Solar power would be very useful. Either to power the car directly or to replace Eskom's coal-powered power. But that's not really an option, is it?I like the Joule concept but it has a sticky point as all electric or hybrid vehicles do: PRICE
Here is a estimated price break down based on some of the details from this article:
http://www.itweb.co.za/index.php?op...-to-drive-in-2012&catid=69:business&Itemid=58
- Joule base model : R240 000
- Monthly battery leasing equating to about two tanks of fuel : R749 (50 litres 93 ULP * 7.49 * 2 tanks)
- Cost to recharge batteries at home in Tshwane (74.2 cents/kWh): R326
Assumptions:
- Distance traveled between JHB and PTA is 100km per day for 22 days per month
- Average power consumption for 100km is 20kW for 1 hour = 20kWh
- Charging efficiency of charger and battery is 100%
So the real operating cost fuel wise is R985 per month but with Eskom's tariff increases it could be closer to R1629 per month in 2-3 years time.
The repayments over 6 years with a 20% deposit, prime -0.5% and no balloon payment is going to be R4446 per month.
Add on at least R500 for insurance
Total cost at current electricity prices: R5931 per month
Total cost at R2.0 per kWh : R6575 per month
Maybe that's affordable for some people but my second hand car repayment plus fuel plus maintenance costs plus insurance is about half that amount.
