We have used a single unit system i e.
120 volt 20 amp solar panel.
So something like a 150 amp hours battery or battery group will be plenty for this single 120 watt solar panel.
An 120w 12v solar panel 100ah 12v battery and 120 230v automatic ups for auto on off operation of the system.
In addition to offering energy output that s more than adequate for a small rv system the solar panels in this 12 volt kit are physically flexible enough to conform to the curved roof of an rv for mounting.

This is my first instructable but i think i ve got the basics down.
It also prevents the back feed of electricity into the solar panel from the battery during hours of darkness.

The ramsond sun shield is capable of handling virtually all 12v solar panels on the market with a maximum input capacity of 24 volt and 8 amp and is perfectly suitable for most 12v rated solar panels up to 120 watt.
Best basic solar rv kit.
I chose to order all the materials online but i m sure you could find most of this stuff at radioshack.

120 watt solar panel aluminum frame ground roof mount more compact more efficient and lighter weight than the previous model.
For example if the solar panel is rated at 175 watts and the maximum power voltage vmp is given as 23 6 volts then calculate the current as 175 watts divided by 23 6 volts which is equal to 7.
Now we could have one 120 watts coulee small solar panel one 12 volts 150 amp hours battery or two 12 volts 75 amp hours batteries and a charge controller that would be our solar system ultimately.
