Developing, designing, building and operating solar power plants and battery energy storage systems.

This is how we engage for a life-friendly future, powered by green energy.

With a team of around 200 employees, greentech is a leading expert in project development, plant design, technical consulting, construction, operational management and asset management of photovoltaic power plants and battery energy storage systems.

Our focus: to advance the urgently needed expansion of renewable energies, to operate power plants reliably and optimally, and to manage assets successfully. In this way, we make a measurable long-term contribution to the complete switch to green energy.

Greentech Partner for Financial Planning and Project Development
We are project developers for large-scale ground-mounted photovoltaic systems and battery energy storage systems (BESS) in Europe and develop projects from the initial idea through to implementation. In addition to identifying sites, carrying out approval procedures and the technical planning of the grid connection, the marketing of the electricity also plays a key role.

The projects are financed by the Group and in partnership with institutional investors.

02

Asset
Management

Invest with purpose – and help drive the energy transition forward.

At greentech, we act as a fully integrated asset manager, creating sustainable investment opportunities in photovoltaics and battery energy storage systems (BESS). Our combined PV and BESS portfolios bring together the acquisition of third-party assets with exclusive access to greentech’s proprietary project development pipeline. Leveraging our deep expertise in power marketing, we design tailored marketing and financing strategies that maximize long-term value. What’s more, we manage the operation of all assets in-house – ensuring maximum transparency, reliability, and hands-on stewardship of the portfolios entrusted to us.

03

Plant
Construction / EPC

We design and build PV power plants in the MW range in Germany.

The turnkey construction of PV plants includes engineering, procurement of components, construction and commissioning of the plant. We consider each location and each project individually and from the different perspectives and experiences of an integrated PV specialist.

This way we realise profitable and long-lasting solar power plant for the future.

04

PV
Operations

We take care of your investment.

With many years of experience and comprehensive technical expertise, we take over the technical and commercial management of photovoltaic plants.

We adapt our services modularly to your needs and structures. In this way, we individually design an optimal and cost-efficient service package for your plant. In every phase of operation, we are at your side with advice and support to ensure that your plant produces green electricity reliably for a long time.

05

Engineering
Services

When constructing new PV systems, a professional system design and the quality of the construction are the basis for a sustainable investment. During subsequent operation, it is also important to ensure high availability and the best possible performance of the system on a permanent and reliable basis.

From the initial site analysis to sound tender management and expert construction support to special inspections or later repowering – as a service provider or independent expert, our team of engineers and technicians offers comprehensible solutions and useful assistance for the benefit of your plant.
