Imagine you were going on a seven-day hike. You have to allow for breakfast, lunch and dinner for each day. You have to plan how much food you will want to eat so that you’re down to your last muesli bar as you hit the home straight on the final day. If you have too much food you have carried extra weight for nothing. If you don’t have enough food you go hungry. If you have the right amount of food, your hike will be an enjoyable adventure.
It’s the same when it comes to Going Off Grid. If your usage is overestimated, you could spend more money than what you need… and underestimating can lead to disaster. We know of a family who moved into their new off grid home and kept running out of power. They were so disappointed that ultimately after a long struggle they abandoned the off grid dream and hooked up to the electricity network. They could have avoided this costly scenario if their electricity usage had been accurately predicted.
How do houses use power? At the risk of sounding all-knowing… houses don’t use you power – people do. People use power by using lights and appliances in their home. If everything is switched off, no power is used.
