Go with the flow (batteries)
There is a gap in the market for long-duration energy storage (LDES), according to US-based manufacturer ESS Inc. – one which can’t be plugged with lithium-ion chemistry. Hugh McDermott, of ESS Inc. tells pv magazine how he thinks iron flow batteries fit into the energy system of the future, as the company pursues global expansion.
Higher voltage faces greater resistance
Utility-scale solar is set to crank up the voltage, preparing to shift from 1.5 kV to 2 kV on the DC side. It is a move that could redefine PV system design and slash costs, but it won’t happen globally due to vastly different regulations as voltages rise, reports Tristan Rayner.
Canadian startup secures patent for solar module cooling tech
Enertopia has developed a solar module cooling system that uses a moisture collection layer to transfer heat while capturing water for irrigation in arid regions. The design channels heat from the panel to a liquid transfer system, improving efficiency and water use.
The next industrial revolution
The past 20 years have seen remarkable shifts in technology, from smartphones to solar and the electrification of transport. Clean energy and technology consultant Gerard Reid argues that an even bigger shift is looming, with the combination of clean electricity and AI set to usher in an “era of electrification intelligence.”
Global utility-scale solar additions hit 182 GW in 2024
Utility-scale solar installations reached 182 GW (AC) in 2024, with the top 33 countries now accounting for 765 GW, or roughly 93% of the global total, according to Wiki-Solar.
Trump executive order places 25% tariff on aluminum and steel
Aluminum is used in solar panel frames and racking and steel is used in solar ground mounts and trackers.
Colorado permitting red tape adds thousands to rooftop solar cost, finds study
Instant permitting and remote inspections can lower cost and drive installations in the state, according to a study by Brown University, Greenhouse Institute and Watson Institute.
