Following reports of fraudulent solar inspections, Poland’s energy regulator has issued an announcement clarifying who is authorized to conduct such assessments. 

Poland’s lower house of parliament, the Sejm, has passed amendments to the Building Law to remove the requirement for building permits to construct energy storage facilities with capacities of up to 30 kWh.

Tests conducted by a research team in outdoor environments in Spain and Poland have demonstrated a strong correlation between perovskite solar cell degradation and the combined effects of climatic and operating conditions. The scientists found that open-circuit operation accelerates degradation, whereas operation at the maximum power point and under short-circuit conditions has a lower impact.

A four-year analysis conducted at a testing field in eastern Poland has shown that crystalline solar panels offer a stronger performance than thin-film panels at high latitudes. The tests revealed pronounced seasonal variability across all technologies, with thin-film modules showing markedly lower capacity factors than crystalline silicon, particularly in winter.

The budget for the sixth round of Poland’s rebate scheme for residential solar and storage installations was extended to a record PLN 1.85 billion ($511.8 million), up from an original PLN 400 million, after receiving 121,000 applications. Over half of the budget will be allocated to home energy storage facilities.

Qatari researchers tell pv magazine that they have designed the world’s first hybrid station concept combining PV, liquid air, hydrogen storage, and batteries for EV charging and hydrogen refueling.

Researchers have collected data from solar sensor-equipped vehicles, racking up over a million km mainly in the Benelux and German region, to be able to make more accurate efficiency and yield predictions. The research project is part of an ongoing three-year European assessment of VIPV.

Czechia, Hungary, Poland and Slovakia’s cumulative solar generation increased sixfold between 2019 and 2024, while each country made efforts to reduce its coal dependency. However, energy think tank Ember says a lack of battery storage uptake and solar targets below the EU average risk derailing progress.

New research from Poland has suggested installing 891 PV panels along the entire tram platform and inter-track spaces of four major transportation hubs. The analysis showed that the PV system could power all of the city’s tram stops, the passenger information system, and meet 10% of demand from service depots.

PGE Group has launched a tender for a 400 MW/2-hour battery energy storage system in Gryfino, Poland, expanding the state-owned company’s national storage capacity to 800 MWh.
