Sainsbury's has installed 69,500 new photovoltaic solar panels, or 16 MW of power, across 169 stores in the UK. The significant investment means collectively Sainsbury's supermarkets currently host the largest solar array in the UK and Europe. The solar power will reduce Sainsbury's total CO2 emissions by an estimated 6,800 tonnes per year, and each store's energy consumption as well as delivering energy cost savings.
