First, we need to know about your daily power requirements – you can help us with this by filling out the form we email you.  From the information we gather, we’ll calculate your approximate average daily power consumption and look at possible surge loads as well.
From there, based on 3 hours of average daily sunshine in winter we would work out the minimum number of panels you’d need to meet your power consumption patterns.  We then look at the minimum number of batteries required based on 2 days of power.  Finally, we’d consider the best type of inverter for your needs.
