How Solar Panel Produce Electricity

Also solar arrays do not generate a consistent amount of power because of variations in the amount of light hitting the pv cells.

How solar panel produce electricity.

The solar energy generated by the pv array is direct current dc electricity which cannot be used by many electronic devices or returned to the electrical grid because they use alternating current ac power. Using photovoltaic cells solar panels produce electricity. This means a steady supply of electricity as long as photons hit the solar panels. 4 factors that impact solar electricity production.

Manufacturers also make solar panels with 72 cells which are aligned in 6 columns of 12 cells each. After all solar panels use sunlight to produce energy so the amount of sunlight will directly affect the final power output. 72 cell solar panels are also 39 inches wide but average about 78 inches long. This all happens as light hits a unit called a photovoltaic cell.

Wattage is calculated by multiplying volts x amps where volts represents the amount of force of the electricity and amperes amps refers to the aggregate amount of energy used. The remarkable properties of semiconductors like silicon makes it possible to sustain the electrical imbalances. This flow travels in a circuit of wires that connect groups of solar panels called arrays. Solar panels work by allowing particles of light called photons to knock electrons from their atomic orbitals.

Unlike fossil fuels solar energy is an infinitely renewable energy source. Solar panel wattage represents a solar panel s theoretical power production under ideal sunlight and temperature conditions. Of course one of the really important factors that will affect the power output of your solar panel is how much sun it manages to get on a daily basis. When subject to sunlight photovoltaic cells create a flow of electric charge inside the solar panel due to the photoelectric effect.

Solar panels contain cells of semiconductive material usually silicon usually encased in a metallic frame and tempered glass. When this occurs a flow of electricity is generated and this electricity is harnessed and preserved as electrical energy. The current is collected by wires and carried throughout the system. Solar panels use photovoltaic cells to produce electricity according to the united states department of energy.
