How do solar panels work? +
Solar panels work by converting sunlight into electricity using photovoltaic (PV) cells. These cells capture solar energy and create an electrical charge that can be used to power your property. Some large-scale systems use Concentrating Solar Power (CSP), which uses mirrors to focus sunlight and generate heat that is then converted into electricity. CSP is typically used for very large commercial applications.
How long will it take to install solar panels on my commercial property? +
The installation timeline varies depending on the size and complexity of your property. Approval from the Distribution Network Operator (DNO) can take up to 12 weeks. Once approved, most commercial installations take between two and six weeks to complete. Larger rooftop portfolios or multi-site projects may take longer due to structural surveys, grid applications and phased rollouts.
Can my building operate as normal during installation? +
Yes. There is usually minimal disruption to day-to-day operations. Our trusted partners work around your schedule to minimise downtime. Most electrical tie-ins are completed outside of business hours or during planned maintenance windows to avoid any disruption for tenants or customers.
What is the lifespan of a commercial solar PV system? +
A commercial solar PV system can last 25–40 years. Most manufacturers offer panel performance warranties of at least 25 years. Routine cleaning and annual servicing help maintain system efficiency and ensure ongoing performance for decades.
Can I install solar panels on a leased or multi-tenant building? +
Yes. Solar can be installed on leased or multi-tenant properties, provided you have written consent from the property owner or management company. Many landlords actively support solar installations because they can improve EPC ratings, attract tenants, and future-proof their assets.
How much do commercial solar panels cost? +
Costs depend on the size of your system, roof type, and energy consumption profile. As a guide, commercial installations typically range between £700 and £1,000 per kWp. A 100 kW system may cost around £70,000–£100,000, and a 250 kW system could range from £200,000–£250,000. Despite the upfront investment, solar delivers strong long-term returns through lower electricity costs and improved asset value.
Can solar panels improve my property’s EPC rating? +
Yes. Solar PV can significantly improve your Energy Performance Certificate (EPC) rating by reducing grid electricity use and carbon emissions. Many landlords use solar upgrades as part of wider sustainability improvements to meet Minimum Energy Efficiency Standards (MEES).
What are the financial benefits of solar for landlords? +
Installing solar can increase property value, attract sustainability-focused tenants, and reduce void periods. Landlords can generate additional income through on-site power purchase agreements (PPAs) or export tariffs under the Smart Export Guarantee (SEG). Solar also demonstrates ESG leadership, which appeals to investors and occupiers alike.
Do solar panels work for mixed-use or multi-storey properties? +
Yes. Commercial installers can design bespoke systems for office blocks, retail units, industrial estates or mixed-use buildings. Energy metering and distribution can be tailored to individual tenants or common areas, ensuring fair allocation of generation and usage across the property.
Are there finance options available for commercial property owners? +
Yes. You can choose from CAPEX (direct purchase), OPEX (leased), or Power Purchase Agreement (PPA) models. PPAs allow you to benefit from lower energy costs without paying upfront, while the installer retains ownership and maintenance responsibilities. Each route has different accounting and tax advantages, so it’s best to review them side by side before committing.
Do solar panels require planning permission for commercial buildings? +
In most cases, rooftop solar installations are classed as permitted development and do not require full planning permission. Exceptions include listed buildings, conservation areas, or systems that exceed certain height or visibility limits. Your installer will handle any required planning checks or local authority applications on your behalf.
How can solar panels support ESG and sustainability targets? +
Solar PV directly reduces Scope 2 carbon emissions and supports corporate net-zero strategies. For property investment portfolios, on-site generation also improves ESG ratings, enhances green credentials, and increases asset resilience against rising energy costs. Many investors now consider solar an essential part of sustainable property management.
