SWRE Solar Calculator

Soiling loss is when dust or other foreign matter accumulates over the surface of solar modules.

Reduction in solar radiation reaching to the surface of solar modules caused due to nearby objects such as trees, buildings etc.

RIncidence Angle Modifier Loss: The optical energy loss is mainly due to reflections on the module glass cover, which increases with the incidence angle.

Loss occurring due to slight variations caused during manufacturing process. Default value is 1%.

Ohmic Losses in the DC & AC Cables connecting modules, inverters and BoS parts.

Losses due to conversion efficiency of inverters, external transformer, etc.

Loss in the performance of solar modules arising in the very first hours of exposition to the sun.

Loss due to accuracy of the manufacturer’s nameplate rating.

Effect of weathering of the PV Modules.

Reduction in the output of the system due to unavailability of grid.
