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.

How efficient is a solar plate collector?

Hammad reported that the solar plate collector performance which is cooled by a set of heat pipes, manufactured and designed to operate at low-temperature conditions. As a results, the efficiency of the system was fulfilled about 60%, where the value of this efficiency was equal to that of the water cooled collector.

How can a solar thermal collector achieve utmost efficiency?

High temperatures that are required to achieve the utmost efficiency can be obtained by increasing the energy flux density of the solar radiation incident on a collector. According to Lupu et al. energy efficiency of a solar thermal collector is: Cp, m, and T are latent heat, mass of plate, and temperature, respectively.

What is collector efficiency?

The collector efficiency, η, is a measure of the collector performance and is defined as the ratio of the useful heat energy gain over a time period to the incident solar radiation over the same time period. where, R is the factor to convert radiation to that on the plane of the collector.

How efficient is a solar-air collector?

The collector efficiency varies with respect to the collector material (soil type/absorber plate material and transparent cover material), location, available solar radiation and the slope of the collector. The open solar-air collector accounts for about 50% of the investment cost of a SCPP and about 30% of the overall system losses .

What is the maximum possible energy gain in a solar collector?

The maximum possible useful energy gain (heat transfer) in a solar collector occurs when the whole collector is at the inlet fluid temperature; heat losses to the surroundings are then at minimum. The collector heat removal factor times this maximum possible energy gain is equal to the actual useful energy gain .
