    Do not hire this company. We have sent all documentation requested for solar service activation at Fox Point Farms and have neve heard back from them again. Followed up after two months but the thread with their activation team/representative produced no response, even after multiple attempts to follow up. Decided to call them and, to my surprise, nothing has been done to date. I got contacted by a subcontractor to schedule a photo session of the panel in a month from now. A photo session for the very same pictures I sent upon their request and they confirmed adequate receipt months ago. I und

    Do not use Complete Solar. They have the worse customer service and they can't coordinate schedules with customer, utility company, city inspector or their workers. They have been fined by utility company twice and because they don't pay the fines or the fee that is required by the utility company, we can't move forward. We have had solar panels on our roof for over a year, but still need electrical panel upgrades for two properties. No one ever returns our calls or emails. Also, don't trust My Smart House. They sold us the solar and then contracted Complete Solar to do the work. My Smart Hous

    DO NOT USE THIS COMPANY. I wish I would’ve took The time to review this company before I hired them, because the two star rating definitely speaks for itself, I’m truly surprised it’s not lower. Between the poor installation, the damage to my home and the general willingness to help it has been an absolute disaster and nightmare for me. I had more people scheduled to come fix things and no-show on me that I cared to count. I’ve spoke to several people claiming to be either managers or escalation department, whatever their title were and nothing has been fixed. Even after leaving a bad review w

    Update at the bottom!!! Original review: As for me everything was amazing up untill i was told by the installer that i was missing a sub back up panel to function properly. Since then i feel i have an incomplete solar system. I spoke to mirian who confirmed i am indeed missing the sub back up panel and promised to send someone out my way but now she completely avoids my messages and emails. I try to maintain good hopes with this company because everything was good and worked well so far. I hope someone will reach out and fix this problem. I will leave another review with an update to let you a

    This place has delayed my solar for a long time, but they are lucky their technicians are kind. Travis helped me out with our solar and was very kind and patient with me.

    UPDATE 2: This city showed up and signed off on August 1st, as promised. Everything is great now! I think if the company set a better expectation initially, that I would not be up and running until the city signed off and it could be a few months, then the first review I left would not have been necessary. Once I was able to get a hold of someone, communication was great...I had cell numbers for 2 employees (Carlos & Stacy) and always got a response. The installers were always great. Thank you, Complete Solar! UPDATE: Thank you for your response. The City is supposed to be here on August 1. I'

Topics Google derives from the review text, with how often each appears. A frequent topic is not a good one: “price” turns up in praise and in complaints alike.

What the company says about itself

Taken from its own website. We have not checked any of it, and a sentence on a website is not evidence.

    Its website also mentions warranty, free estimate and established, but not in a sentence we can quote cleanly.

    Elsewhere

    Who Google shows alongside them

    Google’s own “people also viewed” set, in Google’s order. It is Google’s comparison, not ours.

    The ones without a link have no page here, either because Google does not categorise them as solar businesses or because we could not match the name to a listing with confidence.

    Ordered by how much we can tell you about each, which is not an order of quality. We do not know which of these is better and would not say if we did.

    What we don't know

    • The date above is the newest review we hold, which is not necessarily the newest that exists — we hold a large share of Google's reviews, not all of them.
    • We do not verify licences, insurance or bonding. Nothing here has been checked against a state licensing board.
    • We cannot tell you what an installation costs, and we hold nothing about the equipment they fit.
