A PV system designer is selecting between monocrystalline and polycrystalline modules for a space-constrained rooftop. Which module type is generally preferred and why?
-
A
Polycrystalline, because it costs less per watt
-
B
Monocrystalline, because it offers higher efficiency and greater power density per area
-
C
Thin-film, because it handles shading better
-
D
Polycrystalline, because it has a better temperature coefficient
