What components are included in photovoltaic installation
Photovoltaic installation components typically include the following core parts, which together form a complete photovoltaic power generation system:
1. Photovoltaic modules (solar panels)
The core power generation unit, categorized into types such as monocrystalline silicon, polycrystalline silicon, and thin-film batteries, is responsible for converting solar energy into direct current.
2. Support System
For securing photovoltaic modules, including rails, clamps, anchor bolts, etc., the appropriate structure must be selected based on the roof type (tiles, color steel tiles, flat roof) or ground installation scenario.
3. Inverter
Convert the direct current generated by photovoltaic modules into alternating current for household or grid use. It is categorized into types such as centralized, string, and micro inverters.
4. Distribution Box and Protection Devices
Including DC distribution boxes (with fuses and anti-reverse diodes) and AC distribution boxes (with leakage protection switches and circuit breakers), ensuring the safe operation of the system.
5. Cables and Connectors
Photovoltaic dedicated DC cables (UV-resistant, high-temperature resistant), MC4 connectors, for series connection between modules and connection to inverters.
6. Grid-connected equipment
For grid-connected systems, bidirectional meters and grid-connected cabinets must be installed, and local utility requirements must be met.
7. Monitoring System
Some systems include data collectors (such as Wi-Fi modules) for real-time monitoring of power generation and equipment status.
8. Auxiliary Materials
Waterproof sealant (roof waterproofing treatment), grounding wire (lightning protection), cable tray (cable routing and fixation), etc.
Additional notes
The off-grid system also requires energy storage equipment such as batteries and controllers.
The specific configuration should be adjusted based on the project scale (residential, commercial/industrial) and installation environment (roof, ground, BIPV).
