I have just spend the last 2 days trying to make a calculator for designing off grid solar systems.
Here it is:
Although I live off grid I am a total non expert on the mathematics of solar power systems. I have trusted in the fact that Sunking knows what he is talking about and I have used two of his tutorials for inspiration.
Hopefully I have not made any mistakes.
One area which concerns me is that SUNKING states.
"To figure the daily load, go back to the original load number before the fudge factor—that is, 6000 watt hours."
That means that when we calculate battery requirements we don't use the fudge factor????
Is that correct?
The main reason why I have spent the time making this calculator is because in another thread everyone told me that my system has massively undersized batteries. This is surprising because I am happy with my system.
Using the calculator it is possible to explain why I am reasonably happy. It is because I have a very big difference between maxmum power partytime and times of batten down the hatches minimalism. Also I have shut down my freezer for the winter and put the food in another house.
The default settings for the calculator are the ones from my house.
I have thought about adding more functionality such as a
Pay back time calculator.
Anyway I would appreciate it if anyone has any feedback and I hope it may be useful for other people.
If there are any concrete suggestions for improvement I would probably follow them up.
