Remuneration usually tracks the exchange price, sometimes at a discount, sometimes fixed for one or two years. It can change substantially when the contract ends — in either direction.

For the economics this means self-consumption counts for even more than in Germany. Sizing an array close to your own demand is more defensible here than there.

OeMAG's market premium offers a subsidised route for larger systems, but it is tied to tenders and rarely relevant for households.

The threshold is higher than Germany's. The zero rate removes the old construction of opting into standard taxation to reclaim input tax and then reverting to the small-business scheme.

The relief covers systems on or near residential buildings, and on buildings serving the public good.

In practice this is the most effective answer to the missing feed-in tariff: instead of three to eleven cents, fifteen to twenty is often achievable within a community — and the buyer still pays less than to a supplier.

Switching from a fossil heating system to a heat pump attracts a federal grant that can approach full funding for lower-income households. The provinces add their own budgets, whose size and conditions vary considerably.

Because federal and provincial support stack but each has its own deadlines and caps, it pays to check both applications before commissioning the work.
