150 watt solar panel for 24 ft RV

jkissing

I know I should do a power usage estimate. But is a 150 watt pannel for a 24 ft Rv used by just two people be too much. The charge should not be too much?

Thanks

Welcome to the forum.

The number of people doesn't make much difference; it's the amount of battery capacity you have. In all likelihood 150 Watts is not enough. That would just support 100 Amp hours @ 12 Volts. Chances are your RV has twice that.

Yes you really should do a power usage estimate and more. "150 Watts of panel for a 24 ft Rv .. two people" is, not enough information to estimate the 'right amount' of power generation.

May consider looking at or considering:
Does this 150 W panel nominal Voltage match your battery system? If not does the solar controller compensate for the mismatch (MPPT or non-MPPT)? If the panel does not match your battery and you do not have a MPPT controller (more costly typically) your daily harvested power will be ~50% of the potential.
Amp hour capacity of the battery (bank) being charged?
How long are you dry camping?
Watt hour or Amp hour usage per day?

For 2 people 150 Watts of solar is generally not too much, and may just be, too little.
IMHO.
