Does anyone know about solar power?

I really need to know what size battery I need to use with a 60 watt solar panel kit. Also how many batteries I will need. I will be using this kit with an old self contained camper. Thanks

The 60 watts is probably overstated, but let’s assume it’s correct. At 12 volts, that’s 5 amps. Generally, we try to charge a lead-acid battery at 5% of capacity, or at least 3%. That means a 12 volt, 100 amp-hour battery.

You can find gel cells equivalent to this, or just use a single car battery (deep cycle marine battery is better).

    It´s always a good idea to read the solar panel instructions, but since it sounds like you lost them try google with the legend "solar panel kits".
