There are several rebate and incentive programs available to residential homeowners and commercial building owners who install solar and energy storage systems that are powered by solar. Below are some of the most common current incentives available to customers installing a new solar system with Powerwall, or who may be adding a Powerwall system to a property that has an existing solar installation.
Powerwall qualifies for the Investment Tax Credit, or ITC, which is also commonly referred to as the Solar Federal Tax Credit when it’s installed with solar or retrofitted on a site with existing solar. Currently the ITC tax credit value is 26% of total system cost. It’s important to know that you should always ask your tax professional any questions you might have related to tax credit qualifications on your specific system.
The California Public Utilities Commission (CPUC) established the Self-Generation Incentive Program (SGIP) as a response to the 2000/2001 energy crisis and is one of the longest running distributed energy incentive programs in the US. In it’s current state, it is used to encourage energy storage installations throughout the state to reduce the overall strain ion the energy grid and the need to deploy expensive and environmentally hazardous fossil fuel power plants. The current program is aimed at residential customers to help reduce the cost of installing a clean energy system with energy storage.
The SGIP program is divided into different tiers or “Steps” that define a specific rebate amount. Powerwall installers are each allowed to apply for up to 20% of each step’s existing budget, which is why you may find some variance on whether or not a particular contractor can offer the SGIP rebate or not.
SGIP is aimed at smaller residential installs so certain restrictions apply on systems sized over 10kw. Southern California Edison, or SCE has a 150% rule stating the energy storage continuous output capability (5kw per powerwall) cannot exceed more than 150% of the solar generation AC output size. SGIP also stipulates a cycling requirement and requests system discharge data, so certain applications of your storage system, for instance, using it soely for backup power, may not be possible until the rebate stipulations are fulfilled.
It is ok to combine both the SGIP and ITC tax credit for your system if you qualify for both, so customers are encouraged to take advantage of both incentives on their systems.
Other state or utility-specific rebates my arise in addition to the SGIP incentives or ITC tax credit. It’s best to ask your account manager about any additional incentives or rebates that may be available, as these rebates have varying qualification stipulations and tend to expire relatively quickly based on limited funding.
