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, ...

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

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 ...

The solar industry has fought for decades to earn its reputation as the fastest, cheapest way to decarbonize the grid. But in 2025, as deployment accelerates and policy support wanes, the industry ...

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 ...

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.

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 ...

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.

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