Slovak Innovation and Energy Agency (SIEA) administers the Zelená domácnostiam programme funding residential solar PV, battery storage, heat pumps, and biomass boilers. Recent rounds offered €500/kWp installed capacity for solar PV (capped at 3 kWp / €1,500 per household) plus battery and heat pump supplements.
Zelená domácnostiam (Green for Households) is Slovakia's main residential renewable energy grant programme, administered by Slovenská inovačná a energetická agentúra (SIEA, Slovak Innovation and Energy Agency) and co-financed under EU Recovery and Resilience Facility and Cohesion Policy operational programmes. The programme runs in time-limited tranches with substantial oversubscription — applications often hit the daily cap within hours of opening. Solar PV component: €500 per installed kWp for systems up to 3 kWp, capped at €1,500 per household. Additional supplements available for battery storage and heat pump bundles. The programme has been intermittently paused and re-opened across 2023–2026 as funding is drawn down; confirm current availability at zelenadomacnostiam.sk before contracting an installer.
Slovak distribution system operators (Západoslovenská distribučná, Stredoslovenská distribučná, Východoslovenská distribučná) operate residential prosumer schemes under URSO-approved tariffs. Energy compensation is at retail tariff (energy component); distribution charges are billed regardless of export.
Slovakia's distributed-generation framework is supervised by Úrad pre reguláciu sieťových odvetví (URSO, Regulatory Office for Network Industries). Three distribution operators serve the country: Západoslovenská distribučná (ZSD, western), Stredoslovenská distribučná (SSD, central), and Východoslovenská distribučná (VSD, eastern). Residential prosumers under 11 kW (single-phase) or 30 kW (three-phase) operate under the small-source local-source compensation scheme: exported energy credits at the supplier's retail energy component (typically €0.08-€0.11/kWh excluding distribution) while distribution charges remain billed monthly. The framework provides modest export compensation but is materially less generous than 1:1 net metering. Confirm tariffs with your supplier (ZSE/SSE/VSE retail or competitive supplier) before sizing a system.
Slovakia applies the standard 23% DPH (VAT) rate on residential solar PV equipment. Reduced 5% rate applies to qualifying social construction work but rarely covers private residential PV retrofits.
Slovakia's 23% standard Daň z pridanej hodnoty (DPH) rate applies to residential solar PV equipment. Finančná správa SR (Slovak Financial Administration) administers the regime. The reduced 5% DPH rate that applies to social construction work extends to renewable energy components in qualifying social housing projects but does not cover private residential retrofits. Combined with relatively moderate retail electricity rates (€0.16-€0.20/kWh residential, with regulated tariff caps for low-income households) and meaningful Zelená domácnostiam grant support when available, Slovak residential solar economics depend heavily on grant capture. Without grant support, payback typically extends beyond 11 years on a 5 kWp system given the moderate solar resource (~3.0-3.8 peak sun hours).
