Various Solar Battery Types
Every type of high capacity battery used with solar panels have their pros and cons. The main goal with any solar battery storage solution is to utilize energy produced during peak power production times (bright sunny days) during low-production periods (like nighttime and stormy weather). Also, a solar battery bank will prevent loss of power from a grid power outage.
Solar batteries store solar power, help reduce energy costs, and are an important part of renewable energy systems. There are several different types of solar battery systems available, but the two most popular options are lead acid deep cycle solar batteries and lithium-ion solar batteries.
Lead Acid Batteries
Flooded lead acid batteries and sealed lead acid batteries are both familiar and proven technologies for storing and reliably releasing energy when it’s needed. They are the same technology used in car batteries. Flooded lead acid batteries are also known as wet-cell batteries and require routine maintenance to maintain appropriate water levels. Sealed lead acid batteries do not require as much maintenance.
These types of deep cycle batteries are a great, affordable way to harness excess energy your solar array produces. They recharge slowly, though, and are not recommended for an off-grid solar system, but are ideal for homeowners on grid-tied systems.
Lithium-Ion Solar Batteries
Lithium-ion batteries are a newer technology that has become very beneficial in many energy storage applications. They are commonly used in cell phones and laptop batteries and other specialized uses. Their claim to fame is their high energy density, quick recharge times, and their ability to release energy rapidly. Ounce for ounce, they store the largest amount of energy and are ideal for off-grid systems, but they do pose a risk of catching fire if improperly charged/discharged.
