the Better Business Bureau to try to force a resolution. He observed the company undercut competitors on price but ultimately paid far more in time, fees, and stress—the detail that sticks is the alarming mismatch between the system’s monitoring and the utility billing.
