Solar Panels for Offices & Warehouses in Cardiff

Offices and warehouses are ideal candidates for solar energy. With large, flat or low-pitch roofs, consistent daytime energy usage and high electricity bills, commercial premises in Cardiff can achieve some of the best returns on solar investment of any property type.

GL Solar has installed solar systems on offices, warehouses, retail units and commercial premises across Cardiff and South Wales. Our commercial team understands the unique requirements of business installations — from minimising disruption to your operations to managing planning applications and DNO connections.

Whether you own or lease your premises, we can advise on the best approach. Many Cardiff businesses are now installing solar under Power Purchase Agreements (PPAs) — meaning zero upfront cost and immediate savings from day one.

We also install solar for co-working spaces, serviced offices, call centres and light industrial units across Cardiff. These businesses typically have predictable daytime electricity profiles that align perfectly with solar generation, making them excellent candidates for high self-consumption rates and strong ROI.
