Generate your own solar power and use it effectively

#solarpower #battery-storage #e-mobility
Making coffee, doing the laundry, washing the dishes – all this is possible sustainably and cost-effective with solar power from your own roof. The Reinhardt family from Ihringshausen near Kassel, Germany, has been banking on an SMA Energy System Home since 2013. The intelligent Sunny Home Manager distributes the solar power to home appliances, allowing a large portion of the generated solar energy to be consumed directly. The PV system produces twice as much as the Reinhardts need for their own use, so they want to expand with battery-storage and e-mobility. Then the family can capitalize on even more valuable PV power - especially when the sun is not shining.

Does this really make sense? I see about 50 panels and he only get 10, 000KWh per year!
It looks like he has about $30K worth of equipment. I want solar but my God that is going to take a decade for it to even break even. Then you have the stuff that is going to burn out or wear out along the way, so it's like a never ending hill.

What is the point to waste so much money just to reduce the fraction of your whole energy consumption(electricity), just for a fraction of this summ you can do:
1) use solar panels as summer sun windows shield, it will reduce overheating(AC use)
2) connect solar panels directly into a heating element of the boiler, boiler with 200 liters of the how water is 14 kwh($150) = 1 tesla power wall($3000)(and dead in 15 years) and you don't need any $6k invertors/controllecs for that
3) buy a washing machine/dishwasher with a hot water feed and actually get cheap electricity from it, (80% of washing machine/dishwasher power use is heating)
4) insulate ceiling for additional 200mm of the insulation and install heat recovery ventilation(it alone will provide x3 more saving than a chemical battery for your TV and gaming PC
5) renovate your electronics and refregerator for A+++ class
6) buy a good road bicycle for a work/study commute, it is more about your health than about driving costs, doctors does not have cheap cure for a chronical health problems

So, for the same money you can reduce 30-50% of your whole energy spending instead of the 2-7% for the electricity, yeah, let's buy a lot of chemicals just to run the old tools in a poorly insulated houses!
