Polycrystalline solar panels are the union of several silicon crystals. The polycrystalline silicon cells that make up the polycrystalline solar panel are created by artificially cooling a monocrystalline cell.

What is better a monocrystalline or polycrystalline solar panel?

The most noteworthy characteristics of polycrystalline solar panels are the following: Its manufacture is faster and cheaper than that of monocrystalline panels since less mineral is used in its production process than in the transformation process of these panels.

What is polycrystalline and monocrystalline?

While single crystal silicon has circular edges in its composition, polycrystalline silicon has square edges. In addition, it has a higher tolerance to heat. This influences, above all, efficiency, with monocrystalline silicon being the one that produces the most photovoltaic solar energy.

What type of solar panel is the best?

In addition, monocrystalline solar panels are the most efficient we can find. The performance of its cells is superior to other types of photovoltaic solar panels. Photovoltaic solar panels of this type are predominantly made of monocrystalline silicon (sc-Si).

What are monocrystalline panels?

Monocrystalline technology refers to the way in which solar panels are manufactured. A solar panel is made primarily of silicon and is made up of several photovoltaic cells that are electrically connected to each other in series and in parallel.

How to calculate the number of solar panels I need?

Let’s imagine that you need a self-consumption photovoltaic kit and that you need to generate 1kW of power with solar panels, at least during the hours of maximum irradiation, simply divide that power by the unit of the panel. That is, if you have a solar panel with 300W of power: 1000W / 300W = 3.3 panels you would need.
