Shucks, thanks for the kind words.
Here are the products:
Wall/fence lights:

Pathway lights:

The lights up by the bench in the front are out of stock with no return to stock date, so I won't link them. If they come back in stock and I remember, I will (they're pretty good). The strings I put on the fence are whatever random seasonally appropriate solar string lights 20' or more I come across on Amazon.
For the wall lights, those are great because they have a fairly large solar panel with a long-ish cord that comes with both ground stakes and wall mounts, so you can put the panel 10 feet plus from the light, if needed, and mount it however gives you the best sunlight! Both the wall lights and the pathway lights tend to stay on all night from March through October, with a still-good 4-6 hours of light November through February!
For batteries, I use NiMH rechargeable batteries. I haven't had to replace any yet, so I don't know what's in the lights, but that's what I'll replace them with when the time comes. With a slow charge like a small solar panel provides, they should last for 800+ cycles (so over 2 years). I use them in my home (remotes, my outdoor thermometer receiver and sensors, other random things), and like them. Just remember that they shouldn't be tossed in the trash when dead. Most big-box hardware stores accept batteries for recycling/proper disposal, as do many natural and organic food markets. Some cities have disposal events (here in DC, you can take your "household hazardous waste" to the trash transfer station every Saturday and the first Thursday of every month).
