Which Collector the Efficiency Is Maximum?

In tests, Absolicon solar collector has shown to have an efficiency of 76.6%. This is the highest number ever achieved for a small parabolic trough

The process is economical and, for heating the pipe, thermal efficiency ranges from 60-80%. The overall efficiency from collector to grid, i.e. (Electrical Output Power)/(Total Impinging Solar Power) is about 15%, similar to PV (Photovoltaic Cells) but less than Stirling dish concentrators.

. The Absolicon T160 Solar Collector, manufactured in Härnösand, has received tremendous results in Switzerland!

What is collector efficiency?

The collector efficiency is the ratio of the useful energy gain to the incident solar energy over a particular period of time.

Which collectors have the highest and lowest maximum efficiency values respectively?

The V-corrugated collector was found to be most efficient, while the flat-plate collector was the least efficient.
