Stewart Golf Ltd

Stewart Golf hits the green with solar investment

Stewart Golf is a British designer and manufacturer of the world's finest powered golf trolleys and accessories. Founded more than 15 years ago, Stewart Golf's headquarters is a 10,000sq ft facility in Gloucester. Reducing their environmental impact was a major driver for forward thinking Stewart Golf. Their investment in solar PV will make them significantly more energy efficient, keep their manufacturing costs as low as possible and reduce their carbon footprint.

Mypower designed and installed a 49.84kWp solar PV system that will meet nearly two thirds of Stewart Golf's annual energy consumption needs. The 178 panels fitted to the roof of the Stewart Golf factory delivers 46,000kWh of electricity a year and saves 15 tonnes of carbon emissions.

Future proofing

Stewart Golf went 'large' with their system. What we mean by this is that their goal was to maximise their long-term benefit and reduce their dependence on grid supplied electricity, rather than targeting the shortest payback period. The installed 49.84kWp system will supply 60% of their annual electricity requirements with clean, low cost electricity. With only 40% of the PV system's generation expected to be used on-site, 60% is being exported/sold to the grid at c.5p/unit. However, this provides opportunity for the future. 

Electricity consumption is likely to rise in the coming months and years, driven primarily by the impending Electric Vehicle (EV) revolution (and we're not talking about Stewart Golf's market leading golf trolleys). EVs will increase Stewart Golf's electricity consumption, in turn using more of the solar energy and reducing the system payback period under the commercial principle of less solar electricity exported and sold to the grid at c.5p/unit, and more used on-site to displace expensive grid supplied electricity costing c.15p/unit.

Another future factor considered was battery technology. The cost of battery storage continues to reduce, and grid supplied energy prices continue to rise, so it won't be too long before battery storage makes great commercial sense for the excess renewable energy to be stored on-site. When this time comes, Stewart Golf will increase their already impressive stat of providing over 60% of their electricity needs with their own solar PV system, and step much closer to their ultimate goal of being completely self-sufficient on their own, locally produced renewable energy.

Mark Stewart, CEO at Stewart Golf...

"We're very proud that our new PV system will be generating clean electricity for our business for many years to come. Not only is it a great green decision, it's also a very sensible financial one so really is a win-win for us."

"Mypower made everything very straightforward. Their knowledge and advice about commercial solar PV gave us a huge amount of confidence to take our aspirations to 'go Solar' into reality and it was a easy decision to go with Mypower." 

"Owning our own building means we can make long term investment decisions. Going solar self-sufficient reduces our carbon footprint and helps generate green power to go back into the grid to supply other businesses and homes with solar energy."

Key facts and predictions with no subsidy or grants

  • 49.84 kW (179 Panels) installed by Mypower.
  • 46,905 kWh units of energy produced per annum.
  • £4,287 - Projected first year income and savings assuming 40% of electricity used on site.
  • 12.1% projected first year return on capital invested, before capital allowance benefits.
  • 4.66 p/kwh - equivalent forward purchase price of 1,080,203 units of electricity over 25 years including estimated O&M costs, and excluding potential Annual Investment Allowance tax benefit.
  • 15.5 tonnes of CO2 emissions avoided per annum.
  • 8.3 years system payback before finance, tax and capital allowance benefits
  • £211,230 - Total projected income and savings over 25 years after indexation.
  • 69% saving from solar PV electricity compared to grid supplied electricity at 15.35 p/kWh.
  • In the first 10 full months of operation, the system has produced 44,787kWh, which is 95% of the total annual production predicted in Mypower's initial quote. With 2 months to go, albeit winter months, the system is on track to match, if not over perform, against our annual generation projections.
