Efficiency Solar Panel Types

Solar panel efficiency is a measurement of a solar panel s ability to convert sunlight into usable electricity.

Efficiency solar panel types.

What you need to know. The efficiency of the solar cells used in a photovoltaic system in combination with latitude and climate determines the annual energy output of the system for example a solar panel with 20 efficiency and an area of 1 m 2 will produce 200. An amorphous silicon solar panel is only going to have an efficiency rate of seven percent compared to 15 or 20 of the crystalline models. Solar cell efficiency refers to the portion of energy in the form of sunlight that can be converted via photovoltaics into electricity by the solar cell.

Because monocrystalline solar cells are made out of a single crystal of silicon electrons are able to flow easier through the cell which makes the pv cell efficiency higher than other types of solar panels. Factors that affect solar panel efficiency. Solar panel efficiency is a measure of how much sunlight that hits the surface area of a solar panel is converted into usable electricity. Monocrystalline polycrystalline and thin film.

Monocrystalline polycrystalline or thin film. There are three major types of solar panels. Each type has its own unique advantages and disadvantages and the solar panel type best suited for your installation will depend on factors specific to your own property and desired system characteristics. However most panels fall into one of three categories.

The highest efficiency solar panels on the market today can reach almost 23 percent efficiency. There are different types of solar panels that depending on the solar technology deeply influence the efficiency values. The average efficiency of solar panels falls between the 17 to 19 percent efficiency range. So if a solar panel has an efficiency rating of 15 that means 15 of the sunlight that hits the solar panels will be converted into electricity.

Monocrystalline and polycrystalline solar panels have very good efficiency rates. These three types of panels don t share the same efficiency rates or physical characteristics but none of the three is a clear winner in every category. Solar panels have been consistently increasing in efficiency at about 5 annually since 2010. Monocrystalline panel efficiencies can range from 17 to 22.

Each has its own advantages and drawbacks. These types of solar cells and solar panels are not quite as effective as the crystalline versions. As explained below panel efficiency is determined by two main factors.
