Scientists in Iraq used a k-Nearest Neighbors algorithm to evaluate the operational status of PV modules under various conditions, including partial shade, open circuit and short circuit scenarios. They found that the model’s overall performance in predicting wealth was “remarkably accurate.” July 23, 2024 Lior KahanaScientists from the Technical University – Iraq have used the k-Nearest Neighbors (k-NN) machine learning (ML) algorithm to classify the operational status of PV panels and predict their voltage, current and power.“At its core, k-NN works on the principle that similar things exist in close proximity. In practical terms, it can be understood that the…
CityUHK develops advanced passivator for stable perovskite solar cells City University of Hong Kong (CityUHK) recently developed an innovative passivator that significantly improves the stability and efficiency of perovskite solar cells, marking a significant advancement in solar energy technology. This new passivator, a type of corrosion inhibitor, uses dynamic covalent bonds that activate when exposed to moisture and heat, allowing it to generate new passivators in response to environmental conditions. This capability enables real-time repair and maintenance of perovskite solar cells, similar to extended-release capsules in pharmaceuticals that continuously release chemicals to heal defects caused by environmental stressors. The team’s…
As Britain awaits the outcome of the proposed Cap and Floor mechanism for long-term storage projects, the pipeline of proposed pumped hydro storage projects is gradually growing. July 25, 2024 Marija Maisch By ESS newsSSE Renewables has announced plans for a new pumped storage hydropower project at Loch Fearna in Scotland’s Great Glen, in a 50:50 development joint venture with a consortium led by UK-based hydropower project development specialist Gilkes Energy.The 1.8 GW/37 GWh Fearna Pumped Hydro Energy Storage (PHES) project has already secured a grid connection offer totaling 1,795 MW. The project aims to develop tunnels and a new…
Several factors influence the lifespan of a home battery energy storage system. We explore battery life in part 3 of our series. July 25, 2024 Ryan KennedyBy pv magazine USAIn parts 1 and 2 of this series, pv magazine assessed the productive life of residential solar panels And inverters. Here we examine home batteries, how well they perform over time and how long they last.Home energy storage has become an increasingly popular feature of home solar. a recent SunPower research of more than 1,500 households found that about 40% of Americans regularly worry about power outages. Of respondents actively considering…
Greenhouse gas reporting is the process of measuring, documenting, and disclosing emissions that contribute to climate change. This practice is crucial for identifying emission sources and tracking progress towards reduction goals. As global awareness of environmental issues grows, the importance of structured frameworks for reporting emissions becomes evident.Emerging policies and regulations are driving the need for standardized greenhouse gas reporting. These frameworks ensure that data is accurate, transparent, and comparable across different sectors. Effective reporting not only aids in regulatory compliance but also promotes informed decision-making for climate change mitigation.In this blog post, we will explore key aspects of greenhouse…
A Nexamp project currently in operation in Illinois (Source: PRNewswire) Nexamp is partnering with Starbucks, which as a long-term renewable energy buyer will anchor the deployment of 40 MW across six community solar farms in Illinois. The solar projects are expected to serve 1,100 local residents signed up within the ComEd and Ameren utility areas. Construction and operation of these projects include roles for participants in Nexamp’s fellowship programs, created through partnerships with organizations such as City Colleges of Chicago, the Chicago Urban League, Uplift Community High School, 22C and other Future Energy Jobs Act…
Martin Schachinger, the founder of pvXchange.com, explains how German solar installers are dealing with the current drop in PV module prices – now as low as €0.08 ($0.09)/kW. He says solar leasing could open up new opportunities, especially in the country’s commercial and industrial (C&I) sector. July 23, 2024 Martin Schachinger, pvXchange.comBy pv magazine GermanyModule prices have remained stable or slightly decreased this month, with no signs of change. Demand for both housing and C&I is lagging behind expectations and reaching a low not seen since the end of last year. Installers should prepare for a slow summer and consider…

With the right investment, the company can fully realize its potential and successfully open the market for roof systems,” said Solarnative’s provisional liquidator, Jan Markus Plathner from law firm Brinkmann & Partner.He sees the sale process as a good opportunity to restructure and continue the company’s activities. According to him, the first conversations…
Because the Octopus deal grew out of a smaller pilot, Bustin says Gresham House sees it as something that is possible in the broader optimization market. Image: Aura Power. Gresham House, Britain’s largest owner of battery energy storage systems (BESS), has said it believes tolling deals such as those agreed with Octopus are possible “across the optimization market”. The investment manager has a short-term target portfolio of 1,072 MW through its Gresham House Energy Storage Fund. About half of this is now part of a two-year tolling agreement with Octopus, which will pay a fixed fee and assume operations and…
SolarEdge and Kraken will enable automated sales of energy to the grid when demand is high. Image: BusinessWire Kraken, part of Octopus Energy, has joined forces with battery technology company SolarEdge to deliver flexible, automated energy savings to SolarEdge home battery users. The strategic partnership will see SolarEdge batteries integrated into the Kraken platform. This allows SolarEdge customers to charge their home battery systems with cheap, clean energy when it is most abundant and sell it back to the grid during peak times, as part of a system fully automated by Kraken. Octopus Energy customers who also use SolarEdge battery…
