Our Quality Promise
We want to supply our customers with high-quality products perfectly suited to their individual needs.
With enthusiasm for renewable energy, we enjoy coming to work each day to develop forward-looking and innovative solutions. We win over our customers through our guaranteed competence and quality.
GP Solar has been DIN EN ISO 9001 certified since the beginning of 2010, allowing us to consider the demands of our customers, legal guidelines, and environmental regulations. We have used these three factors to define and structure our internal processes, which we continuously optimize.
This ensures that our processes and workflows mesh smoothly.
Through constant improvement of our “GP Quality” we want to share our successful growth with our customers in the form of quality-control systems, which themselves are subject to rigorous controls.
