How Solar Panel Produce Electricity

Solar panels work by allowing particles of light called photons to knock electrons from their atomic orbitals.

How solar panel produce electricity. Solar panels use photovoltaic cells to produce electricity according to the united states department of energy. Using photovoltaic cells solar panels produce electricity. 4 factors that impact solar electricity production. Solar panel wattage represents a solar panel s theoretical power production under ideal sunlight and temperature conditions.

Manufacturers also make solar panels with 72 cells which are aligned in 6 columns of 12 cells each. Unlike fossil fuels solar energy is an infinitely renewable energy source. The semiconducting materials energize when photons or sunlight hit the panels. These cells are sandwiched between semi conducting materials such as silicon but it can also be glass or polymer resin with different electronic properties to create an electric field.

The remarkable properties of semiconductors like silicon makes it possible to sustain the electrical imbalances. When subject to sunlight photovoltaic cells create a flow of electric charge inside the solar panel due to the photoelectric effect. This means a steady supply of electricity as long as photons hit the solar panels. Also solar arrays do not generate a consistent amount of power because of variations in the amount of light hitting the pv cells.

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. The cells are where electricity is made and the wires carry the electricity to a junction box where the panel is hooked into a larger array. 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. Solar panels contain cells of semiconductive material usually silicon usually encased in a metallic frame and tempered glass.

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. This flow travels in a circuit of wires that connect groups of solar panels called arrays. 72 cell solar panels are also 39 inches wide but average about 78 inches long. The current is collected by wires and carried throughout the system.
