How much lead is used in solar panels per unit of electricity generated?

Lead is used in most electronics products, including solar panels. It is an important component of the solder that connects electronic components together.

For each gigawatt hour of electricity generated, about 1.5 pounds of lead is required. In other words, if all the electricity consumed by an average person over their lifetime were provided by solar power, it would require 1.5 pounds of lead.

  • 1.5 pounds of lead per GWh
  • 0,0015 pounds (1/40th of an ounce) of lead per megawatt hour (MWh)
  • 0.0000015 pounds of lead per kilowatt hour (kWh)

Solar panels are a very small part of the 5 million tons of lead that is mined and sold each year, most of which is used in batteries.
