About Us

Your PV wholesaler in the north

As a craft business and especially installation company in the photovoltaic branch you are more than ever in a gap between the end customer, whole sale, technical development, price calculation, energy politic, subvention, complaints, marketing activities, internal workshops and last but not least the professional installation on site. In these sophisticated times it is even more important to rely on a strong partner in all business fields. This includes quick response time, excellent credit ranking, uncomplicated order processing as well as an open mind for customers’ requirements and market demands.
