How Long Will My Solar Battery Last Calculator
While both can describe capacity, they have differences. Ah and mAh indicate how long a battery can discharge at a specific current. For example, a 10Ah lithium iron phosphate
Solar battery capacity typically measures in kilowatt-hours (kWh). A kilowatt-hour represents the energy usage of one kilowatt over the duration of one hour. For example, a battery with a capacity of 10 kWh can power a device that uses 1 kW for 10 hours or a 2 kW device for 5 hours.
Depth of discharge (DoD) indicates how much of a battery's capacity is used over time. Maintaining a DoD of 50-80% is recommended to optimize battery lifespan and efficiency, ensuring reliable performance during power outages. How does temperature affect solar battery performance? Ambient temperature significantly impacts solar battery performance.
Factor in your desired battery backup duration. If you want to ensure power for 2 days, multiply your daily energy consumption by 2: This calculation gives you the required solar battery capacity needed to meet your power needs during outages or low solar conditions.
Sites like EnergySage or SolarCalculator offer user-friendly interfaces that help you navigate the calculations effortlessly. Apps and software also play a crucial role in calculating solar battery capacity. Programs like PVWatts and Homer Energy provide extensive tools to model your solar energy system.
