Distributed solar accounted for 15% of all new U.S. power capacity in 2025 as residential and community projects reached record installation levels.

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.

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

Achieving a system cost of $0.65 per watt through the secondary market and DIY assembly demonstrates a viable pathway for U.S. plug-in solar to provide immediate utility bill relief to renters and apartment dwellers.

The United States is at a critical inflection point where speed to deployment of energy technologies contributes to economic strength and energy security, but policy certainty is paramount, according to a panel of three solar manufacturing experts.

The U.S. International Trade Commission (ITC) has opened a Section 337 investigation into tunnel oxide passivated contact (TOPCon) solar cells, modules, panels, and related products following a complaint by First Solar, naming 47 entities across 11 countries as respondents.

Industrial battery manufacturer EnerSys is closing its legacy lead-acid facility in Tijuana, Mexico, consolidating production at its Springfield, Missouri plant, where it makes a new type of lead-acid battery it says is better suited to the demands of modern data centers.

A new California bill, SB 913, would require state regulators to integrate customer-owned batteries and electric vehicles into the official Resource Adequacy market to bolster grid reliability.

The Terawatt PV 100 ranks the top 100 solar manufacturing companies using a new methodology based on production scale, financial strength, and corporate transparency, with Tongwei leading the Q1 2026 list and most top firms headquartered in China. The analysis highlights increasing global supply-chain scrutiny driven by tariffs and ESG mandates, while also showing rising influence from Indian companies and strong positions for key materials and equipment suppliers.

The Connecticut-based company secured an additional $250 million, reaching $550 million total, led by Global Infrastructure Partners to accelerate the deployment of solar and energy efficiency upgrades across the U.S. commercial mid-market.
