We’ve been doing solar installations for homes for a long time in Ontario. One of the most common questions we are asked by our customers is , “How do I know if my house is a good candidate for solar?” Or, “How do I know solar can be installed on my roof?”
Well it’s easy. All you need is a quick look at your house by a solar professional – via satellite or in person. Before installing Solar on anyone’s home, we at Eco Alternative Energy first conduct an inspection of the property either through satellite imagery (first) or in person.
We basically look for :
- A good Southern, Western or Eastern exposure (although south is best, east and West roofs can still be very rewarding).
- The pitch of the roof (25-50 degrees is typically optimal).
- Any shade considerations to avoid? (trees, chimneys, plumbing stacks)
Our Solar inspectors have specialized tools to perform a shading analysis to determine if shading will be a problem for your site. Cutting back trees may be a solution and we will advise accordingly.
After determining the size of the best system for you, we can then determine your systems estimated production in kilowatt hour ’s (kWh’s) based on your roof pitch, azimuth, and shading and provide you with an fairly accurate projected return on investment. Once you have a sense of how much energy your system will generate, you can evaluate the cost of purchasing.
Installing systems smaller than 2kW may not be worth your while. If you’re trying to do the math yourself, then figure each panel as is about 5.5 feet tall by 3.3 feet wide.
We hope that was helpful! If there are any more questions you have regarding solar, please feel free to leave a comment below or Contact Us.
