Effective on January 1 2015, California State Incentive (CSI) administration just modifies its handbook to allow GLE Solar products with 90 degree tilted installations into the California incentive program. This is good news for GLE Solar solar water heater products to open more opportunity in California state. See the handbook on our website:

GLE Solar patented products are designed for vertical installation, as free stand units, as a fence or units integrated into construction, delivering the best performance for domestic hot water supply, pool heat and commercial hot water supply systems.
