Types Of Solar Panels

Polycrystalline solar panels are less wasteful during production. They loose less efficiency at higher temperatures then mono panels.

The disadvantage is slightly less efficiency. The look is less attractive then mono or thin film.

Monocrystaline solar panels have the highest efficiency rates since they are made out of the highest grade silicon. They are more of a uniform look vs. the polycrystalline panel. If your roof space is limited mono is the way to go.

The disadvantage of the monocrystalline is the higher price and the electricity output degrades at higher temperatures. They do need full sunlight to be efficient. So this panel is best for South facing roofs and areas with little cloud cover.

Thin film solar panels are the least efficient per square inch but they are very pleasing to the eye. They produce electricity even in shaded/overcast conditions. The output is not so sensitive to high temperature.

If roof space is limited then thin film is not the right choice. Otherwise thin film is the way to go for most people.  There is a good reason why over 80% of solar farms in Europe use thin film.
