A new report from the International Renewable Energy Agency (IRENA) shows that 24-hour solar and wind energy, combined with battery storage, provide power at a lower cost than new fossil fuel generation in regions with high-quality resources. May 6, 2026 Brian Publicover Firmly leveled electricity costs for solar plus storage range from $54/MWh to $82/MWh in high irradiation areas, IRENA says in its new report: “24/7 renewable energy sources: the economics of solar and wind energy.” That compares to $70/MWh to $85/MWh for new coal in China and more than $100/MWh for new gas globally. Since 2010, total installed costs…

Deze week verder Projecten wekelijkszet PowerBank Corp. stappen op het gebied van zonne-energie in de Empire State met twee projecten in de staat New York. Elders in het land heeft Xcel Energy goedkeuring gekregen voor de tweede fase van zijn “eerste in zijn soort” VPP-programma onder leiding van nutsbedrijven in Minnesota. Ten zuiden daarvan, aan de Golfkust van Texas, hebben GridStor en het Zwitserse energiebedrijf Axpo een “energieopslagovereenkomst” gesloten voor een zonne- en batterijproject…

A study from China shows that PV systems on the roof of milking parlors can significantly reduce roof heat flow and improve indoor thermal conditions. Field measurements and simulations have shown a reduction in indoor temperatures of 2.3 degrees Celsius during peak periods of heat stress in the afternoon. May 6, 2026 Lior Kahana A research team from China has investigated whether rooftop PV systems can help reduce heat stress in dairy barns. “This research provides quantified evidence to support advisory and decision-making processes for agricultural managers, agricultural policy makers and PV integrators,” the researchers said in a statement. “By…

Researchers in Brazil found that retrofitting commercial PV panels into PVT systems can increase overall efficiency by about 46-50%, but the added thermal resistance limits heat dissipation and reduces electrical performance somewhat. Their experiments showed that performance is limited by interface quality and system design, requiring improved heat dissipation capabilities. May 6, 2026 Emiliano Bellini Researchers from the Federal University of Paraná (UFPR) in Brazil have assessed the potential for retrofitting commercial photovoltaic modules into photovoltaic-thermal (PVT) panels, identifying practical limitations that currently limit the technical and economic feasibility of the approach. The scientists explained that previous research focused on…

Fraunhofer Institute for Solar Energy Systems ISE has opened a dedicated laboratory in Freiburg, Germany, to scale up perovskite-silicon tandem cell designs to large wafer sizes using industry standard processes. May 6, 2026 Brian Publicover Fraunhofer ISE has opened a new laboratory in Freiburg, Germany, to bring perovskite-silicon tandem PV closer to industrial production. The institute has already exceeded 33% efficiency on a laboratory scale by using a hybrid production route that combines vacuum and wet chemical deposition. The new Pero-Si-SCALE lab extends that work by scaling the technology to 210mm x 210mm wafer sizes using industry-standard high-throughput processes. The…

By Brad Kramer April 14, 2026 Renewable energy-focused architectural firm MMPV design has turned into a worker-owned cooperative. In this model, employees own and control the company, electing their colleagues to the board of directors and sharing the profits. The company made the change when Mariana Moncada, who owned MMPV Design for fifteen years, chose to sell the company to her employees so that ownership would pass into the hands of those who helped her build the company. MMPV Design focuses on projects that advance solar energy, energy storage and electric vehicle infrastructure in the United States. “I believe that…

Underneath almost every solar field, out of sight and often out of mind, lies a network of underground cables whose unexpected failures have become one of the industry’s most pressing reliability issues. Unlike cables in a typical utility that operate at a rated load of 25%, renewable energy power cables typically operate at a load of 90 to 110%. These “feeder” cables extract energy from the solar field and send it to the electricity grid of the local energy supplier. The power is then mixed with other power sources and ensures that the entire electricity grid continues to function optimally.…

Indonesia’s PLN has launched a tender for a 1,225 MW solar project that will be spread across several regions of the country. The state-owned company has not publicly announced a closing date. May 5, 2026 Patrick Jowett Image: mz romadhoni/Unsplash Indonesian electricity company PLN has opened a tender for a solar energy project with a total capacity of 1,225 MW. The Mentari Nusantara I solar project will be developed in multiple regions Indonesiawith 35 MW planned in Sumatra, 340 MW in Kalimantan, 600 MW in Java, 50 MW in Sulawesi, 80 MW in West Nusa Tenggara and 120 MW in…

What the Freedom Forever Bankruptcy Means for Your Solar System On April 15, 2026, Freedom Forever — one of the largest residential solar installers in the United States — filed for Chapter 11 bankruptcy protection in the U.S. Bankruptcy Court for the District of Delaware (case 26-10522). Court filings report estimated liabilities between $500 million and $1 billion. The company, which operated across more than 30 states including North Carolina, cited financial distress, an industry-wide demand slowdown, and an ongoing investigation into its sales practices by the Texas Attorney General. If you have a Freedom Forever solar system in North…
