It takes about 200kWh of energy to make a single 100-watt solar panel1. However, solar panels don’t require any energy to produce energy. After the “payback” phase is over, the solar panel produces energy without consuming energy. In other words, after 1 to 4 years, your solar panel has a purely net positive impact on the environment. Solar panels no longer require more energy to produce than they produce on their own2.
