Tata Power Renewables installs 45,500 rooftop solar systems with 220 MW capacity in Q1 FY26
With Q1 FY26 additions, Tata Power Renewable Energy Ltd has crossed the milestone of over two lakh rooftop solar installations, bringing its cumulative installed capacity to 3.4 GW.
Photovoltaics for atmospheric water harvesting
A scientist in Turkey has simulated eight PV-supported hybrid atmospheric water harvesting systems and compared their performances. They were all considered to operate with R1233zd(E), R1234yf, and R600a, as well as R32 refrigerants. The required PV system size was as low as 20 m2.
The impact of module pricing on solar project viability: Trends and predictions
India’s solar sector faces rising module costs due to recent developments, including the imposition of anti-dumping duties on solar glass and China’s reduction in export rebates on solar modules, impacting project viability. These shifts underline the delicate balance between promoting local manufacturing, pursuing geopolitical strategies, and navigating the economic realities of global trade.
New research confirms residential PV tends to increase household power consumption
New Swiss research shows PV-powered homes can increase power consumption by up to 11% compared to non-solar households. This rise is linked to electric vehicle adoption or other high-usage appliances, which the study’s author notes is not inherently negative or wasteful.
Photovoltaics vs. photovoltaic-thermal
Researchers in India say that photovoltaic-thermal (PVT) systems offer greater performance stability than conventional PV systems in hot climates. Using irradiance and temperature data, the team applied a Random Forest model that predicted efficiency classes with 97% accuracy.
Ikea begins offering balcony solar kits
Swedish furniture retailer Ikea is selling plug-in solar kits in Germany, with storage-inclusive systems starting at €1,229 ($1,425) and reaching €2,800 for versions featuring four 520 W panels. The kits are designed for residential self-consumption and vary by capacity and configuration.
The role of advanced transformers in India’s green transition
Without resilient, responsive, and renewable-ready transformer networks, India’s decarbonization goals risk being destabilized by the very variability they aim to harness.
New study estimates India’s solar potential at 10,830 GW
A new study by The Energy and Resources Institute (TERI) has estimated India’s total solar potential at 10,830 gigawatts (GW), significantly higher than the previous 2014 assessment of 748 GW by the Ministry of New and Renewable Energy (MNRE). The study revisits conventional solar deployment areas such as barren and unculturable lands and explores additional avenues to expand the country’s solar potential.
U.S. residential solar on the brink of collapse
Residential solar is on a downturn, and things may get worse. In a shock for the industry, the latest draft of the “One Big Beautiful Bill Act” excludes residential solar lease providers from the Investment Tax Credit.
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%.
