Instead of gasoline price guarantee, 3 years installment for photovoltaic
For each car purchaser, the installment for a photovoltaic will be 3 years paid. The photovoltaic is sized for 12000 miles per years. Chrysler organises for this a very low interest credit with only 2.5%. The photovoltaic price is $6000 per kW peak.
I estimate the Sebring for 16 kWh/100km. The photovoltaic has to have for 12000 miles = 19308 km a yearly yield of 3090 kWh. I estimate the average yearly yield in the USA with 1500 kWh per kW peak. So 2060 Watt peak photovoltaic are necessary. At $6000 per kW peak, the price would be $12357.--.
Solar electric power even in the US cheaper than gasoline
Only $793 per year would be the installment for the photovoltaic. $2379 for 3 years. Far cheaper and less risk than the gasoline price guarantee. The price guarantee covers only the gasoline price beyond $2.99. The photovoltaic installment is paid 100%, but it's very probable that the photovoltaic installment is cheaper than the gasoline price guarantee.
