Construction of Collector
The glass is sealed in the collector frame with EPDM and rubber. EPDM is used for sealing and it
is resistant to 150˚C and the aging effect of the sun. Silicone is applied between the EPDM and
glass. Regular rain cleans the glass. In locations with low rainfall, the glass must be cleaned. It
can be cleaned by ordinary cleaners and water. It should be noted that, the cleaner the glass, the
more efficient the collector.
