Our values




SINCE 2001








Sustainable Manufacturing of Solar Modules made in Germany.

Our central claim is the sustainable production of solar modules. Heckert Solar was already certified according to ISO 14001: 2015 on the subject of environmental management in 2018. The careful and responsible use of resources is very important to us.

Did you know that Heckert Solar …

– reduces CO2 emissions with the “Made in Germany” PV modules
– produces exclusively with electricity from own PV plants
– and additionally purchases green electricity
– uses waste heat for the heating of its offices
– has been certified for the sustainable production of solar modules
– a strict waste separation is implemented in the entire company
– has converted the own test PV plant into a biotope solar park
– covers a large part of their water consumption through rainwater
– cute sheeps are taking care of the mowing of the solar park

20 Jahre Solarmodule Made in Germany. Von 2003 bis 2023. Qualität die bleibt!


Made in Germany.

We produce exclusively in Germany. The first Heckert solar module was manufactured in September 2003 and one was proud of the 6 MW annual production capacity. 20 years later, Heckert Solar disposes of a manufacturing capacity of 800 MWp per year. Both the traditional main quarter in Chemnitz and the 2021 inaugurated manufacturing plant in Langenwetzendorf in Thuringia can count on highly qualified, well-practised teams as well as on the latest and highly automated assembly lines. It is from here that we can best fulfil our own standards in respect of quality, timeliness and ability to deliver.

Have a look for yourself!


Quality that lasts.

We work solely with certified materials from leading manufacturers. All modules are supplied with greater output than stated and are VDE-certified – including construction type and safety certificate, salt spray corrosion test and tests for ammonia resistance. Every module bears the CE mark (Conformité Européenne). We supply the NeMo® range with a standard 15-year product warranty, and a performance guarantee of 90% for 10 years and 80% for 25 years. Upon request, we deliver directly to your construction site. For even more flexibility, we also do not specify any minimum purchase quantities.

We count on the advantages of the latest technologies and smart ideas. We have designed our own hollow chamber profile for the particularly torsion-resistant module frame. We use high-tech aluminium alloy which lasts for many summers and winters. An innovative two-component adhesive technology connects the frame reliably with the laminate. Together with the highly transparent, anti-reflective ESG solar glass, we can assure you a resilience that goes far beyond the usual.


Put your trust in us.

You can also rely on constant “outstanding business strength” and especial financial stability. Since 2011, both have been regularly honoured by top rating certificates – currently by the Creditreform agency. We have been continuously awarded top rating certificates since 2011.

Together we are strong.

By founding the Heckert Solar, Wattkraft, Interfloat consortium, we have combined several decades of production and sales know-how. Together we want to reaffirm our commitment to Germany as a business location in the heart of Europe.

We as Heckert Solar have been producing solar modules exclusively in Germany for 20 years and we want to continue to do this independently, sustainably and with the latest technologies. This requires strong partnerships that can be relied on in the long term. The common goal of Heckert Solar, Wattkraft and Interfloat is to map at least 90% of the value chain in the production of a solar module from polysilicon to cell production to the final solar module at production sites in Germany.

As part of the consortium, all three associated companies increase their efficiency in their own production and create a high degree of stability. The carefully coordinated production processes will result in an even higher product quality for our customers. In addition, the consortium helps to secure the development of the latest solar technologies in Europe and is thus a substantial contribution for the security of supply with renewable energies as regards the energy transition in Europe!
