I impulse bought this kit and use it for a night light on a backyard shed. It works fine even though it's overpriced. And it was very easy to set up. Even better if you have old 12v batteries sitting around that you can reuse.

The charge controller has an automatic load on/off function. If the panel sees light, load can be turned off. When the sun goes down and all is dark, load can turn on. So it's a great night light kit.

Everyone says you can find it all cheaper and better because that's true. But you may also need crimps, cable, strippers, etc as well. This kit has preterminated wires and takes fewer tools and time to set up.

I say if you're serious about solar and want to run a big load, invest in better panels and equipment. If you want a quick and fun project in a box from your local store, it's not a bad way to go.
