At any rate, I started using the fireplace only for heat and candles for
light recently. I'm going to look into stocking the shelves with non
perishable foods and see how well I do without using the fridge for a while.
FWIW, it is fairly economical so far. I've saved at least a thousand dollars
in energy costs over the last year. When I figure out how much electricity I
consume a month at the end of this month, I'll take the $1k I've saved in
energy costs and buy some solar equipment for the apt athough I'm not in the
best place to go solar.
Thanks for your help.

I beg to differ. I'm don't like over-selling solar, but I also don't
like under-selling it. Solar electric systems can compete dollar for
dollar with the subsidized grid if you are 1/4 to 1/2 mile off the
grid.
Solar will NOT economically power the typical energy hogging
American home though.
Compared to what?
How about compared to the actual cost grid power, including cleaning
up the ground, air and water after coal-fired or nuke plants?
Solar electric systems are working for thousands and thousands of
families NOW. It's fun to dream of a time when they will be really
cheap, but I think that's pie-in-the-sky. The average home system
costs less than the average new car. I think new cars are "still way
too expensive". :)

Write your reply.

assistant: It acts like an ohmic voltage drop. It stays a relatively
constant voltage drop; but, a drop none the less.
 If this were not so, diodes would not get hot (which they
do).
 How are Zener diode wattages computed? Voltage drop times
current flowing through them. (And they can get hot)
 Try running 1 ampere through a 1 ampere diode and see how
hot it gets.
 This may be somewhat off topic; but, I feel that people
would want to know that the diode causes a small loss.
 A Schottky diode can have half the voltage drop of a
"typical" silicon diode and waste half as much power.

The typical panel around here runs at about 17 volts at max power,

That's hard on batteries. But they probably see the batteries as
expendable and replace them on a schedule.

It's more than just that, and I wish I understood it. Voltage
depends on the state of charge of the battery. A full and equalizing
12 volt battery can get up to 15+ volts. Since voltage is just
"pressure", in order for the current to flow from PV to battery, the
PV voltage has to be higher than the highest battery voltage. And
there are bound to be not only diode losses, but line losses too.
Does that muddy the waters some more?
