Residential PV

The Slovenian National Building and Civil Engineering Institute (ZAG) has introduced a fire safety test that simulates a fire starting on the roof membrane beneath a PV system. The researchers noted the importance of realistic construction methods, including factors such as anchors, adhesives, membrane welding, and ballast use.

In a new weekly update for pv magazine, Solcast, a DNV company, reports that atmospheric conditions led to variations in solar conditions across North America. According to analysis using the Solcast API, ISO New England and PJM outperformed long-term trends in capacity-adjusted performance, whereas ERCOT performed only slightly above average.

Greece installed 400 MW of net-metered PV systems in 2024, bringing its cumulative distributed solar capacity to 850 MW. However, the country shifted from net metering to net billing in September.

Scientists in Spain have used genetic algorithms to optimize a feedforward artificial neural network for the prediction of energy generation of PV systems. Genetic algorithms use “parents” and “offspring” solutions to achieve better results in subsequent generations.”

The average cost of an 11 kW rooftop solar installation after federal tax credits is $20,552 in the United States, said marketplace operator EnergySage. What will your utility-provided electricity cost over the next 25 years?

PM Surya Ghar: Muft Bijli Yojana, the world’s largest domestic rooftop PV initiative, aims to power 10 million households in India with solar power by March 2027.

Scientists in China placed a 0.5 mm thick aluminum foil between the solar cell and the EVA, and between the EVA and the glass layer. The two experimental modules were compared to a reference module and were found to dissipate heat and increase the in-plane temperature uniformity.

Challenges and innovations drive solar and energy storage inverter industry forward in 2025.

Ember, a London-based energy think tank, says in a new report that Turkey’s cumulative installed PV capacity has doubled to 19.6 GW in just two and a half years, driven by a surge in self-consumption projects.

At the recent World Future Energy Summit in Abu Dhabi, Octopus Energy’s founder and CEO Greg Jackson urged market participants in the renewable energy sector to tap low-cost renewables to drive both clean energy adoption and acceptance. His speech was part of IRENA’s Innovation Day at WFES on January 14, 2025 and set the scene for a subsequent panel discussion on the topic “Digitalization to support the 3x Renewables Goal.”
