I'm a bit leery about the intersection of Harbor Freight and electronics. Of 
course HF doesn't make the solar cells, but who knows what you are getting.

I purchased a 3 panel solar charger with controller... 45 watt. In full sun.Harbor freight sales. It was on sale for $145.

I believe there is a company in Scotland, called Biolume <sp?>, that is developing bioluminescence, as in deep sea fish, for commercial use, including foodstuffs. -- "For a successful technology, reality must take precedence over public relations, for nature cannot be fooled." (Richard Feynman)

Yeah, that crops up as the 'latest thing' every 10 years or so. Google invested in one just a couple years ago. Those are government subsidized too.

Not *quite* that bad. ;-) "If for any reason you are not satisfied with any item purchased, you may return the insured product within 90 days for a full refund or replacement, whichever you prefer. Shipping and handling are non-refundable." "GENERATOR RETURNS Any generator returned for any reason after the 30 day satisfaction guarantee period will be subject to a 20% restocking charge and must be returned freight paid." Don't know how they reconcile the 30/90 periods, above.

Might? For the difference it had better.

So Kalifornia to require catalytic converters on emergency generators. ?;-)

Something i learned not so long ago is that L-A batteries do much better when "conditioned" new before being placed in service. "Conditioning" amounts to fully charging and discharging down to 40 % remaining capacity or so for 4 to 6 cycles. Total capacity improvement is on the order of=20 40 % or better. ?-)

How about tiltable mirrors ? As soon as the sun gets up in the morning, a high illumination level is available immediately. In the evening, nearly full illumination levels are available until the sun sets. At noon, the mirrors could even be used as shields against the hot sun :-). Thus, the solar power would only be required to turn the mirrors during the day, instead of illuminating the chickens. Do you have any information, which wavelength would best stimulate egg laying ? If in the yellow band, low pressure sodium could be used to extend the light period, if in the blue range, blue LEDs would be the most economical way.
