Estimating daily power usage


We discussed about importance of knowing your energy consumption mix.  One of ways is to prepare a chart of all appliances in your house and then put estimated number of hours these appliances are used. You need to know how much energy is consumed by each appliance per hour. You will be able to estimate your daily power usage. This chart will also help you in planning solar installation. I have here a sample excel sheet. You can extend it to add your own appliances.
