I don't think you've addressed his question. GP was expecting to see a price in terms of $/W, because that's what matters to consumers interesting in purchasing panels: https://en.wikipedia.org/wiki/Price_per_watt https://en.wikipedia.org/wiki/Price_per_watt The article quotes a price in terms of $/kWh, because that's how a bid from an industrial electricity provider is stated. GP was confused / frustrated because a bid in $/kWh completely obscures the cost of the hardware, which is what he's interested in.
