18 Tubes Solar Keymark Approved Vacuum Tube Solar Panels Hail Resistance

 1. Working Principle:                                                                                                                       

Heat pipe series solar collector is always connected with existing heating supply device. The selective coating inside tubes converts solar energy into heat energy and transfers heat to heat pipe via aluminum feed. The liquid (anti-freezing liquid) in the heat pipe changes into vapor which rises to the condensers. This transference of heat in the liquid creates a continuous circulation as long as the collector is heated by the sun.
