Solar panel system cost in Slovakia: installed prices
Sources checked
Compare the price of a complete installed system before subtracting support. The Slovak guide records nine dated package examples from three sellers, checked on 21 October 2026. These observations are not a national market average or a quote for your roof.
What the recorded packages show
EnergyInvest advertised 5.225 kWp, 7.125 kWp and 9.975 kWp packages without a battery at €6,450, €7,300 and €8,400 including VAT. The corresponding packages with a nominal 16 kWh Deye SE-F16 battery were €8,650, €9,500 and €10,600. All these figures were before support.
SolarGO's advertised packages without a battery were €6,458 for 5 kWp and €7,750 for 8.26 kWp, including VAT. Its advertised prices after support must be checked against the programme and eligibility applicable to the buyer. Different packages can include different inverters and installation work.
The ninth example was Energovision’s “10 10 10” package: 19 × 535 Wp panels (10.165 kWp), a Solinteg MHT-10K-25 10 kW inverter and a nominal 10.36 kWh Solinteg E2BA-B10K3 battery at €10,999 including VAT before support. The quoted offer was valid until 31 December 2026; confirm current availability and the scope directly.
Read the scope before comparing price per kWp
Panel power alone does not make two installations comparable. Check the exact panels and inverter, mounting system, cable routes, protection, meter, switchboard changes, transport, inspection, commissioning and connection administration. Confirm whether backup equipment and battery control are included.
Roof access, roof repairs, structural work and longer cable routes may change the final price. Ask for a site-specific price including VAT and a written list of exclusions. A 3 kWp system does not have a reliably predictable installed price obtained by scaling a 10 kWp package.
Support and financial return
The household grant described in the October 2026 source material is limited to €1,000 for PV, or €1,150 with the stated bonus, subject to eligibility and expenditure limits. Older advertised grant deductions are not proof of your entitlement.
Compare total investment with avoided imports, net export income and additional costs. Use your own confirmed support and prices in the reference calculator; its result is an illustrative scenario rather than a promised payback period.
