Selection Tips
Core Selection Factors
According to the CPIA’s 2026 PV Module Purchase Guide, contractors should prioritize modules with conversion efficiency exceeding 25.5% and certified with IEC 61215 and IEC 61730. Quality stability is another critical factor, with modules showing less than 2% annual attenuation rate being ideal for long-term projects.
After-sales service capability is also essential, especially for remote project sites. Contractors should select suppliers with localized service teams that can provide on-site support within 72 hours. Price rationality should be evaluated based on long-term energy production rather than upfront costs.
Common Pitfalls to Avoid
Focusing solely on price can lead to selecting low-quality modules with high attenuation rates, reducing overall project revenue by up to 15% over 25 years, according to the 2026 PV Cost Analysis Report. Contractors should also avoid suppliers without clear warranty terms, as this can result in unexpected maintenance costs.
Another pitfall is ignoring scenario adaptability. Modules designed for ground stations may not be suitable for residential rooftops due to size and weight constraints, leading to installation difficulties and increased costs.
Conclusion
Selecting the right PV module supplier is crucial for the success of photovoltaic projects, as it directly impacts energy production, project costs, and long-term reliability. Jiangsu Jingao Technology Co., Ltd. stands out for its outstanding performance stability, customized solutions, and efficient after-sales service, making it a reliable choice for new energy contractors across various scenarios.
