加州SOMAH计划让保障房租户共享屋顶太阳能：2025年参与租户户均月省电费58美元 约占月账单75%
加州公用事业委员会（CPUC）的「多户保障房太阳能」（SOMAH）计划为符合条件的多户保障房提供太阳能系统财政激励，让租户无需自行安装光伏，即可从所住楼宇的太阳能发电中获得电费抵免。该委员会10月26日介绍，据2026年5月发布的 SOMAH 评估报告，2025年参与租户平均每月省下58美元，约相当于其平均月电费的75%。
在参与物业，太阳能发电同时供应租户与走廊、洗衣房、社区空间等公共区域；借助「虚拟净电量计量」，一处系统的发电收益可在多个电表账户之间分配，抵免直接体现在租户的电费账单上。租户无需负责系统的运营与维护，租金也不得因安装 SOMAH 资助的太阳能系统而上调。对物业业主，SOMAH 激励最高可抵偿整套系统的材料与安装成本；2025年业主平均每月省下1,977美元，约占公共区域平均月电费的68%。
SOMAH 源于州议会 AB 693 法案，加州公用事业委员会于2017年完成计划设计，2019年开始受理申请，目标是在2032年12月31日前建成至少300兆瓦太阳能装机。截至2026年年中，已完工与在途项目合计约139兆瓦，其中约58兆瓦已投入运行。该计划还为符合条件的参与者提供就业培训，评估调查显示85%的参训者进入了太阳能行业；参与租户同时会自动加入「节能援助计划」。
加州公用事业委员会 SOMAH 首席分析师 Thovie Michaud-Gonzales 表示，该计划旨在让参与物业的租户从所在建筑的太阳能发电中直接获得账单减免，在降低电费的同时支持加州的气候目标。

California's SOMAH Program Brings Solar Savings to Affordable Housing Tenants: Average of $58 a Month in 2025
The California Public Utilities Commission's (CPUC) Solar on Multifamily Affordable Housing (SOMAH) program provides financial incentives for solar energy systems at qualifying multifamily affordable housing properties, allowing tenants to receive credits on their electricity bills without installing panels themselves. According to the May 2026 SOMAH Evaluation Report, cited by the CPUC on October 26, tenants saved an average of $58 per month in 2025, about 75 percent of their average monthly electricity bill.
At participating properties, solar generation serves both tenants and common areas such as hallways, laundry rooms, and community spaces. Through virtual net energy metering, the benefits of one system can be shared among multiple electricity accounts, with credits appearing directly on tenants' bills. Tenants are not responsible for operating or maintaining the system, and rent cannot be raised because of a SOMAH-funded installation. For property owners, SOMAH incentives can offset up to the whole cost of an eligible system; in 2025, owners saved an average of $1,977 per month, about 68 percent of the average common-area bill.
SOMAH grew out of Assembly Bill 693. The CPUC established the program design in 2017, applications opened in 2019, and the program is working toward at least 300 megawatts of installed capacity by December 31, 2032. As of mid-2026, completed and pipeline projects totaled about 139 megawatts, with roughly 58 megawatts already operating. The program also offers job training, and 85 percent of participating trainees surveyed said they obtained a job in the solar industry; participating tenants are also automatically enrolled in the Energy Savings Assistance Program.
"SOMAH is designed to enable tenants of participating properties to receive bill relief from solar generation where they live," said Thovie Michaud-Gonzales, the CPUC's SOMAH lead analyst, adding that the program makes bills more affordable while contributing to the state's climate goals.
