Our system was installed in December of 2020. So, this review has some value in reviewing the…read moremulti-year relationship between the supplier (XERO) and the consumer (me). It is not straightforward to review solar companies because, well, these are big $ projects and I don't get solar installed every month or every year. So, this review does not compare Xero to other solar companies. I would be writing a fairytale if I were to review them, say, against Tesla. Having that cleared up, let me start the review. First come the sales people. Did they take the time to understand what my wife and I were really wanting our solar system to do for us? Did they propose a system that would meet our needs? George B. was 'our' sales person. He is still with Xero 6 years later, albeit in a larger role. This is a very positive sign. Before you sign with a solar company, ask about turnover and who your contact will be as the project progresses. Xero gave us 'one stop shopping' and that has real value. George fielded all our questions, informed us of status and kept us informed about anything that impacted our project (everything from municipal permits, Southern Edison approvals, project progress, to Solar rebates. Xero continues to be stable. We had one 'sales' meeting where George worked with us to configure a system and set up a timescale and pricing. One funny thing did happen that I should tell you about. George assumed we were looking for a minimum cost system that would lower our electric bill. We had to explain that what we wanted was a system that would give the maximum backup power (battery plus solar) in case the grid went down. That type of system would then also have the property of giving us there lowest SCE bill. Our final system was: 40 panels, 4 Tesla Powerwalls, and all the support infrastructure needed. The price was in line with expectations, so we signed up. The project moved quickly. XERO produced the plans that would be submitted to SCE and the City for permitting. They also created all the paperwork that was needed to take advantage of the government rebates. We were having our roof redone at the same time as we were replacing a much older solar system with the Xero system. George coordinated Xero's work to put hardware in place to hold the panels so the roofers could seal the hardware against leaks. The installation of the solar system went quickly and according to the original schedule. We were up and running 'on schedule'. We have had a few problems since the 2020 installation. One of the LG panels died. Xero replaced the panel, but we also learned that LG is getting out of the solar panel business. If other panels die Xero said they would 'take care of it'. I trust them. Then, one of the Tesla Powerwalls kept tripping the first breaker between it and the rest of the system. That turned out to be due to the screw that fixes a (large) wire to a breaker loosening. Xero repaired that immediately. Probably the most concerning failure we had was that the main breaker, the Backfeed Breaker, that connects the solar/Battery Backup system to the grid, melted and disconnected us from the grid. We were running on battery and solar only for a few days. The good news is that the system as implemented can deliver enough power to run our home and charge our car from the sun alone. One of the very senior Xero folks saw the 'call for service ticket' and rushed right over on a Sunday afternoon. Then one of their very senior engineers came out and diagnosed and repaired the damaged system. This failure was also caused by a screw that fixes a wire to the breaker loosening. The installation crew used calibrated torque wrenches to torque every screw to its specifications. So, faulty installation was not to be blamed. Heating/cooling can cause this type of failure as the wire and screw are subject to expansion and contraction. Overall, Xero is great company. They are stable, have excellent leadership, proudly stand behind their brand, they don't leave you 'hanging', they are easy to deal with, they've been in business for quite a long time, they have a stable workforce. I recommend them highly. "But", you say "aren't you concerned about the failures? Especially the 'loose set screw' issue." Short answer: NO. These failures are bound to happen in electrical equipment that carries large currents (have a chat with one of the AIs about this). There are many issues that can cause such failures: heating/cooling caused by large currents that are not steady; for example switching Powerwalls from charging to discharging. Both loose connections were in high current areas where current direction changed frequently. The solution to these problems is 'maintenance'. Xero now offers annual maintenance contracts which will prevent the type of failure we have seen. That is the theory. We shall see how this works out in practice over time.

I am so impressed with this company that I had to write a review of my experience. I had my Tesla…read morepowerwall installed about a year ago, but a few months back my energy bill from SCE began to skyrocket. I contacted SCE, but after wasting a lot of time with them, they said there was "nothing they could do." After this frustrating experience I contacted Xero Solar because I didn't know what else to do. I first spoke to Rhetta, who was extremely efficient and helpful. She bent over backwards to stay in touch with me and followed through to make sure my issues were addressed. Then, she got Tina (also) from Xero Solar, to contact SCE on my behalf. Much to my amazement, they were able to negotiate with SCE to refund me the overcharges that should never have been applied in the first place. Mind you, my Tesla power wall had been installed over a year ago, and I doubt any other solar installer would stand by its customer this way. Xero Solar came through for me when I needed it. I highly recommend them for any solar needs.

Alan and the team at Solar Wholesale Group have been fantastic…read more They installed the solar system on our home over 10 years ago, and during a recent 400-amp electrical panel upgrade, they really came through for us. They were always available to answer questions, troubleshoot issues, and coordinate with our electricians whenever something came up. Because they knew our system inside and out, they were able to jump in quickly and help keep the project on track. Having that history with our home made a huge difference, and their professionalism and responsiveness took a lot of stress out of what was otherwise a complicated project -- all without having to break the bank. They are extremely fair with their pricing. It's one thing to do a good installation, but it's another to still be supporting your customers more than a decade later. That kind of long-term service is hard to find these days, and I'm incredibly grateful for everything Alan and Solar Wholesale Group have done for us. Highly recommend.

Just another 5 star review adding on to the many that NexGen Construction has and deserves. But…read moresince my particular project was for batteries adding onto existing solar panels that they did not originally install, I figured I can give my perspective with the service they provided. Without making this review long and boring, let me just say Eric the owner, Rich the office manager and Zach the lead installer (and the rest of the crew) was great to work with from beginning to end. I was anticipating that there might be some issues adding batteries on to an existing system, with not only the installation itself, but with the approval process from Edison and the city. But Eric, Rich and Zach worked as a great coordinated team to get through any obstacles that came up. Anyone who's been through any type of home construction/remodel knows that nothing is perfect. But it's how the people you hired responds to those hiccups to make things perfect, is what counts the most. And I can honestly say NexGen exceeded expectations. In regards to value, Eric is upfront and says they are not the cheapest, but they are certainly not the most expensive either. So when it comes to my peace of mind, I'd gladly pay a little more. Go ahead and give them a call, I certainly will when I want to add even more batteries

Roof - replacement took only 3 days , including gutters/downspouts. Solar - would have taken less than a few days, hadn't there been an issue with our electrical line location from main to sub panel (one of those unexpected unknowns). Solar install guys were great in that they made sure I was aware what equipment/line was going where and how is was going to be connected - we made a few small changes here and there and I really like the outcome. Powerwall / Solar has been running flawlessly since the hook up ... only downside to this project is my fam is mad at me for constantly showing them how much Kwh's they are using (large spikes when using the power wall app) :) Long live the sun!
