Off-Grid Energy System Size Calculator

Calculate size of your home power system

Moving to an off-grid home? You will have the opportunity (perhaps necessity) of downsizing your electricity usage. To calculate how large your home power system needs to be, run the linked calculator TWICE. Compare and adjust your plans according to your budget and lifestyle.
•Run it first with numbers from your current electricity usage.
•Then run it with figures from working through the Load Evaluation Worksheet, based on the energy efficient lighting and energy efficient appliances you will choose for your new off-grid home.
