Solar incentives in Turkey 2026: Market Guide and Incentives

Turkey added 4.7 GW of solar in 2025 and reached 25.8 GW of total capacity by January 2026, according to pv magazine. That growth was not accidental. A stack of incentives — feed-in tariffs, auction guarantees, net metering, local-content bonuses, and tax exemptions — has made solar one of the highest-return capital investments available to Turkish businesses. But the rules changed sharply at the start of 2026. YEKDEM closed to new entrants, hourly offsetting replaced monthly net metering for many commercial facilities, and YEKA auctions began demanding higher domestic manufacturing shares. For installers, EPCs, and investors, the question is no longer whether Turkey is attractive. It is which incentive route fits each project, and how to avoid the compliance traps that turn a good return into a bad one. This guide is also a useful companion to our broader Solar Energy Turkey 2026 overview.

Solar incentives in Turkey combine YEKDEM feed-in tariffs for pre-2026 projects, YEKA auction PPAs for utility-scale plants, net metering for unlicensed self-consumption up to 5 MW, and domestic-content bonuses for locally made equipment. New projects commissioned after 31 December 2025 no longer qualify for YEKDEM.

Turkey’s Solar Incentive Stack at a Glance

Turkey does not rely on a single subsidy. It uses a layered system where each mechanism targets a different project scale and revenue model. Understanding the layers is the first step to picking the right structure.

The most important dividing line is size. Residential and small commercial projects live in the unlicensed world. Utility-scale projects compete in YEKA. The middle ground — 1-5 MW industrial rooftops and carports — is where most new Turkish capacity is being built, and where net metering rules matter most.

YEKDEM Feed-in Tariff: What Projects Still Qualify in 2026

YEKDEM (Yenilenebilir Enerji Kaynakları Destekleme Mekanizması — Renewable Energy Resources Support Mechanism) is Turkey’s feed-in tariff scheme. It guarantees eligible generators a fixed price for every kilowatt-hour they feed into the grid. For years it was the main policy engine behind Turkish solar growth. In 2026 it still matters, but only for projects that are already built.

Eligibility window

Plants commissioned between 1 July 2021 and 31 December 2025 are eligible for a 10-year YEKDEM tariff. Plants commissioned after 1 January 2026 are not eligible unless Turkey announces a new support period. That closure is the single most important policy fact for 2026 planning. Installers quoting new C&I clients should not promise YEKDEM revenue.

Base tariff and escalation

The 2021 presidential decision set the solar tariff at 32 kr/kWh with a USD upper limit of 5.1 cents/kWh, according to Özbilgin Legal. In practice the reference rate is approximately $0.05/kWh. Payments are made in Turkish Lira using a quarterly — later monthly — escalation formula that combines USD and EUR exchange rates with Turkish CPI and PPI indices. The May 2023 amendment added monthly indexation with floor and ceiling prices to protect generators from lira volatility.

Domestic-content bonus

YEKDEM includes a bonus for plants that use certified Turkish-made components. The 2021 decision set a base contribution of 8 kr/kWh for domestic components, payable for five years. Industry sources now quote an effective bonus around TRY 0.288/kWh for plants meeting current local-content tiers, according to SurgePV’s solar proposal software for Turkey benchmarks. The exact rate depends on whether modules, cells, inverters, mounting structures, cables, and transformers are produced in Turkey. Solar3GW, the Turkish solar industry association, publishes updated schedules.

How payments are calculated in practice

The YEKDEM tariff is quoted in USD for comparison, but the actual payment is in Turkish Lira. Each month the regulator applies an escalation formula that blends USD and EUR exchange rates with Turkish CPI and PPI. The result is a TRY payment per kWh that changes quarterly or monthly. This matters because the lira has been volatile. A generator that signed up expecting a fixed dollar revenue stream actually receives a lira payment that tracks a basket of currencies and inflation. The USD ceiling acts as a cap, not a floor. If the TRY depreciates sharply, the monthly escalation can push the payment up; if the lira stabilizes, the payment stays closer to the ceiling.

For developers modeling YEKDEM cash flows, the practical approach is to run three scenarios: strong lira, base case, and weak lira. The weak-lira scenario is usually the upside case for YEKDEM revenue, because the escalation formula is designed to protect generators from currency depreciation. The strong-lira scenario compresses real returns.

What happens after YEKDEM closes

New licensed projects must either win a YEKA auction or sell electricity at market prices through EPİAŞ, the day-ahead market. For unlicensed C&I systems, the economics now depend almost entirely on avoided retail electricity costs, not feed-in tariffs. That shift makes accurate self-consumption modeling the most valuable skill an installer can offer. SurgePV’s generation and financial tool models this hourly load match, which is critical under the new May 2026 rules.

YEKA Auctions: Long-Term PPAs and Local Content

YEKA (Yenilenebilir Enerji Kaynak Alanları — Renewable Energy Resource Areas) is Turkey’s competitive auction mechanism for large-scale solar. The Ministry of Energy and Natural Resources identifies zones, runs tenders, and awards long-term power purchase agreements to winning developers.

How YEKA pricing works

Winners receive the right to develop a designated area and a government-backed PPA. Recent tenders have used a two-stage price: a five-year open-market sales period followed by a 20-year guaranteed price. In the February 2025 YEKA-GES-2024 round, the guaranteed solar price was set at $0.0325/kWh, and the average zone-winning bid was $126,000 per MW, according to TaiyangNews.

2024/2025 auction results

Turkey awarded 800 MW of solar across six provinces in February 2025. The projects are in Konya, Karaman, Malatya, Van, Antalya, and Kütahya. The tender drew 146 applications from 67 companies, according to IENE. The same round was expected to generate roughly $500 million in investment and 1.5 billion kWh of annual generation. The government has said it intends to tender at least 2 GW of wind and solar capacity per year through YEKA.

Local-content requirements

YEKA tenders increasingly require high domestic manufacturing shares. The February 2025 round imposed a minimum 75% local content for modules, according to Anadolu Agency reporting via IENE. The requirement is designed to absorb output from Turkey’s growing module assembly base. For developers, this means supply-chain planning is now part of the bid strategy. For manufacturers, YEKA has created a protected local market.

Net Metering and Unlicensed Self-Consumption

Most Turkish solar capacity is unlicensed self-consumption, not licensed generation. By January 2026, unlicensed plants totaled 22.26 GW — 86% of all solar in the country, according to SHURA Energy Transition Center reporting via Solar Quarter. This segment is driven by high electricity prices and relatively simple permitting.

Residential vs C&I caps

Residential rooftop systems are capped at 10 kW. Commercial and industrial systems are capped at 5 MW. Both operate under the unlicensed generation framework and connect to the distribution network. The cap is tied to the consumption facility’s contractual power, not only the statutory maximum. A factory with 2 MW of contractual power cannot install a 5 MW system and expect full payment for the surplus.

Monthly vs hourly offsetting

For years, unlicensed plants used monthly net metering. Generation in one part of the month offset consumption later in the month. That was generous to solar, because daytime exports could cancel evening demand. A 2 April 2026 amendment changed the rule for many non-residential facilities. From 1 May 2026, facilities that received a connection-agreement invitation after 12 May 2019 must use hourly offsetting, according to Solar Load Calculator. Residential facilities continue with monthly offsetting.

Hourly offsetting means generation and consumption must occur in the same hour to receive the balancing benefit. A factory that runs night shifts will see less value from solar than one with daytime production. This change makes load-profile analysis essential.

The 2× annual consumption cap

The same April 2026 amendment introduced an annual generation cap. Annual generation should not exceed twice the facility’s annual associated consumption. Any surplus above that threshold is not paid and is treated as a free contribution to YEKDEM. In practice, this caps system sizing at roughly 100-200% of annual load, depending on the load profile. The safest approach is to target self-consumption in the 90-100% range.

A C&I system that ignores these rules can still generate electricity, but it will give away a large share of its output for free. That is the fastest way to destroy project returns.

Tax, Customs, and Financing Incentives

Beyond energy-market support, Turkey offers general investment incentives that reduce project capex and financing costs. These are not solar-specific handouts; they are standard instruments that renewable energy projects can qualify for.

Investment Incentive Certificate

Turkey’s Investment Incentive Certificate (Teşvik Belgesi) is the core vehicle. Qualifying investments can receive VAT exemption on machinery and equipment, customs-duty exemption on imported equipment, corporate income tax reduction of up to 80%, employer social-security premium support, and interest or dividend support, according to Turkish Trade Lawyers. Renewable energy equipment manufacturing falls under the Priority Investments system, which grants 5th-region incentives regardless of location.

2026 solar-specific measures

Reporting by SwissMENA indicates that in 2026 Turkey extended sovereign guarantees to solar projects above 50 MW, reduced import duties on solar PV components from 15% to 5% for projects exceeding 1 MW, and maintained corporate tax exemptions for solar investments through 2030. These measures are reported as policy updates rather than statutory law, so developers should verify current rates with a Turkish energy lawyer before committing capital.

Practical impact

For a 5 MW rooftop system, a 10-percentage-point import-duty reduction on modules and inverters can cut initial capex by several percentage points. For a 100 MW YEKA project, a sovereign guarantee can lower debt pricing by 100-200 basis points. These are not headline-grabbing numbers, but they add up across a 15-year project life.

YEK-G Renewable Energy Certificates

YEK-G (Yenilenebilir Enerji Kaynağı Garanti Belgesi) is Turkey’s Guarantee of Origin system. It issues one electronic certificate per MWh of renewable generation. The certificates are registered in a national registry, can be sold separately from the underlying electricity, and are used by corporate buyers for ESG reporting and RE100 commitments.

For Turkish manufacturers exporting to the EU, YEK-G has additional value. The EU’s Carbon Border Adjustment Mechanism creates pressure to document clean electricity consumption. A factory that covers part of its load with on-site solar, or that buys YEK-G from a nearby plant, can reduce the carbon intensity reported to EU customers. As YEKDEM fades for new projects, YEK-G becomes the main policy-based revenue stream for surplus generation beyond self-consumption.

What Solar Incentives Are Worth in Practice: A 2026 Payback Model

Incentives are only useful if they change the bottom line. Here is a realistic 2026 example for a 1 MW unlicensed C&I rooftop system in Konya.

Assumptions

• System size: 1,000 kWp
• Installed cost: $0.60/W = $600,000 ≈ TRY 19.8 million at USD/TRY 33
• Specific yield: 1,500 kWh/kWp/yr = 1.5 million kWh/yr
• Self-consumption rate: 85%
• Business electricity rate: TRY 5.95/kWh
• Surplus export price: TRY 2.80/kWh
• No YEKDEM, because the project is commissioned in 2026

Annual revenue

• Self-consumed energy: 1,275,000 kWh × TRY 5.95 = TRY 7.59 million
• Exported surplus: 225,000 kWh × TRY 2.80 = TRY 0.63 million
• Total annual benefit: TRY 8.22 million

Payback

• TRY 19.8 million ÷ TRY 8.22 million/yr ≈ 2.4 years

This is an illustration, not a guarantee. Actual yield depends on shading, inverter loading, and maintenance. Actual tariffs move with EPDK announcements and lira exchange rates. But the directional result is clear: Turkish C&I solar can pay back in under four years even without YEKDEM, because retail electricity prices are high and the solar resource is strong. The solar design software workflow that underpins this calculation — irradiance, consumption load shape, tariff structure — is what separates a bankable proposal from a guess.

Common Mistakes and Compliance Traps

The Turkish incentive system rewards careful paperwork and punishes sloppy assumptions. The four most common errors are:

1. Promising YEKDEM to new clients. The eligibility window closed at the end of 2025. Any proposal that treats YEKDEM as available for a 2026 project is wrong.

2. Oversizing beyond contractual power. Generation capacity may not exceed the consumption facility’s contractual power. The November 2025 amendment made surplus from oversized systems non-payable.

3. Ignoring the hourly-offset change. From May 2026, many C&I projects no longer benefit from monthly netting. Designers must match generation to hourly load, instead of relying only on annual consumption.

4. Missing domestic-content documentation. A local-content bonus only pays if the components are certified. Keep certificates from the manufacturer and verify they meet the current YEKA or YEKDEM tier list.

How to Structure a Project for Maximum Incentive Capture

For a typical Turkish C&I solar project, the optimal path in 2026 is:

1. Confirm the consumption profile. Pull 12 months of hourly or monthly bills. Identify contractual power, annual consumption, and demand charges.

2. Size for self-consumption. Target 90-100% annual load coverage. Do not exceed contractual power or 2× annual consumption.

3. Model hourly economics. Use a tool that simulates hourly generation against hourly load under the new offset rules.

4. Choose equipment carefully. If local-content bonuses or YEKA bids are part of the strategy, use certified Turkish-made components.

5. File connection applications early. Grid connection capacity has been scarce. Submit the application before the design is finalized.

6. Track compliance documentation. Keep manufacturer certificates, EPDK approvals, and connection agreements organized from day one.

SurgePV’s solar proposals and generation and financial tool are built for this workflow: design, self-consumption modeling, and proposal generation in one platform, with TRY/USD output for Turkish clients. You can also book a demo to see the Turkey-specific settings.

YEKDEM vs YEKA vs Net Metering: Choosing the Right Route

The three main incentive routes serve different project types. Picking the wrong one is expensive.

If you are a Turkish factory owner, net metering is almost always the right answer. If you are a project developer with a large land bank, YEKA is the route. YEKDEM is now a legacy mechanism for plants already in operation.

How the Numbers Move: TRY, USD, and the Lira Risk

Turkish solar economics are a currency puzzle. Equipment is priced in USD or EUR. Electricity savings are in TRY. YEKDEM revenue is TRY but indexed to USD. A 10% move in the exchange rate can change project returns by several percentage points.

For C&I self-consumption, a weaker lira is good for the project. The capex in lira terms rises if the equipment is imported, but the annual savings in lira also rise because electricity tariffs are adjusted upwards. Since savings are an annual recurring stream, the net effect is usually positive for projects with high self-consumption.

For YEKA projects, the PPA is in TRY with indexation. The auction price is set in USD cents per kWh, but payments are converted. Developers should model debt in TRY with a natural hedge from TRY revenues, but equity returns are exposed to real depreciation if indexation does not keep up.

The practical takeaway: always present Turkish solar proposals in both TRY and USD. It is not a nice-to-have. It is how Turkish buyers think about risk. SurgePV’s solar proposal software for Turkey generates dual-currency outputs by default.

What Oversizing Actually Costs: A Cautionary Example

Imagine a factory in Izmir with 1.5 MW of contractual power and 2.2 GWh of annual consumption. An installer proposes a 2 MW solar system, arguing that more panels always mean more savings.

Under the November 2025 rules, the system capacity cannot exceed the contractual power of 1.5 MW. The extra 0.5 MW is non-compliant. Even if the grid operator connects it, the surplus generation above the contractual-power threshold is not paid. The annual generation from the extra 0.5 MW is roughly 700 MWh. At a business rate of TRY 5.95/kWh, that represents TRY 4.2 million of avoided cost that the client never receives. The installer has sold an oversized system and damaged the project’s economics.

The same logic applies to the 2× annual consumption cap. If the 1.5 MW system produces 2.25 GWh per year against 2.2 GWh of consumption, it is fine. If consumption drops the following year, the surplus above 2× annual consumption becomes a free contribution to YEKDEM. Good installers update their models with conservative load forecasts.

2026 Outlook: Policy Signals to Watch

Three policy developments will shape Turkish solar incentives through the rest of 2026:

• YEKDEM extension debate. The industry is lobbying for a new YEKDEM window for projects commissioned after 2025. If it happens, the rate is likely to be lower than the old tariff and tied more tightly to local content.

• Floating and hybrid solar premiums. The government has signaled tariff premiums for hybrid solar-wind and floating solar projects. These could open new project structures for developers with suitable sites.

• Grid connection allocations. Connection capacity was exhausted in mid-2025 and partially reopened in early 2026. The pace of new allocations will determine how quickly the unlicensed pipeline can keep growing.

The safest assumption is that self-consumption economics remain the foundation of Turkish solar growth. Incentives help, but the core return comes from replacing expensive grid electricity with cheaper solar generation.

Frequently Asked Questions

What solar incentives are available in Turkey in 2026?

Turkey offers YEKDEM feed-in tariffs for plants commissioned by 31 December 2025, YEKA auction power-purchase agreements for utility-scale projects, net metering for unlicensed self-consumption systems up to 5 MW, YEK-G renewable energy certificates, and domestic-content bonuses for certified Turkish-made components. Tax and customs exemptions are available through the standard Investment Incentive Certificate.

Does Turkey still offer YEKDEM for new solar projects in 2026?

No. The YEKDEM eligibility window closed on 31 December 2025. Only plants that were commissioned before that date receive the 10-year feed-in tariff. New projects must rely on YEKA auctions, market-price sales, or self-consumption savings unless the government announces a new support period.

What is the YEKDEM solar feed-in tariff rate?

The YEKDEM solar base tariff is set in Turkish Lira with a USD ceiling of approximately $0.05/kWh. Payments are made in TRY using a monthly escalation formula tied to exchange rates, inflation, and producer prices. Plants using certified domestic components can earn an additional bonus, typically around TRY 0.288/kWh, for five years.

How does net metering work for Turkish commercial solar systems?

Unlicensed commercial and industrial systems up to 5 MW offset monthly generation against consumption at the same connection point. From 1 May 2026, many non-residential facilities move from monthly to hourly offsetting. Annual generation above twice the facility’s annual consumption is not paid and is treated as a free contribution to YEKDEM.

What is the residential rooftop solar limit in Turkey?

Residential rooftop solar is capped at 10 kW under Turkey’s unlicensed generation rules. Households continue to use monthly net metering after the May 2026 changes, which only apply to many non-residential facilities. Surplus credits are valued at regulated EPDK rates, not full retail rates.

What are YEKA auctions and who can participate?

YEKA (Yenilenebilir Enerji Kaynak Alanları) auctions allocate Renewable Energy Resource Areas for large-scale solar projects. Winners receive a long-term power purchase agreement with the Ministry of Energy and Natural Resources. Both Turkish and foreign-owned companies registered in Turkey can bid. Recent tenders require high local-content shares, often 75% for modules.

What is the domestic-content bonus in Turkey?

The domestic-content bonus adds a per-kWh payment on top of the base YEKDEM tariff or applies as a pricing premium in YEKA bids for projects that use certified Turkish-made solar panels, inverters, mounting structures, or cells. The bonus is tiered: more local components unlock a higher payment.

What is the biggest mistake when sizing a Turkish C&I solar project?

The most common mistake is oversizing the system beyond the facility’s contractual power or annual consumption. Since November 2025, generation above the consumption facility’s contractual power loses payment eligibility, and annual surplus above twice annual consumption is unpaid. The safest design targets 90-100% self-consumption coverage.
