Is Your Roof Ready for Solar Panel Installation?
Before purchasing solar panels, its important to ensure that your rooftop is suitable for the same. In this solar panel installation guide
Here’s what to look for:
- Roof Condition: If your roof is very old or damaged then its not a good idea to fit the solar panels. You must repair your roof first so that it can sustain the solar panel’s weight.
- Roof Type: You can install solar panels on various types of roofs, including asphalt shingles, metal, and tile roofs. However, some roof types may require specialized mounting systems.
- Roof Orientation: The optimal angle for solar panels is usually between 30 to 45 degrees. This range ensures that the panels tilt to capture sunlight most efficiently.
- For flat roofs: You’ll likely need to install a mounting system that can adjust the angle of the panels.
For sloped roofs: The angle of your roof itself may already provide a good starting point, but you often adjust it to maximize energy production. - The most effective angle for solar panels is often linked to your latitude—the distance from the equator. Here’s how you can calculate the ideal angle based on your location:
Angle = Latitude + 15° (Winter)
Angle = Latitude – 15° (Summer)
- For flat roofs: You’ll likely need to install a mounting system that can adjust the angle of the panels.
