Green Roofs & Solar Power
The study found that the green roof's solar array generated a daily power output of 39 kW, which was 13.1% greater than that of the conventional roof . While these two buildings were in a similar location, had similar builds, and were subject to similar environmental conditions, the building with a green roof was more efficient.
This study also characterize the 24-hour dynamic thermal responses of modules and rooftops under typical weather conditions, and apply regression modeling to quantify the driving effects of meteorological factors such as irradiance, temperature, and humidity on PV power generation efficiency while comparing system-level differences.
The Role of Solar Photovoltaic Roofs in Energy
Movahhed et al. [29] used the net present value (NPV) method to study the impact of green roofs and rooftop photovoltaic panels on the energy efficiency of typical buildings, considering three types of vegetation cover and three types of commercial solar panels.
