Energy Needed To Produce Solar Panel

Solar panels will never generate enough power to offset the energy that was used to manufacture them in the first place.

Energy needed to produce solar panel. Panels produced in china which relies heavily on coal for power have a larger carbon footprint than those produced in europe. 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. After reviewing several websites with very alarmist data i started looking around some more and found two great resources. Solarreviews produces an extensive unbiased list of leading solar panel brands from around the world comparing attributes such as efficiency and warranty.

That energy that went into making the panels is called embodied energy. The essential attributes to consider are the efficiency cost warranty and technology type. The massive turbines that use the steam by boiling water by burning coal and turn that into electricity take energy to make. To get these numbers we used high and low panel production ratios to calculate how many solar panels are needed on average.

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. This will maximize the watts installed per square foot compensating the area limitation. Recently a customer of ours raised the concern that he had heard. We also assumed that the average household consumes about 10 400 kwh per year and the panels we re using are 250 watt solar panels.

Like all manufactured objects solar panels are manufactured. Fabricating the panels requires caustic chemicals such as sodium hydroxide and hydrofluoric acid and the process uses water as well as electricity the production of which emits greenhouse gases. Solar panel manufacturers need electricity and thermal energy and carbon emissions from their generation can vary widely with location. Considering 6 peak sun hours per day and 300 watt panels you need 16 to produce 700 kwh each month.

5 hours x 290 watts an example wattage of a premium solar panel 1 450 watts hours or roughly 1 5 kilowatt hours kwh. Even what s needed to burn coal takes energy. The solar panels themselves are the key elements of a solar power system.
