What is the Difference Between Mono Solar Panels and Poly Solar Panels in Aesthetics?
Many people prefer the look of monocrystalline solar panels. This is due to their black color, which makes them more discreet and allows them to better match the roof of the house versus the dark blue polycrystalline solar panels.
Although this aspect does not concern the operation or performance of solar panels, it is not trivial. Remember that the lifetime warranty for solar panels is 25 years and their lifespan is 40 years. Making the right choice from the start is, therefore, essential because 25 years is a long time!
The image below shows the color difference between the two types of solar panels.
