Solar panel vs the coldJuly 29, 2015
Our research team is putting a new solar panel to the test.
The panel is made in Germany by Roth industries. It is designed to produce more solar energy, in cold temperatures than other flat-plate solar-thermal collectors because of its polycarbonate housing and thick insulation.
"Our previous research over a 17-month study on SAIT's solar lab showed that evacuated tube collectors generate about double the heat of flat-plate collectors. But we were comparing it against flat-plate collectors that were installed at a lower title," said Tom Jackman, principal investigator of the Green Building Technology Access Centre. "The flat-plate collector was not effective over the winter months whereas the evacuated tube collector generated heat every month of the year."
The Roth flat-plate collector is now installed at the same tilt as the evacuated tube collector on the roof of SAIT's Solar Lab. A direct comparison of their performance over the winter months will prove whether the Roth flat-plate collector can perform as it was designed to.
