The best battery for a solar system depends on your energy needs, budget, and preferences. The most common options are:
- Lithium-Ion Batteries: These are highly efficient, lightweight, and durable, with a longer lifespan compared to other types. Popular options include Tesla Powerwall, LG Chem, and Huawei Luna.
- Lead-Acid Batteries: A more budget-friendly option, but they have a shorter lifespan and require maintenance.
- Flow Batteries: Ideal for large-scale systems, offering long life cycles and scalability, though they are more expensive.
For most homeowners, lithium-ion batteries are the preferred choice due to their efficiency and long-term cost savings.
The duration a 10kWh solar battery will last depends on your energy consumption:
If you use 1kW per hour, it will last approximately 10 hours. If your household consumes 5kW per hour, the battery will last about 2 hours.
For reference, an average home in Portugal consumes around 8–10kWh daily, meaning a 10kWh battery could potentially power your essential appliances overnight.
For off-grid solar systems, batteries must store enough energy to supply power when there’s no sunlight. The best options are:
- Lithium-Iron Phosphate (LiFePO4) Batteries: These are durable, efficient, and have a longer lifespan, making them the top choice for off-grid systems. Brands like BYD, Pylontech, and Freedom Won are popular.
- Deep-Cycle Lead-Acid Batteries: While cheaper upfront, they require regular maintenance and have a shorter lifespan.
- Flow Batteries: Great for large-scale off-grid systems due to their extensive charge-discharge cycles and scalability.
Lithium-ion batteries are often the best balance of performance, longevity, and cost.
The number of batteries depends on:
- Daily Energy Consumption: Calculate your average kWh usage per day.
- Battery Capacity: For example, if you use 20kWh daily and your battery stores 10kWh, you’ll need at least two batteries.
- Days of Autonomy: For 2–3 days without sunlight, you’ll need more storage.
For most off-grid homes, 2-4 high-capacity lithium-ion batteries are sufficient, though exact needs vary based on energy habits.
The size of the battery required depends on:
- Your Energy Consumption: A typical home might consume 8–15kWh per day.
- Desired Backup Duration: For one full day of backup, you’ll need a battery capacity of 10–15kWh.
- Usage Priority: If you aim to power only essentials (lights, refrigerator, and heating), a 5–10kWh battery may suffice.
For a fully off-grid system, a capacity of 15–30kWh is recommended to account for higher usage and autonomy during cloudy days.
