CO₂ evitado (kg/ano)

This calculator estimates annual CO₂ avoided by generating solar photovoltaic energy. It uses an average factor of 0.4 kg CO₂ per kilowatt-hour (kWh) generated, based on studies of emissions associated with solar energy production. To use it, input your annual kWh generation and the tool multiplies it by 0.4 to show the total CO₂ reduction for the year.

The 0.4 kg/kWh factor represents the average emissions avoided by replacing fossil fuels with solar energy. For example, a system producing 5,000 kWh/year avoids roughly 2 metric tons of CO₂. It is commonly used in residential or commercial project evaluations to justify photovoltaic system investments.

Note: The 0.4 kg/kWh is a global approximation and may vary depending on the replaced energy source (e.g., coal vs. gas). In regions with cleaner energy mixes, the impact will be lower. Always consult local data for precision, especially for official environmental reporting.
