Residential solar panels are often sold with long-term loans or leases, with homeowners entering contracts of 20 years or more. But how long do panels last, and how resilient are they? Panel life depends on several factors, including climate, module type, and the racking system used, among others. While there isn’t a specific “end date” for a panel …
The topic about cleaning solar panels is a sensitive one among solar panel owners. Some say it is absolutely necessary, while others claim that rainwater is enough to wash away any dirt the panels may have. The most correct answer lies somewhere in the middle. Rainwater will wash away some contamination that builds up on …
The Chinese Module Marker (CMM), OPIS’ benchmark assessment for modules from China, declined for a second week running to $0.198 per W as dramatic downslides in the country’s upstream segments pushed module prices to their lowest level in almost three years, according to OPIS data. This 7.48% plummet – the largest percentage drop so far …
The latest PV price forecast from CEA predicts that module prices in China will fall by about 15% from the fourth quarter of 2022 to the fourth quarter of 2023, as polysilicon prices continue to slide. The engineering consultancy said that from 2023 to 2024, TOPCon prices will remain higher than PERC. “As many new cell lines …

It’s an increasingly known fact that solar panels are a great way to reduce our carbon footprint. But we can’t simply install these systems and expect them to endlessly work at full capacity. Yes, it is true that, technically, there isn’t an expiration date for solar panels. Still, as time goes by, their …
Longi Solar said it will invest CNY 42.5 billion to more than double its PV wafer and cell capacity. It plans to build new wafer and cell factories. The company signed an investment agreement with the local government of Xixian New District, Shaanxi province. Construction of the new facilities should take no longer than 18 months …
Longi plans new 100 GW wafer plant, 50 GW solar cell factory in China Read More »
Soiling – where PV modules become coated with dust, dirt, sand or snow and thus receive less sunlight – is still an underestimated problem for solar power systems. Specialized solutions are now available in the form of anti-soiling glass coatings, automated and manual cleaning products, and models to predict the ways to use them most …
Researchers from the University of Luxembourg and the University of Utah in the United States have discovered that the increase in solar cell efficiency over the past few decades was strictly related to R&D, which underscores the crucial role of scientific institutions in the race to turn PV into the future of global energy. “Normally, the efficiency performance progress …

JinkoSolar has announced a new world record for n-type solar cell efficiency, at 26.4%. The achievement has been confirmed by China’s National Institute of Metrology, making it the seventh time that Jinko has raised the bar for n-type cell efficiency with its tunnel oxide passivated contact (TOPCon) technology. The record surpasses Jinko’s previous achievement of 26.1%, announced …
Chinese PV module maker Longi has revealed that it has achieved a power conversion efficiency of 26.81% for an unspecified heterojunction (HJT) solar cell, based on a full-size silicon wafer, in mass production. The result has been confirmed by Germany’s ISFH. “We cannot disclose if the cell is n-type or p-type at this stage,” a company spokesperson told pv magazine. …
