Key Takeaways:

  • Going solar is the best way to reduce energy costs and protect the environment.
  • Solar panels can be installed on commercial flat roofs if some considerations are considered.
  • Factors like the roof’s structural capacity, any potential damage to the roof, and the need to frequently adjust the panels are important when installing solar.
  • Ensure to reinforce the roof with a structural panel or additional framing, and select and install a suitable mounting system. Also, ensure that your solar panels are tilted at the appropriate angle to maximize efficiency.
  • Hiring a professional solar panel installation expert is highly recommended to ensure the best installation results.

Switching to solar is a smart choice for businesses. It’s an eco-friendly energy source that is often cheaper than traditional sources. Plus, it can help you reduce your carbon footprint and become more environmentally conscious.

The Federal Solar Investment Tax Credit (ITC) offers tax credits that make solar energy even more attractive. In 2021, the ITC provided a 26% credit on all solar energy investments. But for systems installed in the tax year 2022 to 2032, the credit will be increased to 30%! Moreover, Floridians are exempt from paying the 6% sales tax on solar energy systems.

However, property owners with flat roofs are often hesitant to go for solar panel installation because they think their roofs are too flat to receive enough sunlight. They might also believe the panels won’t stay in place. The truth is that solar panels can be used on commercial flat roofs with some modifications.

What is a Commercial Flat Roof?

Commercial flat roofs consist of several layers. Typically, this includes a base layer with drainage, insulation, and then the waterproof membrane, which is the top layer. The most common membrane used is EPDM rubber or a modified bitumen membrane. These membranes are flat, flexible, and highly durable.

Challenges of Installing Solar Panels on Flat Roofs

While flat roofs are ideal for commercial buildings, they make solar panel installation challenging. 

One of the main concerns is the lack of structural support. Because flat roofs are not designed to hold the weight of photovoltaic (PV) panels, additional supports may need to be added, which could be costly.

Additionally, flat roofs are exposed to a lot of weather during the day and temperature fluctuations due to the lack of slope. These environmental factors could cause the panels to degrade more quickly than on a sloped roof.

Since flat roofs have limited drainage, they may need to be maintained more regularly. That is to ensure that any water puddles don’t damage the panels or seep into the building. Additionally, solar panels installed on flat roofs may need to be adjusted more frequently to ensure optimal alignment with the sun.

Despite these drawbacks, flat roofs can still be used for solar energy. There are several things to remember when installing panels on a flat roof.

How to Install Solar Panels on A Flat Roof?

To install solar panels on a flat roof, you need to reinforce the rooftop with a structural panel or additional framing. It is a great way to ensure that the roof structure can handle the extra weight of solar panels and reduce the strain on the roofing system.

After reinforcing the roof, the solar panels can be installed using a mounting system compatible with the flat roof. The mounting system must include rail-free fasteners for easy installation and be able to accommodate the tilt angle provided to maximize solar energy production.

Another critical factor to consider when installing solar panels on a flat roof is the panel’s angle. Generally, the optimal angle for a solar panel to capture the most sunlight is around 30 degrees.

If you are installing on a flat roof, you will need to use a mounting system that can adjust the panel’s angle accordingly. This adjustable mount ensures that the panels are at the ideal angle to absorb as much sunlight as possible. There are various mounting materials, including rail systems, slotted rails, tilt mounts, and ballast systems; choose the one perfect for your property.

Once you have determined the correct angle for the solar panel, it is crucial to ensure the mounting system is securely attached to your roof. It can involve using heavy-duty brackets to secure the panels in place. These brackets must be made of durable material, such as galvanized steel, to ensure they can stand up against the elements.

Next, you’ll need to connect the solar panel system to the electrical grid. This is done through wires and inverters that convert the direct current generated by the solar panels into the alternating current used by your commercial property. Hiring an experienced solar panel installation contractor is recommended for an efficient and safe installation process.
