Commercial Solar for Every Type of Business

What’s Included in a Commercial Solar Installation
Every commercial project starts with a free, no-obligation site survey to assess your roof or ground space, current electricity usage and daytime demand profile. From there we handle: system design sized to offset as much of your daytime demand as possible; roof or ground-mounted installation (flat, pitched or ground-mount for larger sites); grid connection and DNO notification handled on your behalf; real-time monitoring via our app monitoring platform; and MCS certification, required for Smart Export Guarantee eligibility and grant compliance.
Commercial Solar Payback, Tax Relief and Export Income
Commercial solar PV typically pays back within 4–7 years, depending on system size, your daytime energy usage and current electricity tariff. Businesses may also benefit from capital allowances (speak to your accountant to confirm current eligibility), Smart Export Guarantee income for excess exported electricity, and 0% VAT on many commercial installations — we confirm eligibility during your free survey. Figures are illustrative only; we provide a tailored payback estimate as part of every commercial quotation.

- A Solar PV system will generate your business FREE electricity during day light hours.
- The capital cost is a 100% Tax Deductible business expense.
- The business will automatically use the Solar panel produced electricity before any is imported through the properties electricity meter.
Example 1
The business premises requires 11 kW of electricity to satisfy the electrical demand at a certain time. The Solar PV system is providing an output of 9 kW at this particular time.
In this scenario, the business will only pay for the 2 kW of electricity that the solar panels system is not providing.
When conditions are such that the business’ electrical demand is being fully satisfied by the solar panel system, excess produced electricity is automatically exported to the Nation Grid.
The owner of the Solar panel system will be paid for this TAX FREE via SEG payments.
Example 2
The business premises requires 8 kW of electricity to satisfy the electrical demand at a certain time. The Solar PV system is providing an output of 12 kW at this particular time.
In this scenario, the business will be running purely on the Solar panel electricity and there is 4 kW of electricity that is surplus.
The surplus generated electricity will automatically flow into the National Grid via the electricity meter. This is known as Exported Electricity.
The smart meter will know that this is exported electricity and the amount exported is recorded in kW hours. Exactly the same way as purchased electricity is recorded.
The good news
You are now paid for Exported electricity - TAX FREE
Exported electricity is paid for via a government backed scheme called SEG (Smart Export Guarantee)
You are guaranteed to be paid and at generous rates. This will continue to be the case for decades to come. At present (2025) export payments are paid for at a general rate of 15 Pence / kWh.
The reason the UK Government is paying SEG Payments is because every single kW hour of electricity that is fed into the National Grid from Solar panel systems, its a kW hour of electricity that a power station does NOT have to produce.
This very simple operation is driving down the UK’s reliance on fossil fuel burning power stations and helping to reduce the environmentally harmful carbon emissions.
It also removes a percentage of the cost of expensive maintenance and up keep on the power stations so its better for them to pay us SEG payments and keep bigger outlays low.
The SEG payments used to be 8 Pence / kWh. In 2022 they rose to 12 P / kWh and now they are at 15 P / kWh. They are estimated to rise again soon to 18 P / kWh to encourage more Solar PV systems on the network.
