Developers have until September 30 to lodge their interest to install grid-connected floating solar plants on the water reservoir surface at Salaulim, Amthanem, Anjunem, and Chapoli Dams in the Indian State of Goa. Their scope of work also includes assessing the floating solar potential at each of these locations.

National Renewable Energy Laboratory researchers have studied which tech offers the lowest levelized cost of energy to provide the US Western Interconnection grid with electricity when wind and solar are not available. They assumed 85% renewables penetration and determined that geologic hydrogen storage and natural gas combined-cycle plants with carbon capture storage are the cheapest options for 120-hour discharge applications. 


The recent auctions for solar parks in Agar (550 MW), Neemuch (500 MW), and Shajapur (450 MW) districts of Madhya Pradesh saw winning tariffs in the range of INR 2.14 (0.029 US$) to INR 2.459 (0.034 US$).

The Indian manufacturer has introduced the HELOC̣ Pro series featuring mono-facial and bifacial modules based on M10 (182mm x 182mm) wafer size. 

Pyramid Electronics has unveiled three-phase string solar inverters based on silicon carbide power devices. The inverters are available in power ratings ranging from 5 kW to 15 kW, including models with three maximum power point trackers.

Scientists have demonstrated a zinc-ion battery that overcomes many of the challenges for this technology. By working with a highly-concentrated salt solution as the electrolyte, the group was able to achieve stability over more than 2,000 cycles combined with a strong electric performance. The group says that its work opens up “a viable route to developing aqueous batteries for emerging electrochemical energy storage applications.”

Installers have until September 10 to apply for getting enlisted with Central Electronics Limited (CEL) to carry out the work for grid-connected, ground-mount solar plants. The plants are to be set up in sizes of 2 MW to 10 MW.

The UK-headquartered steel major is mulling to set up a 4.5 GW solar park in Rajasthan with an investment of INR 19,000 crore. It also plans to invest in Gujarat’s solar energy, wind energy, and hydrogen gas production sectors.

Thermal energy storage is dense, efficient, and suitable for greenfield and brownfield projects, with a potentially long lifespan. It can also be built with recyclable or low-impact storage materials. So why is it taking so long to achieve widespread commercial success? Tristan Rayner explores the latest developments.

The Tiger Neo panel has a power conversion efficiency of up to 22.1% and a temperature coefficient of -0.30% per Celsius degree. The product is made with 182mm wafers, half-cut cells, and has a power output ranging from 590 to 620 W.
