This publication was last reviewed and confirmed in 2023. Therefore this version remains current. This document specifies requirements of appearance, durability and safety, test methods and designation for laminated solar photovoltaic (PV) glass for use in buildings. This document is applicable to building-integrated photovoltaics (BIPV).
In solar applications, reflectance is best quantified in terms of solar-weighted reflectance, since not all parts of the solar spectrum have equal amounts of energy. So weighting a reflector’s spectral reflectance according to the energy content of the solar spectrum is proper.
PV modules experience reflection losses of ∼4% at the front glass surface. This loss can be mitigated by the use of anti-reflection coatings, which now cover over 90% of commercial modules.
A group of experts in the field of optical mirror reflectance characterization has been working together as members of Task III to create this document of a reflectance measurement guideline for laboratory measurements. This document does not include guidelines for field measurements in solar plants.
Solar-weighted reflectance Solar weighting of the reflectance parameters is calculated with the currently valid standard solar spectrum ASTM G173 for direct irradiance and the appropriate Air Mass (i.e. for Europe and USA it is AM 1.5). Solar weighting is performed according to the equations provided in chapter 7 and Annex B .
The global industrial and commercial energy storage market is experiencing explosive growth, with demand increasing by over 250% in the past two years. Containerized energy storage solutions now account for approximately 45% of all new commercial and industrial storage deployments worldwide. North America leads with 42% market share, driven by corporate sustainability initiatives and tax incentives that reduce total project costs by 18-28%. Europe follows closely with 35% market share, where standardized industrial storage designs have cut installation timelines by 65% compared to traditional built-in-place systems. Asia-Pacific represents the fastest-growing region at 50% CAGR, with manufacturing scale reducing system prices by 20% annually. Emerging markets in Africa and Latin America are adopting industrial storage solutions for peak shaving and backup power, with typical payback periods of 2-4 years. Major commercial projects now deploy clusters of 15+ systems creating storage networks with 80+MWh capacity at costs below $270/kWh for large-scale industrial applications.
Technological advancements are dramatically improving industrial energy storage performance while reducing costs. Next-generation battery management systems maintain optimal operating conditions with 45% less energy consumption, extending battery lifespan to 20+ years. Standardized plug-and-play designs have reduced installation costs from $85/kWh to $40/kWh since 2023.
