New MPPT approach for multi-string PV systems under partial shading

Egyptian researchers has developed a multi-string PV system with a converter control strategy, achieving 99.81% efficiency with a direct duty cycle for maximum power point tracking (MPPT).

Novel tool for PV system sizing allows users to assess tradeoffs between reliability and costs

Developed by scientists in Egypt, trhe Green Energy Solutions software allows users to assess the tradeoffs between the PV system reliability and its costs. Compared to PVsyst, it has an error margin of up to 9%.

Hydrophobic nanocoating to reduce soiling in solar panels

Scientists in Egypt have created a self-cleaning, hydrophobic coating for solar panels that reportedly increases their efficiency by more than 30%. They used a coating solution based on polydimethylsiloxane (PDMS) and silicon dioxide (SiO2) nanocomposites, mixed with ethanol and isopropanol.

Germany to import green ammonia from Saudi Arabia from 2026

Germany has decided to build its first green ammonia import terminal in Hamburg, in collaboration with Air Products. Egypt, meanwhile, has signed $128 billion of hydrogen framework agreements.

Ultra-fast synthesis of nanocomposites for sodium ion batteries, supercapacitors

Researchers in Egypt have developed a synthesis method that uses the high microwave absorbance of silicon carbide content in rice straw ash and takes just 60 seconds to produce sodium iron phosphates-carbon nanocomposites (NaFePO4-C), which can be used as sodium ion battery cathodes and as symmetric supercapacitors.

Fortescue proposes 9.2 GW green hydrogen project in Egypt

Mining magnate Andrew Forrest’s Fortescue Future Industries continues its campaign to be one of the world’s largest clean energy companies, announcing plans to develop a 9.2 GW wind and solar facility in Egypt that will power green hydrogen production in the Arab republic.

Coupling photovoltaics with thermoelectric cooling

An international research team has investigated how solar could be combined with thermoelectric coolers (TECs), which are small solid-state heat pumps used either for heating or for cooling. A system was built with six solar panels, an air duct system, four batteries, a charge controller, TECs, an inverter, heat sinks, a test chamber, and condenser fans.

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.

UPDATE: ACWA offered lowest bid in Egypt’s 200 MW tender

As pv magazine has learnt, the Saudi energy giant lowered its offer to $0.02752/kWh at the last minute, beating the bid lodged by Spain’s Fotowatio, which offered $0.02791 per kWh.
