Solar Battery Options

For residential solar, lithium-ion is typically the best choice for efficiency, lifespan, and low maintenance. Lead-acid is budget-friendly but lower performance. Flow and solid-state are promising for large-scale/future use.

For Budget-Conscious Homeowners

• Lead-Acid: Low upfront cost; shorter lifespan, more maintenance, lower energy density.

For Performance & Longevity

• Lithium-Ion: High efficiency, long life, high energy density, low maintenance; higher cost.

For Large-Scale / Future-Focused

• Flow Batteries: Scalable; developing tech, not practical for homes yet.
• Solid-State: Potentially safer, higher density/longer life; emerging tech.
• Saltwater: Eco-friendly; lower energy density; niche/off-grid scenarios.
