If you are thinking of buying batteries for solar panels, but you do not know if it is really convenient for you to buy one or what is the capacity of a solar battery that best suits to your needs to determine which solar battery to choose, this post interests you! We tell you why it is convenient to use batteries for solar panels and what are the keys to knowing how to calculate the capacity of the solar battery you need.
If there is a device that should not be missing in your photovoltaic installation in addition to a solar panel, it is a solar battery with which to accumulate the energy it produces. But why is it important to calculate the capacity of your batteries for solar panels? Very simple!
Since the batteries for solar panels are one of the most expensive parts of the solar installation, it is essential to provide them with adequate care and maintenance to avoid their deterioration and to prolong their useful life. And it is that, if our photovoltaic installation is not installed correctly or an overload occurs, the useful life of the solar battery may gradually decrease over time.
However, this is something that we can avoid if we previously adequately calculate the capacity that we need for the solar battery that we are going to buy, and hence its importance!
Why should you use batteries for solar panels?
If you don't know whether or not to buy a solar battery for your photovoltaic solar system, you should know that, although they are not usually cheap, their advantages are more than enough reasons to decide to install batteries for solar panels, and the The main thing is the economic savings it allows.
You must not lose sight of the fact that batteries for solar panels offer you the possibility of storing all that solar energy generated by a solar panel, when you do not consume it, instead of sending it back to the network electrical. In other words, with a solar battery you will be able to make more efficient use of electricity, since all the energy it stores will always be available for your consumption when you need it most and you will not "lose" it.
Less pollution
With batteries for solar panels you can forget about using the conventional electrical network and therefore, you will contribute to reducing the carbon footprint while taking care of the environment.
Thanks to the fact that this type of energy depends fundamentally on the sun that falls on each solar panel, it does not entail using fossil fuels to produce electricity.
Self-sufficiency and energy independence
What happens if you need power during a cloudy day or at night? Batteries for solar panels will provide you with the electricity you require!
The excess electricity is stored for later use in the solar battery, so that during the night or on days when there is no sun shining on your solar panel, you can consume the accumulated energy (even , according to the solar battery, for a couple of consecutive days without sunlight) and you will not depend on the electrical network. You will be energetically independent and self-sufficient!
Power supply without cuts
One of the biggest advantages of having a solar battery, in addition to a solar panel, in your photovoltaic solar system is that you will be able to have solar energy throughout the day to power your electrical appliances and devices. Even in the event of a blackout!
All the electricity generated throughout the day by your solar panel that you have not consumed, you can use it with total normality and continuity in the event of any unforeseen energy event, or on those days when you require more energy and there is not enough sun . Thanks to the fact that the energy is stored in the solar battery, you will never be stranded without electricity, you will have a power supply without interruptions!
What exactly are batteries for solar panels?
Batteries for solar panels, such as the different types of BLUETTI portable power station, are the element of the photovoltaic installation that is responsible for storing all the energy produced by each solar panel. With what thanks to them, we can use the solar energy obtained at any time (as we have said before, even when it is night or the day is cloudy).
In this way, if you install batteries for solar panels in your photovoltaic installation, you can disconnect from the electricity grid and consume free and renewable energy. Of course, you must bear in mind that a solar battery is not eternal, so after a few years (each battery has a certain useful life), you will have to replace it. Until then, enjoy solar energy!
Types of batteries for solar panels
There are several types of batteries for solar panels: Monoblock batteries, Deep Cycle batteries, AGM batteries, stationary batteries and lithium batteries. But if you are wondering what are the best batteries for solar panels? The best solution is a BLUETTI battery or portable power station , a type of rechargeable lithium battery with which you can have unlimited power without interruptions at any time.
A BLUETTI portable power station is a type of LiFePO4 battery that features long service life, higher discharge efficiency, and temperature adaptability than traditional batteries. But in addition, it is capable of providing 100% of its nominal capacity without losing its most optimal performance.
Another advantage of choosing a BLUETTI portable power station is that you will never be short of power. BLUETTI has several options at your fingertips with which you can increase the capacity and power of your battery. So you can connect your phone, your computers, your fridge, your appliances, and even your whole house!
How to calculate the capacity of a solar battery?
Now that you know the advantages of batteries for solar panels and why you should install them, let's calculate what capacity you need for the solar battery you are going to buy.
First of all, it is best to make a list in which you detail both the power and the number of hours a day that you usually use each of your appliances and devices. Thus, through the multiplication of both data, you will be able to determine the consumption of each device, and adding all the results, you will extract the total amount of Wh/day that you usually consume.
Next, you must multiply the usual consumption obtained by the number of days of autonomy you need to have and multiply it by 2.
Finally, you have to transform the result obtained (which we have calculated in Wh) into Ah, since very frequently, the capacity of the batteries is expressed in Ah, so you will have to divide by the voltage of the system that you are going to install (between 24V, for example).
And voila! At this point, you have already calculated the capacity that you need your solar battery to have depending on the voltage.
In short, now that you know why you should use batteries for solar panels (in addition to a solar panel), and how to calculate the capacity of the most suitable solar battery for your consumption, all that remains is for you to enjoy your self-consumption energy!
