The efficiency of a solar panel is calculated as the ratio of the electrical energy it produces to the solar energy it receives. It is typically expressed as a percentage. For instance, if a solar panel has an efficiency rating of 20%, it means that 20% of the sunlight hitting the solar panel is converted into usable electrical energy.
If the efficiency is 80 per cent, 80 per cent of the original electrical energy reaches its destination. In this case, 20 per cent of the electrical energy is referred to as power loss. The classic light bulb exemplifies how high this power loss can be. An incandescent light bulb can have an efficiency of as low as five per cent.
