‘Solar battery’ tested in Fairbanks building
The Fairbanks-based Cold Climate Housing Research Center is turning to the sun for warming a new 7,000-foot building addition.
The Fairbanks Daily News-Miner reports the center is testing a heating system that will use a buried 25,000-gallon water drum heated by solar panels as a solar battery.
Center research engineer Bruno Grunau says 16 2-by-6-foot solar panels will heat the water in the tank as high as 180 degrees in summer.
Tubes filled with glycol will transfer heat from the solar battery into the building.
The donated tank was lowered into the ground Wednesday.
The system will get a full test next winter when the solar energy is minimal and the building will be heated by what’s stored in the tank.
BP donated $70,000 for the project.
