How to Use This Calculator

Enter your monthly bill and city

Enter your average monthly electricity bill in Bosnian convertible marks (KM/BAM) from your utility — Elektroprivreda BiH (FBiH), Elektroprivreda RS, or Elektroprivreda HZHB (Herzeg-Bosnia). The calculator uses Bosnia's average retail rate of BAM 0.20/kWh (~€0.10/kWh). Select your city — Mostar (4.0 PSH) is the sunniest, benefiting from its southern Herzegovinian Mediterranean climate, while Zenica and Bihać (3.5 PSH) in central and northwestern Bosnia receive less sun.

Set system size and prosumer status

Select your system size in kWp. Typical Bosnian residential installs run 3–8kWp; commercial from 10kWp. Bosnia's 2024 prosumer law (enacted under FENA regulatory framework) enables residential and business customers to export surplus solar electricity to the grid and receive net metering credits at the full retail rate of BAM 0.20/kWh. If you are not yet a registered prosumer, the calculator still models self-consumption savings.

FENA prosumer and Elektroprivreda net metering

Bosnia operates a dual-entity power system. In the Federation of Bosnia and Herzegovina (FBiH), Elektroprivreda BiH is the dominant utility; in Republika Srpska, Elektroprivreda RS. Both entities now recognize prosumer status following Bosnia's harmonization with EU energy directives. Apply through your utility's grid operator (mreža operator) after system commissioning by a certified BiH electrician.

The Formula

Monthly kWh = Monthly Bill ÷ BAM 0.20/kWh (BiH retail rate) Annual production = kWp × PSH × 365 × 0.80 efficiency Self-consumption = Annual kWh × 40% (prosumer) or 55% (self-only) Self-consumption savings = Self-consumed kWh × BAM 0.20/kWh Net metering credit = Exported kWh × BAM 0.20/kWh (prosumer only) System cost = kWp × BAM 2,200–3,000/kWp (~€1,100–1,500/kWp) Payback = Total cost ÷ Annual benefit (typically 9–12 years)

Bosnia's solar economics are mid-range for the Western Balkans. The country has moderate-to-good solar resources — Mostar and southern Herzegovina rival Mediterranean levels. Electricity prices are lower than western Europe (BAM 0.20/kWh vs. €0.28/kWh in Austria) but installation costs have also fallen to competitive regional levels. The 2024 prosumer law, aligned with EU Renewable Energy Directive II, significantly improves economics by monetizing exported surplus at retail rates. No additional grid charges apply to prosumers under the current regulatory framework.

Example

Amir — Mostar villa, 8kWp prosumer

Amir owns a villa in Mostar and pays BAM 150/month for electricity. He installs an 8kWp system and registers as a FENA prosumer, enabling 1:1 net metering.

Monthly billBAM 150

City / PSHMostar, 4.0 PSH

Result

Annual production~9,344 kWh/yr

Production per kWp~1,168 kWh/kWp/yr

Self-consumption savings~BAM 748/yr

Net metering export credit~BAM 1,121/yr

Total annual benefit~BAM 1,869/yr

System cost rangeBAM 17,600 – 24,000

Payback~11.1 years

25-year net savings~BAM 25,425

Mostar's 4.0 PSH gives this system around 1,168 kWh/kWp/yr — excellent for the Balkans and rivaling Spanish levels. With prosumer net metering, the full annual production is monetized. Payback under 12 years is attractive for a Bosnian installation. Note that BAM is pegged 1:1 to the euro at a fixed rate of BAM 1.95583 = €1, so costs and savings translate directly and predictably to euro equivalents.

FAQ

Is solar worth it in Bosnia and Herzegovina? ▼

Yes, particularly in Herzegovina. Mostar (4.0 PSH) and Trebinje have solar resources rivaling southern Europe. Even Sarajevo (3.6 PSH) and Banja Luka (3.7 PSH) produce solid yields. The 2024 prosumer law enabling 1:1 net metering at BAM 0.20/kWh has significantly improved the investment case. Typical payback is 9–12 years. The BAM/euro peg eliminates currency risk for euro-denominated equipment purchases.

What is the FENA prosumer law in Bosnia? ▼

FENA (Federalna agencija za upravljanje prostorom) and the entity-level energy regulators (DERK at state level, FERK in FBiH, RERS in RS) issued prosumer regulations in 2024, aligned with EU REDII. Prosumers (proizvođači-potrošači) can install solar systems and export surplus to the grid, receiving credits at the full retail rate — BAM 0.20/kWh — under a virtual net metering scheme. The excess credit carries over monthly and settles annually. Systems up to 500kW are eligible.

Which city gets the most solar in Bosnia? ▼

Mostar (4.0 PSH) is Bosnia's sunniest major city, located in the dry karst landscape of Herzegovina with a sub-Mediterranean climate. Trebinje in southern Herzegovina receives similar or even more sun but is a smaller city. Banja Luka (3.7 PSH) in northern Republika Srpska benefits from the flatter Pannonian influence. Sarajevo (3.6 PSH) sits in a valley with some shading from surrounding mountains and occasional thermal inversions that reduce insolation.

How much does solar cost in Bosnia? ▼

Solar system costs in Bosnia run approximately BAM 2,200–3,000/kWp (~€1,100–1,500/kWp) for a fully installed system including panels, inverter, mounting, and wiring. A typical 5kWp residential system costs BAM 11,000–15,000. Prices have fallen 30–40% since 2020 due to cheaper Chinese panel supply. Most installers accept payment in BAM; since the marka is pegged to the euro at 1.95583, euro pricing from German or Italian suppliers translates directly. VAT in BiH is 17%.

Does Bosnia have a feed-in tariff for solar? ▼

Bosnia does not currently have a widespread residential feed-in tariff (FiT) in the German/Austrian sense. The prosumer net metering scheme (2024) effectively delivers BAM 0.20/kWh for exported surplus — equivalent to the avoided retail cost — which is the standard EU model for small prosumers. Larger commercial and utility-scale solar projects (above 500kW) may access competitive auction tariffs under Bosnia's renewable energy development plans for EU accession. Bosnia is an EU candidate country as of 2022.
