Sekisui House-W is testing a pilot project consisting of a residential PV system, a small-sized electrolyzer, hydrogen-absorbing alloy tanks, and a fuel cell. The company said the hydrogen storage alloys used in the project have higher energy density than battery storage.

Scientists in Korea have proposed to use an algorithm that simulates the behavior of foraging bees to shape a new grid-forming inverter design. The approach is designed for both grid-connected and islanded inverters.

NREL researchers used acoustically spalled gallium arsenide substrate that reportedly reduces electrical shunting, resulting in potentially lower manufacturing costs. The cell achieved an open-circuit voltage of 1.061 V, a short-circuit current density of 29.9 mA/cm2, and a fill factor of 84.9%.

India has concluded a 2 GW solar tender with a tariff of $0.032/kWh. The winning developers can set up projects anywhere in the country, as long as they are connected to the interstate transmission system (ISTS).

Andreas Thorsheim, the CEO of Norway-based residential solar specialist Otovo, recently spoke with pv magazine about high inventory levels for solar modules in Europe and falling panel prices. He said there will be a strong buyer’s market this fall and noted that the latest modules off the boat are the cheapest.

The researchers of the Belgian research institute used a dual-layer treatment for the perovskite absorber, which they said improved the cell efficiency and stability. The device achieved an open-circuit voltage of 1.17 V, short-circuit density of 24.5 mA/cm2, and a fill factor of 84.6%.

An international research group has proposed to build a Sub-Sahara Africa (SSA) central grid across 12 countries in order to reduce energy poverty. The proposed transmission line would touch Mali, Niger, Nigeria, Chad, Sudan, Ethiopia, Uganda, Kenya, Tanzania, Burundi, Mozambique, and South Africa.

Namibian utility NamPower is seeking an engineering, procurement, and construction (EPC) contractor to build a solar farm in Rosh Pinah, a southern mining town. The project was originally designed for wind power generation.

French energy company EDF has built a new 40 MW solar farm in Ashalim, in Israel’s Negev Desert.

Luxembourg has kicked off its second tender for C&I solar projects ranging in size from 30 kW to 5 MW. It is offering rebates of up to €745 ($835) per kilowatt installed and up to 55% of the total cost of buying and installing systems.
