Why solar connectors? Because connectors usually don’t get the attention they deserve. They are a key component of a solar system and hold an important function: to provide a low-resistance connection between solar modules and other components while maintaining their integrity under extreme weather conditions for more than 25 years. Crazy, right? A piece of…

Helping solar project stakeholders understand the root causes of PV system fires and prevent thermal events. Fires in PV systems are rare, but they have severe consequences for safety and property damage. When videos of fires go viral, like one shown here, they damage solar power’s reputation. They’re a threat to our clean energy transition.It’s…
