context: so If I google how efficient are solar panels and it says the average is roughly 15 to 20% with the max is can get up to is 45%. my question is how is what does that mean?
In: Technology
It means that 20% of the incoming energy (in this case the light from the sun) is converted into electrical energy by the solar panel. The closer you get to 100% the better. (100% would mean all the energy is being converted)
