Q&A

Q1: Why is your panel rated 200W while some similar-size panels claim 300W, 500W or 600W?

A: Solar panel power depends on actual panel size, cell efficiency and sunlight conditions. A panel must have enough surface area to produce high wattage. Our panel is honestly rated at 200W with real electrical specifications under Standard Test Conditions.

Q2: Will the panel always output full 200W?

A: The 200W rating is measured under Standard Test Conditions. Actual output may vary depending on sunlight intensity, sun angle, temperature, shading, wiring, controller efficiency and battery condition.

Q3: How should I compare different solar panels?

A: Please compare the actual dimensions, rated power, Pmax, Vmp, Imp, Voc, Isc, cell type and warranty. Wattage alone may be misleading if the panel size and electrical specifications are not realistic.

Q4: Is this a real 200W solar panel?

A: Yes. This is a true rated 200W solar panel. We provide the actual dimensions and electrical specifications so buyers can verify the rating before purchase.

Q5: Should I wire panels in series or parallel?

A：Series wiring increases voltage.
Parallel wiring increases current and can reduce the impact of partial shading.

Always match your panel configuration to the specifications of your charge controller or inverter.

Q6: What’s the difference between off-grid and on-grid solar systems?

A：Off-grid systems operate independently from the utility grid and typically use batteries for energy storage.
On-grid systems connect to the utility grid, allowing solar use with grid backup when needed.

Q7: Why is my solar panel producing less power than expected?

A：Output may be reduced by:

• Partial shading

• Cloudy weather

• Dust or dirt buildup

• Incorrect installation angle

• Wiring or connection issues

Regular cleaning and routine maintenance can help improve performance.

Compared with standard 12V panels, this 18V solar panel works more efficiently with a controller to charge a 12V battery using a single panel.

The higher-voltage design simplifies installation and reduces system complexity.

Full-Welded, Long Reliability

Built with full-welded solar cell technology, this panel helps reduce hotspots for improved safety, stability, and long-term performance.

Designed for durability, it provides reliable output for 30+ years.

Pure Copper Wiring

Upgraded with pure copper wire, this panel delivers more stable electrical performance in high-temperature conditions than panels using copper-clad aluminum cables.

Pure copper runs cooler and carries current more efficiently, helping maintain steady output in hot weather.

Premium Build Quality

Made to a higher standard, this panel reflects careful engineering, precise assembly, and dependable craftsmanship.

The result is reliable performance with a clean, professional finish.

Dual-Layer Cable Protection

For added outdoor durability, the cable features a dual-layer protective design:

• UV-resistant outer jacket
• Inner insulation layer

This reinforced structure helps withstand sun, weather, and long-term outdoor use.

Safety-Focused Design

A reverse current blocking diode junction box helps prevent battery drain at night.

The tempered glass is securely sealed to the frame to resist moisture, dust, and environmental wear, while smooth finished edges allow safer handling during installation.

Secure Packaging

Each panel is carefully packaged to help protect it during shipping and ensure it arrives in excellent condition.
