Measuring factors influencing performance of rooftop PV panels in warm tropical climates

Modeling the Effect of Green Roof Systems and Photovoltaic Panels for Building Energy Savings to Mitigate Climate Change

“…However, an increase in soil thickness will also increase the weight of the green roof, which may exceed the load-bearing capacity of some building roofs. In addition, the distance between PV and green roofs, which can affect PV-power production [39][40][41], cannot be set up using the current version of EnergyPlus. Therefore, this study followed the settings of Sailor [20], which were based on validated data from two monitored buildings with green roofs at Portland State University, Oregon, instead of applied the optimal settings.…”

“…Osma-Pinto and Ordonez-Plata stated that green roofs can reduce the air temperature around PV panels under tropical conditions if the PV installation heights were lower than 100 cm. However, no evidence of this effect can be found if the PV installation heights were greater than 100 cm [40]. Osma et al indicated that PV system with separation height of 0.5 m was higher when compared with 0.75 m in their experimental site in Columbia [39,41].…”

“…Heusinger et al discovered that maintenance, such as irrigation, played a vital role in the performance of green roofs [27]. In recent years, a few studies [18,[31][32][33][34][35][36][37][38][39][40] have suggested the integration of green roofs with a solar PV system. In a typical PV-green roof system, PV panels are mounted above the layer of green roof with reasonable distances and angles (Figure 1b), which allows growing room for the vegetation without blocking light to the solar cells.…”

“…In a typical PV-green roof system, PV panels are mounted above the layer of green roof with reasonable distances and angles (Figure 1b), which allows growing room for the vegetation without blocking light to the solar cells. The potential symbiotic relationship between PV panels and green roofs had been proved by many studies [31,[35][36][37][38][39][40], which suggested that integrating PV with green roofs can provide reciprocal benefits to both PV electrical production and green roof communities [36]. However, climate conditions, types of vegetation species on green roofs, and the installation heights of PV panels can affect this symbiotic relationship.…”

Impact Evaluation of Grid-Connected PV Systems on PQ Parameters by Comparative Analysis based on Inferential Statistics

“…The average solar irradiance is 4.9 kWh/m 2 /day, which varies between 2.0 kWh/m 2 /day and 7.6 kWh/m 2 /day. The wind speed in the UIS campus varies between 1.0 and 1.5 m/s [22]. This PV system has a capacity of 9.8 kW and is formed by 37 PV panels (255-270 W) and 37 Enphase M250 microinverters.…”
