The rapid growth in the energy storage market is similarly driving demand for project financing. The general principles of project finance that apply to the financing of solar and wind projects also apply to energy storage projects.
Since the majority of solar projects currently under construction include a storage system, lenders in the project finance markets are willing to finance the construction and cashflows of an energy storage project. However, there are certain additional considerations in structuring a project finance transaction for an energy storage project.
However, with the passage of the Inflation Reduction Act of 2022, tax credits are now available for standalone energy storage systems, and thus lenders may be willing to provide bridge capital that is underwritten based on the receipt of proceeds from an anticipated tax equity investment, similar to renewable energy projects.
An estimated 387 gigawatts (GW) (or 1,143 gigawatt hours (GWh)) of new energy storage capacity is expected to be added globally from 2022 to 2030, which would result in the size of global energy storage capacity increasing by 15 times compared to the end of 2021.
Read more about the different solar financing options available. In 2025, solar.com Energy Advisors typically recommend using a solar loan to finance a solar system — if the homeowner can efficiently monetize the 30% federal tax credit. If they can't, then a solar lease or PPA is the best option.

Homeowners installing solar panels and batteries in 2025 are smart to try to get ahead of tariffs, utility rate increases, and the risk of the solar 30% Federal Investment Tax Credit going away early. However, they're faced with interest rates that are significantly higher than they were just a short couple of years ago.
Offshore Wind: Battery energy storage systems (BESS) present unique financing challenges. For those interested in residential applications, energy storage systems offer compelling benefits for homeowners looking to maximize their solar investment: Emerging Solutions: Green Hydrogen:
Most groups involved with project development usually agree that energy storage projects are not necessarily different than a typical power industry project finance transaction, especially with regards to risk allocation.
Residential customers are typically driven by up front capital costs of the system. For this reason, OEMS have been driven to develop standardized systems easily incorporated into the surrounding PV system. The value of the energy storage system to residential customers is driven by both their physical and economic situation within the grid.
This is understandable as energy storage technologies possess a number of inter-related cost, performance, and operating characteristics that and impart feed-back to impacts to the other project aspects. However, this complexity is the heart of the value potential for energy storage systems.
Luke has been with 8minute Solar Energy for two years where he is the Senior Director for Storage and has three announced PPA's totaling 435 MW and nearly 2 GWh of energy in solar plus storage systems.
