A major investment, currently in the permitting process, consists of the construction of the largest battery storage facility in Slovakia and a photovoltaic power plant with a planned capacity of 30 MW. The plant is expected to have 54,000 double-sided photovoltaic panels.
Slovak Solar s.r.o. is a leading photovoltaic wholesaler in Slovakia, Czech Republic and Austria, with a vision to create a sustainable energy future. We started our journey in 2009 with the main idea – to provide companies specialised in the installation of solar systems with access to first-class photovoltaic products, all from one place.
At Slovak Solar, we believe that progress comes from constant innovation. From day one, we’ve been breaking new ground in Slovakia’s solar energy sector. We were one of the first company in Slovakia to install Building-Integrated Photovoltaics (BIPV).
Nuclear power plants are the main source of electricity production in Slovakia. In 2022, over 59 percent of total electricity generation in the country was derived from this source. By comparison, hydroelectric power plants accounted for 13.7 percent of power production, the most of any renewable source.
Primary energy use in Slovakia was 194 TWh and 36 TWh per million inhabitants in 2009. Slovakia has a plan to get renewable sources of energy up to 19.2% by 2030. From 2024, following the completion of two new nuclear reactors, Slovakia will return to being a net exporter of electricity. Slovnaft is the largest oil refinery in Slovakia.
The electricity price for businesses is EUR 0.253 kWh or USD 0.291. These retail prices were collected in September 2024 and include the cost of power, distribution and transmission, and all taxes and fees. Compare Slovakia with 150 other countries.

The global residential solar storage and inverter market is experiencing rapid expansion, with demand increasing by over 300% in the past three years. Home energy storage solutions now account for approximately 35% of all new residential solar installations worldwide. North America leads with 38% market share, driven by homeowner energy independence goals and federal tax credits that reduce total system costs by 26-30%. Europe follows with 32% market share, where standardized home storage designs have cut installation timelines by 55% compared to custom solutions. Asia-Pacific represents the fastest-growing region at 45% CAGR, with manufacturing innovations reducing system prices by 18% annually. Emerging markets are adopting residential storage for backup power and energy cost reduction, with typical payback periods of 4-7 years. Modern home installations now feature integrated systems with 10-30kWh capacity at costs below $700/kWh for complete residential energy solutions.
Technological advancements are dramatically improving home solar storage and inverter performance while reducing costs. Next-generation battery management systems maintain optimal performance with 40% less energy loss, extending battery lifespan to 15+ years. Standardized plug-and-play designs have reduced installation costs from $1,200/kW to $650/kW since 2022. Smart integration features now allow home systems to operate as virtual power plants, increasing homeowner savings by 35% through time-of-use optimization and grid services. Safety innovations including multi-stage protection and thermal management systems have reduced insurance premiums by 25% for solar storage installations. New modular designs enable capacity expansion through simple battery additions at just $600/kWh for incremental storage. These innovations have improved ROI significantly, with residential projects typically achieving payback in 5-8 years depending on local electricity rates and incentive programs. Recent pricing trends show standard home systems (5-10kWh) starting at $8,000 and premium systems (15-20kWh) from $12,000, with financing options available for homeowners.
