Passing by a high school today, I saw a single cabinet the size and shape of a PowerPack, wrapped in a cover which said Tesla Energy. With it was another cabinet without markings about the same size with two rectangular vents, one above the other with curved tops, on one side. There was a third box with the height and one horizontal dimension about half of the other two boxes. It had no markings either except TES was stenciled on the pallet it was on top of. Sorry, I don't have a photo, although if there is interest I might be able to get one tomorrow if they don't move the equipment. The school is having about 30,000 square feet of solar installed over their parking lot by SolarCity at no upfront cost. Presumably the PowerPack pays for itself by shifting time of usage to make it worthwhile for SolarCity (this is in California). Does one PowerPack seem like a reasonable amount of storage for that size solar facility? What might the other boxes be?
