Environmentally how long does it take to be energy neutral from the production of a solar panel?

 In

Usually within 1 to 2 years. Studies have found a solar panel makes back the energy used to manufacture it in roughly that time, and less in sunny places like Australia. Manufacturing has become more efficient over the past decade, which keeps shortening this. Because quality panels last 25 years or more, a panel generates many times the energy that went into making it. Panel recycling is also improving in Australia, which reduces the environmental cost at the end of a panel’s life.
