There more to it than just this “kit”. As the small prints says. You will also need to buy a 12 volt battery, car batteries work but a deep cycle marine battery works better, even better are two 6-vote connected in series. They last long on a charge. You will also need an inverter if you want to run any 120 stuff. This is rated for a 300 watt inverter which is not a lot of power. Won’t even power most small electric “tools”.
If all you need/want are lights I think you will get a better bang for the buck buying something like this. The specs say 2 1/2 hours of “run” time on a full charge. But how well, fast the battery charges depends on when the “charge” panel is placed.
