Половин панели като модерно решение за засенчване ✨

A photovoltaic power plant consists of modules that are usually connected in series. In this case, the performance of the entire chain is affected by the weakest link – if one panel is shaded, the current in the entire series is reduced.

Any shading leads to a decrease in photovoltaic performance, but if it is significant (e.g., it covers key parts of the panel), it can reduce electricity production by tens of percent. This is then reflected in a longer return on investment.

We divide shading into two main categories:

• Hard shading: caused by solid objects (e.g., a chimney or neighboring building). It has clearly defined edges and can activate bypass diodes, which mitigate its impact.
• Soft shading: caused by scattered light from moving branches, distant trees, or clouds. This type of shading does not usually activate bypass diodes, which means that the reduction in performance is transferred to the entire string of panels and can cause higher losses.

How to deal with photovoltaic shading
When designing a photovoltaic system, it is essential to thoroughly analyze possible shading. We recommend using professional shading simulations to optimize panel placement and minimize power losses.

One modern solution for reducing the impact of shading is the use of half-cut panels. These panels are divided into two independent halves, which means that if one part is shaded, the other can still generate energy efficiently. This reduces losses compared to conventional panels.
