By exporting solar energy back to the grid, we've avoided about 804 kg of CO₂ emissions. That's equivalent to 38 trees absorbing CO₂ for a full year.
A net-zero home generates as much energy over a year as it consumes. A real balance measurement, not just on paper. For De Vrijheid that means: solar energy as the engine, smart storage to bridge nights and dark days, and step by step disconnecting from fossil sources.
For you as a guest, nothing changes: warm showers, cooking, relaxing all work as you'd expect. You just know that the energy behind the meter has been generated as cleanly as possible.
Six solar panels of 485 Wp each generate more than enough on a sunny day to run the whole house and still have energy left over. The surplus goes back to the grid, or soon into the home battery.
The home battery stores solar energy generated during the day and releases it in the evening and at night. That keeps the house running on its own clean power as much as possible: less grid-dependent, even in winter.
The house no longer uses natural gas. Two heat pumps heat the house through the hot-air heating, and a heat pump boiler makes the hot water. Everything runs on electricity, as much of it as possible from our own roof.
