We received multiple estimates from several companies for a small solar PV system of approximately 3kW DC to go on our roof. Of the providers that we viewed as reputable, Stellar was initially in the middle of the pack for price, among comparable systems. The salesman/designer that we worked with was Zac, and he went through many options for us, including considering a new inverter (SMA 3000 TL-US) that was coming to market at about the time we'd be going forward with solar. This new inverter had a few new features (a power outlet that would work in case of grid failure, while sunny, and an option for an ethernet port instead of the much more expensive SMA webbox for monitoring), and Stellar was amenable to us dropping the webbox, going with the new inverter, and waiving the monitoring through Stellar (I monitor the system myself, very easily, that is what the ethernet part of the inverter allows). In my particular case, this worked and saved about $1000 (every situation is different, of course, but the fact that Zac was even open to this as a possibility was a big plus for me). This, and the fact that Stellar would do the main electrical panel upgrade for a completely reasonable price made Stellar an easy choice for us. Now on to the work. Everyone we've worked with at Stellar was very professional, helpful, etc, and the process went very smoothly, with the solar turned on and running slightly ahead of schedule. We went back and forth with Zac for a few days getting all the options settled on, and the initial design drawn up, and the contract signed, the first week of June (Zac was very helpful in this process, responding to my large number of questions, etc...). The process was supposed to finish by the end of September. After the contract was settled on, and the system was designed to our specifications, we were handed off to Joe Bowden, who kept us apprised of the process the whole way. After permits were drawn up in early July, they were issued on July 15 or so, and the system was up on the roof on July 17, well ahead of prediction. The crew that installed it did a great job, and all the electrical conduit runs are hidden under the panels and in the garage, for a very clean looking install. Next came the electrical work (electrical panel and grid-tying). This involves SDG&E, which causes some delay, but this was finished August 13. At this point, they found a short in the installed inverter, but swapped it out with the manufacturer quickly. Final inspection took place without a hitch on August 23 or so, and SDG&E gave the OK to turn it on on August 28. I think that the stucco repair for the electrical panel upgrade was probably subcontracted out, but this is the only part that I believe was subbed out (though I am not positive on that). There really wasn't anything I wasn't completely satisfied about the whole job. They were reputable (not at all sketchy), professional and responsive. They were flexible enough to let me choose a setup that saved us money (which means a quicker payoff time), their work was great quality, and their electrical work was reasonably priced. And when the one problem did come up (the inverter not working out of the box), they worked with the manufacturer to replace it in a matter of a few days. And, from contract signed to solar running (and with almost a month of data, it's producing as expected) was less than 3 months. I heartily recommend them.
