Lab-tested solar module performance has improved over the last year, according to data from US-based technical advisory firm Renewable Energy Test Centre (RETC). In its 2025 PV Module Index Report, ...

Solar panel efficiency affects how much electricity your system can generate from the roof space available – here’s what that means and why it matters ...

If you stop to think about it, it’s a marvel that we can harness energy from the sun. But we do, thanks to solar panels equipped with photovoltaic cells that convert sunlight to electricity. That’s no ...

Kiwa PVEL, the independent lab for quality and reliability testing of solar photovoltaic (PV) modules, today announced a significant update to its photovoltaic (PV) module Product Qualification ...

Dutch-German quality assurance firm Sinovoltaics has released a free browser-based tool that generates project-specific lab ...

The Austrian manufacturer said its new glass-glass module features 108 back-contact TOPCon half-cells and a power conversion efficiency of 23.52%.

As the solar industry pushes for ever-lower costs, larger module sizes and greater energy output, the structural integrity and long-term performance of modules have become critically compromised.

There’s no single ‘right’ solar panel size for every home. The best system is one that balances your energy use, roof space ...

Researchers at Germany's Fraunhofer Institute have developed ShadeCut, a technology that applies patterned colored films to solar panels to mimic roof tiles, masonry, or custom designs.
