One need to calculate the Total Watt Hours. It is critical to get the below calculations correct. Spreadsheet Columns explained: • Item – Appliance description • Number – Number of items • Watts – Power usage for a specific item • Hours – Number of hours the item will be on in summer • Total Watt Hours – This is the total Watt Hours for a 24hr period that will be used. In this scenario we will use 33kW (KiloWatt) of power in a 24hr window. Your scenarios may vary depending on the appliances you have. You will note that the spreadsheet excludes a traditional oven and electrical geyser. Read the section relating to “Electrical Equipment Considerations” for that discussion. Set up your own spreadsheet in the meantime to determine your specific power needs.
