How many kWh does this solar panel use from this link?

There are a few Solar Panels from this link but they are stating things like $2.00 per watt and $1.00 per watt. I thought we rated by kWh. So if I use an average of $.12 kWh under normal utility companies, how much would i be paying if I bought panels from this site that had the 40% efficiency rating? Is it roughly $.40 kWh? Or is it less than that and I am not reading the article right?
Again, how much does it cost? If the average user in NV uses $.12 kWh than what is a solar panel equivalent to 40% efficiency like in the link i posted?
To answer your specific questions, You buy power from the electric company in kW-hours, which is a unit of energy.
A 100 watt solar panel generates power at the rate of 100 watts. That means in 10 hours it will deliver energy equal to 100×10 = 1000 watt hours or 1 kW-hours.
“use an average of $.12 kWh” –– this makes no sense. kW-hour are not dollars. Perhaps you mean you PAY $0.12 PER kW-hour ? this makes sense.
40% means it converts 40% of the sun’s energy into power, it has nothing to do with the cost of electricity from your power company.
