EspañolWhat is a Solar Cell Modules?
Individual photovoltaic modules/panels are assemblies of connected solar cells that will absorb sunlight as an energy source to generate electricity.
A group of PV modules (also known as PV panels) is connected in a broad array called a PV array to obtain the required current and voltage.
When you make up your mind to buy a solar system, you come across three types, and as a layman, it becomes challenging to understand the difference between these technologies. So let's take a brief look at these:
1. Monocrystalline solar modules
It is a solar module composed of monocrystalline solar cells.
When sunlight hits a single-crystal solar module, the cell absorbs energy and generates an electric field through a complex process. Therefore, it includes voltage and current directly used to run DC.
The panel units have a pyramid pattern that provides a larger surface area to harvest more energy from the sun's rays.
It reduces reflections, thereby increasing absorption; cells are coated with silicon nitride.
These panels have a lifespan of 25-30 years.
They can be used to exhibit more excellent heat resistance.
The electricity generated is collected by metal conductors printed into the battery.
2. Polycrystalline solar modules
Polycrystalline PV panels account for 50% of global module production.
Consists of multiple photovoltaic cells, each containing silicon crystals used as semiconductor devices. When a photon from sunlight lands on the PN junction, it transfers energy to the electrons, causing it to flow as an electric current.
Polysilicon is the most consolidated and tested photovoltaic technology.
The conversion efficiency under diffuse light conditions (such as cloudy days) is better than that of single crystal modules.
Polycrystalline cells are slightly cheaper than monocrystalline cells.
Polycrystalline has a lifespan of 25 years.
