Solar Panel Yield Means

Specific yield kwh kwp is one of the most commonly used performance metrics for solar systems of all sizes.

Solar panel yield means.

Given the same amount of sunlight shining for the same duration of time on two solar panels with different efficiency ratings the more efficient panel will produce more electricity than the less efficient panel. These are both crucial things to know for anyone interested in or already using solar power. As the team behind helioscope we are frequently asked what s a good value for kwh kwp. Electrical power in kwp of one solar panel divided by the area of one panel.

Solar panel wattage represents a solar panel s theoretical power production under ideal sunlight and temperature conditions. It s used to compare different locations to analyze different designs or to assess the health of an array. It starts to get tricky when you move away from battery based solar systems and the 12v increments are no longer necessary. For example if a 300 watt 0 3kw solar panel in full sunshine actively generates power for one hour it will have generated 300 watt hours 0 3kwh of electricity.

Sometimes the energy yield is expressed in terms of the peak power of the module which is independent from the area of the module. The sun is lower in the sky in the winter. In a high yield solar area like central colorado which receives annual insolation of 2000 kwh m 2 year 1 such a panel can be expected to produce 400 kwh of. Unfortunately solar panels don t generate a steady stream of electricity all day.

The energy production of an individual solar panel over a time period installed in a specific place measured in kilowatt hours kwh. Grid tie solar panels with 60 cells are often referred to as 20v nominal panels like the solarworld sunmodule 290w solar panel. A solar panel can produce more when the sun is high in the sky and will produce less in cloudy conditions or when the sun is low in the sky. Solar panel efficiency is a measurement of a solar panel s ability to convert sunlight into usable electricity.

They have too high of a voltage to charge a 12v battery bank with a traditional charge controller but too low of a voltage to charge a 24v. This is a very useful ratio since the energy yield e is a measure of the earnings potential while the peak power reflects the cost of the system. That same 300 watt panel produces 240 volts which equals 1 25 amps. Solar panel production at a specific place like your roof.

Once again if the panel in question has a yield of 250 wp and is 1 6 meters squared in surface area the overall efficiency would be 15 6 h global radiation value this is the global radiation value or the average amount of sunlight based radiation which your area of the world receives. It is with h 0 1 000 w m 2.
