My Robco Solar system went live 5 days ago and appears to be running at projected production (I'll come back and update if it proves otherwise).
Very pleased with my decision to go with Robco, they weren't the cheapest but also weren't the most expensive. Personally I wouldn't make a purchase like this purely on price, a can of soup yes, this no. In the end I felt like I got a fair price.
Sales process was smooth, my sales representative Kyle was great, quite honestly he blew the other companies representatives out of the water when it came to knowledge and ability to answer difficult questions and go off "script." Provided very detailed information on products and production. Was also honest with me in an area of the purchase that not a single other sales representative mentioned to me.
In addition to the sales representative I went with Robco because they're also an electric company, solar isn't their only line of business. Also, their equipment/premium panels backed by another company where solar isn't their only line of business. Lastly the production guarantee. Others seemed to shy away from this, Robco included it as part of their presentation. Lastly they're a locally owned company.
From signing of contract to go live was about 8 weeks, and the majority of that was waiting on the city inspector and NV Energy. Install was smooth, courteous and clean workers.
Very pleased with Robco and can highly recommend.
