Ballasted, unattached PV systems on low-slope roofs have to meet seven conditions to comply with seismic load requirements in Section 13.6.12. For low-profile systems, the height of the center of mass of any panel above the roof surface must be less than half the least spacing in plan of the panel supports, but in no case greater than 3 feet.
An experimental study in the hot and dry climate of the United Arab Emirates found that integrated PV-cool roof systems increased annual rooftop PV yield between 5 and 10% [21], which is potentially higher than the yield from a PV-green roof system. However, the panel yield from PV-green roofs has yet to be compared to integrated PV-cool roof .
The results show that after installing photovoltaic panels, the delay performance of the roof increases by 0.5 h, the roof heat flux is reduced by 41.7%, the peak temperature of the roof is reduced by 22.9 °C, and the daily heat gain is reduced by 74.84%.
The efficiency of PV panels is a strong function of their module temperature. Under nominal conditions, for every 1 °C increase of a crystalline silicon cell module temperature, its efficiency drops by almost 0.45% [46], while for thin film modules the loss of efficiency is 50% lower [51].

How efficient is a PV roof?
The comprehensive energy-saving efficiency is about 61.06%, and the heat gain indoors is reduced by 74.84%, indicating significant energy-saving potential. PV rooftop components exhibit a significant shading effect, effectively lowering roof temperatures and reducing indoor heat.
Does roof configuration affect PV energy yield?
The roofing configuration affects the yield of PV energy. By providing a systematic method to evaluate this influence, solar energy planners can differentiate between the benefits of traditional and sustainable rooftop configurations, which is the first step towards the coupling of distributed energy and sustainable building systems.
Does a vegetated roof increase PV yield?
Vegetated roofs, when integrated with PV (Photovoltaic) panels, can increase annual PV yield by up to 8.3% in some cases, as shown in monitoring studies and statistical analyses in warmer climates such as Colombia, Spain, and Hong Kong. These systems are referred to as integrated PV-green roof systems.
Does temperature affect photovoltaic roof design?
The study analyzed the impact of natural convection, roof energy balance disrupted by panels, and comprehensive conversion efficiency affected by temperature on two photovoltaic roof designs and compared them with a traditional roof.
