The cost of solar batteries is influenced by several key factors. Here are the most significant ones:
- Battery Capacity: The total amount of energy a solar battery can store is the primary factor affecting its cost. Larger capacity batteries, such as those capable of storing 20 kWh or more, are more expensive upfront but can provide longer backup power during outages.
- Battery Type and Chemistry: Different battery chemistries (e.g., lithium-ion, lead-acid, nickel-cadmium) and brands have varying price points. Lithium-ion batteries are generally more expensive but offer better performance and longevity compared to lead-acid batteries.
- Installation Factors: Costs are also influenced by whether the battery is installed simultaneously with solar panels or as a retrofit, as this affects electrical work and labor costs. Additionally, the choice of installer can impact the total cost.
- Balance of System Equipment: Additional components like inverters, mounts, and switches contribute to the overall system cost. Inverters, in particular, can add significant expense if purchased separately.
- Incentives: Federal and state incentives, such as the 30% federal tax credit and programs like California’s SGIP, can reduce the effective cost of solar battery installations.
