What is the operation of Battery Energy Solar Systems?

Read on to learn the most crucial facts regarding solar batteries, which are detailed in the following article. In the event of isolated solar systems, this is a very necessary instrument. Everything you need to know about typologies, technologies, and applications is covered in detail in the following article.

What exactly are solar-powered batteries?

Batteries are critical components for solar energy systems because they are responsible for storing energy so that it can be used at night or for extended periods of time when there is no solar radiation available.

These components are also responsible for increasing the current intensity of the system above and beyond that obtained by the solar panel, hence improving the overall performance of the system. In fact, you should be aware that it is the most expensive component of your solar installation budget, and it can account for more than half of the total cost of your project.

What is the composition of the solar battery?

It is made up of one or more electrochemical cells, which are responsible for converting the chemical energy stored in the battery into electrical energy when it is turned on. In order for the battery to execute its purpose, each cell is comprised of a positive electrode and a negative electrode, as well as electrolytes that allow for the movement of ions between the electrodes, hence increasing the fluidity of the current outside the battery.

What is the process of charging solar batteries?

The photovoltaic system will collect solar radiation from the solar panels and convert it into power, which will be delivered to the installation at the time of installation so that we may make use of it ourselves. However, the excess energy that we do not use is stored in the batteries or batteries that are part of the overall system.

We can use this saved surplus during the night or for extended periods of time when it is not possible to use the photovoltaic system owing to weather conditions to generate electricity. Battery energy storage systems have a capacity for storing solar energy that is determined by the pace at which it is discharged. As a result, the bigger the Ah capacity of our battery, the greater the amount of energy that it is capable of giving to the rest of the world.

In addition, the capacity of a battery is calculated based on a variety of factors such as daily consumption, maximum power of the installation, number of days of autonomy, kind of use, and other factors.

Lead-acid batteries for use in solar energy systems!

Lead-acid batteries are the most ancient type of rechargeable battery still in use. Considering that these batteries have the capability of delivering large current intensities, their cells have a high power density as well.This characteristic, combined with their low cost, makes them appropriate for a wide range of applications, particularly in solar energy, solar kits, and motor vehicles.

After all, they have the capability of generating the high current required by starter motors to operate.Lead-acid batteries are commonly utilized because they are significantly less expensive than any other type of battery. These batteries, on the other hand, have a low energy density in terms of both volume and weight.

Because of this, if you wish to store significant amounts of energy, the battery must be extremely enormous in size. Consequently, it would not be the greatest choice for applications that necessitate the use of the scroll bar. They are typically employed across huge areas. Several types of safe food sources, such cell phone towers, hospitals, solar power facilities, and isolated electrical systems, can be stored in them.

Solar Inverters- What are they?

The solar inverter is one of the most significant components of photovoltaic installations because it allows the utilization of energy generated by solar panels. It is also one of the most expensive components. We’ll go over how it works and which model is best for your house after that.

So, what exactly is a solar inverter and how does it function?

This device is responsible for converting the energy generated by solar panels into practical energy for everyday use. Solar inverters are current converters that convert the energy produced by solar panels into useful energy for daily usage. Aside from that, the photovoltaic inverter will also optimize the photovoltaic production of the solar installation, allowing the highest possible performance to be gained from each individual solar panel of the photovoltaic self-consumption system.

In order to produce direct current, solar panels must convert solar energy into electricity. Because direct current is not suitable for electricity consumption, the solar inverter plays an important function in this situation. As a result, the current converter modifies the waveform and frequency of the incoming current, converting it into alternating current and making it usable.

Solar inverters have dimensions ranging from around 50 – 70 * 40 – 60 cm (depending on the type), making them relatively small and easy to install. In the same way, these components do not represent any form of threat to human health.

What are the traits that a solar inverter must possess?

  • Firstly, maximum transformation power: this is the most quantity of energy that our inverter is capable of converting; it can be stated both in W and in VA. Despite the fact that inverters have safety margins that are more than the indicated capacity, it is essential to select an inverter model that is appropriate for the installation.
  • Secondly, in the event of a short circuit, a network failure, or a component failure, solar inverters must be able to shut down the system and stop production. It is necessary to install a separate shutdown system if it is not possible otherwise.
  • Third, the inverter must optimize solar production regardless of whether or not there is shade or what sort of panel is installed. As a result, we must determine which inverter is the most appropriate for our needs at home.
  • Lastly, Data collection: The gathering of production data will allow us to verify that our installation is operating correctly and, if there is a problem, to resolve it.
