The effect of partial-shading from trees or other objects will affect the system’s overall performance. For grid-tied PV systems, the losses experienced from shading can be significantly minimized with the use of microinverters instead of using a string inverter. For off-grid PV systems, shading can be a bigger problem as users rely on harvesting every bit of sunlight. A thorough review of the site conditions, before design and installation, will ensure that the effects of shading is avoided or at least mitigated.
