The long read: Understanding solar MLPE

Module-level power electronics, most often in the form of power optimizers and microinverters, offer a range of value propositions, including advanced monitoring capabilities. But how much can the little box behind the module really see, and how much do operators actually need to know to keep a power plant running optimally?

The long read: Nickel and dime batteries to LFP

Lithium-ion phosphate batteries are making a comeback. Thanks to high nickel prices and limited feedstock supply, the EV industry is driving this change. There is no need to fret about the onset of slightly lower energy density, though, as this development has some benefits for the stationary storage market.

AI identifies a $14bn solar problem

How do you know when an inverter or module is under-performing? Monitoring services should shed light on problems but AI-driven digital asset manager Raycatch says much information is hidden behind a wall of “noise.” Breaking that wall with advanced data analysis could unlock billions of cost savings.
