In A Solar Panel Does Sunlight Create Current Or Voltage

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.

How to design and install a solar pv system. The current output from a solar panel depends on the light intensity of the sun. 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.

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. The sunlight is a group of photons having a finite amount of energy. 5 hours x 290 watts an example wattage of a premium solar panel 1 450 watts hours or roughly 1 5 kilowatt hours kwh. 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.

The solar panels feed into the inverter system. The job of solar panels is to essentially create the electrical current. When subject to sunlight photovoltaic cells create a flow of electric charge inside the solar panel due to the photoelectric effect. This flow travels in a circuit of wires that connect groups of solar panels called arrays.

In short it really depends on the size of the panel the efficiency of each solar cell within the panel and how much sunlight your panel is exposed to.
