    Default Solar panel size calculator

    There used to be an awesome online calculator that worked out what your usage was versus your solar charging input based on your set up. You could manually add all the components you had (fridge, lights, water pump etc.) Went so far as to work out if you had a deficit, how many days your batteries would last before going flat.
    For the life of me, I canít find it. Could someone please share the link?

    Thanks

    There are some small niggles in the spreadsheet, but it gives some help to the user on deciding what he needs
