    The stand alone pv tab lets you work out what you need, just wondering how accurate it looks?

    if you hang a 100W panel expect to average 300Wh a day seasonally.
    300Wh = 25Ah

    Know your daily expected loads.

    Battery size = (((daily loads - solar input) x days of autonomy required) x 2) + 20%
