How Much Energy Is Required To Produce Solar Panels

How much energy does it take to make a solar panel.

How much energy is required to produce solar panels. Recently a customer of ours raised the concern that he had heard. The amount of energy your home uses over a certain timeframe say a month is measured in kilowatt hours kwh. Assuming 12 conversion efficiency standard conditions and 1700 kwh m2 per year of available sunlight energy the u s. The solar panel with the highest watt is the sunpower e series a commercial solar panel line.

Average is 1800 alsema calculated a payback of about 4 years for current multicrystalline silicon pv systems. Solar panels work by absorbing energy from the sun transferring energy through a solar inverter and converting this energy into electricity.

When roof size is limited efficient panels with a high wattage can make the system more compact. Solar panels will never generate enough power to offset the energy that was used to manufacture them in the first place. For any given energy production target you need fewer panels if their individual wattage is higher. Starting with some conservative assumptions from a 2013 national renewable energy labs nrel report we know that it takes on average 3 4 acres of solar panels to generate a gigawatt hour of electricity over a year.

You need to know how many kwhs your home uses to determine the amount of kws your solar panels need to produce to offset your use.
