From overhead to asset: rethinking energy investment
While rising energy costs and the pressure to improve sustainability have led many businesses to consider renewable energy, concerns about capital expenditure have stifled investment. Mark Bramhall, Director of Commercial Strategy at Plug Me In, explains how a commercial solar installation is only the beginning and that, as an asset, the real financial gains come in the 25 years that follow.
Given that recent research from the British Chambers of Commerce shows 27% of UK businesses struggling to pay energy bills, it is little surprise that many are starting to rethink their approach to energy investment. However, while building services, facilities and energy managers increasingly view renewable energy solutions as strategic investments, there are still barriers to the long-term financial and environmental value they offer.
One significant obstacle is a mindset that focuses on capital investment rather than the returns generated over the system’s lifetime. Changing that approach starts with recognising renewable energy as a long-term asset rather than an upfront cost. While installation takes a matter of weeks, a commercial array will continue to deliver value for a quarter of a century.
This is why businesses should take a more strategic approach to energy management. Energy should be perceived as a strategic line item rather than another overhead to manage. Investment in renewable technologies, such as solar PV and battery storage systems, can simultaneously improve building performance, reduce operating expenditure and support wider organisational objectives.
Making investment more accessible
Though capital expenditure requirements can present challenges, businesses should not necessarily view this as a gatekeeper to investment. With funded models, leases and power purchase agreements available, they can buy the output without purchasing the equipment.
Financing models can help spread costs and accelerate adoption, making renewable technologies more accessible.
Alongside commercial finance options, government-backed initiatives, local authority programmes and sector-specific grants can all provide valuable financial support for qualifying projects. Although funding schemes frequently change, businesses that plan ahead are better positioned to take advantage of them.
Understanding payback and ROI
Return on investment (ROI) remains central to any capital expenditure decision. While payback periods vary depending on energy consumption, system size and available incentives, commercial solar installations can often achieve payback within five to seven years. The system, however, will continue to generate savings for decades afterwards.
Moreover, with integrated battery storage, energy usage can be optimised, strengthening the financial case for investment.
Importantly, payback calculations should not be limited to energy bill reductions. For businesses willing to take a long-term view, technologies such as solar PV, battery storage and intelligent energy management provide an opportunity to reduce operating costs, boost business resilience, strengthen environmental performance and support wider organisational objectives.
Planning ahead pays dividends
Businesses considering renewable energy investments should recognise that successful projects are built on careful planning long before installation commences. Design begins not with the roof but with the meter data: how the building uses power, hour by hour and season by season.
Getting the consumption profile right is crucial to ensure the right size array is installed, that a battery will earn its keep, and that an energy management system will add value. This is the point at which businesses can understand what the payback truly is.
Of course, there are other considerations. Commercial solar installations are rarely off-the-shelf solutions. Every building presents different opportunities and constraints, from roof suitability and structural factors to existing electrical infrastructure, operational requirements and future energy demands.
Maximising long-term gains
While solar panels might look fine from the car park, minor faults or even soiling can reduce their output for months without being noticed, decreasing the financial returns. Monitoring, maintenance, ongoing management and technical support are therefore essential to maximising system performance and ROI.
From a strategic perspective, these are not optional extras, but the difference between owning a long-term asset and owning a rumour of one. To make the greatest gains, businesses should view installation as the start of the project, not the end. The real value comes from ensuring the system performs optimally year after year.
One way of achieving this is to integrate renewable technologies into a wider strategy that encompasses building controls, monitoring systems, maintenance planning and operational performance. This approach changes it from being a means of reducing electricity bills to becoming part of critical building infrastructure.
For businesses, renewable technology means energy is no longer an overhead to be tolerated, but an asset to be run – and optimising performance is crucial to maximising ROI.
The technology is proven, the commercial case is solid, and firms that invest today will be better positioned for the challenges and opportunities of tomorrow.
Working with an end-to-end partner capable of supporting the entire project lifecycle can help alleviate the challenges, ensuring businesses select the most appropriate technologies to maximise performance, carbon reduction and financial return. They can also help businesses navigate funding and financing options.
