Customer ServiceThe investigation was carried out on collectors used for a period of 10 years or more. It is expected that the estimated service life for the coating is of the order of 30-40 years in an airtight solar collector with controlled ventilation of air, while in a non-airtight collector, the estimated service life is shortened to 5-10 years.
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.

Table 1. Recent research findings on CPCs. Solar collector with dual function offers efficient space and water heating with 48.4% efficiency in autumn, and in summer it cools rooms by 2% preventing overheating. Segmented profiles on 2-D CPCs suggest lengths of < 5% for absorber circumference to achieve high (100%) flux efficiency.
The collector is tested with four mean solar collector fluid temperature levels: 22 ̊C, 40-49 ̊C, 68 ̊C and 87-89 ̊C. During the measurement, the average ambient air temperature is 14.7 ̊C. The average wind speed at the same height of the collector panel is 1.2 m/s.
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.
