How to understand a technical sheet of a solar panel?

Solar panel | A technical sheet of a solar panel is important both for you and for your client since it specifies the data of the product that is being acquired. For this reason, it is necessary that you know how they should be read and what are the most relevant data of it.

And as you know, in the photovoltaic market it is necessary that you know the characteristics of the products you purchase, because through these specifications you will be able to know the electrical and mechanical characteristics of the equipment, which are essential.

Despite its importance, it is not usually talked about very often, for this reason, we decided to do this article where you can find out what a solar panel data sheet is, the information you can get from it, and how it should be read. We invite you to join us.

How to understand a technical sheet of a solar panel

1. What is a technical file?

A technical sheet of a solar panel is an informative document where different data and information are found, such as the electrical and mechanical characteristics of the equipment, as well as the summary of its operation, certifications, etc.

These sheets are useful for the different departments of your company to keep in mind the characteristics of the photovoltaic module, such as the commercial area, logistics, technicians, and installers, among others.

2. Why is it important?

The technical sheets are important, since the information obtained from them helps the different departments of your company, for example, knowing how they should be handled, their method of use, and specific care, in the case of installation.

Likewise, the specifications help the sales or commercial department, because the information provided can be useful to present your potential client with the Solar Panels Castle Rock that best suit their situation.

Likewise, with the provided characteristics, you will be able to make comparisons to verify if a product is feasible for your business according to its characteristics and price.

And as the last point, a technical sheet of a solar panel provides confidence to your client, because he will be able to know the characteristics of the products he is acquiring, in addition to serving as a backup.

3. Essential elements

Now that you know more about the technical sheets and the importance they have within your photovoltaic business, you need to know the elements that you must take into account when reading or wanting to understand one.

Open Circuit Voltage (VOC)

It is the maximum voltage of a solar panel without any load connected, it is necessary to take into account that its value varies depending on the atmospheric conditions where you will carry out the installation.

Short Circuit Current (ISC)

It is the intensity of the current that the solar panel can produce when it is short-circuited, this is measured in amps.

The voltage at maximum power (VMP)

It is the voltage that the solar panel reaches when it is working at maximum power. It is important to note that the VMP varies in tandem with the IMP.

Current at maximum power (IMP)

It is important to know this value because, as you know, the intensity changes due to the fact that the solar rays do not reach the solar panel at the same angle of incidence.

Maximum power (PMAX)

The PMAX refers to the maximum power that the solar panel can supply.

Tolerance

It is the power range that the manufacturers of solar panels establish because during the manufacture of the modules there are small dispersions. 

4. How to understand a technical sheet of a solar panel

In order to correctly interpret a technical sheet of a solar panel, it is important to know the basic electrical terms such as voltage, amperage, power, energy, etc. Once you know this you will be able to understand them, since in it you should always look for these terms that help us to correctly design our system with the equipment that we are selecting.

conclusion

As we have talked about in this blog, it is important that you know know how to read a technical sheet of a solar panel because it will help you in different areas of your photovoltaic business.

But for this it is necessary to know the basic concepts, if you want to know what they are, we invite you to visit us on our blog, where you can also find more topics that will be useful to you.
