Greetings! I'm here to assist you with any inquiries you may have regarding wind loading on solar panels installed on rooftops.

To start off, it's challenging to assess the accuracy of your geometry without visualizing it directly. However, as a general guideline, it is advisable to treat the solar panel and the building as separate entities in your analysis. This approach allows you to assign different materials and boundary conditions to each component, enabling a more precise representation of the wind loading on the solar panel.

When it comes to creating the geometry, there are a few best practices to consider. Firstly, ensure that your geometry is watertight, meaning that there are no gaps or overlaps in the surfaces. This step guarantees an accurate mesh and minimizes errors.

Secondly, it is advisable to keep your geometry as simple as possible, avoiding unnecessary intricate details that do not contribute to the analysis. This simplification aids in managing the meshing process and reduces the likelihood of errors.

Lastly, consider using standard geometries or parametric modeling techniques, as they facilitate easier modifications to the geometry if required.

Regarding meshing, there are a few key points to keep in mind. Firstly, ensure that the mesh is fine enough in areas where high wind loads are anticipated. This finer mesh captures the flow details and provides accurate results.

Secondly, strive for a structured mesh with consistent element sizes throughout. This consistency enhances the accuracy of the results and facilitates interpretation.

Lastly, you may want to consider employing specialized meshing software designed for computational fluid dynamics (CFD), such as ANSYS Fluent or OpenFOAM. These software packages offer built-in meshing tools and automation features that streamline the meshing process.

I hope this information proves helpful to you!
