 W panels are usually nominal 12v; [[electrical:solar:panels#panel_voltage|there are also 20v and 24v panels]] one can source from the solar grid-tied market.  The higher voltages panels require a MPPT controller (see below) but tend to be cheaper per watt.
-The two main types of panel in 2018 are **monocrystalline** (//mono//) and **polycrystalline** (//poly//).  The technical details are unimportant but you will see panels described as mono or poly when you are researching.  Because of a quirk of voltage output their behavior, **poly panels are slightly better suited to PWM charge controllers**, and **mono panels((and "high voltage" 20v/24v panels)) are slightly better suited to MPPT controllers**.   These controllers are discussed next.
