Product Description

Friendly Reminder:

For parallel or series use, please connect only panels of the same brand and model. Mixing different types may cause voltage/current mismatch and reduce system performance.

Note: 200W is based on STC (1000W/m², 25°C, 1.5AM). In real use, angle, temperature, shading, wiring, and device efficiency affect output. So actual power below 200W is normal.

Tip: For best results, face the panel toward the sun—usually south in the U.S.—with a tilt angle near your local latitude. Seasonal angle adjustment can boost output.

Note: Solar meters offer more accurate panel readings. Power stations are handy but may show lower output due to efficiency loss, cable length, or battery level.

Why is the actual power output lower than 200W?

The rated 200W is based on Standard Test Conditions (STC): 1000W/m² irradiance, 25°C, and 1.5 air mass. In real use, panel angle, temperature, shading, wiring loss, and device efficiency affect output. So, actual power below 200W is normal.

Can I connect multiple panels together?

Yes, you can connect multiple panels in series or parallel.

Important:For best results, use panels of the same brand, model, and specs. Mixing different types may cause voltage/current mismatch and reduce efficiency.

What if I receive a scratched or defective panel?

If you receive a scratched or defective panel, please take photos immediately and contact our support team. We will assist you with the next steps promptly.

Can this panel be used with different solar generators or battery systems?

Yes, the 200W N-type 16BB bifacial solar panel is compatible with most popular solar generators and battery systems. It comes equipped with standard solar extension connectors, making it easy to integrate with a wide range of solar power setups.

What is the meaning of 12V in the product title，Why is this value different from the voltage of the solar panel？

When you open the product page, you will see a title like "xxx Watt 12 Volt Solar Panel". The "12V" here does not refer to the voltage of this solar panel (VOC or VMP), but to the fact that one xxxW solar panel is suitable for 12V system.

【N-Type Solar Panel with 25% High Efficiency】The Callsun 200 watt solar panel is built with advanced N-type solar cells, delivering an impressive 25% conversion efficiency. Compared to traditional P-type cells (which max out at around 23.5%), N-type technology provides higher efficiency and greater power output — giving you more clean energy from the same panel size.
【Boost Your Power with Bifacial Technology】Callsun 400W bifacial solar panels feature a transparent backsheet that captures sunlight from both sides — direct, reflected, and diffuse rays alike. Unlike traditional panels with opaque backs, our bifacial design harnesses extra solar energy from the rear, increasing your total power output by up to 30%. Get more clean energy and maximize your solar system’s efficiency with Callsun.
【Advanced 16BB Cell Technology for Enhanced Reliability】The Callsun 16BB solar panel 400 watts adopts cutting-edge 16BB solar cell technology, delivering higher photoelectric conversion efficiency while effectively reducing hot spots and hidden cracks. Enjoy superior module performance and a longer service life, so you can generate more power with greater reliability — year after year.
【Perfect Fit for Class B Vans & Easy Installation】Measuring 51.3 x 30.3 x 1.4 inches and weighing just 23.8 lbs, this 200 watt solar panel is designed to maximize power in a compact footprint — ideal for Class B vans and other tight rooftop spaces. Each panel features pre-drilled holes on the back for quick, hassle-free mounting on large rail mounts or other surfaces, making installation faster and more secure.
【Built to Last Decades Longer】Engineered to handle harsh weather year after year, the Callsun 200W monocrystalline solar panel uses ultra-strong tempered glass, corrosion-resistant aluminum, and IP68 waterproof technology. With an impressive lifespan of up to 30 years — 5 years longer than most standard panels — you’ll enjoy more free energy, more savings, and true peace of mind for decades to come.
