Interest for the subsidies, launched in December, was "unprecedented", Steiner said.

Winners will get up to HUF 2.9 million to install solar panels and as much as HUF 11.3 mln to upgrade heating systems.

The subsidies, which targeted mostly households with below-average income, are being pre-financed by the government pending the approval of Hungary's Recovery and Resilience Facility (RRF) plan in Brussels, Steiner said.
