As the world faces an increasingly urgent climate crisis, more and more people and businesses are turning to renewable energy sources like solar power. The global solar photovoltaic capacity has increased by 632 gigawatts from 2000 to 2019, with over 100 gigawatts added in 2019 alone. Switching to renewable energy reduces carbon emissions and can help you save money and gain more control over your energy usage. Installing solar panels on a flat roof is a common option for homeowners and businesses. This article will discuss what you need to know before making the switch.
Can You Install Solar Panels on a Flat Roof?
Yes, you can install solar panels on a flat roof. Flat roofs can be a great source of direct sunlight, making the investment in solar panels worth the effort. However, some allowances need to be made to prevent the panels from shading each other. The panels must be placed away from the parapets or perimeter walls, and the extra area required must be considered. Additionally, flat roof systems often rely on ballast to protect the panels against wind and stormy weather, which can add to the load-bearing needs of the roof. Automated panels that adjust their angles according to the sun’s position can significantly improve energy efficiency. As long as you have a qualified installation engineer, you can create a solar array that functions effectively, regardless of your requirements.
The Benefits of Installing Solar Panels on a Flat Roof
Switching to solar power can significantly lower your energy bills and provide you with a short- to long-term income stream. It also allows you to work without relying on the main electricity grid and gives you with a more durable energy source. Installing solar panels on your flat roof can also help save the planet by providing an eco-friendly approach to energy and may even enhance the value of your property.
What Considerations Must Be Made Before Installing Solar Panels on a Flat Roof?
Before deciding to install solar panels on a flat roof, there are several things to consider. For example, solar panels on a flat roof generally need to be angled upwards for enough sunlight. For more sophisticated setups, the panels could be self-tilting with the basis of an automatic system that boosts the power they generate during the daytime. It is also important to consider wind loads and the risk of severe weather. The spacing between panels must be able to shade the walls of the parapet, and the risk of shading between the panels must also be avoided.
Installing Solar Panels on a Flat Roof
Installing solar panels on a flat roof is now a simple procedure a team of professionals can complete. The first step is to assess your power potential. This involves determining the number of panels you can put on your roof, including space for perimeter or parapet walls, spacing the panels to prevent shading, and avoiding any existing air conditioning units or fittings that could interfere with the panels or access to maintenance. Your installer will also check the state of your roof and make sure it is in good condition or that any necessary repairs are performed prior to the installation. Finally, you must choose between installing fixed systems that are attached directly onto your roofing or the more typical free-standing system, which uses ballast.
In conclusion, installing solar panels on a flat roof is a great way to switch to renewable energy and reduce energy bills. However, before making the switch, you must consider several factors, such as shading, wind loads, and panel spacing. Working with a qualified installation engineer can help you create a solar array that functions effectively and efficiently.
