Cost of dc optimizer
While microinverters solve the same shading and roof orientation problems as power optimizers, they are more expensive to install. When panels are strung together, all the DC power usually gets sent along to a central string inverter. Power optimizers have several advantages over other grid-tie inverter systemslike microinverters. When installing solar panels in partially shaded areas, or when there are differing roof pitch angles to contend with, both solutions allow you to reap the maximum benefits of each individual solar panel’s contributions.
