Because of the Alberta Government’s residential solar rebate program, more and more homeowners are contacting roofing companies in Edmonton for solar panel installation. While a solar array can be installed onto an existing roof, property owners who are planning a new build also have the option of incorporating solar panels during development plans. The Edmonton roofing contractors at A. Clark Roofing & Siding LP. have put together a guide to help you find out if your home or property is well-suited for taking advantage of solar energy.
The amount of energy that your system can generate will depend largely on the location of your home. Thankfully, Edmonton is one of the best places in Canada for solar power generation, with an annual daily average of 4.55 full sun hours. Alberta also tops the nation in the number of clear, sunny days. The typical solar panel system in Edmonton should be capable of generating over 1200kWh per kW.
Orientation of Proposed Array Surface
Even in an ideal location, a solar panel array must be oriented in the proper direction in order to capture enough solar energy. For homes in the northern hemisphere, a south-facing roof is ideal. Though east- and west- facing roofs do not have the potential to capture as much solar radiation, they are often still capable of harnessing enough energy to make the investment worthwhile. Your Edmonton and Sherwood Park roofing contractors will let you know if the orientation of your roof is well-suited for a solar panel array.
Roof Inclination and Pitch of Proposed Array Surface
The optimal inclination for a solar panel array in Edmonton is 53 degrees. Most roofs, however, do not have such a steep pitch. Thankfully, this is not too much of a problem. A 45- to 30-degree tilt will produce nearly identical results, while an 18-degree tilt on a south-facing roof will only see a 9% reduction in efficiency. An elevated roof rack can also be used to increase the tilt of the array. Make sure you get professional roof repair in Edmonton before opting to build any extra structures on your roof.
Percent Shading at Proposed Array Location
A solar panel array will not operate at peak efficiency if parts of it are shaded. Make sure you trim back or cut down any tall trees that are shading your roof. Other possible sources of shading include chimneys, vents, skylights, and other roof obstructions. Experienced roofing contractors in Edmonton will position the solar panels around such obstructions. If you are developing a new-build, then you have the advantage of designing an unobstructed area for the solar panels right from the get-go.
