FAQ: Professional Insight into Monocrystalline Solar Panel Technology

Q1. What is the main material used by a monocrystalline solar panel manufacturer?
A1. Monocrystalline solar panels use high-purity monocrystalline silicon ingots, grown via the Czochralski (CZ) process, offering fewer grain boundaries and higher efficiency compared to multicrystalline silicon.
Q2. What makes bifacial double glass modules superior?
A2. The bifacial design enables power generation from both panel faces. Double glass (front+back) provides better mechanical strength, enhanced salt-mist/ammonia resistance, longer lifespan, and higher fire rating (Class A).
Q3. What is meant by “module size” and why does it matter?
A3. Module size refers to the panel’s physical dimensions (e.g., 2384×1303mm). Custom sizes allow adaptation to various installation spaces, load constraints, and can optimize system layout for maximum yield.
Q4. How are monocrystalline panels tested for quality assurance?
A4. Every batch is subject to EL (electroluminescence) scans (detecting microcracks), IV curve measurement, high/low temp cycling, damp heat (>1,000 hrs), and mechanical load simulation (IEC 61215/61730 standards).
Q5. What industry certifications should a quality monocrystalline solar panel supplier have?
A5. The essential certifications include ISO 9001 (Quality Mgt), ISO 14001 (Environmental), IEC 61215/61730 (module reliability and safety), and regional marks such as CE, UL, or TÜV.
Q6. What is the typical delivery timeline for custom modules?
A6. Standard modules: 18-25 days after order. Custom modules: 3-5 weeks depending on BOM and order size. Airfreight is available for urgent needs.
Q7. What’s the difference in annual degradation between N-Type and P-Type panels?
A7. N-Type panels show ≤0.4% annual power loss, while P-Type monocrystalline usually see 0.5%–0.7%. Over 30 years, this translates to >3.5% higher output retention for N-Type modules.
