Due to an increasing focus on sustainability, rising energy costs, and net zero targets, more and more businesses are considering onsite roof top solar installations. A major consideration is understanding if your commercial or industrial rooftop is feasible for on site solar.
Although each system is uniquely designed based on your commercial requirements and space available, it is worth being made aware of key factors that may affect the suitability of your roof for solar.
Roof Condition and Age
Solar panels typically last 30 to 40 years, so it’s important to ensure that the roof can support them for that duration. It’s advisable to avoid installing on sections with asbestos, as these will need to be replaced during the lifespan of the solar system.
If your roof requires major repairs or replacement, this could be a great time to consider installing solar panels as well, allowing you to benefit from economies of scale by combining both projects.
Size and Availability
Many roofs have obstacles, such as vents and generators, that are integral to the building’s operations and cannot be removed. Additionally, some roofs may be quite small relative to the energy consumption within the building. These factors will significantly influence the final size of the solar system and the proportion of onsite energy that can be sourced renewably after installation.
If your roof space is insufficient to support onsite solar, consider exploring nearby land for potential solar installation or look into other renewable energy solutions, such as corporate Power Purchase Agreements (PPAs). The highly experienced PowerGreen team can support your business to do this.
Shading
If there are large parapets, structures blocking sunlight, or overhanging trees that cannot be trimmed, it may be wise to avoid placing solar panels in those areas, especially if you have other suitable spaces.
Roof Structure
The roof’s shape and structure will influence both the feasibility and cost of solar installation, as well as the type of mounting system used for the panels. Typically, solar panels are mounted flush on pitched roofs, while flat roofs often use free-standing panels supported by a ballast system.
Ballast systems for flat roofs can raise installation costs, whereas pitched trapezoidal roofs usually involve the lowest capital investment.
The Local Environment
The presence of local birdlife, especially in coastal regions, can significantly raise the costs of cleaning solar modules and may lead to nesting beneath the panels. Several companies have identified solutions to address this issue. Some install netting above the panels to deter seabirds, while others offer guards that prevent nesting without harming local wildlife. Additionally, some PPA providers include these maintenance costs in their energy rates, alleviating one more expense for you.
