BMT-G4/088A | 335W | BMT-G3/088A |

 315W Ultra-lightweight Solar Panel

The GoodWe Galaxy Series is a revolutionary type of solar panel categorised as Building-integrated photovoltaics (BIPV). Unlike traditional solar panels with aluminium frames, the Galaxy Series boasts a frameless design and utilises ultra-thin tempered glass. This translates to a feather-light weight of around 6kg per square meter, a significant reduction compared to the standard 18 kg-25 kg of conventional panels.

If you have a roof with limited weight capacity or prioritise a sleek solar solution, the Galaxy Series is definitely worth considering.

Is the GoodWe Galaxy Series right for you?

While the Galaxy Series offers a unique set of advantages, it’s not a one-size-fits-all solution. Here’s how to decide if it’s the right choice for you:

  • Limited roof capacity: If your roof has a weak structure that can’t support the weight of traditional solar panels, the Galaxy Series is a perfect solution. Its featherweight design minimises stress on your roof, making solar power a viable option.
  • Waterproofing concerns: The frameless design and zero-penetration mounting methods (clamping, gluing, or hot air welding) eliminate the risk of leaks associated with traditional solar panel installations. This makes the Galaxy Series ideal for roofs with compromised waterproofing or flat roof applications.
  • Aesthetics: The Galaxy Series’s sleek, frameless design can complement your home’s architectural style, creating a more integrated and visually appealing solar installation.
  • Budget: While the lightweight design can lead to faster installation and potentially lower labour costs, the Galaxy Series might cost more upfront than traditional panels.
