Use DC optimizers for shading!

For instance, putting the power converters close to the panels makes it possible to optimise the yields from individual solar panels or from two connected ones, which can produce up to 30 percent more capacity.

Because the panels are no longer connected as strings, negative effects from shading, manufacturing tolerances or the different orientation of the solar panels can be dealt with much better.

Connect different solar modules

Solar facades are often very fragmented or a rooftop generator consists of small, isolated or different panels. In that case, the DC optimisers convert the DC voltage from the panels to a specific value. All optimisers are then connected in a string, which in turn is hooked up to the inverter. All it still does is the DC-AC conversion. MPP tracking or safety electronics are integrated within the thin DC optimiser.

Panels may be smart, too

So-called smart panels already have the DC electronics included as part of the panel connector. Utilising DC optimizers considerably reduces the planning effort in the case of challenging roofs or solar facades. If they get disconnected from the inverter, each panel is immediately switched off. This significantly increases the safety of the installation in case of accidents or damage. (HS)
