Factors to Consider When Choosing a Battery for Your Solar Energy System
The use of solar energy in homes is growing in popularity as more people discover the amazing benefits that this type of energy offers. Not only does it save homeowners from spending so much on energy bills every month, but it also helps to preserve the environment. If you are one of those people who are conscious about how their activities impact the environment, then solar energy is a great option for you as it will lower your home’s carbon footprint tremendously. For you to be able to reap maximum benefits from your solar energy system, you need to have a good battery to store the solar energy. There are numerous storage options available on the market, and you can easily get confused if you do not know what features the best house batteries should have. This article highlights some of the factors that you need to consider when choosing a battery for your solar energy system.
1. Depth of discharge
With most solar batteries, it is not advisable to use 100% of the charge stored before recharging. The battery must always have some charge in it. Otherwise, it will wear out very fast and you will need to replace it sooner. The depth of discharge is the amount of charge that has been used. Most batteries have a specified maximum depth of discharge, and you should never exceed this if you want your battery to serve you for a long time. It is therefore a good idea to choose a battery with a high depth of discharge.
2. Capacity and power
Capacity refers to the maximum amount of electricity a solar battery can store. It is measured in kilowatt-hours. It is a good idea to go for solar batteries that are stackable. This means that you can combine several batteries to store more electricity. Power, on the other hand, refers to the amount of electricity that can be provided by a battery at one time. It is therefore important to consider the power rating as well, as this determines how you can use the electricity. If you need a battery that can deliver a small amount of electricity, but for a long time, you should go for one with a low power rating and a high capacity. However, if you need a battery that can run your entire home, but for a short time, you should go for one with a high power rating and a low capacity.
3. Battery life and warranty
You want a battery that will serve you for a long time so that you do not have to keep replacing it. Note that as the battery gets older, it will start discharging faster than it did when it was new, and you will eventually need to replace it. Get a battery with a long battery life. It is also advisable to get a battery with a warranty so that you can get a free replacement in case it starts having performance issues before the warranty period expires. A warranty also gives you an assurance of quality.
