Dr. Laurence Shalloo:

If one looks at the numbers, the land area required is not very great to get fairly big generation. I return to Dr. Upton’s point about the rooftops being the first place to start where one is not losing anything and it is a win-win situation. The question was asked as to why there has not been more of that rooftop-type stuff. If one looks at the scenario where the dairy farmer is using 50% to 60% of what they are generating, and the rest of that power cannot go anywhere, then that is not a very good economic incentive for a dairy farmer to invest in this technology. The areas are relatively small in respect of the area required, even in land-based facilities, to generate significant amounts of solar power. Dr. Upton has the numbers generated on this.
