Solar film power generation umbrella

How does a solar umbrella work?

The system relies solely on radiative coupling using a photo-thermal conversion device that comprises a selective solar absorber and a blackbody emitter. Since this photo-thermal device shields the water in an evaporation pond from direct sunlight, we refer to it as a ‘solar umbrella’.

Can a photo-thermal umbrella be used in a solar still?

Another potential application of the photo-thermal umbrella is in solar stills where the vapour generated can be condensed to produce drinking water for off-grid communities. The design simplicity lends itself to a scalable solution for the sustainable management and disposal of wastewater.

Can photothermal umbrella be used for evaporation pond simulations?

Both the lab-scale prototype and real evaporation pond simulations were performed using radiation in participating media, and spectral properties of the photo-thermal umbrella were used as inputs along with relevant boundary conditions (Supplementary Note 5).

Can a solar umbrella enhance evaporation from concentrated brines?

Since this photo-thermal device shields the water in an evaporation pond from direct sunlight, we refer to it as a ‘solar umbrella’. We designed a lab-scale prototype to experimentally demonstrate the potential of the solar umbrella to enhance evaporation from concentrated brines.

How much power can be generated by solar-energy-harvesting sub-module?

Besides, theoretical and simulation results show that the annual power generation of the solar-energy-harvesting sub-module, wind collection sub-module and entire WPPGS system installed on all highways in China mainland can be up to 155 GWh, 201 GWh and 356 GWh, respectively.

What is HfG and qsolar?

where \ (\dot m\) is the water evaporation rate, hfg is the latent heat of vapourization and qsolar is the incident solar flux.
