5 Things That Make a Roof Suitable for Solar Panels
One of the first steps in solar panel installation is figuring out whether you have the best conditions for a rooftop system. Although you can install solar panels on most roofs, some properties are set up in a way that maximises their efficiency. Here are five signs your roof is a great spot to put solar panels.
You Have a North-Facing Roof
Roof orientation determines the direction of the solar panels. In the Southern Hemisphere, it is advisable to install north-facing panels; this is the best position for solar power performance. If your roof does not face north, it is okay—you can still generate a significant energy yield.
Your Roof is Made of the Right Material
In Australia, residential roofs are typically made of tin or tile. Of the two, tin is the better fit for solar power systems. It is easy to drill into, making installation straightforward and affordable.
Tile roofs can complicate installation a little—when installing solar panels on a tile or terracotta roof, there is a chance that the tiles would break or crack during drilling. Rubber, metal, and clay tiles are also favourable—if your roof is made of any of these, it will be easier to install solar panels on it.
Your Roof is at an Optimum Pitch
If your roof is ten degrees above the horizontal pitch, it is a great place to mount solar panels. At this angle, the roof is unlikely to accumulate dirt and rain, which means better energy absorption and generation for the solar cells. While you cannot change your roof’s angle, you can modify it for your solar panels. For example, your solar installation company can help you calculate the best angle for your modules and install tilt frames that can improve your system’s efficiency.
Your Roof Has the Right Dimensions
Solar panels are relatively light at an average of 10 and 11 kg per m2, with a complete configuration weighing approximately 15 to 20 kg per m2. However, an average system would need 6.6 kW, which translates to 18 panels. The more space on your roof, the better—however, you still need to have it assessed before the installation.
Besides the size and strength of your roof, you must also consider its lifespan. Typically, roofs last at least 20 years, depending on the material. If you have ten to 15 years left on your roof’s lifecycle, you do not need to replace it before installing solar panels. Otherwise, the engineers installing the panels can build frames to ensure that the roof can support the system.
Your Roof Isn’t Under a Shade
Solar panels function well under direct sunlight. If tall trees, shrubbery, or buildings surrounding your property causes shading on your roof, you need a different approach to installing solar power. If you can’t cut down the trees or trim the shrubs, choose microinverters over traditional inverters to maximise your panels’ performance.
Conclusion
Solar panels are an excellent long-term investment for any property. Besides reducing your carbon footprint, solar power helps you save on electric bills. When considering this energy source, consult a solar installation company to determine if your roof is suitable for solar panels.
