Why We're Green

We are "Green" as each member of our staff arrives at work to install a solar system of offset the Global Climate Crisis one module at a time. Each member of our staff is contributes to the Green Team. We use as benign materials as possible and recycle cardboard, paper, steel, aluminum, copper, and plastics, and plastic bags. A solar installation pays for itself by offsetting the homeowners electric bills. "Old solar modules" are repurposed whenever possible. A1 Sun has driven electric since 2007. A Nissan Leaf is charged at our office for site visits. We work locally only traveling small distances. We purchase environmentally friendly office supplies and products whenever possible.
Maintaining Alameda County Green Certification validates our efforts on behalf of the Earth!


"If we weren't Green Certified, I'd question the certification process."
