HOTSPOTS & DIODE FAILURE · INGRESS & CORROSION · CONNECTOR RESISTANCE
A solar panel is only as reliable as its junction box.
A solar panel is only as reliable as its junction box.
Three risks that compromise panel performance over a 25-year operating life.
Substandard bypass diodes can overheat under partial shading conditions, creating hotspots that damage solar cells and significantly reduce module lifespan. Poor sealing allows moisture and contaminants to enter the junction box, leading to corrosion, ground faults, and premature system failures. At the same time, loose or low-quality terminals increase contact resistance, causing power losses, reduced efficiency, and a higher risk of electrical arcing across large scale installations.

TÜV Rheinland is the world's most recognised third-party PV certifier.
IEC 62790 specifies safety requirements and tests for junction boxes used on photovoltaic modules. TÜV Rheinland verifies that our products meet every clause — from impact resistance and IP65 / IP68 sealing to thermal cycling and partial discharge — so module manufacturers can specify Sollean with confidence and pass their own bankability audits.
