How Efficient are Solar Panels?
The efficiency rating of a solar panel refers to the percentage of solar radiation that reaches the panel surface and is converted into electricity.
Most solar panels today have efficiency ratings between 15% and 20% which means they convert 15% to 20% of the available sunlight into energy.
New technologies have pushed production to 21% and 22%. This may not seem like a big jump in production but even a small increase in efficiency can have a major impact in the long term.
