Tomorrow, California’s state legislature will vote on lifting the current cap on the amount of energy in the state’s energy portfolio that can come from net-metered solar installations. Set at 2.5 percent, the net metering cap once seemed generous but now seems low–dangerously low, in fact, for the California solar industry. Successful solar incentives have encouraged nearly 460 MW of solar installations just within the service territories of the three investor-owned utilities (for more on the California Solar Initiative, start here).

Net metering is a huge piece of the incentive puzzle for solar homes and businesses and without it, solar growth will suffer a severe blow in the state that has so far blazed a trail for the rest of the country. Bill AB 510–last year’s doomed AB 560, reincarnated–would raise the cap to 5 percent, effectively ensuring long-term growth for California solar.
