Estimate how long it takes your solar panel to charge a battery based on panel wattage, battery capacity, voltage, and charge efficiency. Formula: Charging Time (h) ≈ (Battery Ah × V × (Target SOC / 100)) ÷ (Panel W × (Eff% / 100)). Adjust for sunlight hours to find daily charging duration. LFP batteries can safely use 80-90% DoD, while lead-acid should stay at 50%. Size your battery for 1-3 days of autonomy for grid-tied systems, 3-5 days for off-grid applications. If the panel's wattage is high, it can send energy to the battery more quickly, and. .
