On 28th February 2025, the Federal Government and the NSW government announced the Solar for Apartment Residents (SoAR) incentive as part of the Solar Banks funding initiative. Eligible NSW strata schemes can get up to 50% co-funding for a solar system which reduces the cost of living in individual apartments, up to a maximum of $150,000 per strata building. Watch our video overview on SoAR here and read an article on SoAR here. According to Prime Minister Albanese, only 3.5% of apartment buildings in NSW have solar, which was quoted from Wattblock's Electrify Strata project!

"Wattblock's report and recommendations provided the initiative to drive some change in the building, which wouldn't have occurred without this impetus. Very impressed with the report & support you provided. A kickstart to this work. "
