Solar above 60° North: The Arctic as PV’s next frontier

An IEA-PVPS report finds that solar power above 60° North is not only viable but rapidly expanding, driven by cold-climate performance gains, bifacial technologies, and rising energy security needs. While challenges like extreme seasonality, snow, permafrost, and scarce data remain, Arctic PV is emerging as a critical—and technically distinct—frontier for global solar deployment.

Perch Energy and Solstice merger scales to 3 GW amid global energy volatility

The combined community solar platform aims to insulate 16 states from rising retail electricity rates and fossil fuel price spikes through automated subscriber management and expanded project pipelines.

National laboratories lead multi-agency push for solar cybersecurity standards

The Department of Energy is deploying a research framework across four national laboratories to harden the domestic power grid against digital vulnerabilities as solar deployment accelerates.

NV Energy demand charge proposal threatens Nevada rooftop solar

A proposed shift in rate design could undermine the economic value of distributed generation and complicate the state’s energy transition goals.
