California Solar

California continues to be the leading solar market in the United States. A plethora of sunny days combined with supportive solar policies have created an ideal solar market. As older fossil-fired and nuclear generation plants (such as SONGS) come offline, statewide carbon reduction efforts escalate, and load growth increases (due, in part, to the anticipated increased deployment of electric vehicles), additional renewable energy procurement will be required within California. These factors, as well as changing consumer behaviors related to electricity production and delivery, offer substantial opportunities to continue to grow the solar energy market in California.

    2014 Legislative Update 

    Solar Property Tax Exclusion Extended

    In July, Governor Brown signed SB 871 which extends the existing solar property tax exclusion until January 1, 2025. The continuation of this policy will allow homeowners and businesses to install solar energy without a reassessment of their property taxes. In addition, extension of the exclusion will enable California utilities to achieve their renewable energy targets at a lower cost to ratepayers.

    SEIA California State Solar Policy Priorities

    • Encourage policies promoting robust penetration of customer-sited and wholesale distributed generation to help meet the Governor’s 12 GW goal.
    • Establish a favorable net energy metering successor tariff (NEM 2.0) that ensures robust market growth.
    • Protect and expand residential and commercial utility rate design which encourages deployment of customer-sited solar energy.
    • Enable access to solar energy to ratepayers who otherwise would not have had such access, such as apartment tenants and low-income customers. in the state with 6,454 kW of solar capacity at their location in Folsom.
