Chinese solar exports rose by 64% in 2022, says Wood Mackenzie

China exported 154 GW of PV modules, 24 GW of solar cells, and 41 GW of wafers in 2022. In 2026, annual cell and wafer exports could hit 230 GW and module shipments could reach 149 GW, according to Wood Mackenzie.

Fraunhofer ISE produces hydrogen via PEM electrolyser with seawater

Fraunhofer ISE scientists have optimised a technical concept for a hydrogen plant at sea. They claim that their design is “technically and economically viable.”

Iberdrola using dogs, robots to monitor solar plants

Iberdrola is using a springer spaniel in a solar park to smell electrical problems that could lead to power cuts. It is also using a robotic dog to detect and analyse faults in substations.

US startup to build 100 MW solar plant with modules on ground

Erthos claims that with its new installation method, solar facilities could occupy just one-third of the surface covered by conventional PV plants, potentially reducing installations costs by up to 20%.

PVH’s success in Australia: ‘There are no obvious choices for us’

PV Hardware has become a leading solar tracker manufacturer in Australia, a market renowned for its growth, opportunities and difficulty. Pv magazine spoke to Alejandro Cantos, director of PVH for the Asia-Pacific region.

Space-based solar power for terrestrial energy needs

The Cassiopeia solar project aims to use the sunlight collected by a space satellite for terrestrial energy needs. The electricity generated would be converted to radio frequency microwave radiation transmitted to an antenna on Earth. The initial LCOE would be $73.4 (USD 47.8)/MWh, according to a UK study.

Agrivoltaics for vineyards

Developers recently commissioned two different wine-related agrivoltaic projects in Europe.

Update: New tech to produce hydrogen from tap water

A Spanish scientist has developed a system that reportedly produces hydrogen on-site without expensive electrolysis. The prototype utilises a water tank that is initially filled with water, ferrosilicon, and sodium hydroxide.


Fully autonomous robot for solar O&M

OnSight Technology has developed a tele-operated vehicle to clean solar arrays. It is equipped with a radiometric thermal imaging camera and an optical zoom camera backed by artificial intelligence. It has a range of 12 hours and a speed of 1.6 km per hour.

Hybridising PV, redox flow batteries and geothermal heat pumps

A Spanish consortium is equipping one of Madrid’s largest metro and bus stations with a hybrid system that combines PV, geothermal pumps, and vanadium redox flow batteries to provide cooling and heating.
