A review of LA Solar Group’s recently developed panel manufacturing division reveals info about cost, background, quality and more. The popular installer company only recently started manufacturing their own solar panels in order to become vertically integrated, offer more competitive pricing and a strong warranty, and shelter themselves from supply chain issues. LA Solar’s panels have competitive wattages and efficiencies plus discreet aesthetics. They also cost $2.35-$2.95/W, which comes to about $14,100-14,700 for a 6 kW system.
