More Information on Oklahoma Green Energy

Oklahoma, the sooner state, well, the sooner the better to switch over to using solar power instead of using fossil fuels for electricity. Oklahoma ranks in the top ten for average peak sun hours per day, so it is very conceivable that Oklahoma could get all its energy needs from harnessing the power of the sun.

Net metering is available in Oklahoma, but still the state lags in installed solar capacity. The sky is the limit in the future for this state, which receives ample sunlight and an above average number of peak sun hours per day.

Perhaps one day Oklahoma will use its amazing resource of sunlight and produce clean and renewable energy.

Using averages from a fixed solar panel, there are 5.59 hours of peak sun light across the state of Oklahoma. This number would vary if you were using a 1-Axis or 2-Axis tilt panel.

Taking the average daily sun light hours works well for looking at long term calculations in your area. On a daily basis this number will fluctuate due to several outside variables. For example, on a cloudy day in the winter this number would be low, but on a sunny day in the summer this number could be much higher. Looking at an average will help you calculate and plan for the output and best hours of solar insolation you can expect from your solar panels in Oklahoma throughout the year.
