Vertical bifacial solar seeking greenhouse albedo, deployment space

It seems that kwh/kwp may not be the right metric for this. Key to a vertical install like that is you are going to get lower install costs per kwp, if the dual sided modules come from the factory like that, and so can be simply installed as a unit. The metric you want to go for is more like kwh per fully installed dollar. A two sided panel will have course have twice the cost for the cells, but not twice the cost for the install, and of course, a tiny fraction of the land.
