Solar Batteries: Types and Functions, and How to Store Them

Solar batteries are an essential part of solar power systems and work well with solar panels Newcastle. They store solar energy collected by solar panels during the daytime to be used at night or during a power outage. Solar batteries come in all shapes and sizes, and there are several factors to consider when choosing the right one for your needs. In this article, you will read about the different types and functions of solar batteries and how to store them properly. You will also look at how solar batteries work with solar panels to create a complete solar power system.

How solar batteries work

Solar panels are the most critical component of a solar power system. They collect solar energy and convert it into electricity that appliances in your home or business can use. Solar batteries store solar energy to be used at night or during a power outage, which means they’re essential if you want to use solar power around the clock. It’s worth noting, however, that solar batteries have a limited amount of storage capacity, meaning they will eventually run out if there isn’t enough sunlight available to recharge them regularly (this is known as “solar battery degradation”). This is why many people choose not to install solar batteries at all – instead of relying solely on grid-connected systems for backup purposes only when there’s no sun available for hours/days.

Types of solar batteries

There are various types of solar batteries on the market.

  1. The most common solar battery type is the lead-acid battery, which is usually less expensive than other solar storms and has a shorter lifespan.
  2. Lithium-ion solar batteries are becoming increasingly popular due to their high storage capacity and long lifespan – some models can last up to 20 years. However, they’re also more expensive than lead-acid solar batteries.
  3. Other types of solar batteries include nickel-cadmium (NiCd), nickel-metal-hydride (NiMH) and lithium-ion polymer (LiPo).

Charging and discharging a solar battery

The process of charging and discharging solar batteries is similar to solar panels. The solar panel system has solar cells which absorb energy from the sun and convert it into electricity. In contrast, the solar battery converts solar energy into a chemical form to be stored more efficiently.

A solar battery stores excess solar power generated by your home’s PV array when you’re not using it, then dispenses it back onto the grid at peak demand times, when wholesale electric rates are high. Or maybe during periods of bad weather when your panels aren’t producing enough power to meet all of your needs. Solar and storage systems allow homeowners who want to go off-grid with their homes but don’t necessarily have access to wind turbines or hydroelectric dams nearby to have power 24/7.

How to store solar batteries

Solar batteries need to be stored in a cool, dry place where there’s no risk of them being exposed to direct sunlight or excessive heat.

Pros and cons of using a solar battery with a solar panel system

  • They provide homeowners with peace of mind by allowing them to have power 24/7, whether the sun is shining or not.


  • Solar batteries have a higher price tag than other storage options like propane tanks or even diesel generators.
  • Solar batteries also require regular maintenance to keep them performing at their best.
  • If you’re thinking about adding a solar battery system to your home, be sure to factor in both the cost and the time commitment required for upkeep.
