What happens on cloudy days?

The cost of solar energy has decreased significantly in the past 10 years, and it is now economically viable to generate solar electricity almost anywhere in the country, even factoring in cloudy days. Advanced tracking systems also enable solar panels to follow the sun throughout the day and maximize the amount of electricity generated.

You might be surprised to learn that solar panels still produce between 10-25% of their typical output even on a cloudy day.
