What is a critical consideration while installing roof-mounted PV systems?

When installing roof-mounted photovoltaic (PV) systems, a critical consideration is the structural integrity of the roof and the required clearances around the installation. Ensuring the roof can safely support the weight of the solar panels and associated hardware is vital in preventing structural failure. This includes evaluating the roof’s load capacity and its condition, including any potential damage or wear that could affect its ability to support additional weight.

Additionally, maintaining appropriate clearances is essential for several reasons: it allows for water drainage, prevents potential shading that could reduce system efficiency, and ensures compliance with local building codes and safety regulations. Clearances also facilitate maintenance and cleaning of the panels, which is necessary to maintain optimal performance.

These considerations directly affect the longevity, safety, and efficiency of the PV system, making them paramount in the installation process.
