Minimizing partial shading yield losses

Shading, where even just a small part of a PV system is left out of the sunlight, can be a significant drag on the energy yield of the entire system. But as solar integrates further into our built environments and other places that don’t offer uniform flat land, it’s an issue that PV module and system designers will have to face head on. Optimizers offer one solution, but building shading resilience into the module itself can have even better outcomes, as we’ll see in this pv magazine Webinar.

Most rooftop or building-integrated PV installations have to live with some degree of shading, and many more can only be seen as viable for a solar installation once extra action has been taken to reduce the impact of shading. We’ll kick off this webinar with a demonstration from an installer – Christian Carpaij of Planeco – of the effect that shading can have on system design and energy yield potential in both rooftop and ground mounted PV projects.

We then dive into the latest technologies in PV module design, focused on building shading resilience in from the beginning. Hamed Hanifi, head of research and development at AE Solar, will share details of the module manufacturers approach, applying a bypass diode to each individual cell in the module, preventing partial shading from dragging down the entire module’s output.

We then hear about several even newer approaches to shading mitigation that are making their way through the PV research community and out to the market: Nils Klasen of M10 Solar Equipment will share an update on the company’s Shingle Matrix technology, which sees PV cells cut into strips and laid out in an offset pattern, allowing current to bypass the shaded area.

Finally, we’ll pass over to Jan Paschen, scientific researcher in the Photovoltaics Division at Fraunhofer ISE, for a look at some other approaches to module design, incorporating laser processes, that also promise big steps forward in the design of shading-resilient PV modules.
