Solar farm hum, cooling fans turning off and on, crows, rooks

Solar fams are becoming an increasing feature of rural soundscapes. They are not silent. They hum, cooling fans whirr turning 'off' and 'on', and circuit breakers occasionally clack to control currant flows. The sounds are not loud but constantly present when nearby. These recordings are all from an audio stream that ran for 36 hours from a hawthorn hedge (strategically planted to hide the panels from the footpath) close to the perimeter fence. It is next to one of the farm's hubs, which is the source of the humming/whirring sounds and so over exaggerates its loudness. 10 meters away it is much quieter. Wildlife is still to be seen, although late July is not a particualrly active time of year. Rabbits hop amongst the solar panels as do occasional hares. Crows and rooks fly around and small birds pass by. Buzzards and gulls can sometimes be heard overhead. Chediston Hall is a very large farm. It is run on an industrial scale - huge open fields, few hedges, extensive chemical use. Pigs are still reared intensively in sheds in contrast to the many free-range pig farms in the area. It was early to add renewable energy production to its activities. This solar farm went on-stream in 2013. This track is from late afternoon on a beautiful warm and sunny day. A cooling fan turns off, then on. Rooks call; a wood pigeon sings. The occasional dull bangs are bird scarers in distant fields.
