Off Grid Solar & Battery Storage CalculatorPlease follow the four simple steps below to get an approximation of what solar system size and battery storage system would be required to power your home off grid.Ready to get started? Simply begin with Step 1 below. Solar Calculator May 2024 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 Please enter your postcode Bedrooms Bathrooms Living Areas Light Bulb Types LED CFL Halogen Hidden Room & Lighting Calculations Hidden Total Estimate m2 Hidden Total Lighting Power Hidden Lighting Power Wh Kitchen Hidden m2 Kitchen Hidden Lighting Power Dining Hidden m2 Dining Hidden Lighting Power Hallway Hidden m2 Hallway Hidden Lighting Power Lounge Hidden Length Lounge Hidden Width Lounge Hidden m2 Bathroom Hidden Lighting Power Bathroom Hidden Length Bathroom Hidden Width Bathroom Hidden m2 Bathroom Hidden Lighting Power Bedroom Hidden Length Bedroom Hidden Width Bedroom Hidden m2 Bathroom Hidden Lighting Power Hidden Total Heating Cooling Wh Step 2: Heating & Cooling To estimate your heating and cooling requirements, select the appropriate room size where you will be running heating and cooling. You can click the "Add Another Room" button to add more rooms. Heating & Cooling Room Size 25m2 to 35m2 35m2 to 60m2 85m2 to 95m2 Estimate A/C Size Electrical Load Wh Estimate A/C Size Electrical Load Wh Estimate A/C Size Electrical Load Wh Total load Wh Hidden 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.
