Choosing the Best Solar Battery for Your Nigerian Home

The battery is the heart of your solar system. It determines how long your power lasts when the sun goes down. Here is what you need to know to choose the right battery. ## Battery Types Compared ### Lithium-Ion (LiFePO4) - Lifespan: 10-15 years - Depth of discharge: up to 90% - Efficiency: 95%+ - Cost: Higher upfront, best long-term value ### Tubular Gel - Lifespan: 4-6 years - Depth of discharge: 50% - Efficiency: 80% - Cost: Moderate ### Deep-Cycle AGM - Lifespan: 3-5 years - Depth of discharge: 50% - Efficiency: 85% - Cost: Lowest upfront ## Our Recommendation For most Nigerian homes, we recommend lithium-ion batteries despite the higher upfront cost. They last 2-3x longer than lead-acid alternatives and allow much deeper discharge, meaning you get more usable energy per unit of capacity. ## Sizing Your Battery Bank A properly sized battery bank should provide 1-3 days of autonomy. Our consultants calculate this based on your nightly energy consumption and local weather patterns.
