The…
Alight and 3Flash have signed a joint development agreement for a 120 MW solar project in southeastern Finland. Work is expected to start early next year and commissioning is scheduled for 2027. October 21, 2024 Patrick Jowett Image: Mariana Proenca, Unsplash Sweden’s Alight and Finland’s 3Flash have entered into a joint development agreement for the construction of a 120 MW solar park in Loviisa, a city in the southeast of Finland. Construction is expected to begin early next year and commissioning is currently scheduled for 2027. Once completed, it is expected to generate 155 GWh, equivalent to the annual electricity…
NESO said it is committed to a “level playing field” for all technologies in the market. Image: National Network. The UK National Energy System Operator (NESO) has set out four “short-term” actions to have a “meaningful impact” on the skip rate, in response to an open letter from the Battery Storage Coalition. NESO has convened the roundtable of energy industry leaders representing battery owners, developers and investors to demonstrate its commitment to transparency and collaboration. First, it will release an updated dispatch algorithm in the control room, promising that “critical” new assets will start in the control room from early…
The Chinese manufacturer said its new series includes inverters with AC power up to 15 kW. It supports a maximum input current of 20A. October 21, 2024 Lior Kahana Chinese inverter supplier Solis has released a new series of three-phase hybrid low-voltage inverters. The new S6-EH3P(8-15)K02-NV-YD-L series includes inverters with an AC power of 8 kW, 10 kW, 12 kW or 15 kW. “A major advantage of using a low-voltage PV inverter is the ability to combine it with much cheaper low-voltage batteries,” a company spokesperson told PV Magazine. “The price gap between low and high voltage batteries is widening,…
Nigel Pocklington, CEO of Good Energy (pictured), says the service will provide fairness to FIT microgenerators. Image: Good energy. Renewable energy supplier Good Energy has unveiled a new service for electricity generators with feed-in tariffs (FIT) to register them for the Renewable Energy Guarantees of Origin (REGO) scheme. The REGO program is designed to provide consumers with clear information about the share of energy suppliers source from renewable energy sources, while also allowing companies to demonstrate their green energy purchasing when reporting their emissions. However, FIT microgenerators – the usual owners of small solar installations – have historically been excluded…
After years of conducting theoretical studies on gallium phosphide and titanium solar cells, a group of Spanish researchers have now attempted to build the first mid-band device based on this material combination and found that it can achieve improved external quantum efficiency at wavelengths above 550 nm. October 21, 2024 Emiliano Bellini A group of scientists led by the Universidad Complutense de Madrid in Spain has for the first time produced an intermediate band (IB) solar cell based on gallium phosphide (Gap) and titanium (Ti). It is believed that the IB solar cells have the potential to… Shockley-Queisser limit –…
Researchers from Poland have investigated how textured glass used as the front of building-integrated photovoltaic panels affects performance. They have found that energy yield can be up to 5% lower compared to conventional glass-based modules, with reflection parameters up to 88% in the visible area. October 21, 2024 Lior Kahana Scientists from Poland’s John Paul II Catholic University of Lublin have analyzed the optical and electrical parameters of textured glass in integrated photovoltaic (BIPV) systems and found that this type of glass can significantly influence PV energy generation and increase light reflection. “In the case of installations in urban spaces,…
Martin Schachinger, the founder of pvXchange.com, reports that prices of tunnel oxide passivated contact (TOPCon) solar panels in Germany have fallen by an average of €0.010 ($0.0109)/W this month. Demand remains particularly weak in the residential sector, while complex authorization processes also pose a challenge for the commercial and industrial (C&I) and land-based segments. October 21, 2024 MARTIN SCHACHINGER, PVXCHANGE.com By pv magazine Germany Germany’s PV industry is struggling, with company bankruptcies piling up, reflecting a trend seen across all sectors. According to Deutsche WirtschaftsnachrichtenBankruptcies reached a peak not seen since 2010 in the third quarter of 2024, mainly due…
The Nepal Electricity Authority (NEA) has received proposals from 134 companies for a total of 3.6 GW. It says 259 projects from 127 developers have passed the technical bid evaluation and will be considered when financial proposals open on October 22. October 18, 2024 Patrick Jowett Image: Samrat Khadka, Unsplash The proposals received to develop 800 MW of grid-connected solar power in Nepal equate to more than four times the available capacity under the tender, according to new figures from the NEA. The state-owned company conducted the tender earlier this year. It says it has received proposals from a total…
Chinese EV battery giant CATL reports that profits have increased Chinese battery giant CATL reported a 26.0 percent profit increase in the third quarter on Friday, but still fell short of analyst expectations. Founded in 2011 in the Chinese east coast city of Ningde, CATL produces more than a third of the EV batteries sold worldwide. They are used in models from a long line of foreign manufacturers, including Mercedes-Benz, BMW, Volkswagen, Toyota, Honda and Hyundai. A drop in the cost of raw materials used to make batteries has caused a price war among industry players, weighing on sales. In…
