- ahi 15y agoI suspect your wind-farm energy is around 4.5 cents per kilowatt-hour edit: napkin math: .40 * 1000 watts = $400/kw Assuming 4380 hours of optimum sunlight per year and lifetime of 10 years ~= .01/kwh Should be competitive even when my ridiculous assumption meets reality.
- fryguy 15y agoPresumably, the only cost in solar panels is their construction, so there are no recurring costs (other than amortizing their lifetime). It seems complicated to figure the number of hours it lasts for, and figure out the energy generated in those hours. It's a lot simpler to figure out the amount of power generated for a given surface area (in some standardized amount of light input), and the cost of that surface area to generate. So if you wanted a kilowatt of power generated continuously from the sun, minus overcast and such, it would cost $400. I'm not an expert, but that would be my guess.
