550 Watts High Efficient Mono Photovoltaic 540W 550 W 560W Black
What is the Difference Between Mono Solar Panels and Poly Solar Panels in the Price?
Monocrystalline solar panels are often more expensive than polycrystalline solar panels since their manufacturing process is more energy-consuming and complex. Indeed, the cost per watt of polycrystalline solar panels is generally between $ 0.3 and $ 0.4 while that of monocrystalline solar panels is between $ 0.35 and $ 0.5.
However, the efficiency of monocrystalline solar panels is higher than that of polycrystalline solar panels. Although they are more expensive (and more beautiful according to many), they produce more energy. Knowing that the lifespan of a solar panel is 25 to 40 years, the additional cost is very often worth it.
