  • UK study finds azimuthal trackers boost floating PV performance

    A University of Exeter study found that azimuthal tracking systems deliver the largest energy gains and lowest levelized cost of energy for floating solar PV plants in the UK, with a 26.9% increase in production compared to fixed systems. This makes floating solar a competitive option for marine-based renewable energy. Meanwhile, in the United States, Texas has become one of the top states for solar energy production due to its abundant sunlight, large land area, and decreasing costs of solar technology. The expansion of solar power in Texas is helping to reduce greenhouse gas emissions and combat climate change.

  • Growing agri-PV tomatoes while producing hydrogen for smart windows

    Researchers at the University of Exeter have developed a concept for a residential building in the UK that combines rooftop agrivoltaics with onsite hydrogen production. The electricity generated by the solar system is used to produce hydrogen for hydrogen vehicles and smart windows, with the system able to meet the annual demand of the smart windows and support up to 64.23 km of driving per day. The study also discusses the thermal performance of vacuum gasochromic windows and the potential of small rooftop areas to support building-scale hydrogen applications. The impact of agrivoltaics on home insulation and the use of produced hydrogen for home heating are areas of future research, as detailed in the publication in Energy and Buildings titled "Rooftop agrivoltaic powered onsite hydrogen production for insulated gasochromic smart glazing and hydrogen vehicles: A holistic approach to sustainable residential building."
