Question about 100w solar panel for small devices

Mine is a 12 volt system using paired 6 volt deep cycle golf cart batteries .
Building I provided for more space than I have equipment at the time, so there is plenty of room for growth. Every component is on it's own switch; to meters, to system, and off line.
There are more common things that run on 12 volt than the higher voltages you'd have to buy more equipment to make compensations for. Including refrigerators .
RVs have refrigerators that run on AC110/, DC 12 volt, and propane. all in one unit.
Many people in RVs have a load of solar on the roof and a battery bank down below , along with a generator for the air-conditioning .
The ability to change off the resource is valuable if things get tight or changes in travel to weather conditions.
Some have 2 air-conditioning units , takes a lot of amps. ( MY fifth wheel has 2)
IMO, If your going to have 2 air conditioners ,one should be a gas driven one and save the wear and tear on the generator.
Other utilities are your washing machine and dryer and forced air heating .

 

100 watt solar panel was the thread .
9000 BTU mini split needs a 3000 watts of panel for sure @ 60* lat N & S

 

I have a 9000btu inverter split.
It's only cooling a bedroom and typically draws 2 to 2.5 amps of 240v single phase.
So if you have a split like mine yeah 3kw of panel should support it.

 

Well It depends on temp your in & how high as with latitude.

Mine is @ lat60 ,300' above datum & 25-30c max when needed

Back to OP. As you can see there are many opinions and ideas. When I started thinking about solar, it quickly became over whelming with all the info. So I purchased a HF 45 watt unit and started sorting the facts from the BS. It is a great learning tool and you can actually do more with it than you think. I have movef on with other panels and such, but my so-called HF Krap is still on my barn charging batteries, running back-up lights, small hf inverter, water pump for the greenhouse, and what ever else I can come up with. In short it really is a great learning tool.

If you can not protect what you own, it never was yours.

 

With out line meters you can't know what your getting.
Unlike a generator , solar depends on it's exposure to the sun and it's proximity in the sky. morning and after noon light are weak even using an articulator to track the sun .
Cloud cover and haze and chem trails block suns light, reducing out put . in the event of a volcanic eruption solar will be all but useless for a while . that's why I have wind mill as well.
I have other solar panels set aside in the event it becomes necessary to include them.
Back up systems are essential in a survival strategy.
Later , if my finances hold I hope to get more batteries and store them. store their acid in glass bottles and dry them out for future use .
