Solar panels are usually able to process 15% to 22% of the sun power into usable energy, depending on factors like placement, orientation, weather conditions, and similar. The amount of sunlight that solar panel systems are able to convert into actual electricity is called performance, and the outcome determines the solar panel efficiency. Which Factors Determine Solar Panel Efficiency?To determine solar panel efficiency, panels are tested at Standard Test Conditions (STC). STC specifies a temperature of 25°C and an irradiance of 1,000 W/m2. This is the equivalent of a sunny day with the incident light hitting a sun-facing 37°-tilted surface. Under these test conditions, a solar panel efficiency of 15% with a 1 m2 surface area would produce 150 Watts. The Most efficient solar panels. The highest efficiency solar panels widely available anywhere in the world in 2018 are the premium N-type IBC models manufactured by SunPower and LG Energy. SunPower X series - up to 21.5% efficiency. LG energy Neon R - up to 21.4% efficiency. SunPower E series - up to 20.4% efficiency. See the complete list in our solar panel efficiency article. Apart from the standard test conditions, solar panels are extensively tested for performance in extreme conditions. Extensive Testing of Solar Panels under Extreme Conditions  Extensive Testing of Solar Panels Under Extreme ConditionsNo single customer wants to end up with solar panels that aren't technically sound. There are major advantages to having the right type of solar panels installed for your home. In order to guarantee the quality of a solar panel, it is extensively tested under extreme conditions. WindWind is one the most predicted causes of solar cell damage. Solar panel manufacturers conduct extensive wind tunnel testing to decrease potential damage. HailHail testing consists of firing artificial hail at a speed of 20 to 30 m/s. Solar cells remain undamaged at these speeds. SnowA thick layer of snow can be too heavy for a solar panel. Solar cells stop working when more than 5 cm of snow accumulates on a solar panel and decreases solar panel efficiency by 100%. IceIce builds up on the surface of solar cells when no silicon coating is applied. The build up of ice can potentially decreases solar panel efficiency by 25 to 100%. Chemical ResidueFor chemical residue to dissolve at least 20 mm of rainfall has to land on the surface of the solar cells. Research has shown a reduction of 0.2% in solar panel efficiency when they are covered in a layer of chemical build up. UV DegradationA solar cell structure can be delaminated by UV induced degradation. Another consequence can be the discolouration of individual solar cells. Damp heat testingDamp heat testing is carried out to test the durability of solar panels in highly humid conditions. Humidity can lead to corrosion and to module connection failure and an overall decrease of solar panel efficiency. Insulation ResistanceInsulation resistance is determined by material strength. In weak materials, current leakage can occur on the edges of the solar panel. Thermal CyclingThermal cycling can cause solar panel components to fail. These components include solar cells, interconnections, solder bonds and module connections. Upon installation, it is important to consider all the factors that could influence solar panel efficiency. Moreover, it is essential to maximise output from the get go. Why Perform Extensive Testing of Solar Panel Efficiency Under Extreme Conditions?Solar panel efficiency testing is carried out in order to prevent low quality solar panels from being sold in the market. The manufacturer has to prove that the solar cells have long term durability and long term efficiency. Solar panels available in the UK market are certified by first passing extensive testing. Usually, solar cells are tested in state of the art, fully automated solar panel testing facilities. This high standard in testing enables categorisation of solar panel efficiency in groups with similar power outputs. What Types of Solar Panels Are Most Efficient?There are numerous types of solar panels. The most common types of solar panels are:
 Monocrystalline Solar PanelsMonocrystalline solar panels, also called single-crystalline cells are manufactured from the purest silicon. A crystal of this type of silicon is grown in a complex process to produce a long rod. The rod is then cut into wafers that will make the solar cells. Monocrystalline solar panels are known to deliver the highest efficiency in standard test conditions when compared to the other 2 types of solar cells. The current delivered monocrystalline solar panel efficiency stands at 22-27%. You can recognise a monocrystalline panel by the rounded edge and the dark colour. Polycrystalline Solar PanelsSolar panels made of polycrystalline solar panels, also called multi crystalline cells are slightly less efficient than those made up of monocrystalline solar cells. This is due to the nature of production. The silicon is not grown as a single cell but as a block of crystals. These blocks are then cut into wafers to produce individual solar cells. The current delivered polycrystalline solar panel efficiency stands at 15-22%.You can recognise a polycrystalline solar panel by the square cut and blue speckled colour. Thin Film Solar PanelsThin film solar panels are made by covering a substrate of glass, plastic or metal with one or more thin-layers of photovoltaic material. Thin film solar panels are usually flexible and low in weight. It is known that thin film solar panels degrade somewhat faster than mono and polycrystalline solar panels. Production of this kind of panels is less complex, thus their output is 5% less than monocrystalline solar panel efficiency. Normally, thin film cells deliver between 15-22% solar panel efficiency. Thin film solar panel technology is closing the efficiency gap with more expensive types of solar panels, therefore thin film solar panels are installed on large scale projects and in record breaking solar power plants.  Download Latest songs and videos from olamide, wizkid, tiwa savage, davido, runtown, phyno, flavour, reminisce, tekno,falz songs and videos.
