Things to Consider When Choosing the Best Solar Battery for Home Use
Backup Storage vs. Bill Savings: Decide whether your main goal is to have backup power during outages or to save money on daily utility bills. Using a battery for frequent daily usage can reduce the amount available for emergency backup.
Cost: Prices for solar batteries vary widely and are often customized for specific installations. EnergySage noted that in late 2024, battery prices averaged $1,133 per kWh, excluding potential state or federal incentives.
Capacity and Power Output: Ensure that the total and usable capacities align with your energy consumption needs. Consider the depth of discharge (DoD) and output power, particularly for homes with multiple appliances.
Compatibility: Check that the battery integrates with your solar system. DC-coupled batteries are efficient for new systems, while AC-coupled batteries are better for existing setups.
Expandability: Choose a battery system that allows for stacking or connecting multiple units to accommodate future energy needs without requiring a complete overhaul.
Battery Composition and Guarantees: LFP batteries, such as those from BYD, offer cost-effectiveness and longevity, while NMC batteries, like Tesla’s, provide high performance at a higher cost. Ensure the warranty covers at least 10 years, with clear capacity retention terms to secure your investment.
