Complete Guide to Foreign Investment
in Taiwan Solar Energy
Feed-in Tariff (FIT) rates for international investors.
Market Report • Updated: Jan 2026
With the urgent global demand for RE100 (100% Renewable Energy), Taiwan, a global hub for semiconductor and high-tech manufacturing, is seeing historical highs in demand for green energy. This guide utilizes the latest 2026 (Republic of China Year 115) Feed-in Tariff rates announced by the Ministry of Economic Affairs to help foreign investors grasp market opportunities.
1. Market Overview
The Taiwan government has released the “2050 Net Zero Emissions Pathway” and views solar photovoltaics (PV) as a core strategic industry for energy transition. The goal is to reach 40-80 GW of solar PV capacity by 2050. To achieve this, the government provides a stable feed-in tariff mechanism and related investment incentives.
Policy Goals
2025 Target: 20 GW
(Rooftop 8GW + Ground 12GW)
2050 Net Zero Path: 40-80 GW
Key Drivers
1. Strong green energy demand (RE100) from TSMC
& Tech giants
2. 20-year Government Guaranteed Purchase (FIT)
3. Support from Green Energy Technology Innovation
Policy
2. 2026 Feed-in Tariffs (FIT)
- Rooftop (1-10kW) maintains the highest rate: 5.6279 TWD/kWh.
- Identical rates for the first and second half of the year; no rush for mid-year grid connection.
- More granular capacity tiers, benefiting small and medium-sized project planning.
| Type | Capacity Tier | 2026 Rate (TWD/kWh) | Note |
|---|---|---|---|
| Rooftop PV | 1kW ～ < 10kW | 5.6279 | Highest Rate |
| 10kW ～ < 20kW | 5.3819 | ||
| 20kW ～ < 50kW | 4.2505 | ||
| 50kW ～ < 100kW | 4.0459 | ||
| 100kW ～ < 500kW | 3.7152 | Factory Scale | |
| 500kW and above | 3.6236 | Large Rooftops | |
| Ground-mounted | 1kW and above | 3.5037 | |
| Floating PV | 1kW and above | 3.8948 |
* Note: Rates are identical for Phase 1 and Phase 2. High-efficiency modules may apply for an additional bonus rate.
3. Regulations & Process for Foreign Investment
Taiwan maintains an open attitude towards foreign investment in renewable energy. According to the Electricity Act and Electricity Registration Rules, the complete project development process consists of three main stages: Establishment Permit, Construction Permit, and Licensing.
- Investment Approval: Apply for Foreign Investment Approval (FIA) from the Department of Investment Review, MOEA.
- Company Setup: Establish a subsidiary or branch in Taiwan (Special Purpose Vehicle / SPV is recommended for financing).
3-Stage Development Process
The following process applies to all utility-scale solar PV projects in Taiwan:
Stage 1: Establishment Permit (Electricity Enterprise)
This stage confirms site feasibility and grid connection conditions. Applicants submit a plan to the local government, which is then forwarded to the Energy Administration, MOEA for review.
- Key Docs: Land development consent, Taipower Grid Connection Consent, Environmental Impact Assessment (EIA) proof (if applicable).
- Validity: 3 Years (Extension possible once, max 2 years).
Stage 2: Construction Permit
After obtaining the Establishment Permit, the developer must complete land use changes or permission procedures. Then, submit an engineering plan to the Energy Administration for a Construction Permit.
- Land: Proof of Land Use Change or Permission (e.g. Urban land permission, Non-urban land rezoning).
- Equity: Proof of own funds covering at least 15% of total investment.
- Deadline: Construction must be completed within 5 years.
Stage 3: Licensing (Electricity License)
Within 30 days of construction completion, apply for inspection. Once passed, the Electricity License is issued, allowing commercial operation.
- Inspection: Document review and on-site inspection (Safety checks, relay settings, etc.).
- PPA: Signed Power Purchase Agreement with Taipower.
- Equity: Proof of own funds covering at least 18% of total investment.
Investment Incentives
Under the Statute for Industrial Innovation, foreign investors may be eligible for:
- Tax Credits: For investments in smart machinery or 5G systems.
- High-Efficiency Bonus: Additional FIT rate bonus (approx. 6%) for using approved high-efficiency PV modules.
