Business Green: “A paper published in the journal Marketing Science reports that 10 extra installations in a particular zip code increase the probability of a further adoption by almost eight per cent. They calculate that if there is a 10 per cent increase in the total number of people with solar panels in the zip code – the “installed base” – there will be a 54 per cent increase in the adoption of solar panels. Their paper also shows that the visibility of the panels and word-of-mouth led to larger installations.”
