The most commonly used energy storage technologies with solar systems include:
Batteries
- Lithium-ion Batteries: These are the most popular choice due to their high efficiency and long lifespan. They are widely used in residential and commercial solar applications, such as Tesla Powerwall and LG Chem RESU.
- Lead-acid Batteries: While less efficient and with a shorter lifespan than lithium-ion, they remain an option due to their lower cost.
- Flow Batteries: Suitable for longer duration storage, these are ideal for utility-scale applications.
Thermal Energy Storage
- Molten Salt Storage: Used primarily in Concentrated Solar Power (CSP) systems, where solar-generated heat is stored for electricity production during periods without sunlight.
- Ice Storage: Effective for reducing cooling demands by pre-cooling buildings, allowing for more efficient AC operation during peak hours.
Other Technologies
- Pumped Hydroelectric Storage: Though not typically co-located with solar, it is a prevalent form of energy storage globally, particularly at utility scale.
- Compressed Air and Flywheel Storage: Less common with solar but used in general energy storage applications for short-term power needs.
These technologies help mitigate the intermittency of solar energy, allowing for a more reliable supply of electricity when the sun is not shining.
