Solar farm at Cambridge, Gloucestershire

I was peering through the hedge at this solar farm in Gloucestershire. Data shows that it receives 1000kWh per square metre per year. Say one panel is 2 metres wide and 10 metres long. Say 20 rows of 10 panels. That is 4 million kWh per year. If a typical medium consumption home uses 3300 kWh per year (https://www.ofgem.gov.uk/ofgem-publications/64026/domestic-energy-consump-fig-fs-pdf) then this field could power 1000 homes. I need to get more accurate figures for size and number of panels,
