How to install photovoltaic panels on a roof?Photovoltaic panel installations in roofs with different formats. PV modules can be placed horizontally or at an angle on flat roofs (Bayod-Rujula et al., 2011). In sloped roofs, PV modules are generally applied at the same inclination angle as the roof, and placed in parallel to increase the system efficiency.
