Let me take the math another direction. It looks like David calculated a net gain of about 84,000 Wh per year. Let's round that up to 100,000 Wh per year. That is 100 kWh. Assuming electricity costs somewhere between $0.10 and $0.40 per kWh. Sounds like yearly payback is somewhere between

Bob, I think the comparison of dump pack versus roof mounted option was comparing a house mounted solar+dump solution to a *car*roof mounted solar panel, which is easy to beat in financial terms due to the cost of flexible solar for car roof and the unreliable insolation on a car. Other attempts

I think this discussion points out, though, that the money might be better placed on the house where it can lead to a bigger array, more electricity, and a better return. Of course, it probably takes a larger investment too. Mike On September 22, 2015 5:31:02 PM MDT, Robert Bruninga via EV

Interesting point. Also, the cars "draft" one another so the air resistance is quite low as well. It takes only ~0.6 HP to move per ton to propel a train 50 mph. About 5% of the energy that it takes to move a truck or a car at the same speed.

You said 1-4%. We weren't talking about solar on the house, but on the car. Wasn't that the point. I would use the S index for a comparative rate of return. *Every* rate is based on a commensurate risk, but I don't consider the S risky over the long term, and we *are* talking about long term

Agreee. Simply do the math for your application. Then compare the value of the charge to your cost. Done. Of course, everyone's value may be different. I drive around with $2000 worth of solar panels (200W) on the roof of my EV, just to make it more visibily obvious. Gets the conversations

I think it depends on why you want it. If you are altruistic and want to cut your grid usage, then it helps. If you think you'll get more range out of a charge, then apply David's calculations to the amount of Wh you'll get while on the course. Probably just a few percent more range. Peri
