How Much is the Average Cost of Industrial Solar Panels in the UK?
In the UK, the average cost of industrial solar panels typically ranges from £600 to £1,000 per kWp installed. Industrial systems range from somewhere around £45,000 for a 50 kW setup to £400,000 for a 500 kW system. However, the cost varies depending on several factors such as system size, roof complexity and specific requirements.
| System Size | Estimated Installation Cost | Typical Use Case | Estimated Payback Period |
| 50 kW | £45,000 to £50,000 | Small warehouse or commercial unit | 3 to 5 years |
| 100 kW | £75,000 to £100,000 | Medium sized factory or logistics building | 3 to 5 years |
| 250 kW | £175,000 to £212,500 | Large warehouse or distribution centre | 3 to 5 years |
| 500 kW | £350,000 to £400,000 | Large industrial facility or manufacturing plant | 3 to 5 years |
What Affects the Cost of Industrial Solar Systems?
When just looking at average price ranges for an industrial solar project, they do provide some helpful guidelines. However, there are actually several components that can affect the cost of an industrial solar project.
- System Size
The solar system size is an important driver of overall cost; larger systems generally will cost less as they create lower kWh prices. Large industrial facilities will benefit from this by having a lower cost per kWh than smaller facilities because of their larger size.
- Roof Type and Structural Strength
The roof type (and condition) will generally affect the cost of the installation.
- Metal roofs tend to allow for a lower cost of solar installations
- Flat roofs may require special mounting design systems
- Older roofs may need to have structural reinforcement before installation.
- Solar Panel Efficiency
Higher efficiency solar panels typically cost more, but higher efficiency solar panels create greater amounts of energy (kWh) per square meter, thus allowing for improved overall performance of the system.
- Installation Complexity
There are many factors including but not limited to roof access, scaffolding requirements, electrical upgrades and other safety related costs, that could alter the cost of the installation.
- Battery Storage
Some organisations choose to install battery storage systems so that they can store excess solar energy for later use. While this increases the organisation’s total project costs, the addition of battery storage can improve the organisation’s overall energy independence and operational efficiency.
- Quality of the equipment installed
High efficiency modules (like monocrystalline or bifacial) can cost more than standard panels.
Industrial Solar Installation Costs Per kWp in the UK
Another way to gain insight into solar pricing is by breaking down the figures into kilowatt-peak (kWp). Average prices in the UK by type of business include:
- Small Commercial Solar Installations: Average price range – £900 to £1,000 per kWp
- Medium Industrial Solar Installations: Average Price Range – £700 to £900 per kWp
- Large-Scale Solar Installations: Average Price Range – £600 to £750 per kWp
Thus, larger industrial installations typically enjoy the benefit of economies of scale. Hence, the cost per unit of solar capacity becomes more affordable when compared with smaller projects.
How Much Money Can Businesses Save with Industrial Solar?
There are several long-term benefits associated with being able to produce electricity using industrial solar systems. Most notably, businesses can easily realise tremendous cost savings.
For example, a 100 kWp solar system can produce anywhere between 85,000 and 95,000 kWh of usable electricity annually. Based on current energy prices, the average business could expect to see annual savings of approximately:
- For Small Commercial (100 kWp) Installations – £20,000 to £30,000 annually
An even greater amount of money can be saved by companies requiring a total amount of energy to produce their products that exceeds 100 kWp.
Return on Investment Example
Following is an example of what a typical return on investment (ROI) calculation looks like for a business investing in industrial solar:
- The Total Size of the Solar System Installed at Time of Purchase: 100 kWp
- Total Cost of Solar System: £90,000 (average for this example)
- Annual Amount Saved (electricity generated/usable): £22,000
- Expected Timeframe Before Achieving ROI: 4 to 6 years
What are the Government Incentives and Financial Support in the UK?
Smart Export Guarantee (SEG) – This incentive allows you to sell any surplus electricity that you have produced back to the grid so that you can generate a source of additional income from your unused solar energy.
Capital Allowances – This provides tax relief to all businesses in the UK for capital investments that are made in renewable energy. The amount that you can claim for capital allowances will be deducted from your taxable profit.
Industrial Solar ROI – What UK Businesses Can Expect
Research has shown that industrial solar systems are an excellent long-term investment with significant profit potential. The following have been identified as the primary financial advantages of investing in an industrial solar system:
- Return on Investment (ROI) is typically between 15 to 25%
- The standard payback period is approximately 4 to 7 years
- Typical life span of a system is between 25 and 30 years
- Lower Risk exposure to fluctuations in the price of energy

FAQs About How Much Do Industrial Solar Panels Cost
Question. How much do industrial solar panels cost in the UK?
Answer. The average cost of industrial solar panels in the UK typically ranges from somewhere around £600 to £1,000 per kWp installed.
For Example –
- A 100 kWp system may cost around £75,000 to £110,000

However, cost may vary depending on the roof type, equipment quality and installation complexity.
Question. What factors affect the cost of industrial solar panel installations?
Answer. Several factors affect the cost of an industrial solar project which include the following:
- System size
- Roof type and structural condition
- Panel efficiency
- Installation complexity
- Battery storage systems
Question. How long do industrial solar panels last?
Answer. An industrial solar panel will last around 25 to 30 years before being replaced. However, they will still have some ability to produce electric energy after that time, but they will not perform as efficiently as compared to the time just after installation.
Question. How much money do businesses save on their utility bill with industrial solar panels?
Answer. Utility bills for businesses installing an industrial solar system can typically be reduced by 30% to 70% of the total cost per kWh, depending on the size of the system and the way it uses energy. For example, a 100 kW solar system could save a business between £20,000 and £30,000 in utility payments on an annual basis, based on current electricity prices in the UK.
Question. How much roof space is required for an industrial solar system to be installed?
Answer. You will need to allocate 4 to 5 square meters per kW for your overall solar capacity. Therefore, for example, if your overall solar capacity is 100 kW, you will need 400 to 500 square meters of roof space for the installation of your industrial solar system.
