Comprehensive Incentives for Businesses

Investment Tax Credit (ITC)

The Federal ITC allows for-profit businesses to deduct 30% of the total system cost for solar and energy storage systems (ESS) from their taxes.

The Federal ITC also allows non-profits to receive an actual tax rebate check of 30% of the total system cost for solar and energy storage systems (ESS).

Projects meeting specific requirements can qualify for additional “adders,” up to 10% each for:

  • Projects in Energy Communities

  • Low-Income Areas

  • Domestic Content compliance

The Inflation Reduction Act (IRA) last day of eligibility is December 31st, 2025.

Additional deadline requirements:

  1. Project commitment contract signed no later than December 31st, 2025 - No funds required at this time.

  2. Safe Harbor 5% Project Progress by July 4, 2026 (excluding permitting) - Funding per contract Schedule of Values (SOV)

  3. Project completion with active energy generation - December 31st, 2027

Federal MACRS Bonus Depreciation

Under the Modified Accelerated Cost Recovery System (MACRS), solar and ESS investments can be depreciated over five years.

In 2025, businesses can benefit from 60% bonus depreciation, allowing them to deduct a large portion of the system’s cost in the first year, with the rest depreciated normally.

State 10-Year Straight-Line Depreciation

Businesses can also utilize state depreciation benefits, which divide the equipment cost over its useful life for consistent annual tax deductions.

Self-Generation Incentive Program (SGIP)

California’s SGIP provides rebates for installing energy storage systems, enhancing energy resiliency while lowering costs.

Net Energy Metering (NEM)

NEM allows businesses to sell excess energy back to the grid, offsetting utility costs and providing ongoing savings.

Local and Utility-Specific Incentives

Many utilities in California offer rebates and programs tailored to solar and ESS installations. Contact us to identify programs specific to your location.
