Energy Used To Produce Solar Panel

Solar panels which convert sunlight into electricity are a key player in the fast growing renewable energy sector which also includes water and wind generated electricity the climate friendly.

Energy used to produce solar panel.

When just 4 solar cells out of these 60 are in shade the energy production might decrease by 10 percent 4. Furthermore you have to think about the energy debt involved in acquiring raw materials and converting them into the parts used to make solar panels. This all happens as light hits a unit called a photovoltaic cell. 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.

After reviewing several websites with very alarmist data i started looking around some more and found two great resources. All manufactured things that are used to make energy take energy to make. That energy that went into making the panels is called embodied energy. There s the direct use of energy to manufacture and transport the panels and their components.

Solar panels work by allowing particles of light called photons to knock electrons from their atomic orbitals. Like all manufactured objects solar panels are manufactured. Recently a customer of ours raised the concern that he had heard. The massive turbines that use the steam by boiling water by burning coal and turn that into electricity take energy to make.

Even what s needed to burn coal takes energy. That can add up fast and a lot of solar plants are using fuels like coal to generate the energy they need for activities like melting silicon. 5 hours x 290 watts an example wattage of a premium solar panel 1 450 watts hours or roughly 1 5 kilowatt hours kwh. A commonly used solar panel consists of 60 solar cells.

When this occurs a flow of electricity is generated and this electricity is harnessed and preserved as electrical energy.
