$1/watt. Compared to a cost of about $0.10 per kilowatt-hour on my last bill means I would need 10,000 of full sunlight (10000 watt-hours = 10 kilowatt-hours for that $1) to break even. Longer if I have to pay for maintenance and a storage system.

Yea the maintenance aspect is always overlooked in these stories. If they came up with a technology that produced electricity at $0.001 per kilowatt-hour, but you had to replace them once a week, that still wouldn’t be a very good deal would it?
