The macro-spatial management is constituted of 5 distinct blocks: Installed photovoltaic systems and types of application; Description of type, operacional situation, fault and model of all the components of the installed photovoltaic systems; Maintanance and training centers; Phase of installation according to PRODEEM and Infrastructure of transmission lines, roads and airports. Fig. 3 shows the […]

The geometry of polymeric collectors differs from standard flat plate collectors due to material properties, the mentioned production methods and the resulting degrees of freedom in design. Various approaches to design a polymeric collector are under discussion. Mechanical stresses occur during operation and stagnation due to thermal expansion and external loads on the collectors. These […]

The vacuum tube collector implemented and simulated in OptiCAD was also investigated experimentally at the outdoor test facility of the “Test Centre for Solar Thermal Systems (PZTS)” at the Fraunhofer ISE according to the guidelines of EN 12975-2. The tests include the measurement of the optical efficiency p0 and the IAM-values in the longitudinal and […]

Influences of climate, load profile and energy storage on the optimum inclination and orientation for thermal and photovoltaic solar energy collectors Brian Norton Dublin Energy Lab Dublin Institute of Technology Dublin, Ireland president@dit. ie Abstract Climatic and operational factors influencing the optimal orientation of solar energy, primarily photovoltaic, collectors are discussed in the context of […]

S. Thomas* and P. Andre Department of sciences and environmental management, University of Liege 185 Avenue de Longwy, 6700 ARLON, Belgium Corresponding Author, sebastien. thomas@ulg. ac. be Abstract To minimize environmental impact and CO2 production associated with air-conditioning system operation, it is reasonable to evaluate the prospects of a clean energy source. The targets of […]

The variation in measured hot water use was also investigated on a daily basis to examine a possible difference between different days of the week. The results are found in Figure 6 for two different months the two years of available data. The trend is similar for both years and the variation between different days […]

The tested aluminium ICS-SWH was designed and manufactured with 3mm thick aluminium sheets incorporating fins to improve the thermal efficiency and structural stability of the heater. The water tank was placed in a hard wooden box insulated with layer of fibre glass wool on all sides and bottom as shown in Figure 1. A gap […]
