Power On A Solar Panel Formula
The stc measure the solar panel s energy output using common conditions of light exposure orientation and panel temperature.
Power on a solar panel formula. Be aware that this nominal ratio is given for standard test conditions stc. Here my application is little different on solar water heater. The solar panel yield of a pv module of 250 wp with an area of 1 6 m2 is 15 6. Maximum pv panel solar power panel efficiency panel area radiation value 1 0 005 ambient temperature 25 degree celsius.
I have seen the excel sheet you have prepared for design of solar panel inverter and battery bank and it is awesome. Solar power as a function of time in kwh or wh that your solar panel can produce taking into account its rated power and solar energy available at your place. Radiation 1000 w m2 cell temperature 25 celcius degree wind speed 1 m s am 1 5. This formula is used in literature.
Electrical power in kwp of one solar panel divided by the area of one panel. R is the yield of the solar panel given by the ratio. One also specified by sayyad nojavan. Under stc a 250 watt panel produces 250 watts of electricity when the sunlight or solar irradiance on the panel is 1000 watts per square meter and the panel is operating at 25 c.
This calculator may come in handy when you buy solar panel s for your rv vehicle boat camper or home solar system and you want to get a real. I want to maintain the 70 c temperature of 50 liters approx water using 500 w dc heater for 24 7.
