Solar panel efficiency is the amount of sunlight that is captured and then converted into usable electricity.

A solar panel systems is made up of a number of solar cells placed next to one another on top of solar mounting frames and the covered by glass to make up a solar panel.

Solar cell efficiency is the amount of light that an individual solar cell converts to electricity and solar panel efficiency is the amount of sunlight that the entire systems converts to electricity.

Solar panel efficiency is important as high efficiency solar panels help you maximize your overall investment by generating more electricity with fewer panels offering you more long term savings.

An important factor to consider when comparing solar power systems is the amount of actual electricity the system can generate which is measured in kilowatt-hours.

High efficiency solar panels produce more kilowatt-hours of electricity over the lifetime of the solar system than standard efficiency panels. More electricity generated saves you more money on utility bills because you need less electricity from the local grid.

Solar panels can provide ongoing cost savings through reducing the amount of power you purchase from the grid. Most households consume around 18 kilowatts (kWh) and install solar power systems in the 1.5 to 2 kW range which displaces an average of 25-40% of the average electricity bill.
