Thoughtful proposals, no pressure. Several customers describe the proposal as detailed and straightforward, and say they did not feel pushed into add-ons or upsells. Representative review excerpt: "While not the least expensive option, we found the proposal to be thoughtful and thorough."

One price-sensitive comparison. A small number of reviewers mention that Altadena's quote was higher than another option they considered, so price fit can still matter in the sales stage.

One callback delay complaint. A single review reports difficulty getting a prompt callback and mentions the company saying it was short on technicians, so communication was not always seamless. Representative review excerpt: "Their first thing they say is that "

Reviewers often say the project moved smoothly through permitting, paperwork, and activation, and several describe the system coming online earlier than expected.

Permitting and paperwork handled well. Customers report that Altadena helped manage city permitting and related paperwork, which made the process feel easier.

One site-planning concern. A single reviewer says a request to adjust panel angle for appearance was postponed until after inspection, indicating a minor site-care or design follow-up concern. Representative review excerpt: "I asked them about dropping the angle of the panels, to make them not visible, and they said they would look into it after we passed inspection."

Reviewers generally report strong post-install performance, including good production, responsive support, and quick help when monitoring or follow-up questions came up.
