Webinar: Practical applications of the Fronius Ohmpilot.
“Mio marito ed io lavoriamo entrambi nel settore dell'energia, quindi è logico che vogliamo fare tutto il possibile per garantire che la nostra casa sia al massimo efficiente dal punto di vista energetico. Possiamo affermare con orgoglio di produrre il 98% della nostra energia durante l'estate”, spiega Miriam Gahleitner.
The Gahleitner family has built a PV system that is significantly larger than they currently require for their consumption. Thanks to their storage system, solar-energy water heating and electricity generating ÖkoFEN heating system, their average yearly power production is 93% independent from the public grid.
“The majority of the solar power that we produce during the day is stored. We only come home from work in the evening but we don’t want to feed the power into the grid. So the battery is ideal for us. The storage system means we can go the whole night without having to use power from the grid”, reports Martin Gahleitner.
With a system size of 7.8 kWp, the Gahleitner family have already thought about the future when planning the east-west PV systemand have made maximum use of the roof surface. Miriam Gahleitner is currently still charging her electric car using a 230-V domestic socket. But now there’s nothing to stop her installing a wallbox and supplying it with PV power.
The Gahleitner family is already heating its water with solar energy: namely, with the Fronius Ohmpilot. The result is that the couple can produce 98% of their power from March to October without needing to draw from the grid.
The Gahleitner family has integrated its pellet heating system into the energy system. This provides power even in the event of a blackout. The heating system can also store the energy in the BYD battery.
