1,2 MWp u jednoj sezoni: postavljanje sustava Adriatic Hotels Group 1.2 MWp in one season: deploying Adriatic Hotels Group
Najveći pojedinačni projekt koji smo realizirali u 2025. godini bila je instalacija 1,2 MWp solarnih sustava na pet hotela Adriatic Hotels Group raspoređenih duž jadranske obale. Projekt je bio logistički izazov visokog reda — ali i potvrda da je masovni rollout solarnih sustava u hotelijerstvu moguć unutar jedne sezone.
Pet hotela, pet izazova
Projekt je obuhvaćao pet objekata: dva hotela u Splitu (250 soba, ravni betonski krovovi), jedan u Omiš-Rivijeri (120 soba, kosi crijepni krov), jedan u Hvaru (80 soba, kombinacija krovova s pogledno zaštićenim područjem) i jedan na Braču (180 soba, šatorasti krov hotela). Svaki objekt bio je zaseban projekt sa zasebnom elektroprojektnom dokumentacijom.
Specifičan izazov bio je Hotel Hvar — Hvar je pod konzervatorskim zahtjevima za vizure i krovne profile, pa je dokumentacija za lokacijsku dozvolu trajala 3 tjedna duže od standarda. Rješenje su bili paneli smanjene vidljivosti (all-black Longi Hi-MO 6) montirani u horizontalnom položaju bez izlaska iznad krovne linije, uz posebno mišljenje Konzervatorskog odjela MKKM-a.
Logistika: 3.000 panela za 24 tjedna
Projekt je trajao od travnja do rujna 2025. — 24 radna tjedna s timom od 24 tehničara raspoređenih na 3-5 lokacija simultano. Ukupno je montirano 2.970 panela (mix Longi i Jinko 405-440 Wp), 12 Huawei trofaznih invertera (SUN2000-100KTL za veće i SUN2000-36KTL za manje hotele) i kompletna kabelska infrastruktura.
Koordinacija nabave bila je kritična: paneli su dolazili u tri shipment-a iz Hamburga (DVS ruta), svaki 1.000-1.200 komada. Kašnjenje jednog shipment-a za 8 dana u srpnju umalo je ugrozilo rok završetka Hotela Split-2 — mobilizirali smo dodatnu ekipu od 6 tehničara iz Rijeke kako bismo nadoknadili zaostatak.
„Jednom kad imate iskustvo s 5+ hotelskih projekata istovremeno, shvatite da je logistika važnija od tehnike. Paneli su standardni — raspored timova, transport i priključni rokovi su pravi posao."
Financijski rezultati: 154.000 € godišnje
Prema projektnim procjenama verificiranim prvih šest tjedana produkcije, pet hotela zajedno generirat će oko 1,1 GWh godišnje. Pri prosječnoj poslovnoj tarifi od ~0,140 €/kWh (hoteli imaju povoljnije tarife od kućanstava), godišnja ušteda iznosi ~154.000 €. Ukupna investicija iznosila je 1.240.000 € — što daje ROI od 8,0 godina. Za usporedbu, prosječni hoteli u Hrvatskoj troše 40-60% električne energije za klimatizaciju u ljetnim mjesecima — upravo kada je solarna produkcija najveća, a potrošnja klime najviša.
ESG i certifikacijski benefit
Pored financijskih ušteda, Adriatic Hotels Group sada može koristiti solarne kapacitete u ESG izvještavanju i pri aplikacijama za EU fondove za turizam (NPOO). Smanjenje CO2 emisija od 550 tona/godišnje (pri emisijskom faktoru HROTE: 0,5 kgCO2/kWh) otvorilo je put za prijavu na EHOTELI program koji sufinancira energetske obnove ugostiteljskih objekata.
The largest single project we completed in 2025 was the installation of 1.2 MWp of solar systems on five Adriatic Hotels Group properties along the Adriatic coast. The project was a high-level logistics challenge — but also confirmation that mass solar deployment in hospitality is achievable within a single season.
Five hotels, five challenges
The project covered five properties: two hotels in Split (250 rooms, flat concrete roofs), one on the Omiš Riviera (120 rooms, pitched tiled roof), one in Hvar (80 rooms, combination roof in a viewshed-protected area), and one on Brač (180 rooms, hipped hotel roof). Each property was a separate project with separate electrical engineering documentation.
A specific challenge was the Hvar Hotel — Hvar has conservation requirements for views and roof profiles, so documentation for the location permit took 3 weeks longer than standard. The solution was low-visibility panels (all-black Longi Hi-MO 6) mounted horizontally without projecting above the roofline, with a special opinion from the Conservation Department of MKKM.
Logistics: 3,000 panels in 24 weeks
The project ran from April to September 2025 — 24 working weeks with a team of 24 technicians deployed at 3-5 locations simultaneously. In total, 2,970 panels (mix of Longi and Jinko 405-440 Wp), 12 Huawei three-phase inverters (SUN2000-100KTL for larger and SUN2000-36KTL for smaller hotels), and complete cabling infrastructure were installed.
Supply coordination was critical: panels arrived in three shipments from Hamburg (DVS route), each 1,000-1,200 units. An 8-day delay of one shipment in July nearly jeopardised the completion deadline for Hotel Split-2 — we mobilised an additional team of 6 technicians from Rijeka to make up the shortfall.
"Once you have experience with 5+ hotel projects simultaneously, you realise that logistics matters more than technology. Panels are standard — team scheduling, transport, and connection deadlines are the real work."
Financial results: €154,000 annually
According to project estimates verified in the first six weeks of production, the five hotels together will generate around 1.1 GWh annually. At the average commercial tariff of ~€0.140/kWh (hotels get better rates than households), annual savings amount to ~€154,000. Total investment was €1,240,000 — giving an ROI of 8.0 years. For comparison, the average Croatian hotel spends 40-60% of its electricity on air conditioning in summer months — precisely when solar production is highest and AC consumption peaks.
ESG and certification benefits
Beyond financial savings, Adriatic Hotels Group can now use the solar capacity in ESG reporting and when applying for EU tourism funds (NPOO). A CO2 reduction of 550 tonnes/year (at the HROTE emission factor of 0.5 kgCO2/kWh) opened the way for an application to the EHOTELI programme co-financing energy renovations of hospitality businesses.
