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.

You are still thinking 3000 pound conversions. Cut the weight and cut the

with a 1kw of solar. Imagine it at 1500 pounds with a small pack. Just do the

Doesn't that depend on how you use them? For example, lead batteries are

Wasn't that the point.
I would use the S&P index for a comparative rate of return. *Every* rate is

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.

That's 1% to 4%. Better than most banks. And FAR better for the future
since it displaces X amount of coal burning.

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 $
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
