Exploring the future of legacy commercial solar.
Transformer shortages are emerging as a major bottleneck for the energy transition, with lead times stretching up to five years and costs rising sharply. As demand from renewables, electrification, and data centers grows, the pace of grid expansion is now limited by how fast this critical equipment can be manufactured.
Plug-in balcony solar systems are widely used across Europe, with more than 700,000 installed in Germany alone. In the U.S., new state legislation and safety standards could soon make these simple plug-in solar panels more accessible to renters and apartment residents.
New 2025 trade data shows the U.S. imported 33 GW of solar modules and 21 GW of cells, even as domestic manufacturing expands. The U.S. solar market now runs on both growing local capacity and continued global supply, raising new questions about cost and competitiveness.
PJM approved $11.8 billion in new transmission projects as electricity demand from data centers and large industrial loads accelerates. The grid buildout, including major 765-kV lines and a new HVDC backbone in Virginia, signals how utilities are preparing for rapid load growth across the Mid-Atlantic and Midwest.
New York has finalized rules under the RAPID Act aimed at cutting transmission permitting timelines by up to 50% while maintaining environmental standards. The reform centralizes review of large renewables and high-voltage lines under ORES, addressing one of the biggest bottlenecks to meeting the state’s clean energy targets.
Researchers in Australia developed a rule-based method that detects solar system underperformance using only AC-side inverter data. Tested across more than 1,000 PV systems, the approach achieved over 90% accuracy for major issues and could help operators manage large distributed fleets without expensive new sensors.
