What to clarify before signing with Solar Optimum
Even with a strong record, these are worth confirming — the same questions apply to any installer.
- The deposit and refund terms in writing, including the cancellation window
- That the quoted price is the price on the signed contract, before any site survey
- Exact panel, inverter and battery models, and their warranties
- The project timeline and your point of contact through to PTO
In our full 433-review analysis of seven LA installers, Solar Optimum ranked third overall and had the lowest complaint rate of any company with a large review base (7%). Cali Energy had no one- or two-star reviews on a smaller sample; Solar Optimum's larger sample makes its record more statistically proven. Genuinely, the two are close. This dataset does not establish whether either company's model is “better.”
