This review is based solely on the installation appointment and the team. The inspection hasn’t happened yet, so I cannot rate the installation or effectiveness of the equipment yet. Altsys Solar was selected by Sungevity to install our solar system. Once we received the approvals from our HOA, it was very easy to schedule an appointment to install on a day that met our needs. I thought it was interesting to have a company 3 hours away(on a good day) do the installation, but that was Sungevity’s thing, not ours. Altsys Solar brought a crew of 4 and upon arriving, they introduced themselves to us, asked basic pre-install questions, informed me of their activities, and went on their merry way. Oh, and they showed up early at 7am to survey the site from the outside, and didn’t connect with us until 10 minutes before our scheduled appointment at 8am. This was great because they came prepared. They got straight to work. Occasionally I would go outside and watch. We chatted and if I had any questions, they didn’t hesitate to answer and educate me. Everyone on the crew was professional. They spent most of the day working on the mounting system and wrapped up the last 2 hours actually putting on the panels and testing the system. When they finished(right on time based on their initial estimate), the crew walked me through their work and showed me how to use the system. It still needs to be inspected and approved to be connected to the grid, but that isn’t Altsys Solar’s responsibility. They were very respectful and clean — they didn’t leave any garbage or mess behind, and put everything back that they had to move to do the install. Thank you guys!
