Commercial solar — your questions answered
How much can commercial solar save my business?
Savings depend on roof size, energy usage profile, electricity tariffs and finance structure. The free calculator gives an indicative figure; a full proposal refines it.
Can commercial solar be cashflow-positive from day one?
On suitable sites, with the right energy usage profile and funding structure, commercial solar can be cashflow-positive from day one. This depends on site suitability and finance approval.
Do I need to pay upfront?
Not necessarily. Asset finance, PPAs and lease structures may spread or remove upfront cost, subject to lender approval.
Can I sell electricity back to the grid?
In most cases, yes — surplus export is paid for under an export tariff. Export capacity is subject to your DNO connection conditions.
Is my roof suitable for solar panels?
Most large commercial roofs can host solar, but structural, surface condition, age and access all matter. A roof assessment confirms suitability.
Do I need planning permission?
Many commercial solar installations fall under permitted development, but planning may be required depending on location, listing status and scale. We review this case by case.
What is a DNO application?
A formal application to your Distribution Network Operator to connect the system to the grid and confirm export limits.
What is G99?
G99 is the engineering standard governing how generation systems above small thresholds connect to the UK distribution network.
What happens if export is limited?
An export limit caps how much you can send back to the grid. Systems can still be sized effectively for self-consumption, sometimes with export limitation devices.
Can I install solar if I lease my building?
Often yes — but the landlord must agree, and the commercial structure (who owns the system, who benefits) needs care. We help map the right arrangement.
How long does installation take?
Typical commercial installs run from several weeks to a few months, depending on system size, roof complexity and grid connection timelines.
Will installation disrupt my business?
Roof works are sequenced around operations and electrical tie-ins are scheduled at agreed windows to minimise disruption.
What warranties are included?
Panel performance and product warranties, inverter warranties and installer workmanship warranties — confirmed in your proposal.
What happens if I move premises?
Options depend on ownership and finance structure. Some systems can transfer or be repurchased; we explore the right path during proposal.
Can I claim tax relief?
Commercial solar may qualify for capital allowances — confirm with your accountant or tax adviser based on your specific business and finance structure.
Is VAT charged on commercial solar?
Yes, commercial solar installations are typically subject to VAT at the standard rate, unlike some domestic installs.
Do I need battery storage?
Not always. Batteries can improve self-consumption and resilience but add cost. Many businesses install solar first and add storage later.
What information do you need from me?
Typically: recent energy bills, postcode, roof information (or photos / drawings), ownership status and an idea of your funding preference.
