Perovskite tandem PV for agrivoltaics Researchers evaluated “farm-to-fork” life-cycle impacts of agrivoltaic lettuce systems using perovskite–silicon and perovskite–perovskite tandem PV, comparing them with conventional silicon PV across major US growing regions. The study finds that integrating advanced tandem solar with farming can reduce irrigation demand and significantly cut greenhouse gas emissions—potentially offsetting up to 30.9 million tons of CO₂ and saving around 8.4 billion m³ of water annually under favorable conditions.

Lessons from the solar frontier Utility-scale solar projects are larger, interconnections are slower, and engineering decisions must anticipate regulation and supply chains years in advance. At the CT Solar Platform in Snyder, Texas – a 1.6 GW AC single-site development – the first phase, CT Solar One (110 MW AC), has been a test bed for integrating civil design, BOS optimization and domestic-content strategy. Levona Renewables led the development and engineering of the project and CEO Fernando Queiroz shares some key lessons.
