Spirit Energy's 695 kWp installation at Philip Dennis Foodservice in Oxfordshire, split across a distribution warehouse and a cold store, is projected to save the business more than £85,000 a year on electricity with a five year payback and an IRR above 23%. Cold storage suits solar unusually well because refrigeration runs continuously, so almost every unit generated is consumed on site rather than exported at a lower rate. Self-consumption, not roof orientation or panel efficiency, is what drives commercial solar returns.
Solar panels are a long term investment and it's prudent to keep the system in good working order. Like a car needs an MOT, or a boiler an annual service, a much larger investment the size of a solar array is definitely worth checking periodically to ensure everything is ticking over. There are several reasons for doing this, read on for why you should get your panels serviced and cleaned regularly.
