Technology and R&D

Researchers in Sweden investigated the complex non-linear tradeoffs between capacity expansion costs and reliability levels of off-grid PV mini-grids and found that capacity expansion based solely on cost-minimization may result in several reliability issues.

The new heat pump can purportedly provide hot water at a temperature of up to 70 C. It is specifically designed for climatic conditions with temperatures ranging from -10 C to 42 C, as well as coastal locations.

Riello Solartech has developed new hybrid inverters for rooftop PV, designed for commercial and industrial applications The Italian manufacturer says they have a European efficiency rating of roughly 98%.

The two research institutes said the multijunction solar cell is based on silicon, gallium indium phosphide (GaInP) and gallium arsenide (GaAs). The device utilizes a specially designed metal/polymer nanocoating that reportedly optimizes the distribution of light scattering beyond the total internal reflection critical angle in the cell.

S&P Global Commodity Insights says it expects China to install 170 GW of solar in 2023, with global capacity additions to potentially surpass 400 GW.

The International Energy Agency has warned that lagging policy support, rising costs, and supply chain disruptions threaten the profitability of low-emission hydrogen, while the Commonwealth Scientific and Industrial Research Organisation (CSIRO) has identified hydrogen seeps in South Australia.

Researchers from the Netherlands have assessed the potential integration of heat pumps, electric vehicles, and PV systems into distribution grids. They have discovered that suburban grids could face a higher risk of overload. By using actual data from Dutch distribution grid operators, they believe their methodology could be applied to study energy systems in other nations.

In a new weekly update for pv magazine, Solcast, a DNV company, explains that the climatology of Africa leads to very different seasonal generation patterns from what European solar producers experience. Data analysed by Solcast, via the Solcast API, shows this seasonal variance from summer to winter in 2023.

Indian researchers have assessed seven of NTPC’s solar plants in various climate zones. They used a fuzzy multi-criteria decision-making method to evaluate economic, technical, environmental, and connectivity issues.

China’s GoodWe has introduced specialized carport solar panels to the Australian market. The panels are designed to address concerns related to water drainage and wiring.
