OT: Solar Charging 12V Car Battery

Estimate daily energy required at 200 watthours. Average solar insolation in the SW USA is about 18 megajoules per square meter per day averaged over the year. A 100 watt panel is about 1 square meter. At 10 percent electric conversion efficiency you will average about

My son, Aaron, software engineer turned farmer, has acreage in the San Tan Valley with no source of electric power.

He'd like some artificial light for his chicken coop to increase the egg output.

Lighting and timers are easy to find off-the-shelf, but I need some pointers toward finding a good quality solar panel that can charge a

Thanks in advance.

plus a Richard Simmons fitness DVD - he is almost frantic enough for the chickens to follow!

Or Bio gas. Chicken s*it is great for producing methane, but seriously adding more chickens means savings on a solar panel, controller, battery lighting and maintenance. Thats not chicken feed (pun?) and should the need to downscale happens there is no waste in investment capital (yummy!)

Practically the increased yield from a system so small that it can realistically consider car batteries is very likely to be disappointing. On the small scale it is almost always more economical to co-opt as much of nature as possible hence I bet the maths shows adding a few chickens is an outright winner in terms of economics.

He needs to crossbreed lightning bugs with his chickens, so they provide their own light. ;-)

We don't have lightning bugs here, at least in this part of Arizona. My kids were astonished upon their first trip back East. ...Jim Thompson

Either that or add a little phosphor and radium to the feed mix.

They were so deprived. :) How about Dragon flies?

And an EPA permit to dispose of their manure. :)

We know them as "Fukushima Lightbulbs."

"I saw it first but I couldn't move. You understand? It's-wait-a-minute-time when you see something like that, a light coming out of the dog dish, you follow what I'm saying? It's wait a minute time when you see something like that," says John Fairley, who first saw the bones glow.

I think I've seen them here. I think what limits certain of those bugs is lack of moisture/humidity. But I've seem wasps here that were bigger than dragonflies ;-) ...Jim Thompson

I hope your owls consider them delicacies!

I would think you'd have some bats around as well... they'd probably like to eat a wasp...

Around end-of-July into August, when the humidity goes up, the gnats appear, followed by the bats... they're fun to watch ;-) ...Jim Thompson

I've seen Dragon flies with a 12" wingspan when I was working in Destin, Florida. They get to a 4" wingspan around here, if the birds don't get them. They are supposed to eat their weight each day in Mosquitoes.

They already regulate chicken sh... uh, manure.

Maybe you could convince them that makes it 'self sterilizing'.

naaaaaaaaaaaaa.

I bet glow in the dark Easter Eggs would be a big hit, though.

From radioactive chickens? :)

There was a story in a '70s issue of Mother Earth News about a pig farm that used all their crap in a digester to produce methane, which powered the whole farm. It was used to run a small car engine, that drove a PTO generator. What was left in the digester was clean fertilizer.

Midnight egg hunts? ;-)
