Off-Grid Solar Systems
Battery Bank Options for Your Off Grid Solar Power System
Battery storage is one of the key elements of an off-grid solar system. After all, solar power can only be made when panels are receiving sufficient light from the sun. During foul weather or during the night, the battery bank will supply energy to your home until the solar panels can begin producing energy again. High capacity solar batteries provide electricity consistently.
Lead Acid Batteries
Lead acid batteries are an affordable battery backup option for off grid solar systems. Wet cell lead acid batteries require routine maintenance, while sealed lead acid batteries do not. Lead acid solar batteries are readily available and less expensive than other options. However, these batteries do not have the same depth of discharge capacity as lithium batteries, meaning that you’ll need more to store the same amount of energy.
Lithium batteries are a newer technology that is showing great promise for solar energy storage. They have a long life, require minimal maintenance, and ounce for ounce store the largest amount of energy of any battery option available. This efficient electricity storage is why they are a popular choice for homeowners designing off grid solar systems for their home. However, they can be prohibitively expensive.
