We are Your experts in photovoltaics

We, the Solarzentrum Stuttgart, have our roots in research at the University of Stuttgart. We install and inspect your PV system. We install and inspect your PV system, are technically orientated, have an eye for detail and value quality in components and execution.

Our services and products

Photovoltaic Inspection

We inspect your PV system for performance, installation defects and hidden faults.

Damage recognition

Hail damage, transport damage, manufacturing or installation defects. With experience, performance measurement, thermal imaging and our patented DaySy EL process, we recognise even the smallest defects and can identify the cause.

Expert report

Our expert reports document the location, type and, if possible, the cause of the recognised defects. In the event of hail damage, our reports are covered by many insurance companies.

Electroluminescence by daylight

Our DaySy EL process allows us to inspect your PV system without the need for complicated set-ups during the day. While inspecting, we create high-resolution EL images of each PV module, which provide information about the degree of damage and its cause.

Luminescence in daylight

Our patented DaySy process allows luminescence inspections of PV modules in their installed state in full daylight. Disassembly of the modules or complex set-ups and containers are a matter of the past.

EL: Electroluminescence

For electroluminescence (EL), a power source energises individual modules or entire PV strings as required and the DaySy camera generates high-resolution EL defect images. Individual modules on delivery, entire strings on acceptance, random samples or even 100% inspection are imaged quickly and efficiently.

PL: Photoluminescence

With photoluminescence (PL) measurement, the necessary energy comes from the sun. A major advantage over EL is that no power source is required for the inspection. Our DaySy camera detects the same defects as EL, but some defect types are less pronounced.

Photovoltaic Installation

We install your customised photovoltaic system for your own home.

Profound knowledge

Our experience as researchers and experts is the basis for your individualised PV system at the highest standard. Our view is always technical - ‘through engineering eyes’, so to speak - and we focus on high quality.
