Engineering office for photovoltaic expert reports and thermographic inspections

HaWe Engineering GmbH from Gauting near Munich offers you extensive know-how in the inspection and operation of your photovoltaic system – from rooftop systems to solar parks in the megawatt range. We create well-founded reports which are recognized in industry and science.

With thermographic measurements, we determine if your PV system performs as intended. The advantages of thermography also benefit industrial companies, building experts and insurance companies. Our certified employees also perform thermographic analyzes of electrical installations for you. In this way, safety-relevant defects can be detected and corrected immediately.
