Workshop - Oversizing of PV inverters: how to evaluate where to apply

A recurring theme in the discussion groups on solar energy projects is the oversizing of PV inverters. Let's unravel the mysteries in this workshop.

First, we need to understand how the inverter reacts when the PV power at his input exceeds its working capacity and it needs to activate its internal protection, an effect called clipping.

Next, let's look at which situations this clipping can occur and what are the associated energy losses. From energy losses, let's move on to economic losses, which represent what really matters to the owner of the photovoltaic plant.

Case studies, accurately calculated in the PV*SOL software including rapid weather variations such as passing clouds, will show the impact of parameters such as scaling factor and the local climate.

To conclude, we'll discuss in which cases oversizing might be interesting, and how to proceed when preparing a project with this proposal.
