Calculate payback #21

Great module, thanks ! Just wondering if there would be a way to calculate payback time for each battery model? If we could customize each battery by specifying its retail price, as well as electricity tariff, then calculating a battery payback time could be possible... What do you think ?

Unfortunately, this is not going to be possible. The retail price is going to vary week to week never mind country to country. Also instillation costs are highly variable. I think you will have to work it out for yourself, but this should be fairly straight forward if you know how much energy you have saved.
