Without storage, excess solar energy is exported for pennies (net metering is fading in many regions). An EESS lets you and use it at night, boosting self-consumption from 30% to over 80%.
| Technology | Best for | Lifespan | Notes | |------------|----------|----------|-------| | Lithium-ion (LFP) | Home & commercial | 10–15 years | Safe, high cycle life, affordable | | Lead-acid | Low-budget, off-grid cabins | 3–5 years | Cheap upfront, but short-lived | | Flow batteries | Large commercial/industrial | 20+ years | Expensive but infinitely recyclable | | Sodium-ion | Future budget storage | 10+ years | No lithium/cobalt, still maturing | Without storage, excess solar energy is exported for
As the world shifts toward renewable energy, have become vital for maintaining power grid stability. high cycle life
