Three-year field test shows TOPCon, HJT solar module reliability in desert areas
A three-year field experiment comparing the performance and reliability of passivated emitter and rear cell (PERC), tunnel oxide passivated contact (TOPCon), and silicon heterojunction (SHJ) modules in desert climates found that HJT modules exhibited the highest degradation, while TOPCon modules showed the lowest degradation.
New method to optimize bifacial PV system performance in residential applications
Scientists in Qatar have outlined a new approach to optimize residential bifacial PV systems by combining south-facing and vertically mounted east-facing configurations. The novel methodology reportedly results in a 21.6% increase in a system’s net present value.

Turkish sensor maker debuts pyranometer for PV plants
Turkey-based Seven says its new product can measure irradiance in a range of 0 W/m² to 4,000 W/m², with a resolution of 0.1 W/m². It can also measure humidity and temperature.
Almaden plans solar glass factory in UAE
China’s Almaden says it will build a solar glass plant in the United Arab Emirates with an annual capacity of 500,000 tons, in line with its plans to globally expand as domestic profits fall.
How to combine photovoltaics with rainwater harvesting
Scientists have developed a system that harvests rainwater running off PV panels for household use or hydrogen production. Their analysis showed that, in the southern Sahel, the system can meet both the energy and water requirements for electrolysis, with surplus rainwater covering up to 50% of a household’s daily water demand.
The Hydrogen Stream: Scandinavia, Italy may produce grid hydrogen by 2030
Aurora Energy Research says the global electrolyzer pipeline now totals around 1.3 TW, with 114 GW in development and 32% expected online by the end of 2026. The firm cites stronger EU policy support and growing momentum in hybrid power purchase agreements (PPAs).
