For us, Real Value means that our products must deliver what they promise – over their entire service life. Our ’Made by SolarWorld‘ quality standards are based on the real-world conditions our modules will be exposed to over a period of 25 years. SolarWorld thus takes the decisive extra step in testing and assuring module quality – in a way that far exceeds industry standards. For our customers, this means: Real Value pays off over the long term.


With innovative PERC cell technology, we deliver even greater performance with the same module size – together with the same high quality standards for the materials used.
In this way, our customers receive a unique combination of proven quality and top technological performance.

Every new module generation follows our quality principle: Real Value lasts longer.


The combination of high quality and high performance delivers high energy yield reliably.
Our innovative Bisun modules increase the energy yield even more.

Reliable yields over the entire service life of the modules – an added value for our customers that pays off for at least 25 years!
