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.

Call Sun N-Type Panels Demolish the Competition!!
A+++++ Call Sun N-Type Panels use the highest quality components, with unbelievable craftsmanship, durability, attention to detail, highest efficiency, higher power output, and a 25 Year Warranty. If you want the absolute best for this price point Call Sun is definitely Top Tier punching way above their specs and price point. I love the exceptionally high quality of Renogy & BougeRv Solar Equipment, but when it comes to the Solar Panels these Call Sun Brand N-Type Panels demolish the competition. The Call Sun N-Type Panels are conservatively underrated in their performance, these panels exceed their specs while remaining within the safety margin. 125% output in full direct sunlight and 92-95+% output even in shaded areas these N-Type Panels pull ahead of the P-Type panels by a vast margin in performance. You can pay more for a brand, but you won’t find a better set of N-Type Panels with better quality, performance, and durability. Call Sun also had excellent customer service representatives who are extremely professional, knowledgeable and go above and beyond to ensure their products meet or exceed customer satisfaction.. Thank you for supporting America and it’s Armed Forces!!

Small but mighty!
These panels have surprised me. I bought these as I have limited space to accommodate solar panels. If you have more area, maybe look at a larger panels with more output. That said… I have 8 panels installed. During the middle of the day I am seeing around 820 -830 watts of output. I am getting full output from these panels. Very impressive. I highly recommend these for tight quarters. Build quality is good and panels are lightweight and easy to handle/install.

Works great!
Very nice solar panel and great customer support. Has good output power.

Nice panels, solid construction, compact, would recommend.
I bought these panels to add an additional string to my DIY home solar system which currently consists of 36 100W panels connected to two Pecron E3600LFP units each having two additional Pecron EP3000 batteries attached. We also will use the Callsun panels for camping. Today, 9/25/2025 at 12:26PM under clear sunny conditions at latitude 36.0039 North at around 72 degrees F., a string of 6 of these panels was producing 503 watts. This is about 84% of rated output under optimal conditions. The 6 panels are connected as 3S2P (3 panels in series connected in parallel with another 3 panels in series), and were producing 9.2 amps at 54.7 volts DC. Photos are attached.The rest of the panels in this system consist of 24 Harbor Freight #57325 and 6 HGST 100W monocrystalline panels. The output of the 6 Callsun panels under sunny conditions are approximately equal to the other 6-panel strings in my system, while being more compact. These panels measure 31.1 x 22.7 inches (706 sq. in.) as compared to the Harbor Freight panels which measure 36.5 x 27 (985.5 sq. in.) while producing about the same output. The only rigid-frame 100W panels that I have seen that come with built-in support legs are the Harbor Freight #57325. I wish other panels such as these Callsun panels came with such built-in legs. In this case, I used a U-shaped structure of 1/2″ PVC pipe attached to each Callsun panel to support it at about a 30 degree angle.I like the panels and would recommend them, particularly for portable use due to their compact size while producing equivalent output to larger 100W panels. These are the 16 busbar (BB) design and my other panels are 5BB. I have not tried to compare outputs with various levels of shading on the these two types of panels to assess the purported advantage of 16BB.

Perfect for cartop use in mobile solar office
I replaced a huge unwieldy 100 watt older solar panel with these much more efficient smaller panels set crosswise across the roof of my Toyota Corollaâmore than DOUBLING the power output of the SAME ROOF SPACE.They are much more efficient and can work in partial shade much better and I added an MPPT controller and direct DC to DC converters for the exact voltage and amps for my laptop and USB connections instead of a power inverter to AC and then having to convert back down to DC which is highly inefficient. I also added a 100ah lipo4 battery.All told, these conversions gave me 5 days of power for my office from one day of sun instead of 1 day. All of it cost less than 400.00!!! (Battery, panels, MPPT controller) And what made it possible was these new smaller new technology solar panels.One extremely important benefit is that they are easy to stow. They fit in the trunk MUCH BETTER. Even if I have stuff in the trunk they easily slide on top and I put a single piece of cardboard between them to protect them. The larger 100 watt panel I used to use was a real headache to finagle into the Corolla trunk! If there was anything in the trunk it lifted the panel up to where the arms of the trunk support come down potentially cracking and ruining the panel. So remember that if you just measure the trunk width to see if a panel will fit!Whatever your car is, measure BETWEEN THE TRUNK HINGE SUPPORTS that come down when you close the trunk!These panels are BEYOND PERFECT for maximizing the power available on a single small car top!! While still being stow-able. LIFE-changingâ¦Thank you for making my life much easier and allowing me to work from my car office!! Much love to you!
