Balcony PV "powerplants"

They have become popular in recent two or three years, solar panels that either feed into the existing power cable structure of the house or appartement (and need licensing by the power supplier, and many in Germany say No), you just have to plug them into a usual power wallmount like a radio, and the electricity flows into the cables in the wall and supplies all your wallmounts), or you charge a battery device of any sorts.

Often such batteries are usual car batteries, at least it is possible.

I know about the limits of chraging with sun power in winter, and even in summer on a blue sky day you ight get just 7 hours time out of it. But how much is to be expected of these things, can you maintain a refirgerator with these, a TV and maybe one or two light bulb? Charging devices for smartphones and tablets (which will be of no use of the radio towers are not electirclaly supplied, I klnow I know...)?

I have a small solar thing that is enoiugh to slowly charge a mobile powerpack as to be sued for smartphones, lets say 20mmm mAh. But the purpose I outlined? There is space for 2-3 panels, sizes of maybe 100x150 on my balcony.

I plan to get involved in this, but this is definetly new terrain for me, and I lack the electric knowledge basics.

Also, many such sets have batteries that indeed only offer two poles, but no plugions for housold plugs or USB or anything. Car batteries. Obviously a hardware interface is needed to make these batteries's energy accessible. Well, I am standing there, clueless a bit.

Anyone with experience or advice on all this? costs can be up to lets say 2000 Euros, but the stuff must be "mobile", to be set up only when indeed needed.
