The BRC planning tool is used to support planning decisions for photovoltaic systems and only provides a non-binding recommendation.

When planning, we always assume that the strings are connected in series. We do not recommend parallel connection for an optimized system.

The most efficient solution is always displayed as the result of the simulation.
