For many well-intentioned but not technically or financially inclined individuals, the dollars per watt value is pretty much irrelevant compared to the progress achieved. Many end users would gladly pay double for their power if they knew it was derived from renewable resources. I myself see this as a testament to what the big power companies can realistically achieve when they budget some of their billions in that direction.

Besides the obvious power generation, just imagine how many jobs have been created to maintain such an installation.
