Indian solar equipment maker Swelect has launched a new range of hybrid solar inverters aimed at commercial and industrial customers. The product line is designed to combine solar generation with battery storage, helping businesses cut grid dependence and manage energy costs. The launch was reported by pv magazine Global.
- 5Ukraine adds 1.1 GW of solar capacity in first half▼"Ukraine adds 1.1 GW of solar in H1" # Ukraine # Energy # Renewables # SolarPower https://www. pv-magazine.com/2026/09/2
Ukraine installed 1.1 GW of new solar capacity in the first half of 2026, according to pv magazine. The figure highlights continued growth in the country's renewable energy sector despite the ongoing war, with observers pointing to solar's role in strengthening a battered and decentralized power grid.
- 6Rooftop solar growth makes New England gas plant obsolete▼Rooftop solar growth makes giant New England gas plant obsolete as region hits 500th Duck Curve day
Rooftop solar adoption in New England has grown so large that a major gas-fired power plant is being considered obsolete, according to pv magazine USA. The region has now recorded its 500th 'duck curve' day, when midday solar generation suppresses grid demand, reshaping how the power system is run and undermining the economics of large conventional plants.
- 7US homeowners' mistrust of solar companies eases slightly▼U.S. homeowners are now slightly less mistrustful of solar companies
Trust in solar companies among US homeowners has improved slightly, according to reporting by pv magazine Global. The finding suggests the residential solar industry may be gradually recovering from earlier reputational problems tied to aggressive sales tactics and installation disputes. The shift matters for installers and manufacturers betting on continued growth in home solar adoption.
- 8US team claims stability record for tin perovskite solar cell▼U.S. team claims stability record for 16.19%-efficient 2D/3D tin perovskite solar cell
A U.S. research team reports a stability record for a 2D/3D tin perovskite solar cell with an efficiency of 16.19%. The cell is lead-free, which matters because tin perovskites are seen as a less toxic alternative to lead-based designs, but they have historically degraded quickly. The claim, covered by pv magazine USA, suggests progress in combining decent efficiency with long-term durability.
- 9Overview Energy to build homing beacon for space-based solar power●Overview Energy to develop homing beacon for space-based solar transmission
Overview Energy says it will develop a homing beacon to support space-based solar power transmission, according to pv magazine USA. The beacon would help precisely direct energy beamed from orbit to receiving stations on Earth. The announcement has drawn attention as space-based solar power moves closer to commercial development, with companies racing to solve the challenge of safely and accurately delivering power collected in space to the ground.
