Future-proof your energy bills & avoid power disruption

With the world moving away from fossil fuels and towards more sustainable forms of energy, it is no surprise that there is more demand for commercial solar PV now than ever before. The sharp increase in business energy bills, unpredictability in the global economy, and the fact that customers are now leaning towards green-focus companies who strive for ‘net zero‘, means now is the time to start thinking of investing in a greener future. Another way your business can benefit from commercial solar PV is through meeting your ESG (Environmental, Social & Corporate Governance) obligations. As one of the most trusted commercial solar panel installation companies in the UK, we have worked with many businesses in manufacturing, education, leisure, engineering, agriculture and finance, to help them go green and produce their own sustainable energy.

Financing Commercial Solar PV Systems

Installing a commercial solar PV system is an investment that will pay for itself over time but the initial outlay can be a daunting prospect.

Fortunately, there are three flexible ways you can approach commercial solar financing for green energy systems:

A Power Purchase Agreement (PPA)

PPA means that your business solar PV system is fully paid for and maintained by the finance company. Your company would agree to rent your roof space for the duration of the contract to the finance company and to purchase the energy generated by the system. The energy generated will cost 20% less than you would pay from the grid for the same amount of energy. At the end of the PPA term, the system is gifted to your company for continued use.

A lease scheme

A lease is a loan secured on the equipment being purchased. The equipment remains the property of the lease company until the end of the agreement, at which point it is signed over to you for a peppercorn payment. Leasing is tax efficient and will enable you to remain cash flow positive on the system generation

Buying your commercial solar panels outright

While this is the most expensive option upfront, you generally get the quickest return on investment because there is no extra finance to be paid.

What is ESG and why do you need to get on board?

ESG is a framework that businesses are now using to measure their performance in terms of sustainability. Environmental, Social and Governance factors are taken into consideration when making vital business decisions and creating internal processes. These activities include lowering pollution and waste, as well as establishing a more diverse and inclusive workforce. The main objective of ESG is to help businesses to create a more positive impact on society and the environment.

Commercial Solar Installation FAQs

What is the return on investment on commercial solar panels?

Depending on the size of solar PV system you are installing, a typical payback would be between 3 and 7 years. Current grid energy costs and site usage also play a factor in this. We would provide a full financial analysis as part of our design pack, looking at historical half hourly data.

What solar panel is best for commercial use?

Some of the most popular and reputable solar panel manufacturers for commercial use are Canadian Solar, Trina Solar, Jinko Solar, Hanwha Q CELLS, REC, Longi. SunPower also offer a commercial panel with industry leading warranties. We work with and install some of the best brands out there, so if you have any specific questions, please feel free to get in touch with our expert team of commercial solar panel installers.

How much electricity can a commercial solar panel generate?

The commercial solar panels TLGEC install are between 400-500W peak energy per panel and are most beneficially orientated facing south at 30 degrees pitch in direct sunlight, but the cells do not need direct irradiance to work and can still generate power on cloudy days. It is also popular to install an East-West system on larger buildings that are typically low pitch. Many businesses will also install a commercial battery storage system to optimise the site self-consumption of the generated energy.

What are the most efficient commercial solar panels in the UK/World?

The most efficient commercial solar panels in the UK/World are the SunPower Maxeon panels at 22.7%. We work closely with our clients to ensure that the commercial solar panels we install for them match their energy efficiency requirements.

Do I need planning permission for solar panels on a commercial building?

You will not typically need planning permission to install solar panels on a commercial building as they are considered permitted development, but they do need to be installed a minimum of 1000mm from the edge of the roof and must project higher than 200mm from the roof surface. If the system is greater in size than 1 Megawatt planning permission will be required.

How many solar panels are required on an office building?

There is no set amount, it depends on how much energy the site consumes and budget. We would discuss the requirements and objectives with you and design a system to suit.

Can I claim solar panels as a business expense?

You can claim a Capital Allowance on any solar panels you want to have installed on your commercial property. Capital allowances on solar panels are tax deductions that businesses can claim on the cost of installing solar panels in commercial properties.

Do I need a license for commercial solar panels in the UK?

There is no permit required for commercial solar installation in the UK. As solar panels are considered ‘permitted development’ you usually don’t need planning permission to install them on your roof. A grid application would be required to connect to the grid. This would all be part of our design package.

How efficient are commercial grade solar panels?

The commercial solar PV modules we install are 20-22% efficient which has now effectively reached the commercially available upper limit for silicon cells. The theoretical maximum for silicon is 29%. To go beyond this new materials are being tested in laboratories in conjunction with silicon, such as perovskite. These are still years away from becoming commercially viable.

Does solar help with ESG objectives?

Yes, solar panels so have a positive impact on improving the ESG score of your business. Solar can help companies meet both environmental and social goals, providing green energy and elevating a company’s standing with its stakeholders.

What size are commercial PV panels?

Commercial solar panels are typically between 1808-2135mm long by 1086-1092mm wide Commercial solar panels tend to be larger in size compared to residential solar panels.

How long do industrial-grade solar panels last?

As commercial solar PV installers, it is our job to provide our customers with the most reliable solar solution available. That is why we only work with the leading technology providers in the PV space. The commercial solar panels we supply come with a 25-year performance warranty – to be at least 80% efficient after 25 years.

Do commercial solar panels require servicing?

Solar panels are designed to be low maintenance. However, we would advise having your system checked over annually to ensure your investment is operating to its full potential. We would also advise an annual/bi-annual cleaning to ensure the highest generation possible.

What is the difference between domestic and commercial solar panels?

There is no difference between commercial and domestic PV (photovoltaic) panels. They’re both made from a collection of silicon semi-conductors which convert sunlight into electricity. Each individual panel is just one part of your solar installation (or array of panels). The only notable difference may be the size of the panels, as commercial solar panels tend to be larger than residential panels. Residential panels also tend to be black framed with black backing sheets, this is purely for atheistic reasons as generally they are more visible.
