Understanding Solar Panel Technology in 2025

The solar panel industry has undergone significant transformation in recent years. With the emergence of TOPCon, HJT, and IBC cell technologies, buyers now have more options than ever before. This guide will help you navigate the landscape and make informed purchasing decisions.

Key Factors to Consider

1. Cell Technology

Modern solar panels primarily use three types of cell technology:

2. Power Output and Efficiency

For commercial projects, panels in the 550-700W range are now standard. Residential panels typically range from 400-450W. Higher efficiency means more power per square meter, reducing installation costs.

3. Warranty Terms

Look for manufacturers offering:

4. Certifications and Standards

Ensure panels meet international standards including IEC 61215, IEC 61730, and UL 1703. Additional certifications like salt mist corrosion (IEC 61701) and ammonia resistance (IEC 62716) are important for specific environments.
