The Murphy and Feyen families are doubling the size of their original solar collector, and soon the ““sun snagger”” will cover the entire south-facing barn roof. The extra heat gathered by the enlarged collector will be stored in buried pipes to provide more warmth in the farrowing house on cloudy days. The hot air will run a solar grain dryer as well!
John Feyen and Sharon Murphy install support ribs for the second half of the collector. Note how the pig-raisin’ people have cleverly — and economically — used the original roof of the barn as part of their collector! The lumber comes from trees cut on their own land, and the ductwork is made of inexpensive pressed board, so the biggest material expense was for the fiberglass resin skin (the film used in the first collector cost $270).
