In July 2018, Spirit Solar installed an 11.7kWp solar PV system at the Premier Inn Salisbury. The PV array consisted of 45 x Perlight 260W PV panels mounted on a flat roof with an incline of 30 degrees. It is expected that approximately 80% of the power generated by the PV will be used on site. The annual power output is projected to be in excess of 11,000kWh, with the savings and tariff income amounting to £1,735 per year for the next 20 years.
