2, 2002: Clearing snow off the collectors
Well,
I've learned 3 ways of getting the snow off the collectors
and
PV panels!
1>
On sunny mornings, wait for the night's accumulation to melt
off,
and lose maybe 1-2 hours of sun:
2>
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:
3>
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!
