This study analyse spectral transmission of solar radiation of glass and plastics. The 8 h transmittances are higher than at 12 h and are higher in winter than summer. Methacrylate and smoked glass have the highest transmittance in UV, VIS and NIR ranges. Polycarbonate has the lowest transmittance in UV, VIS and NIR ranges.
The research shows that the transmittance of the glass thickness is less than 0.9 mm, undergone the chemical strengthening process, reaches 91-92% values in whole UV-VIS-NIR region. For comparison, results for a float type glass (3 mm) shows a value about 80% in UV-VIS radiation range and about 60% above 1000 nm. Trans- mission over [...]
Spectral transmittance of the materials in the UV band in summer at 8 solar hour on 30-July. b. Spectral transmittance of the materials in the UV band in summer at solar noon on 30-July. All materials except fibreglass showed an exponential decay of transmittance in the UVB range from 300 to 315 nm.
We found that winter transmittances were higher than those in summer and were higher at 8 h solar than at noon, possibly due to the higher summer thermal level causing the network elastomers to rotate and vibrate, intercepting most of the solar radiation incident photons.
Our photovoltaic systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
