Monocrystalline Solar PV Modules

Whenever only a small amount of space is available, use is generally made of monocrystalline modules. Because the silicon content of the cells is purer, their efficiency is particularly high. Around 15 % less surface area is needed than with other modules for the same output. The cell voltage is normally also slightly higher. Monocrystalline modules currently have a life expectancy of over 30 years, with the manufacturers giving a performance guarantee of over 20 years. The cells of monocrystalline modules are generally black.
