The lack of a transparent grid capacity system in Czechia is eroding the solar self-consumption business model, and in some parts of the country, grid bottlenecks are delaying grid connections.

CNPC and Sinopec are working on transporting hydrogen via pipelines, while Matrix Renewables has expanded its green hydrogen partnership with Rolwind Renovables.

Romania-based startup Photovoltaic Windows has developed an off-grid domestic hot water system powered by cadmium telluride (CdTe) photovoltaic semi-transparent glasses. It claims a 0.7 kW pilot installation on an apartment balcony in Bucharest resulted in annual savings of €1,100 ($1,202).

The 9.9 MW DeLasol PV project is located in the municipality of Lapovo, central Serbia.

Daikin has started building its first heat pump factory in Lodz, Poland. The Japanese heating manufacturer will invest €300 million ($327.2 million) in the new facility, which is expected to start operations in July 2024.

Hungary’s Platio has inaugurated a solar footpath in the Dutch city of Groningen. The installation consists of 2,544 monocrystalline Patio solar pavers with a 21.8% efficiency rating. It will generate 55,000 kWh of electricity per year and can purportedly withstand a pressure of 2 tons without microcracks.

Storage specialist Fluence has launched Ultrastack, a battery energy storage system (BESS) for storage-as-transmission assets (SATA). It is designed to help network owners and operators to manage renewables curtailment, increase the use of power lines, and limit congestion.

While it initially had a chilling effect on the Polish residential solar market, the transition from net metering to net billing has also resulted in positive changes, such as better sizing of rooftop PV systems and a higher rate of self-consumption, says Instytut Energetyki Odnawialnej (IEO), a Polish research body.

The Czech Republic is pouring an additional CZK 55 billion ($2.5 billion) into its New Green Savings program, which includes rooftop PV rebates, among other energy-saving measures in the residential sector.

Poland emerged as Europe’s third-biggest solar market in 2022, driven by the rapid uptake of PV micro-installations below 50 kW in size, but this year is already starting to look different. Marcin Ślęzak, chief commercial officer of Warsaw-based Menlo Electric, recently spoke to pv magazine about changes on the demand side and tech preferences in this thriving market.
