Since April 2008, ADLER Solar has been supporting the European solar industry as a leading full-service provider with photovoltaic concepts for plant construction, quality assurance, performance optimisation and sustainable energy strategies.


Over the last 10 years we have progressed from an independent service provider to a recognised expert for smart energy solutions. Our comprehensive service portfolio ranges from PV Plant Construction, Repowering, Engineering Consulting and Operations & Maintenanceto storage, electromobility and LED solutions. In figures, this means: over 5 million processed modules, more than 100 supervised technical due diligence procedures and 200 MWp implemented in the area of plant construction and optimisation.


In addition, our service portfolio includes After-Sales, Inverters, Test & Repair as well as Claim Management. Headquartered in Bremen, we manage another location in Waldkraiburg/Munich.


As a long-standing PV expert, we advise commercial and industrial companies on all aspects of solar energy. In other words: we see ourselves as your partner for a proactive energy turnaround, among other things regarding:


  • PV plant construction to reduce operating costs or as an investment – entire project management from individual consulting to planning, implementation and commissioning from a single source
  • Repowering for older solar systems ­– investment protection through targeted optimisation measures over the remaining lifetime of your PV system
  • Comprehensive consulting for sustainable energy concepts – including storage solutions for electricity/heat supply through locally generated solar energy, charging stations for electromobility and energy-saving LED lighting systems
