1. Battery Storage
- Lead-Acid Batteries: These are more affordable but have a shorter lifespan compared to other options.
- Lithium-Ion Batteries: Widely used for both residential and commercial applications, they offer a longer lifespan and better performance. Common lithium-ion types include Lithium Iron Phosphate (LFP) and Nickel Manganese Cobalt (NMC).
- Flow Batteries: Suitable for longer duration storage, they store energy in liquid electrolytes.
2. Thermal Energy Storage
- Molten Salt Systems: Used primarily with Concentrated Solar Power (CSP) systems to store heat, which can later generate electricity.
- Solar Thermal Systems: Store heat for domestic hot water or space heating.
3. Mechanical Storage
- Flywheel Energy Storage: Uses spinning rotors to store energy kinetically, releasing it rapidly when needed.
- Compressed Air Energy Storage (CAES): Stores energy by compressing air in underground caverns.
- Pumped Hydro Storage: Although not exclusively for solar, it’s the most common form of large-scale energy storage, using excess energy to pump water into elevated reservoirs.
Each type of storage serves different needs based on scale, duration of storage, and integration with solar systems.
