Why is the actual power output lower than 100W?

The rated 100W 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 100W is normal.

Can I connect multiple panels together?

Yes. Connect panels in parallel to increase current or in series to increase voltage. Make sure panels have the same voltage and specs. Use proper connectors and ensure your charge controller supports the total power.

What if I receive a scratched or defective panel?

Please contact our support team immediately. If the damage affects performance, we will work with you to resolve the issue promptly. We also recommend photographing the package and panel upon delivery for reference.

How should I clean or maintain the panel?

Use a soft cloth or sponge with water to wipe off dust, bird droppings, or stains. Avoid using harsh chemicals. Regular cleaning improves light absorption and helps maintain efficiency.

Is this panel compatible with my 12V system?

Yes, if your charge controller accepts a solar panel Voc of 26.02V or higher. Please confirm your controller’s specs before purchasing.

?N-Type Solar Cells, 25% Conversion Efficiency?The Callsun 2pcs 100 watt solar panel is built with advanced N-type solar cells delivering up to 25% conversion efficiency under ideal conditions, providing higher power output and more reliable performance than traditional P-type panels. Note: Actual power output depends on sunlight intensity, panel angle, temperature, and system compatibility.
?16BB Advanced Design for Longer Life? Compared to traditional 9BB/10BB designs, the 16BB solar panel utilizes advanced 16BB technology improves light absorption, reduces hot spot risks, and minimizes micro-cracks. This ensures superior performance and a longer service life, even in challenging environments.
?Compact & Flexible Installation (2 x 100W Panels)?Each 100W panel measures 31.1 x 22.7 x 1.1 inches and weighs only 11.4 lbs — about 15% smaller than traditional panels. Pre-drilled holes allow quick and secure mounting, making them ideal for RVs, boats, cabins, sheds, and off-grid systems. Please note this package includes two 100W solar panels and other accessories are not included.
?Enhanced Performance in High Temperatures? With a low temperature coefficient of -0.3%/K, the Callsun 200W high efficiency solar panel minimizes power loss and ensures consistent, reliable output even in extreme heat. Perfect for hot and sunny climates, it delivers stable energy production year-round.
?Built to Last & Smart Investment? Designed with low-iron tempered glass for maximum durability, corrosion-resistant aluminum alloy frames, and IP68 waterproof protection, this 100W solar panel easily withstands rain, snow, and extreme heat. Engineered for reliability, it boasts 2400 Pa wind resistance and 5400 Pa snow load capacity. It delivers powerful energy output for up to 30 years, making it a truly smart, long-term investment for sustainable power.
?10-Year Tech Support & 25-Year Performance Guarantee?We offer 10-year tech support for materials and workmanship, and a 25-year guarantee to maintain 84.5% output. If you have any problems with the solar panel 200 watt, please reach out to us!
