1. Overview

Photovoltaic (PV) connectors are specialized electrical components designed to safely and efficiently interconnect solar panels and associated power systems. These connectors enable rapid, reliable connections in photovoltaic arrays while meeting stringent requirements for environmental resistance, electrical performance, and mechanical durability. As critical elements in solar energy systems, PV connectors ensure optimal power transmission and system longevity in residential, commercial, and utility-scale installations.

2. Main Types & Functional Classification

3. Structure & Components

Typical PV connector assemblies consist of: - Contact Elements: Electrolytic copper with silver-plated surface for low resistance - Insulation: High-temperature resistant thermoplastic elastomers (TPE) - Housing: UV-stabilized polycarbonate with IP67+ protection - Cable Gland: Strain relief mechanism with 50N pull-out resistance - Locking System: Push-pull or screw-type mechanical interlock
