When Gridley-area homeowner Vicke Robinson wanted to save money on her utility costs, a California environmental nonprofit company was happy to help. GRID Alternatives, an Oakland-based company, made Robinson the first Gridley-area homeowner to benefit from new rules for a state program geared to provide solar power to low-income homeowners. Earlier this spring, GRID Alternatives installed a 4-kilowatt solar power system at Robinson’s home. A total of 15 solar panels went up on the roof, installed by volunteers and trainees entering the growing solar field.
