In terms of energy produced, the cost of solar panels has fallen by nearly two-thirds since 2010. In 2022, the total cost of residential solar energy systems cost $3.16 per watt, compared to $8.70 per watt in 2010.

Solar explained

Solar energy systems do not produce air pollutants or carbon dioxide. Solar energy systems on buildings have minimal effects on the environment. Solar energy also has some limitations: The availability and amount of sunlight that arrives at the earth''s surface varies depending on time of day, location, season of the year, and weather conditions

Solar explained Photovoltaics and electricity

Photovoltaic cells convert sunlight into electricity. A photovoltaic (PV) cell, commonly called a solar cell, is a nonmechanical device that converts sunlight directly into electricity.Some PV cells can convert artificial light into electricity. Sunlight is composed of photons, or particles of solar energy.These photons contain varying amounts of energy …

Understanding System Performance | Tesla Support

Once energy is produced, your solar system is designed to immediately supply that energy to your home. Any energy production not immediately needed in the home will be used to recharge your Powerwall. Only after your home energy needs have been met and your Powerwall is full will the remaining energy be exported to the utility grid.
