Researchers from Spain have developed a method to estimate the critical speed that a tracker can withstand. They found “good agreement” when comparing the model with experimental results. December 13, 2023 Lior KahanaResearchers from the Technical University of Madrid in Spain have introduced a new way to calculate the effective damping coefficient of single-axis solar trackers. In aerodynamics, damping is the force opposing the motion of a vibrating or oscillating system, and its effective coefficient is a parameter related to its stability.The proposed approach allows developers to estimate the critical speed that a tracker can withstand.“We do not rule out…
September ushers in gorgeous fall colors in Colorado Springs, but that doesn’t mean the time to harness the sun’s power is fading away. Solarise Solar, Colorado’s premier solar panel company, continues to help homeowners effectively install and maintain solar panels for optimal performance.
The development of the carbon credit market is considered a concrete step towards policies to reduce greenhouse gas emissions, allocate emission quotas, trade carbon credits and create green finance for Vietnam. Nguyễn Văn Duẩn, deputy director of Quảng Bình Province’s Forest Protection Department, said the province would not only leverage the strengths of natural forests, but also expand its scope, evaluate eligible areas and reduce the potential for of greenhouse gas emissions by implementing new forest plantation activities. according to international standards, converting small timber plantations into larger ones to increase forest carbon reserves in the future. The province would…
Lightsource bp says it plans to develop a solar-plus-storage facility in Ireland. The proposed installation will consist of a 57 MW solar array and a 54 MW energy storage system on an open grassland site in the eastern part of the country. May 10, 2024 Patrick JowettLight source bp has outlined a proposal for the financing, development and construction of a 57 MW solar and 54 MW energy storage facility near Kells, County Meath, Eastern Ireland. The proposed solar installation will generate enough renewable energy to power 21,300 homes, the company said.The facility will be built on open grassland on…
SolarPower Europe has published floating solar guidelines to provide an overview of the European market and global landscape, with practical advice for project developers.

When designing a solar system, you must select solar energy equipment that best meets the needs of your customers. Many potential customers may have questions about alternating current (AC) and direct current (DC), charge controllers, power inverters and solar power converters. These are crucial topics that installers need to understand and explain so that the customer can make an informed purchasing decision. AC vs. DC power supplyElectricity exists in two forms: AC and DC current. The terms describe the direction of electric current in a circuit. With DC voltage, the current flows in one direction. For alternating current, electrons change…
Steve Newby Solar energy radiation and Pivot Energy have collaborated on a portfolio of five community solar projects in Illinois with a combined capacity of 19 MW, all of which will be completed this year. The portfolio is estimated to produce enough power to power 3,800 homes annually, the company says. Atlanta-based Radiance Solar serves as an EPC partner and has completed more than ten community solar projects in Illinois. Denver-based Pivot Energy owns the facilities. “Our partnership with Pivot Energy on this portfolio reinforces our long-standing commitment to the renewable energy sector in Illinois,…
Optimizing grid integration for California’s energy future On May 1, 2024, the California Public Utilities Commission (CPUC) hosted the third workshop of the High DER Future Grid Study, bringing together stakeholders and experts virtually to develop solutions for improving grid operations with a large volume of distributed energy resources (DERs) . . The workshop aimed to align California’s electric grid modernization initiatives with climate and equity goals. Workshop Insights and objectives Facilitated by Gridworks, this session of the CPUC’s Amended Scoping Memo in Rulemaking R.21-06-017 explored operational needs essential to an efficient high DER network. Topics of discussion included enabling…
In a new weekly update for pv magazineOPIS, a Dow Jones company, provides a brief overview of the major price trends in the global PV industry. May 10, 2024 OPISThe Chinese Module Marker (CMM), OPIS benchmark rating for TOPCon modules from China, and mono-PERC module prices remained stable at $0.115 per W and $0.105/W, respectively.Market activity in the Chinese market has yet to pick up, although Chinese solar companies have returned after the Labor holidays. Trading remained subdued with few buyers in the market and these buyers were mainly bargain hunting, a market source said.Demand remained weak as upstream prices…
Researchers in India have developed a new solar panel recycling process that converts lead into less toxic lead monoxide. It consists of three main steps: leaching, precipitation and calcination. May 7, 2024 Emiliano BelliniResearchers from India’s Center for Materials for Electronics Technology (C-MET) have developed a new process to recover lead (Pb) from photovoltaic panels at the end of their life.“The lead recovery process outlined in our study offers a new and environmentally conscious approach to recycling waste silicon photovoltaic modules,” said the study’s lead author, Duvvuri S. Prasad, narrated pv magazine. “Unlike traditional methods that focus on recovering valuable…
