Energy for your business
Make more of your roof space.
Solar designed around your working day.
- Site feasibility
- Daytime energy use
- Grid connection
Commercial solar PV generates electricity at your premises. The most useful first comparison is between generation through the day and the electricity your business uses at those times. Annual bills alone can hide weekend closures, seasonal demand or a shift pattern that changes how much solar you can use.
For a warehouse, office, workshop or retail unit, gather interval consumption data where available, the supply details, roof information and your lease or ownership position. Ask an installer to model on-site consumption and export separately, and to state any assumed changes in energy prices.
Grays Solar handles commercial enquiries for the Grays and Thurrock area. Partner installers can get a next appointment booked within 24 hours of receiving an enquiry. Feasibility, grid approval, installation planning and contracting are handled by the installer you choose.
The details that shape your system.
Demand and operating hours
Provide half-hourly electricity data if available, including weekends and seasonal changes. Ask whether the proposed system is sized for current loads or planned expansion.
Roof and structural checks
Confirm roof condition, loading, access and any material risks before detailed design. Roof warranties and a planned refurbishment can affect the installation approach.
Lease and landlord consent
Establish who owns the roof and equipment and how long you expect to occupy the premises. Record any landlord, insurer or lender requirements.
Grid connection and export
Your installer should assess the UK Power Networks process, connection capacity and any export limits. Do not commit to export income before the connection position is understood.
Battery storage and fleet charging
Compare storage or workplace charging against actual load and vehicle schedules. Additional equipment needs its own business case and electrical assessment.
Operations and maintenance
Agree monitoring access, inspections, fault response, cleaning where needed and responsibility for downtime. Include maintenance and potential equipment replacement in the financial model.

Your Grays solar questions, answered.
How much does commercial solar cost?
A useful price needs a site-specific design. Roof condition, access, electrical infrastructure, system size and grid works can materially change the budget. Ask for capital cost, ongoing costs and VAT treatment to be stated separately.
What is the payback period?
There is no single payback period for Grays businesses. It depends on installed cost, self-consumption, import prices, export terms and operating costs. Ask for assumptions and sensitivity scenarios rather than a guaranteed number of years.
Can a tenant install solar?
This depends on the lease and the necessary consents. Establish roof rights, equipment ownership, maintenance access and what happens at the end of the lease with your advisers and landlord.
Do commercial roofs follow domestic planning rules?
Do not assume they do. Have the installer and planning adviser check the rules that apply to the premises and proposed equipment. Thurrock Council is the local planning authority.
Do you offer finance or power purchase agreements?
Grays Solar does not advertise a finance product. If an installer proposes finance or a power purchase agreement, compare the full term, total payments, ownership, exit conditions and responsibilities with appropriate advice.
