当前的太阳能客户要么注册 Net Energy Metering（NEM），要么注册 Solar Billing Plan（SBP），具体取决于您何时获得运营许可（PTO）。
如果您申请接入符合条件的可再生能源自发电系统，例如太阳能或风能， 2023 年 4 月 15 日或之后，你是一个 Solar Billing Plan （也称为 Net Billing Tariff 或 NEM 3.0）客户。
如果您安装了符合条件的可再生能源自发电系统，例如太阳能或风能， 2023年4月15日之前，你是一个 Net Energy Metering 顾客。
现有 NEM 1.0 和 NEM 2.0 客户将继续使用 NEM 直至其遗产期限结束，即自其系统接入电网之日起20年，之后将过渡到SBP。如果现有的NEM客户将其发电系统容量增加超过10%或1千瓦，或者选择切换到SBP，也将过渡到SBP。
SBP was established by the California Public Utilities Commission in December 2022 as the replacement to NEM. It went into effect in April 2023 as a new approach for compensating renewable energy generation and is intended to promote grid reliability and incentivize solar with battery storage.

Adding battery storage can help maximize the benefits of your existing solar system.
Batteries can store the excess energy that your solar panels produce for the times when you need it most — like times of high demand, when electricity is more expensive, or even during power outages.
Community Power’s Solar Battery Savings Program can help single-family homeowners in our service territory add battery storage to their existing solar systems. Learn more on our Solar Battery Savings page.
If you’d like your battery to help offset the amount of energy that you are pulling from the local energy grid, it is best for your battery to be sized appropriately to the excess solar you are producing — if your battery is too large, your solar system won’t produce enough energy to charge the battery requiring you to charge it with energy from the grid.
However, if your primary reason for adding a battery is resiliency, then you may prefer to charge your battery from the grid during off-peak hours. Talk with your contractor to determine the best system size for you.
