Solar Energy on cloudy days, yes it works.
Obviously Germany’s political system endorses renewable energy much more than the USA; this is why it makes sense for Germans in even low light conditions to create energy from the sun. The truth is, even on cloudy days, a solar energy system is still creating a significant amount of energy.
Why does solar energy make so much sense in cloudy Germany and not in the sunny USA? The feed-in tariff (gives citizens generating power from the sun a guaranteed payment from the local utility company), which makes the financial payback very attractive for the people of Germany to go solar.
So get on your phone and call your representative in Congress and tell them to model our solar energy incentive programs to a working model such as Germany or Japan (who are the true leaders in installing solar energy)
