Let''s consider an upgraded Tesla Model S with a battery capacity of 100 kWh. If you used half of its capacity daily, then you''d need a solar array of approximately 14.99 kW, which translates to 13 solar panels to offset the costs entirely. This is assuming 4 solar hours a day, which is the yearly average for the US, and 300 W panels.
