You will probably have heard about solar batteries if you consider switching to solar power. These devices store the energy generated by solar panels, allowing you to use it when the sun is not shining, such as on cloudy days and at night. In this comprehensive guide, we hope to answer all your questions about solar batteries and help you find the right solar battery system for your home.
How Solar Batteries Work
Solar batteries store the excess energy generated by solar panels during the day so that you can use that electricity when the sun is not shining. They are essentially large rechargeable batteries that can store electricity for later use. You will also need a solar battery system installed when solar panels are installed. Otherwise, you may not have electricity available at night or overcast days.
What To Look For When Choosing a Solar Battery?
As outlined below, it would be best to consider several factors when choosing solar batteries.
- Capacity: The capacity of a solar battery is measured in kilowatt-hours (kWh), and it determines how much energy the battery can store. The larger the power, the more fuel you can store and use later.
- Depth of Discharge (DoD): The DoD is the percentage of the battery’s capacity that can be used before recharging. A battery with a higher DoD can store more energy and provide more power during outages.
- Efficiency: The efficiency of a solar battery refers to how much energy is lost during charging and discharging. A more efficient battery will waste less energy and provide more usable electricity.
- Lifespan: The lifespan of a solar battery is determined by the number of charge cycles it can undergo before it needs to be replaced. A battery with a longer lifespan will naturally save you money in the long run.
- Cost: Finally, you will need to consider the price of the solar battery. Lithium-ion batteries are more expensive than lead-acid batteries, but they also last longer and require less maintenance, saving you long-term money.
