Czech automotive facility navigates energy volatility with a 648 kWp rooftop solar plant to secure operational efficiency

At the Hyundaimanufacturing complex in Nošovice, Czech Republic, a new 648 kWp rooftopphotovoltaic plant is now operational, transforming an industrial roof into ahigh-yield energy asset. Carefully designed by a local installer in cooperationwith LONGi’s certified partner, Memodo, the project reflects a growingimperative across the Central European industrial landscape: mitigatingexposure to grid volatility by generating reliable, decentralized clean energy.

Energy costpredictability drives new investments in commercial rooftops

For the CzechRepublic, an economy heavily driven by its robust automotive and manufacturingsectors, energy cost predictability is a cornerstone of competitiveness.Following recent years of severe electricity price fluctuations across Europe,industrial facilities face immense pressure to optimize their operationalexpenditures (OPEX).

For large-scalemanufacturing sites like the Hyundai complex, where operations consume vastamounts of power, transitioning to on-site solar is no longer merely anenvironmental target. It functions as a critical economic shield designed tosignificantly reduce routine energy expenses, safeguard profit margins, and supportlong-term business continuity.

HPBC 2.0technology overcomes regional summer heat and winter overcast

Maximizing theavailable flat roof at the Nošovice complex required an East-West mountingconfiguration. While this layout increases panel density, it typically trapssummer heat, leading to thermal degradation and output losses in conventionalmodules.

LONGi’s HPBC 2.0(Hybrid Passivated Back Contact) technology directly counters this thermalchallenge. “Our 2nd-generation Back Contact technology allows modules tooperate up to 3°C cooler, delivering up to 8% higher overall performance inthese constrained configurations,” noted Mr. Čelovský from LONGi.

But managingsummer heat is only half the operational reality. Czechia is characterized bymoderate to heavy cloud cover and lower solar irradiance during the long wintermonths. These conditions can pose severe challenges for conventional solarmodules.

With afront-side busbar-free design, LONGi’s modules capture more light, whichtechnical specifications indicate results in 2.27 percent higher efficiencythan conventional TOPCon solutions and up to 18 percent better output inlow-light conditions. This is an ideal feature for the Czech climate, definedby variable sunlight and seasonal shifts, where solar systems must beengineered for consistent, reliable output throughout the entire year.

Optimized designreduces BOS and labor costs by up to 14%

Beyondall-season energy yield, the choice of LONGi Hi-MO X10 modules directlyimpacted the project's installation economics. Thanks to their higherefficiency and optimized footprint, the team was able to reach the 648 kWpcapacity target using significantly fewer individual panels.

This streamlinedapproach translated directly into measurable balance of system (BOS) savings.By handling fewer modules, the project achieved a 10% reduction in mountingstructure costs and up to a 14% saving in installation labor time.Logistically, it saved the equivalent of seven pallets of material, drasticallyreducing rooftop transport constraints and accelerating the project completiontimeline.

The Nošoviceinstallation serves as a practical blueprint for industrial resilience

The 648 kWpinstallation at the Nošovice complex stands as a clear reference point for thewider manufacturing sector. By combining advanced, climate-optimized PVtechnology with strong local partnerships, the project demonstrates howindustrial facilities can effectively optimize rooftop space, lower upfrontcapital costs, and neutralize external energy risks. It proves that for today'sCEE businesses, energy independence is a highly achievable and financiallysound reality.
