Around 50g of CO2 per kilowatt-hour is produced during the first years of operating a solar energy system. The solar panel’s carbon footprint is roughly 20 times less than the carbon output of coal-powered electricity sources. As a result, your carbon footprint will decrease as soon as you install solar power in your home.
However, you’ll need to have solar panels in operation for three years to become carbon neutral, paying off their carbon debt. Then, after three years of use, your overall carbon footprint will reduce further, as the system will remain carbon neutral for the rest of its lifespan.
In general, solar panels last over 25 years, keeping a significant amount of carbon out of the atmosphere.
