The Verdict

Sun Diego Solar offers competitive pricing and solid installation work, but sizing mistakes have cost some customers thousands. We found 13 reviewers who praised the crew's workmanship without a single complaint about install quality. One homeowner hired them three separate times for solar, EV charger, and pool electrical work, and felt comfortable leaving her home unlocked while the crew worked. The pricing stands out. Multiple reviewers compared quotes and chose Sun Diego because the owner's low overhead beat corporate installers by thousands for identical equipment. But two customers report the same frustrating outcome: they provided their utility bills, the system was undersized, and they now pay SDG&E every month despite having unused roof space. When they asked the company to fix it, they were quoted $5,000 for the additional panels. One reviewer who avoided this trap recommends oversizing your system by 5 to 10 percent from the start, since you're no longer going to cringe when summer bills arrive.

If you're comfortable double-checking the system size yourself and can verify the proposal matches your actual usage, Sun Diego's pricing and installation quality make them a solid pick. But if you expect the installer to get the sizing right without your oversight, the risk of an expensive correction isn't worth the upfront savings.

3 Stories That Stood Out

1. GGG
Google | Apr 8, 2025 |

GGG had Sun Diego Solar replace the old panels on a modest home a couple years ago and quickly discovered the new array was undersized — they now receive SDG&E bills for power the system doesn't cover, something that never happened before the upgrade. They had handed the installer an old bill showing actual usage, yet the company still installed a smaller system and left visible empty space on the racking where additional modules would fit. When they pressed the company about the shortfall, Sun Diego Solar insisted on a $5,000 charge to add the missing panels even though the sizing error came from the installation. The crew was friendly and the work finished in a somewhat timely way, but the persistent utility charges and the sight of unused rack space on the roof upset them every time they look at it. The detail that stays with GGG: an "upgrade" that left empty roof real estate and a $5,000 repair bill to fix the installer's mistake.

2. Jamie S.
Yelp | Feb 11, 2022 |

Jamie S. reached out to Sun Diego Solar & Construction for work on a residential solar system and discovered the owner, Rick, was also a licensed electrician — a detail that changed the whole project. They started with solar work and appreciated clear communication and straightforward pricing, then asked Rick to handle the electrical for a pool and hot tub after receiving wildly different quotes from other contractors. Rick and his crew completed the pool and hot tub wiring, and later returned to install an outdoor Tesla charger that now brings the car up to speed quickly. Because Jamie had to leave the house and garage open while crews worked, trust mattered; they felt completely comfortable with the team moving in and out of the home, and even the dogs warmed to the crew. Other tradespeople on the job noticed and complimented the neat, professional workmanship. The memorable takeaway: having an owner-operated company that combines solar expertise with licensed electrical work cut through confusing bids and built enough trust that Jamie will call Rick first whenever a job fits his skill set.

3. Fred Galloway
Google | May 11, 2022 |

Fred realized he needed a new roof and decided it was the perfect moment to add solar, so he collected five quotes and learned more about the process with each one. He chose Rick from Sun Diego Solar because Rick laid out options clearly and proposed a system and price that made sense. He appreciated that Rick didn’t just sell panels — Rick connected him with an excellent roofer and coordinated the work, so the roof replacement and solar install proceeded quickly and efficiently. The crew finished promptly, the equipment matched expectations, and after four SDG&E bills the system’s performance confirmed its efficiency. What stuck with him most was having a single knowledgeable point of contact who handled both the solar plan and the roofing recommendation, which smoothed the whole project.

What You Can Expect

01

1. Jeff R.
Yelp | Feb 6, 2019 |

Jeff R. chose Sun Diego Solar for a residential rooftop system and discovered their clearest advantage upfront: a noticeably lower price thanks to low overhead. He found the company handled the paperwork end-to-end—pulling permits for him—while walking him through options for panels, battery storage, and monitoring without any high-pressure salesmanship. The whole process moved quickly: from the first conversation to a finished install in just a few weeks. The installation has been sitting on his primary residence since April 2015 and has run without issues, which he points to as proof that a cheaper bid didn’t mean lower quality. He still gets teased by a friend for hunting bargains, but the trouble-free, long-running system is the detail that matters to him.

2. Charles B.
Yelp | Jul 12, 2017 |

In June 2016 Charles B. had Cheatham Solar install a 4.5KWh system on his roof. He worked through multiple quote options with the installer to match his energy needs and budget, and ended up paying less than the big corporate solar companies while getting more total power, quality branded panels and inverters, and micro-inverters instead of a single central inverter. The array performed to specification and produced the expected energy output. When he opened his first SDGE annual bill a year later, he discovered he owed only $44 — an amount he attributes to unavoidable NetMetering 2.0 charges from the utility. Because he uses A/C occasionally, he recommends sizing a system 5–10% larger than your baseline so you won’t cringe at summer bills and can accommodate likely increases in usage.

3. Joseph H.
Yelp | Aug 30, 2022 |

Joseph had Rick and his crew install a residential solar system and add eight panels a few months ago. He ended up pleased with the system’s performance and appreciated how quickly and smoothly the team worked, noting their clear customer focus. Trusting their work enough to return, he plans to contact them again when he’s ready to add storage batteries — a practical sign that the job met his expectations.

Paul Adams got clear answers to his questions up front, and the installation proceeded smoothly with no surprises. The crew worked efficiently on the roof, and his wife noticed how well they coordinated their tasks — the teamwork left the strongest impression and gave the job a professional, orderly feel.

3. Miles Pivonka

Miles Pivonka hired Rick and his team for a solar installation and discovered their speed was the standout. The crew worked quickly and efficiently, stayed professional throughout the job, and offered competitive pricing. He recommends them to anyone considering solar, and what stuck with him was the combination of a fast, no-fuss install and fair cost.

Yelp | Jan 30, 2019 |

Shannon H. chose Sun Diego Solar to outfit her home with panels about a year ago. She has enjoyed near‑zero electricity bills since and the relief of not having to worry about what next month’s charge will be. The crew installed only American‑made components, which boosted her confidence in the system’s reliability. Her takeaway after a year: consistently minimal bills and hardware she trusts.
