Wagner Introduces Solar Thermal Flat-Plate Collectors

wagnerWagner Solar received its SRCC OG-100 rating for two new solar thermal collectors, the EURO L20 AR and the EURO L20 MQ AR.

An aluminum absorber sheet is built with laser welds, creating the clean appearance of a PV module.

More aluminum improves the price-to-performance ratio, with the same vacuum-applied highly selective absorber coating to maximize solar heat yield and minimize radiation losses.

The EURO L20 AR features a double-harped header/riser piping with 12 8-mm riser tubes suitable for piping up to five in a series.

The EURO L20 MQ AR is Wagner Solar Inc.’s first four-port serpentine flow pattern flat-plate collector for the U.S. market.

    We have installed the Wagner L20 AR flat Panel Collector (east & west on the roof)
    The pump/controllers are on all the time. It seems there’s no point for them to be on when there’s no sun. Can we program the controller to have them off at night?
