JinkoSolar unwraps 415 W PV panel for rooftop applications

The new, Tiger Pro 54HC panel is based on a 182mm, 54-cell design and exhibits an efficiency of up to 21.3%. The manufacturer claims the new product is particularly suitable for residential projects in high snow or high wind load areas.

How to protect rooftop PV systems from fire risk

Dutch research institute TNO has released a series of guidelines to reduce fire hazards in rooftop PV installations. The study follows a series of fire accidents that occurred between 2018 and 2020 in the Netherlands, for which the main causes were identified.

Holographic film to protect solar panels from overheating

Russian scientists have developed a holographic film based on prismatic concentrators that reduces the operating temperature of solar panels, including thermal-photovoltaic devices. They claim the patented, low-cost technique can even improve PV module efficiency in cloudy weather.

Hydrogen shipping vs submarine cables

Hydrogen transportation and submarine power lines have been compared by an international research team to find out which may be the cheapest option to connect for energy exchange regions separated by the sea. According to their findings, the hydrogen shipping alternative does not present very good prospects of applicability in the future, unless some disruptive technological breakthroughs are made. What makes compressed and liquified hydrogen ships still attractive, however, is that they can export energy almost anywhere, and that electrolysis and liquefaction plants are relatively easy to expand compared to marine cables.

Malaysia’s 1 GW PV tender attracts lowest bid of $0.0429/kWh

Through the fourth tender of the LSS program for large scale PV, the Malaysian authorities have pre-selected 30 solar projects with a combined capacity of 823 MW. The lowest bid came in at MYR0.1768/kWh ($0.0429) and the highest at MYR0.2481/kWh.

Trina launches 670 W solar panel

The latest product in the Vertex series from the Chinese manufacturer has a power conversion efficiency of 21.6%.

Passive solar module cooling based on hydrogels beads and nanofluids

A British-Egyptian research group has tested the use of hydrogels beads for PV module cooling. The micro-sized particles were saturated with aluminium oxide (Al2O3) water-based nanofluids and placed below the simulated PV panels. The experiment showed, according to the scientists, that the hydrogels beads were able to significantly reduce the temperature by between 17.9 and 16.3 degrees Celsius.

Hybrid operational strategy to use lithium-ion storage in commercial PV arrays

Lithium-ion batteries can not only improve self-consumption in commercial PV systems but are also able to efficiently perform peak shaving and price arbitrage, according to an international research group which has proposed a new strategy to calculate the best system configuration in terms of costs and revenue. The scientists specified, however, that the novel strategy may become effective only if storage system prices will drop under $250/kWh.

Vietnam sees 350 MW solar park come online

Chinese inverter maker Sungrow revealed a 350 MW solar facility was energised in Loc Ninh County, Binh Phuoc Province. The project secured a FiT of $0.0709 per kWh.

Australia-based Enegix Energy planning $5.4bn Brazilian green hydrogen plant

The facility is expected to be located in the state of Ceará and to be powered by around 3.6 GW of wind and solar facilities located in the region. The project developer is Australia-based Enegix Energy.
