Solar PV

TÜV Rheinland has verified the performance of the Soltec Diffuse Booster algorithm, which uses both sensors and weather forecasts to drive its solar trackers. According to the manufacturer, it can increase the annual revenue of a 100 MW PV plant in Spain by €1.8 million.

A German research team has developed a photovoltaic-electrochemical device for alkaline water electrolysis that can be linked to battery storage. The proposed system configuration can not only smoothen out the PV power fluctuations and facilitate power coupling, but also improve solar to hydrogen efficiency.

The efficiency of the module was certified by the U.S.’ National Renewable Energy Laboratory. It was built with perovskite solar cells with a stabilized efficiency of 23.6%, an open-circuit voltage of 1.17 V, a short-circuit current density of 24.1 mA per cm−2, and a fill factor of 0.842.

Acme Solar said the facility would use 3 GWp of solar and 0.5 GWp of wind energy to produce 2,400 tons of green ammonia daily and approximately 900,000 tons annually. Construction is planned in phases with an investment of $3.5 billion over the next three years.

The comparison of two solar cladded roofs in Sydney, Australia, one bare beneath its panels and the other adorned with native grasses and plants, has found the panels on the green roof were, on average, 3.63% more efficient, producing an average daily output 13% greater than the conventional roof. The improvements are believed to stem from the lower temperatures on the green roof, thanks to its plants – which also provided a plethora of additional benefits.

The battery was built with a new catholyte and a symmetry-breaking strategy, which consists of changing the symmetry of the redox-active organic molecules instead of using the common approach of attaching a hydrophilic functional group.

The South African authorities have published the list of projects competing in the the fifth round of the Renewable Energy Independent Power Producer Procurement Program (REIPPPP). It seeks to procure 1 GW of PV and 1.6 GW of wind power.

Most of the generation capacity – around 190 MW – was deployed in the emirate between September 2019 and March 2021.

According to a recent study, installing an air source heat pump may increase a home’s value by up to 7.1% in 23 states of the United States. The price premium is estimated at between $10,400 and $17,000 per transaction and the average cost for installing an air source heat pump is around $8,000.

The state-run energy company has commissioned a 25 MW plant on the reservoir at its Simhadri thermal power station, in the state of Andhra Pradesh. The installation features more than 100,000 solar modules.
