What are the different types of photovoltaic solar panels?
First of all the first big difference is in the technology
We have the monocrystalline panels and the polycrystalline for installations on isolated sites. Eversol chooses to exclusively offer monocrystalline panels because their performance and quality is superior to polycrystalline.
However, the principle is the same for both types of panels, they convert the sun's rays captured into electricity thanks to the operation of the silica photovoltaic cells. They capture photons present in sunlight to makeElectricity supply.
Le polycrystalline panel consists of a assembly of heterogeneous cells composed from several silicon crystals of varying size and shape and oriented in different directions. These impact the performance of the panel, because the crystals will not be optimally oriented, but the performance may be sufficient in countries with very high levels of sunshine. Often these panels are recognizable by their bluish tint.
For the monocrystalline the difference is simple, it is composed of cells from a single block of silicon, the crystals are therefore homogeneous. Thanks to this feature, the panel has better performance and a black color.
Solar panels differ in relation to two other characteristics, flexible/rigid, and their power.
The flexible panels are panels that do not have an aluminum frame, so they are “flexible”. So they are lighter and portable, making it more practical to use when roaming. They lose a little performance compared to rigid panels but can meet very specific needs.
The rigid panels are arranged on an aluminum frame. This installation is preferred on large panels for reasons of deformation and therefore fragility. Often, rigid panels have a larger layer of silicon and therefore have a slightly higher efficiency. Having a frame does not mean that these panels are not transportable. In fact, they can be removed from their support whenever desired.
The power of panels
In terms of the power, which is often correlated with the size of the panel, we will not choose the same panel. To do this, we must know our needs so that the panel can give enough voltage to operate the device or recharge the battery. It is therefore important to contact an expert like our distributors in order to size your installation. It will also be useful for you to know your consumption in Watt (look at the labels of your devices).
The power of photovoltaic modules expresses himself in Watt “crest”, denoted Wc (or Wp in English). This is the maximum power that the solar panel can produce under optimal standardized conditions. In general, actual production is around 75% of peak, although this depends on weather, schedule and panel orientation. In France for example, the best orientation is an inclination of 30° due south.
