Photovoltaic junction boxes are crucial components in PV modules for connection and protection. Integrated ones have a simple structure with one box housing diodes and cables, offering low - cost and easy installation. However, they face heat - dissipation and resistance issues in high - power applications. Split - type junction boxes consist of multiple boxes, each with one diode and separated positive/negative cables. They have excellent heat - dissipation, can boost module power and reduce cable usage, yet are costlier and require more complex installation. The former suits small - scale distributed projects, while the latter is more suitable for large - scale ground - mounted power plants.

How does solar power work？As a new energy solar pv power technology is a technology that directly converts solar energy into electrical cenergy. The components of pv modules you will see below: 1. Solar cell 2. Solar glass 3. Solar EVA film 4. Solar Alu frame Each part is an important role for solar panles.
