Commercial Solar Panel Installations

The cost of a commercial solar panel installation depends on the size of the system, your business's energy usage, roof space, equipment specification and installation requirements. Larger commercial systems typically require a higher initial investment but can also deliver greater long-term energy savings.

ProStar Energy can assess your site and energy consumption to recommend a system that suits your business and provide a tailored quotation.

The payback period for commercial solar panels varies depending on the cost of the installation, how much electricity your business uses, current energy prices and how much solar energy you can use on site.

Businesses with high daytime electricity consumption can often achieve particularly strong returns because more of the electricity generated by the system is used directly rather than purchased from the grid. ProStar Energy can provide an estimated payback period as part of your commercial solar proposal.

Many commercial solar panel installations can be completed under permitted development rights, meaning a full planning application may not be required. However, restrictions can apply depending on the building, system size, location and whether the property is listed or within a protected area.

ProStar Energy can review your site and advise whether planning permission is likely to be required before installation begins.

Many commercial solar installations require approval from the local Distribution Network Operator (DNO), particularly larger systems that export electricity back to the grid.

The requirements depend on the size and specification of the solar installation and the capacity of the local electricity network. ProStar Energy can help manage the relevant DNO application process as part of your commercial solar project.

The number of solar panels your business needs will depend on your electricity consumption, available roof or ground space, when you use electricity and your objectives for the system.

Rather than simply installing as many panels as possible, a commercial solar system should be designed around your business's energy profile to maximise the amount of solar electricity you can use on site.

There are a number of ways businesses may be able to fund commercial solar installations, depending on their circumstances and the options available at the time.

ProStar Energy can discuss the available routes with you and help you understand the potential costs, savings and return on investment before you make a decision.

Yes. Warehouses can be particularly well suited to commercial solar because they often have large areas of unused roof space and significant daytime electricity consumption.

Before installation, the roof will need to be assessed for factors including available space, orientation, shading and structural suitability. ProStar Energy can carry out a site assessment to determine whether your warehouse is suitable for solar panels.

For many businesses, commercial solar can significantly reduce reliance on electricity purchased from the grid and provide greater control over long-term energy costs.

The financial benefits depend on your electricity usage, site conditions and system design. A commercial solar assessment can help determine the potential savings and return on investment for your individual business.

Potential savings vary considerably between businesses. Companies that consume a large amount of electricity during daylight hours will generally be able to use a greater proportion of the solar electricity they generate.

ProStar Energy can analyse your electricity usage and provide an estimate of the potential generation, savings and payback period for a proposed system.

If your solar panels generate more electricity than your business is using, the surplus electricity can potentially be exported to the National Grid.

Depending on your system and energy arrangements, your business may be able to receive payment for eligible exported electricity. Alternatively, battery storage can help you retain more of the electricity generated on site.

Yes. Commercial solar panels can be installed alongside battery storage, allowing your business to store surplus solar electricity and use it later.

Battery storage can be particularly useful for businesses with electricity demand outside peak solar-generating hours. Whether battery storage is financially suitable will depend on your individual energy profile.

Yes. Generating renewable electricity on site can reduce the amount of electricity your business needs to purchase from the grid and help lower its operational carbon emissions.

Commercial solar can therefore support wider sustainability, ESG and carbon-reduction objectives while potentially reducing energy costs.

Modern solar panels are designed for long-term operation and will typically continue generating electricity for several decades, although their output gradually reduces over time.

The equipment warranties available will depend on the panels, inverters and other components selected for your installation.

Commercial solar installations can usually be planned to minimise disruption to normal business operations.

The exact installation programme will depend on the size and complexity of the project. ProStar Energy can discuss access, working hours and operational requirements with you before work starts.

Suitability depends on factors including available roof or ground space, orientation, shading, roof condition, structural capacity and your electricity consumption.

A professional site survey is the most reliable way to understand what size system could be installed and whether commercial solar is likely to provide a strong return for your business.

Yes. Solar panels can be installed on many flat commercial roofs using mounting systems designed to position the panels at an appropriate angle.

The roof's condition, loading capacity, available space and drainage requirements will need to be considered when designing the system.

Yes. Where suitable land is available, businesses can consider a ground-mounted solar installation instead of, or alongside, rooftop solar.

Ground-mounted systems can be useful for farms, estates, industrial sites and businesses with limited suitable roof space, although planning and grid requirements will need to be considered.

A great alternative to this would be to install solar canopies over carparks or over land already in use.

Installation times depend on the size and complexity of the system, roof access, electrical works and any planning or grid-connection requirements.

Once the necessary surveys, approvals and design work have been completed, ProStar Energy can provide a clear installation programme for your project.

The best starting point is an assessment of your property and recent electricity usage. This allows the proposed solar system to be designed around how your business actually consumes electricity.
