There are plenty of solar calculators and the brand of solar system you choose probably offers one.
Solar panel power output equation.
To operate a 18kva load you will require a 180kwh battery.
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.

Here s a simple formula for calculating your solar panel s power output.
Electrical power in kwp of one solar panel divided by the area of one panel.
The solar panel yield of a pv module of 250 wp with an area of 1 6 m2 is 15 6.
That said there is a simple equation to calculate the amount of kilowatt hours kwh your solar panel system will produce.
Solar panel watts x average hours of sunlight x 75 daily watt hours as an example let s say you have 250 watt solar panels and live in a place where you get 5 hours of sunlight per day.
To charge a 180kwh battery you will need at least 200kva power for minimum 6 hours.
Your solar panel is 148 8kwh which seems to be a little short for the battery.
Maximum pv panel solar power panel efficiency panel area radiation value 1 0 005 ambient temperature 25 degree celsius.
This is called the nameplate rating and solar panel wattage varies based on the size and efficiency of your panel.
When you mean 250 w power rating this number represents t.
Calculate the expected annual energy production.
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.
If the solar orientation and inclination correction factor is 1 1 what would be the power output.
This formula is used in literature.
Most home solar panels on the market today have power output ratings ranging from 250 to 400 watts with higher power ratings generally considered preferable to lower power ratings.
R is the yield of the solar panel given by the ratio.
Using the above equations.
Hi your panel output is 310 x 80 24 800 watts multiplying this with minimum 6 hours sunshine gives 148 800 watt hour.
Be aware that this nominal ratio is given for standard test conditions stc.
This solar panel output calculator helps you estimate the real daily energy a k a.
The stc measure the solar panel s energy output using common conditions of light exposure orientation and panel temperature.
The power output of the panels is calculated when you have the multiplication between the current and voltage of the panels when they are exposed to the weather under certain conditions.
Solar panel output is expressed in units of watts w and represents the panel s theoretical power production under ideal sunlight and temperature conditions.
