Los Altos Hills - 3.2 KW Grid-tied battery backup System
1 Outback PS2 inverter, 18 Sharp 208 modules
When I bid this job with several of the larger companies in the area, I learned that grid-tied solar will not deliver house power when the grid goes down. No larger company would attempt to go outside their "standard grid-tied install." Mark Thompson, owner, designer, licensed electrician and primary installer was willing to work closely with me to create a custom design and then complete the installation. He worked diligently to ensure I could get solar panels which were in short supply, dealt with a complicated roof install, and did an excellent job of the electrical wiring. System works as designed, roof doesn't leak, and the pricing was in line with the other two bids for the basic work. I added extra features which ended up costing more, but pricing was fair. Mark is flexible, diligent and a pleasure to work with. Watch out for his puns! Only complaint is that it took months to get started, many jobs ahead of me!
Description of Work: Ra Tech designed and installed a 3.2 kilowatt grid-tied renewable energy solar array with battery and generator back up. The system consists of roof mounted solar panels, an Outback grid-tied inverter, solar charging controllers and a large battery bank. In addition to the solar system, additional re-wiring was necessary to move most of the house loads to the battery back-up and an additional panel was added for the generator transfer.

Palo Alto - 3.0 Battery Backup Grid-tied System
1 Outback inverter, 22 Sharp 167 modules
The contractor, Ra Tech Solar, proprietor Mark Thompson, dealt with unanticipated problems, including that the warehouse sent defective parts. Mark fixed the problems at his own expense. He also did add-on work (installed a generator and changed wiring) at very reasonable, I thought extremely low add-on cost. I am extremely pleased with the job Mark Thompson and RaTech Solar did. You may call me at 650-856-2850. I am CEO of a nonprofit that works on other forms of renewable energy so I am aware of the benefits and issues.
