Solar-plus-storage for the Cook Islands
Around 4.2 MWh of energy storage capacity will be connected to a solar and diesel micro-grid on Rarotonga, the largest of the islands in the South Pacific nation. Three 40-foot containers with a total power output of 4.8 MVA will be used as a power reserve and for grid support by utility Te Aponga Uira.
NREL scientists encourage ‘optimal’ PV curtailment
Solar curtailment might become a valuable aspect of future PV deployment, particularly if grid operators start focusing on ‘curtailment management’ instead of ‘curtailment prevention.’ Management would include measures such as flexible generation, storage, load flexibility, and regional coordination.
Inverted pyramid-based PERC solar cell with 21.4% efficiency
A Chinese research group has developed a PERC cell on a commercial 180-μm-thick monocrystalline silicon wafer with a standard size of 156 × 156 mm2. The cell has an open-circuit voltage (VOC) of 0.677 V, a short short-circuit current (ISC) of 9.63 A, and a fill factor of 80.30%.
Global green hydrogen project pipeline reaches 50 GW
International thinktank IEEFA says there are 50 viable green hydrogen projects under development with an estimated renewable energy capacity of 50 GW and the potential to produce 4 million tonnes of the fuel annually.
Construction begins on 60 MW floating PV plant in Singapore
The plant will sell power to Singapore’s Public Utilities Board under a 25-year PPA. The project is located at the Tengeh Reservoir.
Jinko unveils new 610 W solar panels
The Chinese manufacturer introduced new PV modules this weekend at the SNEC solar exhibition in Shanghai.
Solar tile with passive cooling
Researchers built the device by attaching 17%-efficient monocrystalline PV cells to a mortar roof tile that was doped with a phase-change material (PCM). The PCM solar tile provided 4.1% more power than the PV tile with no cooling agent in the winter, and 2.2% to 4.3% more during the summer.
Solar for parking machines
New Zealand researchers have proposed a way to assess the technical and economic feasibility of PV-powered parking machines. Solar might be an ideal solution, but the siting of the machines is critical and should be planned in advance, in line with available solar radiation and potential shading.
Philippines’ nexus approach for water and solar power supply
The country’s National Irrigation Administration will bet on floating PV and solar-powered irrigation to improve water and energy supply. The Pantabangan and Casecnan dams, in the province of Nueva Ecija in the Central Luzon region, have been identified as ideal locations for floating solar.
Jinko claims 24.79% efficiency for n-type monocrystalline cell
The Chinese manufacturer has claimed a world record for a large-size, contact-passivated solar cell. The result, certified by Germany’s Institute for Solar Energy Research in Hamelin, betters the company’s previous record by almost 0.6%.
