Monocrystalline or polycrystalline solar panel, which are best?

There are some differences in Monocrystalline (Mono) and Polycrystalline (Poly) solar panels. These differences don’t necessarily mean that one is better than the other but Mono solar panels are denoted as being a better technology in the ability to create a larger efficiency out of the cells of the panels. What this means is that if you had 2 solar panels with the same footprint (Size, width and length ) a mono solar panel can have a cell efficiencies of 20% and higher and poly solar panels are more likely to be around 19% of less. To put into a wattage, difference a mono panel could be up to 320 watts and Poly solar panels closer to 275 watts.

As a guide only as there is not a golden rule mono solar panels are more likely to have a lower Temperature co-efficient then poly panels allowing for less loses then poly panels in warm conditions. This however is only as relevant as the quality of the manufacturer, As I would recommend a Poly panel from a reputable solar compony over a mono solar panel from a lesser known solar company.
