A new type of solar concentrator employing a cone-cylinder combination
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 a ring containing a fluid (water). A halogen lamp is used as the source of radiation to simulate solar ...

Flat absorbers with trapezoidal cavity for Fresnel reflecting solar concentrator
The absorber is a very important component of the solar concentrating collector. The overall heat loss coefficient of the flat rectangular absorber and multi-tube absorber were studied experimentally. Both absorbers were coated with ordinary dull black paint. The heat loss coefficient was comparatively 4-11% lower in the case of round pipe absorber and increased with the absorber temperature in ...

Demonstration of a 33% efficient Cassegrainian Solar Module
Abstract The Cassegrainian solar concentrator module concept we shall describe here uses a primary and a dichroic secondary mirror to split the solar spectrum into two parts and direct the infrared and near visible portions of the spectrum to two separate cell locations. An efficiency of 32.9% (STC) is reported measured outdoors for a solar concentrator PV module using InGaP/GaAs dual junction ...

Two scenarios for a solar world economy
Solar energy using Concentrating Solar Power (CSP) technology will become the most abundant source of renewable energy. The technology and the economics of CSP are explained. An overview is given for the deployed CSP capacity, the CSP capacity which is currently being built, and the planned capacity. We make the following assumptions: (1) The learning curve for CSP technology will finally lead to ...

Solar disinfection of natural waters with modified solar concentrators
Solar water disinfection is a proven method for household purification of drinking water. Compound parabolic collectors (CPCs) have been used to enhance the inactivation rate of microorganisms. In the present study, a modified CPC with a higher concentration ratio of 1.1 was employed to further speed up the process. A large number of tests were conducted with water samples collected from ...

Alternative scenarios of the utilisation of renewable energy sources in small prefectures: a case study in Lasithi Prefecture, Greece
The sector of Renewable Energy Sources (RESs) is growing very fast, with many innovations and applications becoming a reality. The continuous reduction of natural resources has forced all policymakers to turn to alternative energy sources. The total energy (oil and electricity consumption) consumed in the prefecture of Lasithi during the years 1997?2002 in correlation with the RES exploitation ...

Exergy of solar radiation
Solar radiation reaching the ground is accompanied with radiation entropy. When the entropy production rate within any solar energy conversion device is to be calculated, the incoming radiation entropy flux has to be known. In this contribution, first it is shown how the radiation entropy flux arriving on earth is to be calculated. Secondly, the interaction between the incoming radiation and the ...

Near Term Lower Cost Solar Electric Power for US Commercial Customers
Market Opportunities The first market for PV electric power panels was for space satellites. While the single crystal cells used in these panels made these panels very expensive, this was unimportant for that market. That market emphasized reliability, not cost. As these panels came down to earth for off-grid remote applications, again the emphasis was on reliability and low maintenance, not ...
