So I have been kicking this idea around for a while, and I think I'm going to try it. I have some vintage blow mold owl lights, and I want to convert them to Solar since some places don't have power as well as I don't like extension cords running all over the place.
so my plan is to install LED lights in them, use a small 30 watt solar panel, converter and a small rechargeable battery. then figure out how to make the solar panel and battery look non-intrusive, maybe on and in a small cooler or Tiki totum pole, or a setup I could clamp to tree.
here are some pics to give you an idea, the LED lights are .25 amp each so a little over 4 amps of power will be needed, so everything should give me 4-5 hours on light at night easily.
I really wanted to do a setup with a small solar panel on top of the owl from a yard light with a small battery inside the owl, but there is just no way to create the power needed without a stupid big panel over the owl that I can find.
We have a set of these on our carport, and I am looking for another set for the camper. They are LED bulbs which change color. The "dragonflies" are a snap-on piece that will separate from the lights. The lights may adapt to the opening in the owl globes. Sells about $30 at K-Mart.
This is a string of 20 lights, which connect at one end to a small solar recharger panel that houses 4 AA batteries. Following a good sunny day the lights will stay lit until morning. The only thing that may not work out well is the changing-color light inside of the colored owls. However if it would work, the set is compact and lightweight, and the battery pack/charger is a lot less to have to handle and keep with the camping gear.
I don't think the math works. 4 amps times 5 hours is 20 ah required. If that's the battery you're going to use it won't last long draining it to dead every night.
30 watts of solar will only give you 2-ish amps at full power. 6 hours sunlight per day (if you're lucky) will replace 12-13 ah of battery capacity, on the best days. So it would take two of those panels to keep up with the lights, and two of the batteries if you want them to last...
I'd go to Home Depot and pick up "garden" lights, one (or two, they're cheap) for each owl, and just take the guts (light, battery, solar panel) out of them and put them into the owls. All the engineering's done already, and to pack up you just put them all in a box.
'76 Shasta 2250 kept in a perpetual state of restoration. That way I don't have to buy any more campers

I'm not much technical help here, but just for comparison we use a long string of mini lights for the canopy on the Lil Loafer. It is connected to a tiny solar panel, about 4" square, with 4 AA rechargeable batteries inside. I set that up on the roof and it charges enough to light the canopy from dusk to comfortably after we crash at about 11:00 p.m. They are dead in the morning but they seem to recharge sufficiently through the day.
