Even if there was something lost in translation and just the solar cells by them selves took 40kwh to make that's still really good.
I hear that "solar panels will never make more energy than it took to make them" well a 220w panel should make at least 7 megawatt hours over a 20 year life.

For #1-Diesel,I've got 19,240 Btu/pound
6.942-lb/gallon (US)
133,583.32 Btu/gallon divided by 3414 Btu/kWh
= 39.128 kWh
Nice goin'!
