The cost for solar dropping rapidly is all over the internet. I'm not going to source it, look it up. What matters here is it doesn't need to be a "great" location in terms of efficiency in order to be a great location in terms of cost. All that matters is that whomever builds it can save more than they spend. Hence the attractiveness of parking-lot solar. Location is probably not ideal. But if the cost/kwh is low enough, it can still save a building millions of dollars over its lifespan. There are already case studies of early parking-lot solar efforts generating cost savings. Engineering efficiency is extremely overrated.
