6 FAQs about [Solar power generation insulation layer]
Why do solar panels need a high-reflectivity and low-emissivity insulation layer?
The surface of the insulation layer is designed with a high-reflectivity and low-emissivity material as specified in Table 8, to avoid heat accumulation under the panels that will negatively affect the PV power generation. In winter, night insulation is sufficient in preventing excessive radiative heat loss ( Fig. 13 ).

How does panel temperature affect PV power generation in other climate regions?
The panel temperature range and pattern for semi-transparent PV in other climate regions are similar to that in Osaka. Panel inside surface temperature contributes to heating and cooling load through convective and radiative heat transfer, while outside surface temperature affects the PV power generation. 4.1.2. Panel heat transfer
How do bilayer structures improve solar water generation performance?
The bilayer structures work synergistically to enhance the solar water generation performance by balancing the trade-offs between water transport rate and light-to-heat energy consumption during the water phase-transition evaporation process.
