Products Description
For project developers and long-term asset owners, a solar module's warranty is the ultimate measure of financial security. The JA Solar n-type double glass modules is backed by an exceptional dual warranty structure that directly protects your Levelized Cost of Energy (LCOE) and long-term energy yields:
12-Year Product Warranty: Covers materials and workmanship, ensuring the physical integrity of the module under diverse operational conditions.
Bifacial double glass solar panels degradation rate over 30 years: Guarantees that the module will maintain a high percentage of its nominal power output over three decades.
This reliable power retention curve ensures that your utility-scale or commercial installation continues to generate high yields and consistent cash flow decadal-wide.
FAQ
Q: What are the exact degradation guarantees for this n-type double glass module compared to traditional p-type PERC modules?
A: Our n-type Bycium+ cell technology offers significantly better degradation profiles. It guarantees a 1st-year degradation of 1% (compared to 2% for p-type) and an annual degradation of 0.4% over 30 years (compared to 0.45%-0.55% for p-type).
Q: Do these modules carry the necessary CE certification for European grid connection?
A: Yes. The modules are fully CE certified and meet all European Union safety, health, and environmental standards, ensuring smooth customs clearance and compliance for projects in Italy and other EU countries.
Q: Do you hold KS certification for the South Korean market?
A: Yes, the modules are KS C 8561 certified solar panels. This ensures full compliance with South Korean industrial standards and eligibility for local public and commercial tenders.
Q: What is the fire safety rating of this double glass module?
A: The module is certified as UL Type 29 / Class C Fire rated. The dual-glass structure (2.0mm front and 2.0mm back glass) provides superior fire resistance, making it highly suitable for strict C&I rooftop safety requirements.
Q: How do you protect the modules from Micro-cracks during long-distance maritime transport?
A: We use reinforced vertical packaging (36 pcs/pallet) with heavy-duty corner protectors and high-tension strapping to prevent module shifting.
