Does solar radiation intermittency predict future photovoltaic reliability?

Using both satellite data and climate model outputs, we characterize solar radiation intermittency to assess future photovoltaic reliability.

Does future power supply influence long-term mean solar radiation trends?

We find that the relation between the future power supply and long-term mean solar radiation trends is spatially heterogeneous, showing power reliability is more sensitive to the fluctuations of mean solar radiation in hot arid regions.

Can radiative cooling be integrated with existing PV systems?

The integration of radiative cooling with existing PV systems offers a strategic solution to the inherent challenges of solar energy utilization, unveiling new PV infrastructures that can satisfy the cooling requirements of residential and commercial applications.

How does climate affect solar power reliability?

As can be seen in Fig. 1, the K distributions for larger mean values (denoted as μ and also referred to as the mean clearness index) tend to have longer left tails, which are associated with the weaker solar radiation and lower power generation. Fig. 1: Examples of climate impacts on solar radiation and photovoltaic power reliability.

How much solar irradiance can a daytime radiative cooling surface produce?

On a clear day, solar irradiance can reach 1000 W/m 2 with a diffuse component between 50 and 100 W/m 2. On average the cooling power of a passive daytime radiative cooling surface has been estimated at ~100-150 W/m 2.

Can simultaneous radiative cooling and solar power produce electricity without mutual interference?

However, a significant gap persists in realizing concurrent radiative cooling and solar electricity production, which signifies an ongoing challenge in harnessing these dual capabilities without mutual interference, a critical advancement necessary for the practical application of simultaneous radiative cooling and solar power generation.
