The standard solar panel has an input rate of around 1000 Watts per square meter, however on the solar panels available at present you will only gain roughly 15-20% efficiency at best. Therefore if your solar panel was 1 square meter in size, then it would likely only produce around 150-200W in good sunlight. [1] For example: 2 square meter panel x 1000 = 2000 x 0.20 (20% efficiency panel) = 400. 400 x 5 hours of sun hours = 2000 Watt hours per day. [ibid] In 2012, the EPA range for the 60 kWh battery pack model was 208 mi (335 km) and the 85 kWh battery was 265 miles (426 km). [2] A Tesla gets about 3.5 miles per kWh, so you would be able to get about 7 miles of driving distance per day (5 hours of sunlight) of charging.
