By reversibly depositing a silver film on a transparent glass substrate, Zhao et al. demonstrate a reflectance-switchable glazing panel for solar heating and radiative cooling.
Solar Heat Gain Coefficient (SHGC) is a measure of how much solar energy passes through a window, expressed by a ratio in the range of 0 to 1.
Glass manages solar heat radiation by three mechanisms: reflectance, transmittance and absorptance. These are defined as follows: Reflectance – the proportion of solar radiation
By connecting the cavity of a double pane window to a water-flow circuit, absorbed solar heat at the window glasses can be readily removed by the water stream. The water

The Southern African solar container market is experiencing significant growth, with demand increasing by over 420% in the past five years. Containerized solar solutions now account for approximately 38% of all temporary and mobile solar installations in the region. South Africa leads with 45% market share, driven by mining operations, agricultural applications, remote communities, and construction site power needs that have reduced energy costs by 60-70% compared to diesel generators. The average system size has increased from 40kW to over 250kW, with innovative container designs cutting transportation costs by 65% compared to traditional solutions. Emerging technologies including bifacial modules and integrated energy management have increased energy yields by 25-35%, while modular designs and local assembly have created new economic opportunities across the solar container value chain. Typical containerized projects now achieve payback periods of 3.5-5.5 years with levelized costs below R1.40/kWh.
Containerized energy storage solutions are revolutionizing power management across South Africa's industrial and commercial sectors. Mobile 20ft and 40ft BESS containers now provide flexible, scalable energy storage with deployment times reduced by 70% compared to traditional stationary installations. Advanced lithium-ion technologies (LFP and NMC) have increased energy density by 40% while reducing costs by 35% annually. Intelligent energy management systems now optimize charging/discharging cycles based on real-time electricity pricing (including Eskom time-of-use tariffs), increasing ROI by 50-70%. Safety innovations including advanced thermal management and integrated fire suppression have reduced risk profiles by 90%. These innovations have improved project economics significantly, with commercial and industrial energy storage projects typically achieving payback in 2.5-4.5 years through peak shaving, demand charge reduction, and backup power capabilities. Recent pricing trends show standard 20ft containers (250kWh-850kWh) starting at R1.6 million and 40ft containers (850kWh-2.5MWh) from R3.2 million, with flexible financing including lease-to-own and energy-as-a-service models available.
