Solar photovoltaic panels capture the sun’s ultraviolet energy and convert it into electricity. Unfortunately that energy is in DC current and your home runs on AC current, so the power has to be inverted from DC to AC. We have two primary ways to invert the power. The first is by combining all of the panels into one system and having one large inverter that handles the entire array. The second is having a small micro-inverter on each panel and inverting each one individually. We prefer the micro-inverter method because in most cases it is more efficient. The problem with a central inverter is they work based on the lowest common denominator meaning all power output is based on the lowest producing panel so if you have 20 panels and you shade just 1 the other 19 lower their output to the lowest level.
