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.
An international research team has analyzed all existing cooling technologies for PV panels and has indicated the current best options and future trends of research. According to its findings, active water cooling, although expensive and not particularly practical, is the most effective cooling technique while passive cooling systems, despite being easy to apply, have still limited possibilities.
The 13 MW array was deployed in the Selangor state on the west coast of Peninsular Malaysia. The plant is selling power to local utility TNB under a 21-year PPA. The project’s levelized cost of energy is MYR 0.21608 ($0.051).
Stanford professors Paul R. Milgrom and Robert B. Wilson were awarded the 2020 Nobel Prize in economics for developing a new auction theory and new auction formats for goods and services. Their findings were already successfully used in the electricity energy sector and may now meet the challenge on how to better shape clean energy procurements.
The 18-meter long solar cell-clad trailer is said to enable fuel savings of 5-10% in Sweden. Swedish thin-film manufacturer Midsummer is a partner on the project.
Huanghe Hydropower Development has connected a 2.2 GW solar plant to the grid in the desert in China’s remote Qinghai province. The project is backed by 202.8 MW/MWh of storage.
Built in Gangba County, in Xigaze, Tibet, the 40 MW/193 MWh facility was deployed at more than 4,700m above sea level and is functioning as a demonstration project for the ancillary services the technology could offer the Tibetan grid.
International researchers have analysed the potential of sodium-based energy storage and found recent technical advances have arrived faster than those for the lithium-ion batteries which have been studied for three decades. Issues remain, however, before sodium constitutes a complementary option to lithium.
