Calculating solar panel efficiency
The {solar panel efficiency|efficiency of your solar panel|efficiency of solar panels} {can be calculated simply|can be determined|is calculated} by multiplying {the total wattage|the total power|your total wattage} by the {square footage of your|area of the|size of your} panel{ and| as well as|, and also} the {incident radiation flux|radiation flux that is incident|flux of radiation that hits it}. {This is multiplied|Then, multiply it} by 100. {The incident radiation flux is|In the case of incident radiation, it is simply|It is} the {amount|quantity} of {sunlight that shines on|sunlight that reflects off|light that hits} the {surface of the earth in|surface of the earth within|Earth’s surface in} {your locality|the area you live in|your area}.
In{ the|} {standard solar panel testing|normal solar panel testing|typical solar panel test} conditions, {incident|the incident} {solar radiation flux|sunlight radiation|sun’s radiation intensity} is {assumed|believed|presumed} to be {1,000|at least 1,000|1000} {watts per square meter|Watts per square meter|watts per square millimeter}.
{Let’s say, for example|For instance|Let’s sayfor instance}{, you want to calculate| you’re trying to determine| you’d like to figure out} the {efficiency on|efficiency of|power efficiency of} {your 400-watt solar panel|your solar panel of 400 watts|the 400-watt solar panel}. If {your panel measured|the panel’s area is|your solar panel measures} 2 {m2 and you use|square meters and you used|m2 and used} {standard testing conditions, then|the standard test conditions,|normal testing conditions,} {that would give you|it would yield|you’ll get} {2,000|2500|the equivalent of 2,000} {watts|Watts|power}. Divide {that number|the number|the amount} by 400, {multiply it|then multiply it|then multiply} by 100{, and you get|, and you’ll get| and you’ll have} {a 20% efficiency rating|an efficiency of 20|an efficiency rating of 20}.
400 Watt power output = (1,000 watt per sq meter x 2.25 square meters) = 20% efficiency rating
