During winter months , solar electric cells loose 40 to 60 %of their production capacity due to snow loads.

Lumens = Wattage
Wattage = Energy

If lumen available > then defrost load

Continue defrosting

Energy loss

E calculation

Decision

Operation cost

CASE STUDY

We can now use the power of the sun to remove the snow from the cells .....we do so only if the defrost can use less energy than is available....

The beauty of this system is the low cost of operation.....once installed there are no added cost....
