Energy storage can be the “Swiss-army knife” of the electricity grid. Reports for more than a decade have demonstrated the value storage can provide. But now that states have moved from piloting energy storage to adopting it at scale, there is a..

Solar carports may look deceptively familiar to rooftop or ground mount projects: steel, modules, inverters, conduits. But not so fast! Treating carports that way is one of the most direct paths to rework, delays, and uncomfortable conversations..

Owners & developers want long-term performance. EPCs want to get steel in the ground and pass inspections.Between those two priorities lies the real challenge: how much of your project should be standardized, and when does customization pay off?
