Expert sizing and design

We estimate the solar thermal energy for your project and anticipate the utilization by using our collectors. Sizing of the solar thermal energy system depends on several factors including: geographic location, number of solar hours, orientation of the collector relative to the compass direction and your own energy needs. 

Hot water panels only

One industrial size 4 foot by 8 foot solar panel will produce about 18,000 BTU of heat per day with approximately 6 hours of sunlight.

About 150 litres of storage is required for each solar panel. (33 Imperial Gallons or 40 US gallons)

As a rule of thumb, 1 solar panel is required for every 500 square feet of space to be heated.  This can very depending on a number of factors:

  • Climatic conditions.
  • How well insulated the building is
  • How often and how long are doors left open
  • Type of fuel (natural gas, coal, oil, propane or electric)
  • Is water being heated as well as the building
  • How much hot water is used.
