Dutch startup offers roof coating increasing PV safety
AllShield Coatings says that its fire-resistant product can be installed under a new roof covering or applied to the roofing material of existing roofs. It weighs 2.8 kg/m2 and reportedly serves as an effective fire-resistant layer, significantly reducing the risk of fire spreading.
Different dust, different impact on PV module performance
Scientists in Germany have collected dust from Qatar, Morocco and Thailand to analyze the impact on the performance of uncoated solar glass and uncoated PV mini-modules. Their analysis has shown that dust coverage could range from 4% to 60%.
Despite low gas prices, solar, wind remain cheapest sources of power in US
Renewables remain cost-competitive in the United States despite rising natural gas competitiveness, according to Lazard’s 2025 “Levelized Cost of Energy+” report, which estimates combined cycle gas at $0.048/kWh to $0.107/kWh, solar at $0.038/kWh to $0.212/kWh, and nuclear at $0.141/kWh to $0.220/kWh.
Enertech unveils geothermal heat pump for residential use
The US-based heating specialist said its new variable-speed water–to–water system has a coefficient of performance of 3.2 at full load and 3.8 at part load.
Understanding P50, P90 and P99 in solar energy
A review of using statistical probability to understand solar production outcomes.
Solar companies adapt in changing times
pv magazine USA speaks with Solar Insure’s Dean Chiaravallotti about how solar companies can adapt business models, innovate product offerings, and deploy strategic tools to remain competitive in a shifting US market.
Coupling heat pumps with district heating
Researchers in Sweden have analyzed the impact of a hybrid heating system combining heat pumps and district heating on five real buildings. The analysis showed that residents were able to save up to €2,768 ($3,159) compared to a scenario without source coupling.
Global renewable energy pathfinding
Australia is tracking towards 75% electricity from solar and wind in 2030, which makes it a global energy transition pathfinder. Pathfinders are important because they learn to solve new problems and disprove misinformation and disinformation.
Cost of living, government rebates accelerate Australia’s solar and battery booms
Recent studies forecast Australia is on the precipice of a rooftop solar and household battery boom, predicting record breaking installation numbers driven by falling battery and solar module prices, government rebates and cost-of-living pressures.
Optimizing endless PV-driven heat pump scenarios for costs, self-sufficiency
Researchers have used mixed-integer linear programming-based multi-objective optimization to optimize 30,912 unique scenarios showing heat pumps operating in combination with PV power. The optimization modeling was conducted under day-ahead spot market prices terms.
