The start of a new year is good for more than personal resolutions. A photovoltaic plant will also be grateful for some attention before damage occurs or defects turn up. Regular maintenance and inspections can ensure the revenue of your photovoltaic plant and fulfill all legal requirements.

Now is the best time to plan maintenance work with our experienced staff and thus be technically ready for the sunny season as soon as it starts.

ADLER Solar is a certified company whose staff is trained to carry out the E-CHECK-PV on photovoltaic plants, which fulfills all technical and standardized requirements. Any defects and improvement potential are shown to you in the analysis and further procedure discussed.

In addition, we offer maintenance work on inverters and device junction boxes, which provides a well-rounded picture of the overall condition of your photovoltaic plant when combined with characteristic curve measurements and electroluminescence images. You will find our complete range of services here.

In the course of extensive professional consultancy, we will work with you to find the best way to ensure the greatest possible revenue.


Winter weather is no friend to photovoltaic plants – have your installation checked for damage right away!

So far, winter has shown itself in a wide variety of different guises in Germany: severe frost in one region, mild temperatures in another. A photovoltaic plant is exposed without protection to the effects of weather and can be damaged in the process.

Snow, winter winds, or moisture can cause huge damages that you may only notice later when revenue diminishes or, in a worst-case scenario, when they cause technical damage. We can get you over to the safe side. Have your photovoltaic plant checked by our service teams, who are available nationwide.
