Frequently asked questions

If you receive a panel that is scratched or defective, please take photos right away and contact us. We'll help you sort out the next steps immediately.

The 200W rating is based on Standard Test Conditions (STC): 1000W/m² irradiance, 25°C cell temperature, and AM1.5 spectrum. In real-world use, actual output will vary depending on panel angle, temperature, shading, wiring losses, and device efficiency. Therefore, it is normal for the actual power to be below 200W.

The panel's rated wattage is measured under perfect lab conditions, so getting less power in real-world use is completely normal — your panel is working exactly as it should!

Solar panel performance can be affected by a number of factors. The most common ones are environmental—indirect sunlight, high temperatures, cloudy skies, and dirt or stains on the glass surface—all of which can reduce power output.

Each 200W panel has a Voc of around 23.06V. Wiring two in series gives you roughly 46.12V, which sits safely within the input range of most 60V power stations. This setup also allows the MPPT controller to operate more efficiently, delivering better power conversion and faster charging.

Yes, the 200W N-type 18BB bifacial solar panel works with most popular solar generators and battery systems. It features standard solar extension connectors, so it's easy to integrate into a wide range of solar setups.

When you look at the product page, you'll notice a title like "xxx Watt 12 Volt Solar Panel." The "12V" here isn't the panel's voltage (VOC or VMP)—it just means that a xxxW solar panel works well with a 12V system.

When we say "12V," we mean the panel is made for a 12V system that includes a charge controller. It's not the same as the panel's actual voltage output.

Yes. This panel is suitable for 12V systems, provided you have a compatible charge controller. Be sure to confirm your controller's input specs before you order.

When you wire panels in series, the voltage goes up but the current stays the same as one panel. Wire them in parallel and the current adds together while the voltage doesn't change. Both methods can help you get the most out of your power output.

Yes. It's easy to hook up extra panels in series or parallel whenever you want to grow your power system.

Not sure how many solar panels you need? First, check your power load in watts and your capacity in watt-hours. Choose a battery bank that meets your minimum capacity, then figure out how many panels you'll need to support it.

Your solar panel should be connected to a charge controller—to regulate the current—and to a battery to store the power. Use adapter kit cables to connect the panel and controller, then tray cables to hook up the battery.

To get your off-grid solar system up and running, you'll need a solar panel, a charge controller to keep the current in check, and a battery to store the power. Don't forget adapter kit cables to wire everything together and tray cables for your deep-cycle battery.

Simply put, "on-grid" means your solar panels are connected to the public power grid. "Off-grid" means your system isn't hooked up to the grid at all, so it saves the power it makes in a battery for when you need it.

No. You'll need to use this panel together with a compatible charge controller or solar generator—it regulates the power before sending it to your batteries or devices.

Nope, this panel doesn't include mounting hardware. But it fits most standard solar mounting systems—if you're wondering whether it'll work for your setup, just ask us!
