The Rooftop Solar Opportunity for Warehouses

Transforming sunshine into solar energy is big business and solar panels are now a common feature on residential rooftops.  But the potential for more clean energy is growing for businesses too, particularly the vast roofs of warehouses.

DSA Structural & Civil Engineers are enabling more warehouses in London and across the UK to take advantage of solar energy and here’s their guide on the key things to consider when planning to install solar panels.

The Untapped Potential of Warehouse Roofs

A typical warehouse roof offers a vast, unobstructed roof area often with flat or gently sloping surfaces ideal for the installation of solar panels that are optimised for maximum sunlight exposure. But other than creating clean energy there is another valuable benefit – these unused spaces suddenly start saving businesses significant money, making solar panels a smart, sustainable investment for companies seeking long-term operational efficiency.

Key Things to Consider When Installing Solar Panels on a Warehouse Roofs

The priority is to assess the roofs suitability for a solar panel installation. This can happen at roof design stage for a new warehouse construction or on an existing warehouse structure. A typical roof survey will include:

• Load-bearing capacity: To make sure the roof can hold the solar panels design and mounting systems, also considering the context of additional loads such as wind uplift and snow build up.
• Roof condition: Identifying any weaknesses that could lead to failure.
• Age and materials: An older warehouse may need reinforcement or repair before installation.
• Previous modifications: Any work done previously may need changing or replacing in readiness for the solar panel systems.

If your structural engineer’s survey confirms adding solar panels is feasible, you can start requesting quotes for installation costs to secure the optimum price. Often there are various grants and incentives linked to solar panel installation so it’s worth researching latest information, locally and nationally.

Installing Solar Panels on Warehouse Roofs

DSA provide these practical steps to follow when installing solar panels on commercial buildings:

• Hire a qualified structural engineer or surveyor: A professional assessment of the roofs integrity and load capacity is essential to confirm if it can safely support the solar panel installation, including the type and weight of mounting equipment.
• Evaluate roof reinforcement options if needed: DSA have encountered many instances where the roof survey has discovered that a warehouse roof is not suitable in its current state, but this doesn’t necessarily mean solar panels can’t be installed. If extra support is needed a structural engineer can usually design a solution to strengthen the roof and ensure compliance with guarantees and safety standards.
• Optimise your plans in collaboration with solar installers: There are many types of solar panels for commercial use so time researching and discussing your options with various installers will prove to be time well spent.
• Check your insurance and liability: Make sure you’re covered against potential structural or electrical issues related to solar power for warehouse systems.

Seize the Solar Opportunity

All things considered, warehouse roofs offer a strong environmental and financial opportunity for businesses and it’s easy to understand the rising interest in solar panel installations in London and across the UK. The potential to achieve significant energy savings and a reliable solar energy return on investment is clear and worth exploring.
