In an earlier post, I critiqued the reporting of First Solar and Apple’s PPA agreement involving an industrial scale solar installation. Apple CEO Tim Cook boasted that the electricity from the agreement could power 60,000 homes. The press release from First Solar, which was used rather uncritically by some reporters, was technically accurate (though a little misleading). However, there was a flaw in Apple’s calculation, using data from this document, and nobody seemed to have caught it.

The figure I calculated that reflected the actual residential delivery equivalent was 47,370 homes.

It seems as though First Solar has decided to make things clear. In an info page for the project,here, the household equivalency numbers reflect a lower estimate than Apple trumpeted: 48,000.
