Performance of Solar Collectors

2009
Chapter 4 deals with the methods to determine experimentally the performance of solar collectors. It outlines the various tests required to determine the thermal efficiency of solar collectors. Initially collector thermal efficiency measurement is presented and the effect of flow rate, collectors connected in series, and the standard requirements of ...

Testing of Solar Collectors

1986
The parameters which determine the performance of a collector are the operating temperature, fluid flow rate, solar insolation, orientation, tilt, time of the day, wind conditions, outdoor temperatures, clearness of the sky etc. Due to large variations in these parameters, the performance of these systems used to be often expressed in an arbitrary ...

A liquid solar collector

Solar Energy, 1987
Abstract A study is reported here of the feasibility of using a mixed solution of dyes as a substitute for a solid selective surface. The criteria for the choice of compounds were fast photothermal conversion and stability. As a result of a preliminary assessment of the photoconversion capability of such a composite system, a collector was designed ...

Solar Thermal Collectors

2016
Solar thermal collectors are used to heat up a fluid, generally water or a mixture of glycol and water depending of the configuration of the solar thermal system. They are adopted for many applications in both industrial and residential sectors. Many typologies exist in order to comply with heterogeneous needs. All have a common operating principle: to

Anatomy of a solar collector

Refocus, 2006
Solar collectors have a history stretching back nearly 120 years. Yet, taking advantage of new materials and manufacturing processes, they continue to develop to more effectively satisfy the requirements of many diverse applications. With larger scale manufacturing and more installers, in many markets their installed price continues to fall.

Solar Thermal Collectors

1983
The solar collector is the main component of a solar system. It transforms radiant energy from the sun, in the spectral range 0. 3 – 3μm, into usable heat (Fig. 1). The density of fluxes involved is low, at a maximum of the order of 1 kW/m2 (1000 times less than in the case of nuclear reactors). Heat losses depend essentially on temperature levels.
