*Cost
is for reference only, specific costs
and grant availability will vary.
Pricing in this chart must not be
considered a quote for an installed
system.
**Savings is the estimated value of
electricity saved by the system over 25
years.
A partial list of
assumptions used in the above numbers
and generation of the graphs include:
-
System is located in central
Saskatchewan (changing location
will change the angle of the sun
and the amount of sunlight
available which is determined
from historical weather data.
-
Collectors are facing south and
tilted 25 degrees. An
increased tilt will increase
system performance.
-
Collectors are not shaded.
-
Electrical water heater is 100%
efficient.
-
Electrical costs increase of
2.6% per year - contact us if
you would like to see a
different electrical increase
rate modeled.
