Step 1: Your Home
Let's begin with simple information about your home. Enter how many bedrooms, bathrooms and living areas. We use this information for an average lighting requirement calculation.

Step 1: Home Appliances
Below you can select the appliances running in your home. Under "Appliance Type" is a list of common appliances that you can choose. If your appliance is not listed, you can select "Other" and enter your own custom appliances.

Next, enter the "quantity" of appliances. For example, you might have 1 or 2 TVs'. Once you enter a quantity, our system will automatically populate average watts and hours of use per day.

If you would like to be more specific, you can also enter your exact appliance wattage and hours of use per day. Please note: Hours of use for appliances such as fridges are best left as they are. Although a refrigerator can be plugged in for 24 hours a day, the refrigeration pump may only run for 4 hours per day.
