why are u like this <| sep |> Its easy to guess that most of the commentators does not own their own house or have to make the financial decision on investing like this in their own home . It seems to be a simplified discussion only be about how cool it is with something new and or what the kWh price is . I would love to invest in a new environment friendly energy system not caring about other priorities in life . Giving my family the freedom to not be bound to one of the worst mismanaged , state owned company in sweden Vattenfall they only pour billions on politically motivated management and utterly bad investments abroadBUT the reality does not work like this . We cannot afford to flip flop on our investments in our house every time a new thing hits the wall . One day you will understand . I envy all that can and do they are the ones who paves the road for many of us in the future . But in reality , its not an option in a country where the electric grid covers 99 % of the population and we have not one hour of unplanned break down per year We live outside by Swedish measures any large city and prices as many has described . But it would be fun if I didn ' t have to be such a boring realist and if I had an unlimited bank balance .
