Our history

A new chapter from 2026.

With the acquisition of DAS Kraftwerk GmbH in 2026, a new chapter begins. A community of investors and entrepreneurs with a combined 103 years of industry experience brings together the strengths of DAS Kraftwerk and Hartl Energy.

What has always distinguished DAS Kraftwerk remains: Austrian quality, technological innovation and the highest standards in development and production.

Under one brand

Six competencies, one system.

Today we unite capabilities that are usually spread across many trades – and turn them into holistic energy solutions for the most diverse fields of application.

01

Photovoltaics

From the classic rooftop system to the building-integrated facade.

02

Energy storage

Battery systems that decouple generation and consumption in time.

03

Electrical engineering

Distribution, protection and integration into existing infrastructure.

04

Facade construction

Design and installation built on decades of construction experience.

05

Mobile energy systems

Energy wherever no grid connection is available.

06

Research & development

In-house development as the basis of every product generation.

Innovation from Austria

Wiener Neustadt is the heart.

Our development and production site is the heart of the company. Since 2016 we have united research, development, prototyping, quality assurance and series production in one place. On more than 5,000 m² of production, assembly, warehouse and office space, we build PV modules in a wide range of sizes, outputs and designs – with a capacity of around 55 MWp per year.

Our technologies are created where research and practice work hand in hand. Decades of development work enable solutions that stand out for their efficiency, longevity and ease of integration.

Technology that creates new possibilities

Materials from aerospace.

Our roots lie in the development of innovative lightweight photovoltaics. The technology is based on years of research and development and was inspired by materials from aerospace engineering.

The result: ultra-light, flexible and exceptionally durable photovoltaic modules that have opened up new applications worldwide. Today this experience feeds into the development of modern complete systems – from classic rooftop installations to special solutions for industry, marine, critical infrastructure and mobile applications.

Ultra-light

A fraction of the weight of conventional glass modules.

Flexible

Follows curved surfaces instead of forcing them.

Durable

Designed for vibration, salt and continuous load.

Our fields of application

Wherever reliability matters.

Our energy solutions are used wherever reliability and efficiency are critical.
