In the rapidly evolving world of solar energy, ensuring the safety of photovoltaic installations is crucial. Beyond standard components such as solar panels, inverters, and mounting structures, it is essential to understand the complementary safety equipment necessary for safe operation. This article explores these vital equipments, focusing on safety standards specific to Europe and the United States.
Main Components and Their Role in Safety
Standard photovoltaic installations consist of solar panels that generate electricity, inverters that convert this energy into usable current, and mounting structures that ensure stability. Additionally, the protection cabinet plays a crucial role in protecting against electrical hazards such as fires and electrocution.
Complementary Safety Equipment
In addition to basic components, additional safety devices are necessary for a secure photovoltaic installation:
- DC Disconnectors: These devices allow the current to be safely cut off for maintenance.
- Switch-disconnectors: Must be installed on both alternating current (AC) and direct current (DC) sides of the inverter to allow safe interventions.
Safety Standards in Europe
In Europe, the UTE C15-712-1/2/3 standard sets safety criteria for photovoltaic installations, encompassing everything from sizing to maintenance, including electrical protections and network connection. Installations must also follow EN 62446, which dictates the minimum requirements for documentation, installation, and testing.
Safety Standards in the United States
In the United States, the National Electrical Code (NEC), particularly Article 690, determines the safety standards for photovoltaic systems. It includes specifications on wiring, grounding, and protection against overcurrents. The equipment used must also comply with UL standards, such as UL 1703 for modules and UL 1741 for inverters.
Safe Installation and Maintenance
Compliance with standards is critical not only for safety but also for the efficiency of the installation. Proper installation and regular maintenance are essential to ensure the safety and performance of the system in the long term.
The safety of photovoltaic installations goes beyond the installation of basic components. Complementary safety equipment is crucial for compliance with regional standards and for the protection of people and property. It is strongly advised to work with qualified professionals for the design, installation, and maintenance of photovoltaic systems.
