the efficiency level?
This term is used to describe the ratio of energy generated to the energy collected. For example, if a power station has to burn 1000 kW of fuel in order to generate 350 kW of electricity, the efficiency level is 35%. In photovoltaic, efficiency levels are mainly between 8% and 14%. Initially, this does not sound very high. However, if one bears in mind that the sun provides its energy as a gift just like that – then this is the highest efficiency level of all available sources of energy.
