Solar tariffs and regulations in Türkiye
Netting (mahsuplaşma), the paid production limit and surplus purchase by the assigned supply company. Türkiye rewrote its rooftop billing rules in 2026, and solarVis models both regimes.
Every market, every tariff, built in
Net metering, net billing, credit carry-over, feed-in tariffs and hourly or monthly netting all live in the tariff configurator, alongside time-of-use, tiered and demand charge structures. Tune currency, seasons, export rates and VAT, or build a brand-new tariff structure when a market changes the rules. Pre-built for the US, UK, Germany, Türkiye, South Africa, Italy, Spain, France, Poland and the Netherlands.

Netting is hourly for businesses, monthly for households
Since 1 May 2026, non-residential unlicensed plants settle production against consumption hour by hour, so midday surplus no longer cancels an evening import. The residential (mesken) group kept monthly netting.
Paid production limit
Production evaluated for payment is capped at twice the associated site's annual consumption. Anything above that is fed in as a free contribution to YEKDEM and carries a system usage charge. The residential group is exempt.
Surplus purchase and the export-side distribution fee
Surplus left after netting is bought by the site's assigned supply company (GTŞ) for ten years from commissioning, at a regulated price. An export-side distribution fee, set by EPDK at 65.6008 kuruş per kWh, is deducted from every exported kWh.
Tiered residential tariff and the 4,000 kWh threshold
Households pay a subsidised rate on the first 240 kWh each month and a higher rate above it. A household consuming more than 4,000 kWh a year moves onto the last resort supply tariff (SKTT) for the following year, at market-indexed prices.
01What changed for Turkish businesses on 1 May 2026?+
Netting moved from monthly to hourly for every non-residential unlicensed plant. Each hour settles on its own, so a model built on monthly totals overstates self-consumption and shortens payback. SolarVis applies hourly netting when hourly load and production data are available, and falls back to monthly netting otherwise.
02Do households net hourly as well?+
No. Production tied to a residential (mesken) subscription still nets monthly, and the paid production limit does not apply to that group. A residential rooftop and a commercial rooftop are now on two different billing regimes and cannot share one feasibility template.
03Is the surplus sold to the state?+
Not directly. Article 5(2) of the unlicensed generation regulation brings surplus into the scope of YEKDEM, but the buyer is the site's own assigned supply company, which is obliged to purchase it at a regulated price for ten years from commissioning.
04Does solarVis model single-time and multi-time tariffs?+
Yes. Single-time and multi-time (çok zamanlı) variants are preloaded for the residential, commercial, industrial and agricultural consumer groups, with daily periods running 06:00 to 17:00, 17:00 to 22:00 and 22:00 to 06:00. Every rate stays editable per project.
