What is the Difference Between the Mono Solar Panel and Poly Solar Panel in Performance?
The efficiency of a solar panel is the ratio between the amount of energy it collects compared to the amount of energy it produces, the rest is lost in heat. An efficiency of 20% means that 20% of the solar radiation is transformed into electricity and that the missing 80% is transformed into heat. The higher the efficiency, the greater the amount of electricity produced.
That said, monocrystalline solar panels perform better than polycrystalline solar panels due to the fact that monocrystalline solar cells are composed of a single crystal rather than a conglomerate of crystals, which increases their spectral response and thereby their energy production.
Concretely, the efficiency of monocrystalline solar panels varies between 16 and 24% while that of polycrystalline solar panels varies between 14 and 20%. That means that on an equal surface, monocrystalline solar panels are more efficient. These panels are often suggested for those whose space is a limiting factor.
Another great advantage of monocrystalline solar panels is that the crystal purity of their cells means that their production starts earlier and stops later than a polycrystalline solar panel. Not only being more efficient, but this type of panel will also have a longer energy production period than that of a polycrystalline solar panel.
