In optimum solar power production conditions, you may not need microinverters. However, if you have shading problems, microinverters will prove their worth. With regular inverters, if a part of your solar panels is shaded, you will receive as much power as the shaded solar panels produce. If you install microinverters, the shaded solar panels will not affect the production of the other panels. Microinverters will ensure that your unshaded solar panels continue producing at their optimum and the power they generate is used to power your home. The shaded panels will still generate power at lower efficiency.
