Those solar panels used for residential purposes range from 150 watts to 370 watts per panel depending on the panel size efficiency and cell technology.
Size of solar panels in mm.
Take these factors into account.
Length and width although length and width varies slightly most companies are manufacturing solar panels in standard sizes.
If you have a small or odd shaped roof solar panel size is an important consideration when deciding on the size of a solar system.
