The big switch on: solar panels fully operational at Diamond

Recently installed solar panels that cover the entire roof of Diamond Light Source are now fully operational.  Diamond’s roof covers an area of 32,000m2  which offers an exceptional opportunity to maximise energy efficiency through these panels. 

The energy generated by the solar panels is an annual supply of 2.3GWh/y​. This output amounts to around 5% of the facility’s total annual energy consumption and will mean yearly savings of some half a million pounds. This will additionally contribute to energy savings of more than £2M per year. 

The installation was part of a larger roof maintenance project which presented the opportunity to install a 2.7MW solar panel array.  

Since Diamond’s construction in 2005, the organisation has enhanced the efficiency of existing equipment and limited the amount of equipment needed to run without affecting machine operation. These steps are central to Diamond’s prioritisation of sustainability in all areas of the construction and operation of the facility. Areas of focus have been waste reduction, use of low-carbon electricity supply where possible and the introduction of photovoltaic panels. 

The facility has also made additional significant advances in energy efficiency, with implementations ranging from motion sensors on lighting and LED-based light bulbs to variable speed drives on pumping equipment. These initiatives have achieved ongoing electricity savings of over £2 million a year.  

Diamond fully endorses the Government’s ambition to achieving net zero emissions by 2050, which is aligned with the Paris Agreement, to address climate change effectively.  

As well as operating in a sustainable way, Diamond’s scientists and users greatly contribute to global research and technological development in energy efficiency.
