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

To begin, it is challenging to assess the correctness of your geometry without visualizing it firsthand. Nevertheless, as a general guideline, it is advisable to treat the solar panel and the building as separate entities when modeling, treating them as distinct solids. This approach enables the application of different materials and boundary conditions to each component, facilitating a more accurate representation of the wind loading on the solar panel.

Regarding best practices for geometry creation, several factors should be considered. Firstly, ensure that your geometry is watertight, meaning there are no gaps or overlapping surfaces. This measure guarantees an accurate and error-free meshing process.

Secondly, strive to keep your geometry simple and avoid incorporating small details that are irrelevant to the analysis. Simplifying the geometry aids in managing the meshing process and minimizing the likelihood of meshing errors.

Lastly, consider employing standard geometries or parametric modeling techniques. These approaches simplify modifications to your geometry if necessary.

When it comes to meshing, there are additional considerations to bear in mind. Firstly, ensure that the mesh is adequately refined in areas expected to experience high wind loads. This refinement captures flow details and yields precise results.

Secondly, maintain a structured mesh with a consistent element size. This consistency fosters accurate and easily interpretable outcomes.

Lastly, it may be beneficial to utilize specialized meshing software tailored for computational fluid dynamics (CFD), such as ANSYS Fluent or OpenFOAM. These software packages often provide built-in meshing tools and streamline the meshing process through automation.

I hope this information proves helpful to you!
