Subject: OT O.T. Solar "tech-head" question
Hi, All,  I don't know where to ask this; also tried Google but dunno how
to phrase the Q. so as to get fewer than 50,000+ hits...

What i'm wondering is wherer tehre is a basic/beginner's/'how to" book that
will tell me how to build simple solar-powered items.  The thing is that I
am *not* an electrician, never studied electronics, don't want to rewire a
whole house, etc. - I just want to find out (1) how to match the power
output of cells and the power requirements of simple things (lights,
mostly), and (2) how to put them together - not "how to solder", as I know
that; but how to connect the above-mentioned and matched components.

Basically, does anyone know whether is there a sort of "solar cookbook"
that will bypass the things I don't want and tell me how to build or wire-
together a variety of simple lights (or maybe clocks and other *simple*
items) - or, alternately, a source for this sort of basic information?  

Most of my hits were retailers of completed units, OR components retailers
(but no instructional material that I could see).

Thank You!!

- Kris

There used to be a general site I would go to about the general stuff but I
can't seem to find it now.  Is there anything useful here:

First off, there's been a terrible misconception thrown around for a long
time which has lead to alot of confusion on this subject.
Let me get this part out of the way first: the book.
There is no book that I am aware of that dispells the popular myths about
solar.
There are books that will *teach* you how solar stuff works, but why pay
money when you can get the info for free on the web?
Here's the deal, are you sitting down?
Solar doesn't *power* stuff.
Photovoltaic solar cells simply recharge batteries.
And then the solar recharged batteries can then power stuff.
Thats the simplest explanation you'll find anywhere.
From that point on it gets exponentially more complex.
Everything I've read, or was told, says the same thing: first find out how
much power you require for any given task.
Say for example you just want a simple *solar powered* lamp over your desk,
sounds easy right?
When you run the numbers of the costs of whats involved you'll be
flabbergasted.
Take it from me, its far, far cheaper to just get a $10 lamp at Walmart and
plug it in the wall.
On one end of the string you have your PV panel and on the other end you
have your desk lamp and in between there are a whole buncha dollar signs to
make it happen.
Unless you just go out and buy a $50 solar lamp thingy at Lowes or wherever
that you sit in the yard you're going to find solar stuff in general is
hugely expensive.
None of it is cheap.

Here in my office I have a computer and a lamp that I wanted to put on an
*entry level* solar system that I could expand at a later date.
No way.
It would cost me over $2,000 right up front just to get the thing started.
If I reverse engineer the power grid costs of running my computer and lamp
it would take me 20 years to recognize any benefit and unfortunately the
solar products won't last that long.

From what I've seen the real solar users in the US fall into 2 categories
and both have lots of money.
Well, maybe 3 categories.
1) The Ed Begleys that have zillions of dollars and no brain power, so he
throws wheelbarrow loads of coins at the thing to assuage his media
purchased guilty ass conscience.
2) Wealthy people that live in isolated areas where a power grid is not an
option.
3) Less than wealthy people can live off the grid too but they have greatly
modified their lifestyle so that electricity is not a major necessity to
them, sort of like living 200 years ago, candles, fires, going to bed when
the sun goes down, no TV, library computer usage, etc.

If you want to know anything else about this stuff you can ask me, I'm no
expert but I have learned a few things, or lurk in alt.solar.photovoltaic or
alt.solar.thermal or alt.energy.homepower.
I've been hanging out in those groups for a couple years and there's a
wealth of info to be found there.

You'll need a solar cell, a battery and the lamps....connected in that
order.
I would suggest you do that which you don't want to do, for educational
purposes.
Buy a pre-made set up and take it apart and study it, pay attention to the
teeny model/serial numbers, manuf. names, etc. and search them on the web
and then try to find other sources that are comparable.
I did that 6 years ago with a floating water lilly fountain my wife bought
for the pool. It worked for a week then stopped so it landed on the
workbench and Dr Don took an assortment of specialized instruments to it to
find out why it didn't tick.
I found out that the battery compartment wasn't waterproof and the batteries
(2-C batteries) shorted out.
Becasue of the way it was built there was no way to make the battery
compartment waterproof, and still be able to change the batteries, so I
installed 2 new batteries and siliconed the lid shut and threw it back in
the pool. It was still functioning when we sold the house in 2006.
For something simple like that the chain goes like this:
solar cell --> battery pack ---> pump, lamp, chime, whatever.
(hint: its not possible to have a solar cell thats too big)
Another hint: scope out some of the surplus sites, like science surplus,
miltary surplus, electronics surplus, hell, solar surplus and see what turns
up.
Me?
I watching locally for someone to sell a residential solar panel (150 watts
or so) for $100 or less that I can play around with.
The hot tip is to get ahold of a 6 volt golf cart battery, then you can
really start getting stuff done.

Well, that's cool - OTOH, the batteries ought to discharge completely
through the course fo the night, whcih seems to be one of the "rules of

I thought that the abtteries had to be large enough to handle the input
from the solar cell(s) - which is one of the mystifying parts - i.e.,
what are the "rules of thumb"...

Well, for now, I just want to see whether it'd be profitable to make
stained-glass garden lights ;)

Right.  Same tends to be true of wind (and I say "tends" only because I'm
not absolutely cwertain that wind turbines "never" work any other way...)

But what's the rule for balancing solar cell output, to battery
capacity...?

The whole point, tho', for me personally at this time is to see whetehr I
could do stained glass garden lights.  Yeah, you can buy all sorts fo
solar lights (from cheap black plastic things, to stainelss steel and
otehr emtal units, to silly/cutie glowing resin animal charicatures), but
what I'm interested in doing is "stepping it up a notch" and dong a hand-
crafted thingy that's unusual - for example, a design using variously-
textured clear glass the way one uses lines and whatnot in doing
pen'n'ink drawings, larger than typical path lights (i.e., more LEDs) and
acting as a sculpture that attractively catches sunlight by day, and just
happens to have lights in it for nighttime viewing.

I'm certainly no stranger to WalMart, but I want to *make* something (if
I can figure out the lighting part), and specifically, try to make
something beautiful, or at least unusual, that people might be interested
in buying.

Neither are hand-crafted stained glass objets d'art - "cheap" isn't my
point in this.  I can estimate how long it'd take me to do the glass
parts, but I also need to know what sorts fo parts I'd need, and how
toassemple them, before I can make any sort of estimate regarding my
costs (and therefore, reasonable profit margin) for that part.

What it is, is that I'd like to at least try to see whether I could make
some things that would harmonize with a given house style, IOW, somehting
that's more stylistically individualized - the target audience being
people who care about that sort of thing.

4) people who are just interested,IOW, natural "tech-heads" ;)  
5) people who want to have some light in the yard without stringing
electrical wires all the heck over the place ;)

I'm going for the arsty-fartsy subgrouping of #5 <g!>

Oh!  OK, good idea, for some reason (well OK, lack thereof!) I never
thought of checking the newsgroups...thanks!
