Building a Passive House Powered by Powerwall 3 and Expansion Units​

As an early adopter of technology, Greg installed solar panels on his home 15 years ago. His goal was always to build a passive house, a home designed to be highly energy-efficient and largely self-sufficient. In 2024, he took the next step by adding Powerwall 3 and expanded his system with two Expansion Units the following year. He hasn't paid an electricity bill since.
