January 2, 2002: Clearing snow off the collectors
I've learned 3 ways of getting the snow off the collectors
and PV panels!
On sunny mornings, wait for the night's accumulation to melt
off, and lose maybe 1-2 hours of sun:
Use a broom to brush snow off the lower half of the
collectors, then go reach out the window and brush off the
PV panels and the tops of the collectors:
Disconnect the PV panels and hook a car battery (or 12VDC
power supply) to the 2 circulation pumps. The heat exchanger
now works in reverse, pumping stored 70F hot water from the
tank into the collectors. Works like a charm on those heavy
ice days when the outside temperature is below zero!
Although at a cost of some propane!
