The effects of solar module elevation on ground-mounted PV
Scientists in Hungary found that ground-mounted PV modules at an intermediate elevation of 1.1 m achieve the highest efficiency and power output due to improved airflow and reduced cell temperature. Their study also estimated a levelized cost of electricity of $0.0843/kWh and 577.78 kg CO₂ mitigation over 25 years, while noting results are specific to concrete surfaces.
North Macedonia adds 210 MW of solar in 2025
North Macedonia’s cumulative solar capacity passed the 1 GW milestone in 2025, with the market currently led by utility-scale and C&I installations. Looking ahead, all market segments are anticipated to move towards hybrid solar-plus-storage solutions following the introduction of a new energy law last year.
Slovenia adds 146.5 MW of solar in 2025
Slovenia installed less solar in 2025 than in 2024, largely down to a sharp drop in residential installations. The country’s cumulative solar capacity now stands at 1.57 GW.
The prospects for ultra-high-temperature heat pumps
An international research team has reviewed emerging solid-state and gas-cycle heat pumps capable of reaching temperatures of up to 1,600 K, assessing their challenges, applications, scalability, and technology readiness levels. The researchers say these systems could outperform conventional high-temperature heating technologies by achieving coefficients of performance above 1.
Hinen launches 15 kW three-phase hybrid inverter
The Chinese manufacturer said its 15 kW three-phase low-voltage hybrid inverter is paired with the stackable BP5000 5 kWh battery supporting up to 120 kWh. It features three MPPTs, 150% oversized PV input, and smart load management for optimized self-consumption.
Hungary launches grants for residential battery storage
Hungary has opened applications for a program offering up to HUF 2.5 million ($7,820) per household to support residential battery storage, prioritizing grid-exporting solar users and small rural settlements.
Work begins on Georgia’s first utility-scale solar plant for on-site consumption
The First Light project is billed as the first industrial-scale solar power plant built entirely for self-consumption in the South Caucasus region.
Latvia’s largest single-site solar plant begins operating
The 120.8 MW project, built by Lithuanian renewables developer Green Genius, is the largest single-site project in the Baltics. Work is currently underway on constructing a 50 MW/100 MWh battery energy storage system on-site.
Made in Europe: Sungrow builds first European factory in Poland
Sungrow says it plans to invest €230 million ($274 million) in its first European factory in Wałbrzych, Poland, to produce inverters and battery energy storage systems (BESS).
Armenia adds around 615 MW of solar in 2025
Armenia enjoyed a record year for solar deployment last year, surpassing 1 GW of cumulative solar capacity. The market is currently led by autonomous solar producers, of which there are now more than 50,000 in the country.
