Difference between String and Array in Solar Panels

A solar panel or PV module is made up of several cells, while multiple solar panels wired in a series or parallel is called a solar array. A string consists of solar panels wired in a series set into one input on a solar string inverter. 600V / 40V = 15 maximum panels per string. Find the minimum number of solar panels per string: divide
