Sometimes energy storage is co-located with, or placed next to, a solar energy system, and sometimes the storage system stands alone, but in either configuration, it can help more effectively integrate solar into the energy landscape. What Is Energy Storage?
The AES Lawai Solar Project in Kauai, Hawaii has a 100 megawatt-hour battery energy storage system paired with a solar photovoltaic system. Sometimes two is better than one. Coupling solar energy and storage technologies is one such case. The reason: Solar energy is not always produced at the time energy is needed most.
Although using energy storage is never 100% efficient—some energy is always lost in converting energy and retrieving it—storage allows the flexible use of energy at different times from when it was generated. So, storage can increase system efficiency and resilience, and it can improve power quality by matching supply and demand.
The most common type of energy storage in the power grid is pumped hydropower. But the storage technologies most frequently coupled with solar power plants are electrochemical storage (batteries) with PV plants and thermal storage (fluids) with CSP plants.
PV system costs increased in Q2 2025 following the Trump administration’s implementation of 10% baseline tariffs in April 2025. While a 90-day pause on reciprocal tariffs was announced, the baseline tariffs remained in effect and contributed to price increases across solar market segments.
The AD/CVD case on solar cells and modules from Cambodia, Malaysia, Thailand and Vietnam, which began in April 2024 and was finalized on May 20th, 2025, increased module costs by 13% year-over-year across the distributed generation segments.
