How long do solar batteries last?
When talking about solar panel installations, in most cases the assembly of solar batteries is usually avoided due to their price. However, thanks to grants that exist, it is now much cheaper to install a solar panel with a battery. And the truth is that the advantages that can be achieved by doing so are very great.
However, it should be noted that there are many types of solar batteries different. Something that is very relevant because their characteristics vary and the time in which they last working, as well as their autonomy, is different. So as we know that more and more people are interested in this type of storage for photovoltaic energy. Today we are going to delve into the solar panel with battery.
Solar batteries: what are they
To begin with, you must be clear that the battery is not a mandatory element in a solar energy installation. In fact, these facilities can function perfectly without them. However, in that case the energy that is produced and not consumed on the spot cannot be used later. Something that does happen with these storage systems.
Thus, a solar panel with a battery saves the electricity generated that is not being used throughout the day so that it can be consumed later. Thus, those who have batteries in their photovoltaic system can save energy to use it when their panels do not receive sun, such as at night, or when what their plates produce is not enough to cover energy demand.
How long do the batteries last?
Now that you know what a solar panel with a battery is, we are going to answer the key question of this post: how long do batteries last? First we are going to focus on its useful life, which varies depending on the type of battery in question. And right after we will talk about the autonomy that they can offer.
Lithium batteries:These batteries can be discharged up to 80% or 90% of their capacity and have a useful life of up to 15 years, so they are capable of withstanding up to 6,000 discharge cycles.
Stationary batteries:The useful life of these batteries, under the right conditions, is up to 15 years. Of course, the discharge cycles, up to 60% discharge, are reduced to 2,000.
gel batteries:These batteries allow a more intensive use and do not require maintenance. Its duration in cycles is about 1,200, while if we talk in years they can reach 15 depending on its use.
AGM batteries:They do not require maintenance and can offer a useful life of approximately 12 years.
What is the autonomy of the solar panel with battery?
Regarding the autonomy of the batteries, everything depends on the storage capacity they have. In this way, the amount of energy they can store can vary greatly from one to the other. As a general rule, batteries they can offer electricity for three or four days. However, the ideal is to correctly size the number of batteries needed so that their discharge level is optimal.
