In this paper, an analysis of a convection-powered asphalt solar collector proto-type is approached by the means of experimental trials and computational uid dynamics (CFD) simulations in order to evaluate how to optimise its design for the reduction of high urban pavement temperatures. Since the energy harvest-
One method to mitigate the solar radiation load is directed natural ventilation underneath the PV. Providing the module with an air gap that allows air to flow behind the module decreases solar panel temperature and increases the performance of BIPV. Heat is transferred by convection to the air and transported away by the airflow.
An air convection solar tower is a unique power generation installation that harnesses the natural convection of air to produce electricity. The basic structure consists of three main components: a large transparent

The article presents mathematical modeling of turbulent natural air convection in a heated photovoltaic solar panel. The considered problem, despite its relative simplicity, contains all the main elements characteristic of currents near the wall caused by buoyancy forces. A significant disadvantage of the algebraic Reynolds-Averaged
Installing PV modules in hot regions can exacerbate the temperature difference between the module and the ambient air, resulting in reduced electrical energy production and accelerated module degradation.
For a flat rooftop PV installation near Zurich, Switzerland (temperate climate), results show that, compared to a conventional roof, green roofs can increase annual PV energy yield, on average, by 1.8%, whereas cool roofs can increase it by 3.4%.
An air convection solar tower is a unique power generation installation that harnesses the natural convection of air to produce electricity. The basic structure consists of three main components: a large transparent collector roof, a
Deploying solar PV panels has an impact on the existing environment and urban climate given the addition of low albedo and low thermal capacity materials. This concerns the strategic PV panels implementation in the urban planning and building design considerations towards human thermal comfort.

The convective heat flux (Eq. (4)) on the back of the panel is influenced by the temperature of the air on the panel back-side, which depends on the roof surface temperature, and the heat transfer coefficient (a function of wind speed, atmospheric pressure and air density ).
This paper presented the great influenced of the cooling system in reduced PV panel temperature. A cooling system has been developed based on forced convection induced by DC fan as cooling mechanism. DC fan was attached at the back side of PV panel will extract the heat energy distributed and cool down the PV panel.
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.
The influence of downward solar panel radiative heat towards the roof surface is not considered in the modeling since it is relatively small compared to the other fluxes.
