The use of polymer electrolyte membrane fuel cells as backup power generation in solar microgrids could drive down costs and improve efficiency, according to an international group of researchers. They have proposed a new energy management system that could be ideal for hybrid solar-hydrogen microgrids in remote locations.

In an interview with pv magazine, Indra Overland, head of the Center for Energy Research at the Norwegian Institute for International Affairs, explains how international hydrogen strategies may play out in the upcoming decades. Plans and roadmaps will not be enough to turn a hydrogen economy into reality and its success will depend on becoming cost-competitive vis-à-vis other solutions in several areas, he says.

Australian scientists have demonstrated two loss-mitigation techniques that could improve solar‐to‐hydrogen (STH) conversion efficiencies and may lay the ground for cheaper PV-powered hydrogen generation. By combining the two techniques, they were able to achieve an STH efficiency of around 19.4% at realistic operating temperatures.

Solar Philippines is planning to deploy several unsubsidised solar plants in the provinces of Batangas, Cavite, Nueva Ecija, and Tarlac.

Scientists in the Netherlands are planning to build intelligent PV devices for energy and information applications. Their intention is to make this approach a new field of PV research, whose ultimate goal is enabling solar cells to communicate with each other and with other devices, ensuring that all the generated energy ends up exactly where it’s needed, especially in the urban environment.

Researchers in New Zealand have developed a new methodology for solar park planning that considers clear-sky radiation for voltage stability analysis. It is based on two different generation profiles for separate purposes.

South Korean manufacturer Clenergy has unveiled a new mounting solution for PV panels installed in balconies. The structure is adjustable to different types of commonly-sized balconies with metal railings.

A group of German scientists has analyzed the possible trajectory of carbon nanotubes (CNTs) in photovoltaic research and industry and has suggested a roadmap to bring this technology closer to mass production. Despite a large number of challenges, the academics predicted a brilliant future for CNTs in PV applications, explaining that the barriers to their adoption are constantly being reduced.

A Dutch-Hungarian research team has measured, for 12 years, the degradation rates of PV modules installed in an off-grid system located in Ghana. It found that the panels had an average annual decline in power yield of 3.19%.

South African scientists have used a PV system to keep tomatoes in cold storage. They linked an air-cooling system and evaporative cooling tech to a 3.5 kW array and 12 batteries and tested it for 28 days in September.
