A solar module comprises six components, but arguably the most important one is the photovoltaic cell, which generates electricity.The conversion of sunlight, made up of particles called photons, into electrical energy by a solar cell is called the "photovoltaic effect" - hence why we refer to solar cells as "photovoltaic", or PV for short.
Negative Pole
Welding can be done by using an alternating current (a.c.) or direct current (d.c.). When direct current is used the welding electrode will be connected to either the positive or negative pole.This is referred to as direct current electrode positive (DCEP) or direct current electrode negative (DCEN).

Since the negative terminal of the battery is normally considered "Ground" or "Zero Volts", a fuse in the negative lead would leave the rest of the circuit "hot" - usually Not a Good Thing. Recommended practice is to place the fuse near the positive terminal of the battery, so the whole circuit will be dead if the fuse blows.
