“He’s scaring me now,” laughs Mark Davis, as a menacing-looking ram takes a step towards him from underneath an angled solar panel. The burly operations manager is touring Manor Farm near Leighton Buzzard in Bedfordshire, where sheep are using the solar arrays for shade and a remote-controlled cleaning robot with the appearance of a mini tank steadily sloshes water down the panels.
A persistent hairdryer-like hum comes from the huge boxy green inverter, which converts the direct current electricity that the panels generate to the alternating current used by the electrical grid. This is one of about 270 solar farms that have been developed by Lightsource BP in the UK.
