Ministry of the Interior Promulgates Standards for Installing Photovoltaic Generation Equipment on Buildings
Lily Kuo/Jennifer Li/Amber Liu
On December 19, 2025, the Ministry of the Interior and the Ministry of Economic Affairs jointly promulgated the Standards for Installing Photovoltaic Generation Equipment on Buildings (the “Standards”) pursuant to Paragraph 2, Article 12-1 of the Renewable Energy Development Act. The Standards set out specific requirements regarding the entities subject to compliance, installation thresholds, exemption conditions, and application procedures for the installation of photovoltaic generation equipment on buildings exceeding a prescribed scale. Key provisions of the Standards are summarized below:
1. Scope of Applicable Buildings
Except for Category E (religious and funeral use) and Category I (hazardous materials) buildings under the Building Technical Regulations, the Standards apply to all other building categories under such Regulations (namely, Category A (public assembly), Category B (commercial), Category C (industrial and warehousing), Category D (recreational and cultural education), Category F (health and welfare), Category G (office and service), and Category H (lodging); collectively, “SolarEligible Buildings”).
2. Installation Thresholds and Calculation Method for Installed Capacity
Solar Eligible Buildings that meet the following conditions shall be required to install solar photovoltaic generation equipment with a specified installed capacity, to be installed by the builder, unless the electricity transmission and distribution enterprise (currently, Taiwan Power Company) determines that the required installed capacity may be reduced:
|
Project Type
|
Building Area
(i.e., the maximum horizontal projection area within the centerlines of the building's exterior walls or their substitute columns)
|
Required Installed Capacity ofPhotovoltaic Generation Equipment
|
|
New Construction
|
1,000 square meters or more
|
1 kW per 20 square meters of building/addition/alternation area
|
|
Additions
|
1,000 square meters or more of additional building area
|
|
|
Alterations
|
1,000 square meters or more of roof area altered
|
3. Exemption Conditions
Solar Eligible Buildings meeting any of the following conditions may be exempt from the requirement to install photovoltaic generation equipment:
(1) Buildings with insufficient sunlight
Solar Eligible Buildings may be exempt from installing photovoltaic generation equipment if their projected annual power generation per kW falls below the regional benchmarks listed below due to insufficient sunlight, as demonstrated by a power generation simulation assessment report.
|
Region
|
Benchmark
|
|
Keelung City, Taipei City, New Taipei City, Taoyuan City, Hsinchu County/City, Miaoli County, Yilan County, and Hualien County
|
543 kWh
|
|
Taitung County
|
579 kWh
|
|
Other counties/cities
|
625 kWh
|
The foregoing power generation simulation assessment report shall be issued by a professional assessment institution designated by the central competent authority and commissioned by the builder.
(2) Buildings deemed unsuitable by the building authority
Solar Eligible Buildings deemed clearly unsuitable for the installation of photovoltaic generation equipment due to structural characteristics, special occupancy purposes, or other circumstances, as determined by the building authority, may be exempt from the installation requirement.
4. Technical and Safety Requirements of Photovoltaic Generation Equipment
Photovoltaic generation equipment installed in accordance with the Standards shall comply with the following requirements:
|
Item
|
Requirements
|
|
Module
|
A test report meeting the following criteria must be obtained:
1. Issued by a laboratory accredited by the Taiwan Accreditation Foundation and showing compliance with National Standards of the Republic of China (CNS) 61215; or
2. Passing the IEC 61215 static mechanical load test with positive and negative loads exceeding 5,400 Pa (withstanding Category 17 gale-force winds)
|
|
Circuit Design
|
The equipment must be able to supply electricity to the building even when the power grid fails or when the equipment becomes isolated from the grid.
|
|
Site
|
Permanent maintenance equipment (e.g., access walkways, stairs, guardrails) must be installed in accordance with Article 29 (Work Ladders), Article 37 (Fixed Ladders), and Article 227-1 (Fall Hazards) of the Occupational Safety and Health Facilities Regulations.
|
5. Application Documents and Handover Procedures
In accordance with the Standards, the builder shall submit the relevant documents or complete the required procedures at the following stages:
|
Timing
|
Documents to be Submitted/Procedures to be Completed
|
|
When applying for the building permit
|
Drawings of the photovoltaic generation equipment or
Insufficient sunlight assessment report and documentation supporting a reduction or exemption from the installation requirement
|
|
When applying for the occupancy permit
|
Construction permit for the power generation enterprise, approval letter for self-use generation equipment, or recordation approval documents for renewable energy equipment
|
|
When applying to the transmission and distribution enterprise for inspection and power supply
|
Copy of the occupancy permit, electricity business license, and equipment registration documents
|
|
Prior to ownership transfer or handover of new building under the Condominium Administration Act
|
The builder shall complete the change of installation entity on the certification documents of the renewable generation equipment, designating the building owner, management committee, or other legally responsible management entity as the installation entity.
|
6. Consequences of Non-Compliance
Currently, the Standards and the Renewable Energy Development Act do not stipulate specific penalties. However, non-compliance may affect the issuance of building and occupancy permits, as well as the legal determination of equipment ownership.
The effective date of Article 12-1 of the Renewable Energy Development Act and the Standards is pending a decision by the Ministry of Economic Affairs. Nevertheless, future new construction, expansion, and renovation projects will be subject to the Standards regarding building management and development planning. Should your company need more information about the scope of application, compliance obligations, or practical implications of these new requirements for large-scale construction and investment projects in Taiwan or the planning and operation of solar photovoltaic businesses, the Real Estate and Construction and Energy Law teams at Lee and Li are happy to provide further analysis.
