For the generation of electricity by the cell it must absorb the energy of the photon.
In a solar panel does sunlight create current or voltage.
This flow travels in a circuit of wires that connect groups of solar panels called arrays.
The current output from a solar panel depends on the light intensity of the sun.
Working of a solar cell.
The job of solar panels is to essentially create the electrical current.
5 hours x 290 watts an example wattage of a premium solar panel 1 450 watts hours or roughly 1 5 kilowatt hours kwh.
When subject to sunlight photovoltaic cells create a flow of electric charge inside the solar panel due to the photoelectric effect.
The absorption depends on the energy of the photon and the band gap energy of the solar semiconductor material and it is expressed in electron volt ev.
For the sake of example if you are getting 5 hours of direct sunlight per day in a sunny state like california you can calculate your solar panel output this way.
Solar panels are also considered the life blood of a solar power system because solar panels actually capture the sun s radiation thereby initiating the entire process of converting sunlight into an electrical current.
The amount of voltage or electricity a panel produces is a little complicated because there is no set amount.
Exposure to normal light for example one 250 wp 24 volt panel will show around 35 volts but no current which cannot drive any inverter.
