The new Power Control System (PCS) is designed to maximize capacity and storage integration with solar panels. September 26, 2024 Ryan KennedyChinese power electronics supplier APsystems has announced the release of a new power control system (PCS). The new model, ELS 11.4k PCS, offers higher rated and peak power over previous models.The PCS also adds a generator connectivity feature, allowing the homeowner to integrate generators to operate alongside their home solar and energy storage systems.The PCS provides rated power up to 11,400 VA and peak backup power up to 17,100 VA for 10 seconds. This allows the device to support…

Energy Toolbase and Stellar Solar have implemented an advanced energy management system for the Mira Loma transportation campus. September 26, 2024 Ryan KennedyBy pv magazine USAEnergy Toolbase and San Diego-based solar installer Stellar Solar Commercial have collaborated to deliver a solar and energy storage project for a transportation campus operated by Marten Transport in Mira Loma, California. The project included two solar carport structures with a capacity of 197 kW. Stellar Solar also installed a 60 kW / 266 kWh BYD Chess energy storage system. The four-hour battery life is managed by Acumen EMS control software. The primary control application…

AleaSoft Energy Forecasting says most major European markets recorded higher electricity prices last week due to lower solar and wind energy production and despite a decline in gas and CO2 prices. September 25, 2024 Patrick JowettMost major European markets recorded an increase in average electricity prices last week, according to an analysis by AleaSoft Energy Forecasting.Compared to the previous week, average prices rose in the British, German, Italian, Scandinavian, Portuguese and Spanish markets, but fell in the Belgian, Dutch and French markets.Weekly averages were below €81/MWh in all markets last week, except the UK and Italian, where averages of €95.81/MWh…

Artemis of Monalee Solar energy sales company Monalee is now making its proprietary software available to other solar energy companies. Artemis by Monalee is designed for agile solar companies looking to reach new audiences, grow revenue and expand their offerings. Using Artemis technology, companies can now create personalized solar proposals in less than 15 seconds, scale without overhead and increase customer satisfaction. Unlike buying a car or a house, prices for purchasing solar power are not readily available on 99% of solar company sites. Potential customers must wait at least 15 minutes (up to several days) before receiving a solar…

Scientists in Spain have developed a semi-online technique to predict solar radiation at different locations in a photovoltaic installation. The proposed training approach is described as suitable for predicting highly variable time series. September 25, 2024 Lior KahanaResearchers from the University of Seville in Spain have developed a new machine learning algorithm for predicting very short-term solar radiation. The input is based on sensor data preprocessing using temporal and spatial correlation analysis of cloud movements.“Short- or very short-term forecasts of electricity production can help in areas such as real-time monitoring of the system, electricity prices or avoiding system overloads,” they…

CS energy And Luminance have completed two 5 MW landfill solar projects in Berkeley, New Jersey. These co-located projects are among the first ever to simultaneously close a landfill and build a solar system on top of the landfill. Including these projects, CS Energy has now completed more than 230 MW of landfill solar projects in the United States. These projects are expected to deliver more affordable clean energy to 1,800 homes, more than half of which will be low-to-moderate income (LMI) households. In total, these community landfill solar projects are expected to save participants approximately $6.4 million over the…

Research shows that the efficiency of hot-carrier solar cells has improved Hot-carrier solar cells, first proposed decades ago, have been a major focus in surpassing the Shockley-Quisser efficiency limit in single-junction solar cells. Despite their theoretical advantages, these cells have faced significant challenges, especially in rapidly extracting hot electrons across material interfaces. Recent studies have explored the use of satellite valleys in the conduction band to temporarily store hot electrons before extraction. However, a parasitic barrier at the interface between the absorber and extraction layers has posed a major obstacle. This barrier complicates electron transfer, which takes place in real…

The German research institute said it used a hybrid production route to apply the perovskite solar energy to the top PV device of the cell, based on an industrial textured silicon heterojunction technology. A standard silicon solar cell was used for the bottom subcell. September 25, 2024 Emiliano Bellini Germany’s Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE) announced today that it has achieved an energy conversion efficiency of 31.6% for a perovskite-silicon tandem solar cell.The result was confirmed by the CalLab calibration laboratory of Fraunhofer ISE.The researchers explained that that cell consists of a top perovskite PV device based…

The Italian manufacturer said its new multipurpose reversible heat pump has a seasonal coefficient of performance of 4.44 to 4.59 and a seasonal energy efficiency ratio of 7.72 to 7.53. It is said that it can reach a supply temperature of up to 55 °C. September 25, 2024 Emiliano BelliniItalian heat pump manufacturer Clivet has unveiled a multi-purpose reversible heat pump for industrial applications.The new product, called SCREWLINE-i (WiDHN-KSL1 PL), uses a hydrofluorolefin-based, azeotropic refrigerant known as R513a and inverter screw compressors.“Our new water-cooled multifunctional heat pump is innovative and quiet,” said company product manager Marco Zanin. pv magazine. “It…

Saipem, an Italian oilfield service provider, has developed a floating offshore PV platform in collaboration with its Norwegian unit Moss Maritime. September 25, 2024 Sergio MatalucciBy pv magazine ItalyItalian gas contractor Saipem has deployed a new offshore floating solar panel near the island of Froya in the Norwegian Sea, near Trondheim.Saipem’s Moss Maritime unit developed the XolarSurf prototype with Norway-based Kystteknikk Maritime Service AS. The system is built to withstand waves up to 8 meters high.“These waves can be found, for example, in much of Southeast Asia, the coastal areas of the Mediterranean, the Gulf of Guinea or the Middle…
