I have been running a few InnoGear brand solar/motion lights and have been very happy with the light output and duration a days worth of charge lasts even on cloudy days. I am not sure what they might have for your application. I got mine on Amazon.

No flash pic of 3 of them . Garage is approx 70' from front door. Bunkhouse 30' As for deterring critters at night, only a good secure perimeter does that, occasionally.
Keeping her pups safe, build a kennel with 6' plus walls and secure roof.
The lights do a great job of illuminating the skunks, feral cats and rare coyote wandering through the property.

If she wants to pay for it, then it doesn't matter if it works or not.
Suggestions?
Get a dog that the predators will fear.
Do they have outdoor lights other than porch lights that could be switched to motion detection with halogen flood lights? They often startle critters, but most become accustomed to it and don't leave. Using halogen floods or some sort of LED flood at least lets her see. Security for pups at night means guarding/watching/caging.
If a client wants to wants to spend their money for little to no results, they are welcome to and I will take it, after discussion of limited success and consideration of more effective options.
I'm not suggesting that you just fleece her for money. I assume you'll talk to her to make suggestions based on your experience, and whats available. But, at some point, sometimes people just want what they want. My aim was to remind us that you weren't looking for suggestions about critter control, but rather which lights will stay on all night. In my experience, all those lights have either a single AA rechargeable, or a 3-pack of AAA rechargeable. So size of battery pack to have power to keep the light going all night, AND if the size of the panel can fully charge the pack during the day are what matter.
I've tossed around a similar idea with a larger panel and battery, just running a string of lights. Not always the best to have a wired system, but pretty feasible if it's all on a fence anyway.
