One of the monitoring features was never installed completely so it didn’t work, the breakers pop every time it rains, and had to have a roof leak fixed from broken tiles. And slow response to any issues. I've been trying to get them to resolve an issue for 2 months now and they won't even return my calls or send a technician. If you want a company that leaves you hanging with poor installation & nonexistent after-sales service, these are your guys! Not recommended.

I had a terrible experience with Nexus. Their sales tactics were incredibly aggressive. They swooped in after I received a quote from another company, immediately trying to undermine them with scare tactics about inferior equipment and unreliable warranties. It felt like they were more interested in poaching a deal than providing genuine service. The sales representative pressured me relentlessly, claiming that the deal was only available that day and that I would miss out on significant savings if I didn't sign immediately. When I asked for more time to consider, they bombarded me with alarmi

Nexus Solar cheated me on the contract. They offered quotation in writing, but had higher price on the contract which they never provide a copy of signed contract back to me. The contract I signed online had same info as they quoted, but when the service turn on, the payment is much higher. With the 32 panels installed, my payment to the solar contract is at $421 / month they billed, but got bill from SCE is $329.84 / July, $413.52 / Aug, $276.38 / Sept, $375.39 / Oct. I have been emailing and calling Nexus Energy and SCE, but got no response from none of them. Sharing this bad experience with

I am a very dissatisfied customer. Have been waiting over a month to get Nexxus to fix my system that has been offline for that long. This is the third time over the past 3-4 months that my system has been dropping offline. I also noticed my electricity cost goes up during the time the system is offline. Given my utility bill when the system is online, I now know they under-sized my system which ultimately hurts me. Buyers beware. Not so legit and I wish I could pull this off my house. Update: After posting, the company reached out, sent a technician and replaced faulty equipment. Now my syste

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.
