Households to Receive NT$3,000 per kW for Rooftop Solar Installations from 2025

The Executive Yuan has approved the Residential Rooftop Solar Energy Installation Acceleration Plan, under which privately owned buildings with rooftop areas of no more than 1,000 square metres will be eligible for incentives to install solar photovoltaic (PV) systems from 2025. The scheme will provide NT$3,000 per kilowatt (kW) of installed capacity, with subsidies capped at NT$300,000 per project. Local governments may also provide additional incentives. 

The Executive Yuan approved the plan on 5 December as part of efforts to encourage wider adoption of rooftop solar PV among households. Running from 2025 to 2028, the programme has a total budget of NT$4.08 billion, equivalent to NT$1.02 billion a year. Funding will be provided by the Ministry of Economic Affairs (MOEA), with local governments responsible for implementation. The programme is expected to benefit around 120,000 households and stimulate approximately NT$72 billion in investment. 

Premier Cho Jung-tai told the Cabinet meeting that promoting solar PV was a key part of the government's energy policy and that there remained considerable scope for further development of rooftop solar.

Executive Yuan Spokesperson Michelle Lee quoted the Premier as saying that there had been extensive discussion of the Residential Rooftop Solar Energy Installation Acceleration Plan at the meeting.

Premier Cho said that promoting solar PV was an important part of the government's energy policy and that rooftop solar, in particular, still had considerable room for further expansion. He added that the Ministry of Economic Affairs, the Ministry of the Interior and local governments would need to continue discussions, while specific provisions under related regulations or implementation guidelines would also require further consideration. 

Deputy Minister of Economic Affairs Lien Ching-chang told a press conference following the Cabinet meeting that existing solar PV installations were concentrated mainly on large and medium-sized buildings, where deployment was already approaching its potential. The government's future policy focus would therefore shift towards smaller rooftops.

Energy Administration Director-General Yu Chen-Wei said that only around 10 per cent of buildings with rooftop areas of less than 1,000 square metres had installed solar PV systems, leaving substantial room for further expansion. 

Yu said the current cost of installing solar PV systems on smaller rooftops was around NT$55,000 to NT$60,000 per kW. The programme is intended to offset part of these installation costs, although the actual incentive received will vary depending on individual projects.

He added that some cities and counties already provide their own subsidies for solar PV installations. The central government's funding is intended to complement these local programmes and support joint efforts by central and local authorities to advance Taiwan's net-zero policies.
