CIGS sustainability

Sustainable Solar Panels

Green Energy’s CIGS Solar Panels are sustainable solar panels in multiple ways. Renewable energy is being generated, and the panels are made of much less raw materials than conventional crystalline solar panels.

Sustainability on the agenda

We exist to effect change

Being a supplier of solar solutions and working towards renewable energy can be seen as a goal in itself. But our story goes beyond just being a supplier of green energy. It is also a story about having respect for the planet and the people who live on it, which is why we produce some of the most sustainable solar panels available on the market.

Raw materials account for only 3% of our solar panels. They are also designed to separate and recycle. Specifically, our copper comes from cable scrap, while indium and gallium come from recycled TVs, flat screens and mobile phones, so we produce many square metres of solar panels from just one discarded iPhone screen.
EPBT, or Energy Pay Back Time, measures how long it takes for a solar panel to generate as much electricity as was used to manufacture it. Compared to C-Si solar cells, CIGS cells have a significantly lower EPBT due to their thinner design and reduced raw material requirements. While C-Si cells typically have an EPBT of 5 years or even up to 48 years, CIGS cells average only 1.7 years. Our company has achieved an impressive EPBT of just 1 year, thanks to our ongoing efforts to minimize resource consumption.
Despite our panels having a 25-year performance guarantee, they never become solar scrap, and neither do older or damaged models that cannot be sold. Instead, we give life to these solar panels through our Second Life programme, ensuring a lasting impact.
