Our Solar Collector array consists of three Heliodyne Gobi 3366
liquid solar collectors (27 square feet each) mounted on an outbuilding. These are among the most efficient thermal collectors
made. The non-toxic propylene glycol coolant cycles in a closed loop to the house where it exchanges heat with our hot water
Though much smaller than our solar PV array, our solar domestic hot water collector array can collect just as much energy,
over 20 kWh per day (88,000 BTU/day).
