Welcome to the SWC AC Electrical Loads Estimation Worksheet. Feel free to use this calculator to determine your own energy consumption profile. The annual cost of the electricity consumed is based on a commercial value of $0.14/kWh. This value may not reflect your particular annual bill, but you can enter your annual bill in the box next to this value for your own record keeping interests.

If you wish to send us these values due to your interest in pursuing a quote for a renewable energy technology solution for your home / cottage / business, click on the send button at the bottom, and the values you've entered, includng your details entered below will be emailed to SWC. SWC will keep your details absolutely confidential, and will only be used internally at SWC for the purpose of contacting you for the purpose pursuing your interest in renewable energy technology solutions.

Instructions : Enter the description of the AC load and its rated wattage into the blue cells, followed by entering the hours per day the AC load is used into the yellow cells. For appliances used only periodically, such as a clothes washer (once weekly), obtain its rated wattage, the approximate hours used on "wash day" and divide the hours used by 7 (7 days per week), and insert that value into the "hours used per day" cell.
