An alternative method of heat extraction from salt gradient solar ponds to solar collector is investigated with the aim of night operation for solar chimney power system. Some details of the combined power system integrated with solar ponds and solar chimney power system are also provided. Using...

Most conventional solar thermal radiation concentrators have some sort of symmetry which allows them to concentrate solar thermal energy for their operation. We report a new system that utilises the symmetry of a cone and a cylinder combination to simulate the concentration of solar radiation on...

Solar radiation data provide information on how much of the sun's energy strikes a surface at a location on the earth during a particular time period. These data are needed for effective research in solar-energy utilization. Due to the cost of and difficulty in solar radiation measurements and...

The tilt angle of a solar energy system is one of the important parameters for capturing maximum solar radiation falling on the solar panels. This angle is site specific as it depends on the daily, monthly and yearly path of the sun. The accurate determination of the optimum tilt angle for the...

In this paper we present a prototype for a new type of solar thermal collector designed for architectural integration. In this proposal, the conventional geometry of a flat solar thermal collector is changed to a curved geometry, to improve its visual impact when mounted on a building facade or...

The problem of flat plate solar energy collector with water flow is simulated and analyzed using computational fluid dynamics (CFD) software. The considered case includes the CFD modeling of solar irradiation and the modes of mixed convection and radiation heat transfer between tube surface,...

The performance analysis of a 190 kWp solar photovoltaic power plant installed at Khatkar-Kalan, India, is carried out. The final yield, reference yield and performance ratio, are found to vary from 1.45 to 2.84 kWh/kWp-day, 2.29 to 3.53 kWh/kWp-day and 55–83% respectively. The annual...

A 3D numerical model for flat-plate liquid solar collectors has been developed. This model is envisioned for predicting the efficiency curve of the collector, for which the different heat transfer mechanisms involved are simultaneously taken into account: solar radiation absorption, transmission...
