SHIP is the acronym for Solar Heat for Industrial Processes and describes systems which provide solar heat in a factory.. A collector field heats a process fluid by means of solar radiation and a heat exchanger transfers this heat to a supply system or production process in the factory as hot water, air flow or steam.
The system achieves an efficiency of 7.78 to 8.81% at low current density region and 6.6% at high current density in converting solar energy into hydrogen. The …
Hot water production, space heating and air-conditioning are the major consumers of energy in public buildings; if their energy demand can be addressed holistically through the integration of solar collectors with public buildings, it will bring about a …
Most of electricity is produced by using coal with high greenhouse emission. Accordingly, worldwide, the most rewarding application of solar energy is when it replaces electrical …

It is possible to use a solar panel to power low voltage, direct current (DC) blowers (for air collectors) or pumps (for liquid collectors). The output of the solar panels matches available solar heat gain to the solar collector. With careful sizing, the blower or pump speed is optimized for efficient solar gain to the working fluid.
Polymer solar collector investigated in this paper is a FPC intended for heating of working fluid, in this case water. Prototype is made of individual segments 2000 mm long and 115 mm wide as shown in Fig. 1 a. Segment is made via extrusion process in a company based in Croatia from C-PVC, with a cross section as shown in Fig. 1 b. Cross …
Furthermore, the combination of solar thermal collectors and heat pumps is a more robust technology called Solar-Assisted Heat Pump (SAHP) that can improve the system''s performance and requires less electrical energy [61].Buker and Riffat studied and analyzed direct SAHP systems extensively [41].However, long-term maintenance costs …
