How efficient are solar panels? (The right choice of solar panels)

The efficiency of solar panels is how much sunlight is converted into electricity. Typical solar panel efficiency ranges from 15-24%. The most efficient monocrystalline panels (20-23)%, polycrystalline (15-18)%, coated with a special thin layer (10-13)% useful efficiency. Extremely hot climates can also reduce efficiency. The ideal panel temperature is around 25°C.

Several factors affect efficiency:

The material from which the solar panel is made.
The angle of sunlight falling on the panel (useful efficiency can be increased by tracking sensors).
Ambient temperature. It is recommended to buy solar panels with an efficiency of at least 20% or more. The best solar panels usually have the best efficiency ratings.

Monocrystalline Solar Panels

Monocrystalline solar panels, also called single crystal cells, are made from the purest silicon. This type of silicon crystal is made in a complex process to produce a long rod. The rod is then cut into layers that will form the solar cells. Monocrystalline solar panels are known to provide the highest efficiency under standard test conditions compared to any other type of solar cell. You can recognize a monocrystalline panel by its rounded edge and dark color.

Polycrystalline Solar Panels

Polycrystalline solar panels, also called multicrystal cells, are slightly less efficient than monocrystalline solar panels. Therefore, it is often used in the production of cheap solar panels to reduce costs. Silicon is grown as a block of crystals, not as a single cell. These blocks are then cut into sheets to produce individual solar panels. You can recognize a polycrystalline solar panel by its square cross-section and blue mottled color.

Thin Film Solar Panels

This type of solar panel is made by covering a glass, plastic or metal substrate with one or more thin photovoltaic layers. Thin film solar panels are typically flexible and lightweight. It is known that thin film solar panels degrade slightly faster than monocrystalline and polycrystalline solar panels. The production of this type of panels is less complicated.
