A large sheep farming company in Germany is seeking PV asset owners who will let its animals graze sustainably at solar project sites, in a move that could be a win-win situation for everyone.

Brazilian consultancy Greener has conducted a survey of more than 500 solar companies in Brazil to assess the economic impact of the Covid-19 pandemic. The results show that demand has already started to slow down, and that PV system prices are on the rise.

According to a Norwegian group of researchers, the reactive power capability of three-phase voltage source inverters can help to reduce problems caused by the intermittent nature of solar power on distribution networks. The scientists claim they are preferable to expensive grid infrastructure such as under-load tap changing transformers, step voltage regulators, and fixed and switchable capacitors. The group has developed a system model featuring a 7.63 kW PV array module, a three-phase voltage source inverter with 9.5 kVA of capacity, a boost converter, a three-phase dynamic load, and a utility grid.

Chinese scientists have developed a single-layered organic solar cell based on non-fullerene acceptors with improved fill factor and short-circuit current density. They achieved their results with a new morphology that could be more suitable for vertical charge transport.

SunPower CEO: “We remain on track to complete our planned company split into two independently focused pure-play solar companies by the end of the second quarter.”

Antonio Delgado Rigal, chief executive of energy forecasting service Aleasoft, has told pv magazine all unsubsidized solar project financing will be postponed until it is possible to make reliable price predictions again. Projects could change hands in the meantime though, thanks to deep-pocketed investment funds on the lookout for bargains.

Researchers in Brazil have suggested using solar radiation databases and simulator software to scale PV-diesel mini-grid generators. The profiles of PV generation and mini-grid load demand are critical to finding the right balance, according to the academics.

Researchers in Italy extensively analyzed four different configurations of their proposed system to assess its potential, including under non-optimal, ‘off-design’ conditions and concluded that, for now, subsidies would still be required for the commercial production of synthetic natural gas.

The country’s power utility has completed the pre-selection process to seek developers for a 20 MW solar project in the Banjul region. The project will feature up to four PV plants and will be developed under the national Electricity Restoration and Modernization Project.

Analysts from German energy advisory Enervis have told pv magazine power purchase agreement-linked solar projects which are under development in Europe may be delayed by the Covid-19 outbreak and new unsubsidized projects appear unlikely any time soon, thanks to the current economics.
