Low-cost, inverter-based dust monitoring method for rooftop solar
Researchers in China have developed a dust monitoring technique that relies solely on the existing hardware resources of inverters, without requiring extra sensors or meteorological data. Tests on real rooftop PV arrays demonstrated an accuracy exceeding 96%.”
New tech can tell if your EV will make it home
Researchers in California have created a new diagnostic metric that can reportedly predict if a battery can successfully power a specific task. The proposed model could be used in electric vehicles, unmanned aerial systems, and grid storage applications.
PV-powered sorption system for atmospheric water harvesting
Researchers in China have built an off-grid rapid-cycling sorption-based atmospheric water harvesting system. Powered by three PV modules, the system was tested with four condensation methods indoor and outdoor.
Vanuatu runs tender for supply, installation of solar systems
A tender is open in Vanuatu to deliver eight solar water pump systems and 24 standalone solar PV systems. The deadline to submit expressions of interest is October 27.
Japan’s Aomori prefecture sets capacity tax on large wind, solar
Japan’s Aomori prefecture is introducing a capacity-based levy on large onshore wind and solar projects, using zoning criteria to align renewable expansion with environmental, historical, and cultural priorities.
Czechia expands rules for agrivoltaics, permits vertical installations
Amendments to rules governing agrivoltaics in Czechia mean it will now be possible to deploy vertical agrivoltaics, or have installations on arable land if vegetables with high or very high labor intensity are grown at least once every three years.
Mauritania seeks consultants to support mini-grid development
A project developing green mini-grids to increase electricity access in rural Mauritania is searching for a consulting firm to support its implementation. The deadline for applications is October 17.
Solar fridges for the developing world
As climate change leads to more electricity blackouts and brownouts, the reliability of everyday refrigeration is at risk. A new IEC Standard, together with solar innovations in Africa and Asia, demonstrates how cooling can continue when power grids falter.
New research confirms rooftop PV affects urban temperatures, cooling demand
Using Lyon as a case study, an international research team has simulated the effects of rooftop photovoltaic (PV) coverage in an urban area at three levels: 25%, 60%, and 100%. The results have shown that solar panels can raise daytime temperatures by up to 0.72 °C, while cooling nighttime temperatures by up to 0.42 °C. In addition, daytime air conditioning demand has decreased by about 5%.
Ghana starts building solar for irrigation scheme
Construction is underway of a 1 MW solar project that will power agricultural production in the Greater Accra Region of Ghana. The site forms part of a Korean government-funded program addressing the twin challenges of energy transition and food security in the region.
