Serving a Constant Demand
Energy from Storage Immediately Available
Solar energy is inherently variable – not a natural fit for baseload needs.
Without energy storage, solar is limited to serving roughly 30% of a constant demand.
Bulk energy storage is needed to shift the majority of daytime energy for a 100% solar supply.
