Generator V Solar Panel

Trying to decide which is the most suitable for us especially for this time of the year as we mostly do not have EHU.
All the lights are LED's which helps but blow air heating this time of year takes a lot from the batteries.
I'm not to well up on solar panels but I would imagine that one would not give much of a charge this time of year - despite our sunny climate.
A smallish Generator (900w ) run for a couple of hours would probably do ok.
Any thought anybody

During the winter in Ireland as a whole there is not much to be gained from solar panels..the majority of the 'daytime' is too
dull for them to work...so I went for a Honda 2.0i converted to gas. It will run on petrol, however all the petrol is out of it and
the lines and carb drained (so no fumes at all inside the van when transporting)....it goes onto the outside barbeque attachment
and runs from the bottle....even quieter than when running on petrol...just a whirr in the background. I have solar too btw and
have been monitoring the input...a couple of hours if lucky and perhaps 0.5 amp on average...even running the engine for a short
period does far more for the leisure battery.....lots of sites are leaning their preference towards gas generators as are some organised
meets.

Sounds good. Which model Honda is it Victor. The only experience I've had with generators have not been great, really loud ones on wildcamping spots which caused me to move on.
