INTRODUCTION For evaluation and comparison of solar collectors, many factors need to be considered: collector thermal performance and costs, lifetime of the collectors and decrease of collector performance due to aging. The thermal performance of a solar collector is fairly easy to assess.
What is the thermal performance of a solar collector?
From 2002 to 2007 the thermal performance of solar collector has been increased by 29%, 39%, 55% and 80% for a mean solar collector fluid temperature of 40 ̊C, 60°C, 80°C and 100°C respectively. The increase of thermal performance is more significant for an increased solar collector fluid temperature.
What determines the efficiency of a solar collector?
The efficiency of a solar collector depends on the ability to absorb heat and the reluctance to “lose it” once absorbed. Figure 7.1.1 illustrates the principles of energy flows in a solar collector. Fig. 7.1.1. Principle of energy flows in a solar collector . Temperature of the ambient air.
Which type of collector is used in solar power plants?
This type of collector is generally used in solar power plants. A trough-shaped parabolic reflector is used to concentrate sunlight on an insulated tube (Dewar tube) or heat pipe, placed at the focal point, containing coolant which transfers heat from the collectors to the boilers in the power station.
