3/11/15 UPDATE
Okay so we're in a much better place as of today. It looks like all of the outstanding problems with the installation will be resolved by end-of-day, and as of this morning the system is fully operational (passed inspection, SDGE approval, etc.)
I do think that the root of nearly all of the issues we experienced was communication - internally within Stellar, and between Stellar and me as the customer. As recently as yesterday today there have been disconnects between what was happening on-the-ground for our solar project, and what staff at Stellar thought was happening (for example, I just received an email from Stellar staff asking me to pick an installation date for the PV monitoring system, which was actually installed yesterday...).
So again, for a "standard" installation that fits within Stellar Solar's routine provisioning and project planning approach, I think it likely we would not have encountered many, if any, of the problems that we did. As it was, we had a unique roof (concrete tiles over metal frame), wanted the SunPower 345 panels, a string inverter with emergency backup power, a custom system monitoring setup, etc. And each of these seemed to throw a wrench into the Stellar works.
But here's the bottom line: Stellar did fix all of the problems that arose when I asked them to. Sure, it would have been less stressful if the issues I touch upon below had not happened in the first place, but the fact that Stellar stepped up in a big way on their communication and attention to detail at the end of this project speaks well of their integrity, which is why I was happy to change the rating from 1 star to 3.
ORIGINAL REVIEW FROM 3/4/15
I don't usually post reviews that aren't related to food on Yelp, but working with Stellar Solar was enough of a disappointment that I wanted other solar shoppers to be forewarned...
Since the story is a long one, I'll just share a few important highlights:
1) Contract was signed October 16, 2014. Panels and inverter installation completed March 3, 2015, five months later, but with many problems (see below) along the way.
2) There have been consistent miscommunications and delays at every step of the project, with plentiful finger-pointing and excuses, but no one at Stellar willing to take full responsibility for the project.
3) Despite diligent communication on my part to help Stellar's team avoid damage to the roof, dozens of roof tiles are now broken. Initial attempts by Stellar's crew to "fix" the tiles involved caulking the broken pieces back onto the roof as a patchwork of cracks and unsafe roofing.
4) A lack of flexibility from everyone at Stellar Solar regarding a) negotiating the initial contract, b) effective communication procedures, c) scheduling on-site work, d) responding to considerations or requests that were unique to our property, e) responding to concerns about problems with the installation, etc.
5) Most disappointing of all, one promise after another was not kept. Over the entire process, I experienced that "Oh yes, I will definitely take care of that tomorrow" effectively meant "I won't be following through, and I won't be contacting you to let you know anything more about this either."
In response to all of these issues, when I raised them as patiently and calmly as I could with the project team, I always received the same formula from Stellar staff: Either they would insist "We will take care of this, we do this all the time, you don't have to worry," after which the install team would continue to make exactly the mistakes I was concerned about; or, anytime the situation seemed to be getting particularly dire, an offer of monetary compensation - to pay for electricity bills when the project installation kept getting pushed back, for example.
Unprofessional as all of this was, my patience has just about run out...so I decided to post this review. This may have been a 5-star company in years past, and perhaps with a simple, cookie-cutter installation Stellar may indeed do a decent job. But if you have a unique design, or if you want top-of-the-line SunPower panels as we did, or if you would prefer a string inverter instead of microinverters, or if you need to arrange special access times to your property, or if you expect your solar contractor to respond to your emails or phone calls...in our case Stellar Solar was simply unable to jump through any of these "customized" hoops without dropping the ball and causing us continuous grief.
Was their anything positive about this experience? Well yes, at the onset our salesperson, Mark, was actually a very nice guy. But so far that's really the only positive thing I can say about Stellar Solar. read more
