We have two electric cars, and we drive a total of about 2,500 miles a month. When we charge both cars, it takes about 80kWh. Which around here would costs $17.50.
The system was about $38,500. The payback is calculated by their spreadsheet, and it includes the 30% federal tax rebate, the $1,000 Mass state rebate, electricity savings, and SREC's. The SREC's will pay us about $2,000-2500 a year.
