Fighting coastal corrosion
Salt in the air can wreak havoc with projects that lack the necessary corrosion resistance, proving costly for asset owners or the engineering, procurement and construction (EPC) companies that built them. Alexander Gebert, sales director at Tobsteel, argues that quality stainless steel fasteners can save costs for solar investors and engineering, procurement and construction (EPC) contractors in the long run.

Hitachi launches CO2 heat pump water heaters with solar-friendly tariff controls
Hitachi has introduced its Y-series EcoCute CO2 heat pump water heaters in Japan, with 370-liter and 460-liter models set to launch from November 2026.
The upgraded range adds expanded support for daytime electricity tariffs and PV-linked energy management, alongside a five-year manufacturer warranty.
Heterojunction’s long road to the US solar factory
For a cell technology that has spent much of the past three decades on the verge of a breakthrough, heterojunction (HJT) is enjoying another moment in the spotlight. This time, however, the setting is somewhat unexpected – rather than the established manufacturing centers of China and Southeast Asia, some of the most significant new commitments to HJT are emerging in the United States, Finlay Colville reports.
