About soventix

Soventix UK is part of the international PV systems group, Soventix GmbH (Soventix). Headquartered in Wesel, Germany. With subsidiaries in the UK, Romania, South Africa, Chile, Dominican Republic, Canada and the US, Soventix draws on its deep experience to plan, construct and operate valuable solar plants worldwide.

Soventix is increasingly active in the field of Independent Power Production (IPP) and develops innovative business models for Power Purchase Agreements (PPA) that provide businesses with an independent, green option for its electricity needs, and investors with stable, predictable cash flow.

In the UK the initial focus in 2011 was on the booming rooftop market. Having developed and built one of the larger rooftop portfolio in the UK, Soventix has expanded to encapsulate the full market up to 5MW.


PV systems and solar farms are an investment from which both the investor and the land-owner benefit. Each project promises a sustainable, cost-effective return for the consumer. If you would like to calculate your saving by converting to solar power please contact us directly at:
