Commercial Solar Panels

Solar panels, also known as photovoltaics (PV), capture the sun’s energy and convert it into electricity that you can use in your commercial residents.​ By installing solar panels, you can generate your own renewable electricity.

What our customers say


The benefits of commercial solar


Cost savings

Solar panels generate free, green electricity during daytime hours, lowering your business demand for energy from the grid and potentially saving thousands of pounds on energy bills.


Solar income

Ideally, you would use all the solar power onsite, however any surplus power can be sold to the grid.


Financial stability

With energy prices predicted to sharply rise in the next 10 years, commercial solar panels allow you to effectively forward buy your electricity at a set price, making financial forecasting much easier.


Lower carbon footprint

Generating your own solar energy will significantly reduce your carbon footprint, increase your company’s sustainable credentials and improve your business reputation.


Low risk investment

Solar PV is a reliable and safe investment vehicle that provides returns exceeding those of traditional low risk financial products.


Energy security

With the grid and district network operators struggling to meet the UK’s growing energy demands, and the government’s recent introduction of mandatory energy audits for large businesses via the Energy Savings Opportunity Scheme (ESOS) and the possibility of further energy usage regulation, independent solar installations are an excellent backup measure.

There are significant benefits to be had from investing in solar energy, for businesses large and small. With rising energy costs, putting your roof space to good use is always beneficial. Many commercial organisations have already realised the huge potential savings available from solar energy. Simply by utilising the roof space on your commercial premises, agricultural buildings, factories, warehouses, schools or hospitals, you can install solar power generators and start generating free solar energy.

How long does solar panel installation take for a house?

Every commercial solar PV project is different and the cost of an installation can vary. Variables include the size of the system, where the panels are going to be placed, installation requirements (scaffolding, access, electrical equipment etc) quality of products (including warranty length) and labour…to name just a few. When you first contact us about a solar project we’ll briefly discuss these variables with you and provide an indicative estimate for you to consider. If you’re happy with this estimate, we’ll then carry out a site survey following which we’ll provide a formal proposal.
