Design is pretty much decided based on the tilt angle, height allowed based on the standard and number of strings on the rooftop. Accurate measurements of the rooftop installation area is crucial, one mistake cost the installers as there won't be sufficient place to install the panels, thus resulting in changes in the single line diagram, string layouts and solar panel layout.

Ballasted solar PV installation can be combined with other sustainable roofing configurations such as green roofs and cool roofs (roofs with a high reflectance coating). This combination has the potential to increase the solar panel output. The vegetation of the green roof reduces the temperature below the panel, increasing the solar panel efficiency. On the other hand, the high reflectivity of the cool roof reduces the roof temperature, as well as scattering more solar radiation towards the panel. The estimated power output increase is in the range of 1 to 4%. Beyond that, these roofing configurations offer various additional benefit, including urban heat mitigation, and biodiversity enhancement (in the case of green roofs).

Ballasted solar PV installations provide adaptable energy solutions, offering scalability and flexibility to meet changing energy needs.
