A Study on the Performance of Flat-Plate Solar Collector with Rectangular Channels

For the cost reduction of a flat-plate solar collector, a new galvanized iron collectro plate replaced the convenctional copper or alnminum collector plates and the flow channel was also modified to a rectangular channel for a better heat transfer performance. A simple analytical model was developed and agreed well with the experimental results. The results show better thermal performance for a rectangular channel than for a conventional circular channel.
