RES off-grid solar PV system installation, Donald Mott

Off-Grid System

“RES did the original install of my off-grid photovoltaic system 12 years ago and the 3 upgrades made to the system since. The last upgrade was just last week. I fully understand the complexities of my solar system and have the utmost respect for Roland and his team. They stay current on new technology and know what works best here. If you are on the Big Island, and you want a system that works correctly, call Roland and listen to what he says. RES does quality work and they stand behind it.”
