How do solar panels work? +
Solar panels work by converting sunlight into electricity using photovoltaic (PV) cells. These cells absorb sunlight and generate electrical current through an internal electric field. Most commercial systems use PV technology, while larger-scale solar farms may use Concentrated Solar Power (CSP), which focuses sunlight to produce heat and then electricity. For retail and warehousing, PV is ideal—low maintenance, reliable, and scalable across multiple sites.
How long will it take to install solar panels at my retail business? +
Installation time depends on the size and complexity of your site. The Distribution Network Operator (DNO) approval process can take up to 12 weeks. Once approved, installation typically takes one to four weeks. Large retail parks or warehouse estates may take longer due to access, electrical integration, and roof area, but all projects are planned to minimise disruption.
Can my retail business operate while the solar panels are being installed? +
Yes. Your day-to-day operations can continue without interruption. Our MCS-certified commercial partners are experienced in working with retailers, supermarkets, and warehouses, and will plan around your trading hours. Any potentially noisy or disruptive works can be completed during off-peak hours, evenings, or weekends to avoid downtime.
What is the lifespan of a commercial Solar PV system? +
Commercial solar systems are extremely durable, typically lasting between 25–30 years, and can perform for up to 40 years with proper maintenance. Annual inspections, panel cleaning, and inverter servicing help ensure consistent generation. Most Tier 1 solar panels come with 25-year performance warranties, guaranteeing long-term reliability.
Can you install solar panels on a leased or rented commercial property? +
Yes, you can install solar PV systems on a leased or rented retail or warehouse property, provided you have your landlord’s written consent. Many UK landlords welcome solar installations because they enhance property value and sustainability credentials. Always confirm permissions before proceeding—our installer partners can support with the required documentation.
How much do commercial solar panels cost? +
Costs vary based on roof size, system design, and your power requirements. On average, commercial solar installation costs between £700 and £1,000 per kWp. For example, a 50kW system may cost around £40,000, while a 100kW system could range from £70,000–£100,000. Larger warehouse installations, such as 250kW systems, may cost £200,000–£250,000. Despite upfront costs, solar can reduce your energy bills by up to 60%, making it a sound long-term investment.
Can solar power support refrigeration and lighting in retail environments? +
Yes, solar PV is ideal for powering refrigeration units, lighting, and HVAC systems commonly used in retail and warehousing. Because these loads run mostly during the day—when solar generation is highest—your site can directly use the energy produced, significantly reducing grid consumption and operating costs.
Can I use solar panels across multiple retail or warehouse sites? +
Absolutely. Multi-site solar strategies are increasingly common for retailers and logistics operators. Our partners provide portfolio-based assessments that model potential generation and savings for each location, allowing you to compare ROI and rollout options across your estate. Larger groups often benefit from economies of scale and standardised PPA or lease agreements.
How can solar help my retail business meet ESG and sustainability goals? +
Solar energy helps retailers and warehouse operators directly cut Scope 2 emissions and demonstrate measurable sustainability action. On-site renewable generation supports ESG and CSR reporting, improves your green credentials with customers and investors, and contributes toward net zero targets under UK business carbon frameworks.
What is the typical payback period for a retail or warehouse solar system? +
Most commercial solar systems for retail and warehousing achieve payback within 4–7 years depending on energy usage, system size, and finance method. Businesses with high daytime energy demand see faster returns. After payback, the electricity generated is effectively free for the remainder of the system’s life, delivering decades of cost savings.
Can solar panels integrate with EV charging for retail sites? +
Yes. Solar PV can be integrated with on-site EV chargers to support electric delivery fleets or customer charging bays. Combined with battery storage, your business can use solar energy to charge vehicles during the day and store surplus energy for use overnight or during peak tariff periods.
Do I need planning permission for solar panels on my warehouse or retail site? +
Most rooftop commercial solar systems qualify as “permitted development” and do not require planning permission. Exceptions apply for listed buildings, conservation areas, or installations exceeding certain height restrictions. Your installer will confirm site eligibility and handle any required planning or DNO applications on your behalf.
