In Year 115 (2026), installing rooftop solar photovoltaic (PV) systems in Taipei and New Taipei with a capacity of 1 kW or more but less than 10 kW receives a baseline feed-in tariff (FIT) ceiling of NT$5.6279 per kWh; installed in Taipei City or New Taipei City, a 15% regional premium applies, resulting in approximately NT$6.4721 per kWh, purchased for 20 years. For capital subsidies, the Taipei City Department of Economic Development grants NT$13,000 to NT$18,000 per peak kilowatt (kWp) (natural persons receive NT$3,000 less per peak kilowatt and must exceed 3 kWp capacity), capped at 150 萬 (NT$1.5 million) per case; New Taipei City combines central and local subsidies totaling NT$6,000 per kW, capped at NT$600,000 per building for standard roofs. Both municipalities accept Year 115 applications until November 30, Year 115 (2026), subject to budget depletion; check for Year 116 programs afterward. Financial viability hinges on roof space, simulated generation output, and quotation figures.
Notice: Total subsidy funds for Year 115 amount to NT$5,000,000 in Taipei City and NT$13,950,000 in New Taipei City, reviewed on a first-come, first-served basis until exhausted; call ahead to confirm remaining budget. Those applying after November 30, Year 115 must check whether economic development bureaus announce Year 116 plans, where amounts and requirements may vary. Year 116 feed-in tariffs will be newly re-announced by the Ministry of Economic Affairs; projects not completing grid connection by the end of Year 115 may be subject to different rates. All figures remain subject to the latest announcements from the Ministry of Economic Affairs and municipal authorities.
Year 115 Rooftop Solar Feed-in Tariffs
The Ministry of Economic Affairs announced on January 2, Year 115 (Jing-Neng-Zi No. 11458005630) the "Year 115 Renewable Energy Feed-in Tariffs and Calculation Formulas", effective January 1, Year 115. Solar PV applies tariffs according to the date of "completion of operational grid connection": systems completing between January 1 and June 30, Year 115 apply Phase 1 rates, while completions between July 1 and December 31, Year 115 apply Phase 2 rates; both phases share identical rates this year, purchasing electricity for 20 years. Eligible equipment covers installations that have "never received equipment subsidies from the Energy Administration, Ministry of Economic Affairs". The New Taipei program operates alongside the Ministry of Economic Affairs "Household Rooftop Solar PV Accelerated Program"; verify with Taipower prior to contracting whether subsidies affect feed-in rates. The announcement stipulates that solar PV installed in Keelung City, Taipei City, New Taipei City, Taoyuan City, Hsinchu County and City, Miaoli County, Yilan County, and Hualien County receives a 15% tariff bonus.
| Rooftop Installed Capacity | Year 115 Ceiling Rate (NT$/kWh) | After 15% Bonus in Taipei & New Taipei (NT$/kWh, calculated) |
|---|
| 1 kW to under 10 kW | 5.6279 | 6.4721 |
| 10 kW to under 20 kW | 5.3819 | 6.1892 |
| 20 kW to under 50 kW | 4.2505 | 4.8881 |
| 50 kW to under 100 kW | 4.0459 | 4.6528 |
| 100 kW to under 500 kW | 3.7152 | 4.2725 |
| 500 kW or above | 3.6236 | 4.1671 |
Bonus figures are calculated by this article using "(1 + bonus ratio), rounded to 4 decimal places" per official rules. The decree also provides supplementary tariffs in Schedule 4, such as an extra NT$0.3377 per kWh for 1 kW to under 10 kW using modules meeting "Taiwan High-Efficiency Solar PV Module Technical Specifications" from Year 115 onward, plus module recycling fees. Type III equipment (self-use under 2,000 kW) completing installation within 4 months of obtaining consent filing for the first time in Year 115 can apply the ceiling tariff from the time of consent filing. Actual rates depend on power purchase agreements signed with Taipower.

Application Workflow: From Evaluation to Subsidy Disbursement
- Confirm Rooftop Ownership Rights: Rooftop platforms on apartments and condominiums are typically common areas. Article 9 of the Condominium Administration Act stipulates common areas are used in proportion to ownership shares, while Article 8 mandates rooftop alterations comply with bylaws or resolutions of an owners meeting (區分所有權人會議); obtain consent from the management committee (管委會) or owners meeting (區權會) first. Taipei City subsidies also mandate a notarized or certified building use agreement.
- Taipower Grid Connection Review: When applying for consent filing for Type III equipment, applicants must provide a grid-connection review letter issued by power distribution utilities (Article 7 of Renewable Energy Power Equipment Installation and Management Regulations).
- File for Municipal Consent Registration: Equipment with installed capacity under 2,000 kW is verified by municipal governments (Article 4 of the same regulations).
- Building Administration Notification: Under Article 5 of "Standards for Exemption from Miscellaneous Permits for Renewable Energy Facilities", rooftop/terrace solar systems with height under 4.5 meters from roof surface (including mounting brackets) or under 1.5 meters on rooftop projections are exempt from miscellaneous building permits; boundaries cannot exceed 1 meter outside exterior wall centerlines. Article 7 requires filing consent documents and certified engineer forms before installation, with structural calculation reports required if height exceeds 3 meters, tilt angles are variable, arrays overhang exterior walls, or systems integrate new covers; Article 8 mandates structural safety and completion certificates upon conclusion.
- Contracting, Installation, Grid Interconnection: Sign power purchase contracts with Taipower prior to construction and grid link. Type III equipment must finish grid setup and apply for registration within 1 year of contract date (Article 12).
- Disbursement Application: After securing equipment registration, file documents with economic development authorities before deadlines.
Older apartments must assess waterproofing and structural capacity; verify building age using our building age Calculator. Aging distribution panels and wiring can consult our Old House Electrical System Upgrade Guide, and rooftop arrays should be part of your Pre-Typhoon Inspection Checklist.
How to Calculate Financial Feasibility
Below is our trial demonstration based on hypothetical generation figures rather than empirical double-North field data; assuming rewards do not reduce feed-in rates (New Taipei applicants should confirm with Taipower):
| Metric | Taipei City (Natural Person, 5 kWp) | New Taipei City (General Roof, 5 kW) |
|---|
| Subsidy / Incentive | 5 × NT$15,000 = NT$75,000 (capped at 49% of actual costs) | 5 × (3,000 + 3,000) = NT$30,000 |
| Assumed Generation per kW / Year | 1,000 kWh (demonstration only; insist that vendors supply site-specific irradiation simulation) |
| Annual Power Sales Income | 5,000 kWh × NT$6.4721 ≈ NT$32,360 |
| Payback Period (Years) | (Total Quotation − Subsidy) ÷ Annual Sales Income; subtract maintenance, insurance, and cleaning fees |
SOSfix recommends: obtain at least two written vendor quotes detailing specific module models, warranty coverage, simulated irradiation yields, and structural waterproofing liabilities.
Frequently Asked Questions
Do rooftop solar panels require a building permit?
Systems meeting the height and boundary limits under Article 5 of the "Standards for Exemption from Miscellaneous Permits for Renewable Energy Facilities" are exempt from miscellaneous permits, but still require administrative pre-construction filing and post-completion certification with building authorities.
Are small systems under 3 kW eligible for subsidies in Taipei City?
Taipei City subsidy brackets begin strictly above 3 kWp ("over 3 kWp"); systems 3 kWp and below fall outside the subsidy scope.
Can Taipei City subsidies be combined with other government awards?
Taipei guidelines stipulate that concurrent applications to other agencies must disclose specific items and amounts, with only one subsidy allowed per building; verify combination rules with the Department of Economic Development. In New Taipei, equipment registrations already applying for economic development solar incentives or other solar-containing schemes are barred from dual awards.
Can a top-floor apartment resident install panels unilaterally?
Rooftop platforms generally belong to common areas, governed by building bylaws or resolutions of an owners meeting (區分所有權人會議); Taipei subsidies explicitly mandate a notarized or certified building use agreement.
