Commercial solar panels UK
Commercial solar designed around your energy demand.
3Phase helps UK businesses reduce long-term electricity costs with commercial solar solutions designed around energy usage, roof suitability, tariff exposure and future infrastructure plans.
Commercial Solar Calculator
Calculate Your Potential Savings
Use your annual electricity spend, sector and postcode to create an indicative commercial solar estimate. The figures are a starting point only, but they help frame whether a detailed solar assessment is worth reviewing.
Your Potential Savings
Indicative commercial solar estimate based on typical consumption patterns.
Estimated Annual Savings£0per year

Carbon Reduction0tonnes CO2e per year
Results are indicative and based on typical commercial consumption patterns, sector load profiles and regional generation assumptions. A full 3Phase assessment reviews half-hourly data, roof condition, grid position and operational use to produce accurate figures.
Evidence-led design
A proper solar proposal starts with the business case, not the panel count.
Commercial solar for businesses should be modelled against how electricity is actually used on site. A strong proposal considers annual consumption, half-hourly energy data, operating hours, roof condition, grid connection, funding preference and whether future EV charging or battery storage will change demand.
For suitable sites, solar panels for businesses can create a long-term hedge against rising electricity prices by generating power where it is consumed. The aim is not simply to install the largest possible system. The aim is to design commercial solar panels around the financial case, the building and the operational needs of the business.

Commercial reasons
Why Businesses Invest In Commercial Solar
Reduce electricity costs
Generate electricity on site where the business can use it directly.
Improve energy resilience
Plan generation, storage and demand around the site’s operating needs.
Support EV charging
Prepare for workplace, fleet or visitor charging demand.
Improve ESG reporting
Support carbon reduction activity with a visible infrastructure plan.
Reduce price exposure
Create a long-term hedge against rising energy prices where the site is suitable.
Wider energy planning
Building Smarter Commercial Energy Infrastructure
Commercial solar is often the first step in a wider energy plan. For many UK businesses, the stronger long-term strategy brings rooftop generation together with commercial battery storage, workplace and fleet EV charging infrastructure.
Commercial Solar
Reduce imported electricity and create a long-term hedge against rising business energy costs.
Battery Storage
Support energy resilience and prepare sites for more flexible electricity use.
Commercial EV Charging
Plan commercial EV charging for staff, fleet, visitors and future site demand.
Business types
Commercial Solar For Different Business Types
The best commercial solar projects are matched to the way the site operates. 3Phase helps managing directors, finance directors, operations managers, facilities managers and commercial property owners understand whether solar, storage or charging infrastructure fits the business case.
Manufacturing
Reduce high daytime electricity demand with on-site solar generation.
Warehousing
Use large roof spaces to support lower-cost energy generation.
Logistics
Plan solar, storage and fleet charging around depot operations.
Agriculture
Support high-use rural sites with generation and resilience planning.
Retail
Lower operating costs across trading hours and multi-site estates.
Hospitality
Offset energy-intensive kitchens, accommodation and leisure facilities.
Education
Use campus roof space to support budgets and carbon reporting.
Care
Plan lower-cost electricity for care homes and high-use facilities.
Commercial Solar Case Study
46kWp solar installation at Billericay Town FC.
3Phase is delivering a 46kWp commercial solar PV system at New Lodge, home of Billericay Town FC. The project is PPA funded by HDM Energies and supports the club with lower-cost renewable electricity and reduced operational energy costs.

Commercial solar FAQs
Questions businesses usually ask before a proposal.
How much does commercial solar cost?
Cost depends on system size, roof condition, access, electrical works, grid requirements and funding route. A proper proposal should model the commercial case before price is treated as meaningful.
Can commercial solar work on a leased building?
Yes, but landlord consent, lease length, roof responsibility and access rights need to be reviewed before a commercial solar installation can move forward.
What funding options are available?
Common routes include capital purchase, asset finance and commercial solar PPA funding. The right option depends on cash flow, ownership preference and site suitability.
What is a Solar PPA?
A Solar PPA is a power purchase agreement where a funded system is installed on a suitable site and the business buys the solar electricity generated under an agreed contract.
Is it better to buy the system or use Solar PPA funding?
Capital purchase may suit businesses that want ownership, while solar PPA funding can suit businesses that want on-site solar without upfront capital. Both routes should be compared commercially.
Can battery storage be added later?
Often, yes. Battery storage should be considered during the design stage so future electrical capacity, space and operating requirements are not overlooked.
Can commercial solar support EV charging?
Yes. Commercial solar can support workplace, fleet and visitor EV charging when the expected charging demand is included in the wider site energy plan.
Can Tesla charging be integrated with solar?
Commercial EV charging can be planned alongside solar and battery storage where the site, grid capacity and operating profile support the business case.
How long does commercial solar installation take?
Timelines depend on system size, survey findings, permissions, grid work, access and operational constraints. Installation should be planned around business continuity.
Do commercial solar panels need maintenance?
Yes. Commercial solar panels require monitoring and periodic maintenance so faults, underperformance and site issues are identified early.
Does commercial solar require planning permission?
Some projects fall under permitted development, while others need planning review. Building type, location, system size and site constraints should be checked before installation.
How long do commercial solar panels last?
Commercial solar panels are commonly expected to operate for 25 years or more, with performance, warranties and maintenance considered as part of the proposal.
