Taking a Gander at Solar Energy

Plans have been announced (http://www.guardian.co.uk/environment/2010/may/18/solar-farms-cornwall-silicon-vineyards) for the creation of a £40m network of solar energy farms in Cornwall and the Scilly Islands. The scheme, if approved, would involve Exeter Universities' commercial section and the Renewable Energy Cooperative of Penzance with the first potential development being the approximately 6 hectare solar Benbole farm at St Kew. The 2MW installation (it would be the UK's largest) is estimated to have the capacity to produce sufficient electrical energy for 600 homes but would be augmented by the concurrent growing of biomass crops that would be converted in an on site anaerobic digester. Where do geese come into it? They would be reportedly incorporated to keep down the grass that would otherwise reduce the efficiency of the solar panels. One wonders, however, about goose droppings?
