That hugely depends on the region. In my corner of the world the scheme is net-billing, so homeowners are selling energy at wholesale prices.
My friend has a 10kW setup combined with a 10kWh battery. Main adjustment he made was prevent the heat pump from keeping the water hot during the night, as that was just wasting energy.
After this adjustment his electricity bills halved despite only really selling energy in the peak of the summer season. The savings translate to a 10-year return on investment before subsidies.
- pfdietz 1y agoEven this is a subsidy. Your friend was benefiting from the presence of the grid even when they weren't pulling energy from it. They still had the ability to pull energy from it when they did need. If enough people go that route then the grid will start selling this right and charge you even if you don't use it.
