Cool stuff but that is still 3x the normal retail rate.

Cool stuff but that is still 3x the normal retail rate. Really? So the retail rate is 10 cents per watt? (excuse my ignorance)

You're confusing price per watt and price per kilowatt hour.

The quoted price is $0.30 / watt. That means that it would have to run for 3000 hours to have an average price of $0.10 / kilowatt hour. To get 3000 hours you need 250 12-hour days of sunlight. You might not get that the first year, but even if it has a two year payoff I would be covering my roof with them.

There will be some additional costs for energy storage so you can turn on a light bulb at night and use power at a higher surge rate than the sun is providing.
