How do I know if my roof is suitable for solar panels?

A suitable roof for solar panels should have:
  • Adequate Sunlight: Unobstructed sunlight for a significant portion of the day.
  • Sufficient Space: Enough space to accommodate the desired number of panels.
  • Structural Integrity: A strong roof structure capable of supporting the weight of the panels.
  • Appropriate Orientation and Tilt: Ideally, the roof should face south (in the Northern Hemisphere) or north (in the Southern Hemisphere) with a tilt angle close to the latitude of your location. However, other orientations and tilts can still be effective.
A qualified solar installer can assess your roof during a site visit and determine its suitability for solar.

What are the different types of solar panels?

The most common types of solar panels are:
  • Monocrystalline: Made from a single silicon crystal, known for high efficiency (typically 18-22%) and sleek black appearance.
  • Polycrystalline: Made from multiple silicon crystals, slightly less efficient (15-17%) but often more affordable than monocrystalline.
  • Thin-film: Made from thin layers of photovoltaic material, lower efficiency (8-12%) but can be flexible and lightweight.
The best type of panel for your project will depend on your budget, roof space, and desired energy output.

Do I need to replace my roof before installing solar panels?

It's not always necessary to replace your roof before installing solar panels. If your roof is in good condition and has several years of life left, solar panels can be installed on it. However, if your roof is nearing the end of its lifespan or shows signs of damage, it's advisable to replace it before the solar installation to avoid the cost and hassle of removing and reinstalling panels later. A solar installer can help assess your roof's condition and advise on whether a roof replacement is necessary.

How do I maintain my solar panels?

Solar panels require minimal maintenance. Here are some basic maintenance tasks:
  • Keep Panels Clean: Clean panels periodically to remove dirt, debris, and bird droppings, which can reduce efficiency. Rainfall usually cleans panels adequately, but you might need to hose them down occasionally.
  • Visual Inspections: Regularly inspect panels for signs of damage, loose wiring, or other issues.
  • Professional Maintenance: Consider having a professional solar installer inspect your system every few years to ensure optimal performance.
