FAQ

Q: What is the difference between Mono and Flexible solar panels?

A: Monocrystalline solar panels are high-efficiency rigid modules, while flexible solar panels are lightweight and suitable for curved or special installation surfaces.

Q: Can solar panels be used with battery storage systems?

A: Yes. Our solar photovoltaic modules are compatible with hybrid solar energy storage systems.

Q: Which solar panel is best for commercial projects?

A: High-efficiency mono solar panels are commonly used in commercial and industrial solar power systems.

Q: Are foldable solar panels suitable for permanent installation?

A: No. Foldable solar panels are designed for portable and temporary off-grid applications.

Q: Do you support bulk solar panel supply?

A: Yes. We support OEM production and bulk supply for EPC and wholesale solar projects.

Q: What is the typical lifespan of solar panels in commercial projects?

A: In standard operating conditions, solar panels are generally designed for 25 years or more of service life. Actual performance depends on installation quality, maintenance level, and environmental exposure.

Q: Can different wattage solar panels be used within the same system?

A: Technically, it is possible, but not recommended for large-scale commercial systems. Mixing different wattages may affect system efficiency and MPPT tracking performance, so a uniform configuration is preferred for stable output.

Q: What should be confirmed before ordering solar panels for a project?

A: Key factors include installation space, system voltage design, inverter compatibility, and total project capacity. These parameters help ensure correct module selection and reduce mismatch risk during system integration.

Q: Do solar panels require regular maintenance after installation?

A: Maintenance requirements are relatively low. Regular surface cleaning and periodic electrical inspection are usually sufficient to ensure stable performance over long-term operation.
