Photovoltaic solar energy is an intermittent technology that depends directly on the presence of solar radiation, its performance is linked to other factors such as the location and ambient temperature of the site. As the surface of a photovoltaic module heats up, negatively affects its efficiency and reliability, cells lose approximately 0.5%/°C of performance when their temperature increases relative to STC. There are several strategies to improve the performance of photovoltaic modules and this research emphasizes three of them: Green roof, Water-cooling and Reflective Surface. Experimentally, the three strategies mentioned and the combination of them with respect to a base scenario are compared. The results showed that the Reflective Surface performance improvement strategies and the combination of them are optimal, increasing energy production by 9.94% and 13.8%, compared to the base scenario. Other alternatives such as Green roof and Water-cooling were considered, but only achieved increases of 1.13% and 4.62%, respectively.
