PV modules

The municipality of Drammen, Norway, has started testing a seasonal PV storage project that uses boreholes in the ground. The operators of the project are using electricity from PV modules to produce heat via a CO2 heat pump and outdoor air. The heat is produced by the CO2 pump during the spring, summer and fall, in addition to heat produced by solar thermal collectors.

The authorities plan to assign 2.26 GW of renewable energy capacity overall under the scheme, which will include other energy sources such as hydropower, wind, biomass, biogas, and geothermal energy. The government will provide projects it selects with a feed-in price premium, which will be paid for the power generated by the projects, on top of spot market prices.

The Italian government has raised the tax breaks it offers for building renovations and energy-requalification projects – potentially including storage-backed rooftop PV systems – to 110%. The new measure is part of the Relaunch Decree, which is a package of guidelines aimed at reviving the Italian economy in response to the Covid-19 crisis.

Twenty-three renewable-energy operators have resumed testing of their installations, just a few weeks after the Mexican government halted grid connections for new solar and wind power projects, pending further notice. Mexicio’s National Energy Control Center (Cenace) has faced a series of “amparo” lawsuits since the government introduced the new measures against renewables.

Scientists in the United States have created a quantum dot solar cell which has a photon-to-electron conversion efficiency of 85%. The device is also said to exhibit remarkable defect tolerance and toxic-element-free composition.

Not one wind power project was submitted to the German network authority for the April round of a national clean energy procurement program. Almost 204 MW of solar generation capacity was allocated across 30 solar projects with an average final electricity price of €0.053/kWh.

Inverter maker Sungrow is supplying the inverters and storage system for China’s largest, 202.8 MW/MWh solar-plus-storage facility. The plant will be connected to a new, 800 kV ultra-high voltage power line.

Production is set to start in the first quarter of next year at the planned fab in Greiz, Thuringia. The facility will manufacture 370 W panels featuring half cells, large wafers and nine busbars.

Quarterly new additions were 15% lower than in the October-to-December window. The France Territoire Solaire thinktank said the lower volumes could be explained by the initial impact of the coronavirus crisis.

Romgaz is reportedly planning to invest in solar, wind, geothermal and biogas power projects by tendering for consultants.
