How much energy do solar panels produce....
- At night? ZERO! Solar panels do not produce electricity when it is dark or in bad weather. This makes solar unreliable and solar plants require 100% back up all the time by fossil fuels. In fact, battery technology doesn't exist to store even 1 day of energy in the USA. Learn more here.
- When they are snow covered? ZERO. How much snow does PA receive a year? Learn more here
What else can affect solar panels producing at 100%?
- When the days are cloudy? Only produce at 10 - 25%. Estimates range, solar panels will generate about 10 – 25% of their normal power output on a cloudy day. It would be accurate to say that solar panels do not work as well in rainy or cloudy weather.

- When the solar panels are covered by bird droppings? Depending on how much the panels are covered, energy production could drop dramatically Learn more here
- When solar panels are covered in dust? Production could drop up to 20% loss for each year not cleaned
- When the temperatures rises above 90 degrees? 10 to 25% less efficient Learn more here
Should there be a penalty for solar panels not producing what they are rated at?
- Subsidies for solar power plants are based on “nameplate ratings”.** Should there be financial penalties for solar power plants inability to deliver at least 90% of their permitted nameplate ratings on an ANNUAL basis, like their backup competitors of coal, natural gas, and nuclear power plants that provide continuous uninterruptible electricity.
- Practically every solar panel requires a backup from coal, natural gas, or nuclear, thus understanding electricity generation’s true cost is paramount to choosing and prioritizing our future electricity generating systems.
**nameplate rating is defined as maximum sustained power-generating capacity of the Generation Facility, including the continuous power output rating of any Energy Storage System.
Hopes were high that a near-miraculous source of energy had been identified..... But 45 years later, the data cannot be ignored. Sunshine makes a negligible contribution to America’s energy needs. Learn more here
