Solar Batteries 101: What You Should Know

Updated: Dec 2, 2022

A great advantage of solar batteries is their ability to store energy during the daytime, allowing homeowners with solar energy systems to tap into this power source at night without relying on the grid. Besides saving money on electricity costs, homeowners can also have the peace of mind that they will still have power for important appliances during a blackout. Anyone whose electricity has gone out during a winter storm – or really any other time - can appreciate how challenging it is to live without power even for a short while.

How do solar batteries work? In simple terms, excess energy produced by solar panels charge the battery, and this energy is released when needed. With a solar monitoring system installed as well, every detail of energy consumption and generation can be monitored and recorded.

Lithium-ion batteries are the most popular type of solar battery because they are compact, can store more energy than other types of batteries, and have a higher depth of discharge, or DoD. DoD refers to the degree to which a battery is emptied relative to its total capacity. So, if a battery has a DoD of 90 percent, it can use up to 90 percent of its capacity before it would need to be recharged. Solar batteries have a high cycle life, so they can be charged and discharge energy thousands of times without the need for replacement. Generally, you can expect a solar battery to last between 5 and 15 years.

Unlike generators, which are noisy and require regular maintenance, solar batteries are quiet and nearly maintenance-free. They don’t require gas or oil nor do they contribute to air pollution. Together with solar panels, solar batteries are an investment that pay off over time, saving homeowners on their electricity bills and providing a back-up during power outages.
