Adopting the industry-leading 9 busbars technology, this HQST 100W monocrystalline solar panel provides higher efficiency and longer service life. Grade A+ 166mm large mono solar cells offer 22-23% high efficiency and then generate more current. It's time to upgrade your conventional 5-busbar solar panels to these 9-busbar panels for better performance, reduced risk of cracks, and lower working temperatures.

Key Features

9 Busbars for Better Performance
The industry-leading 9 busbars technology reduces the risk of microcracks and provides longer service life than a conventional 5-busbar design. It can also reduce the working temperature by around 2℃ to improve the module's performance.

Built to Last
The IP65 rated junction box and solar connectors allow you to have no worries about water splashes and rain. Corrosion-resistant aluminum frame provides extended outdoor use that ensures the panel can last for decades. The 5400 Pa of heavy snow load and 2400 Pa of high wind provide excellent durability in a harsh environment.

1. How many kWh a day does this solar panel produce?

If your solar panels are exposed to 5 hours of direct sunlight per day, it can provide an average of 400-500 Watt-hours (0.4 kWh-0.5 kWh) of electricity (depending on sun availability).

2. Do these panels have pre-drilled holes on the back?
Yes, they have. The pre-drilled holes help you to install the solar panel quickly and securely.
3. Can this solar panel be adapted to a 12V Marine Battery or 48V Lithium Battery?

Yes, it can. The optimum operating voltage of this 100W solar panel is 20.4 V. So it's suitable to use for charging your 12V Marine Battery. As for a 48V Lithium Battery, you need to connect at least three solar panels in series. Please note that you need to connect the solar panel(s) to a Charge Controller supporting a 12V or 48V system.

4. How should I connect solar panels to my electrical circuit (series vs parallel)?

Solar panels can be connected in series or in parallel to meet your electrical circuit size and power demand. We recommend connecting solar panels with the same open-circuit voltage.

Connecting solar panels in series, the voltage (V) adds up, but the current (A) remains the same.

While connecting solar panels in parallel, the current (A) adds up, but the voltage (V) remains the same.

5. What do I need to have to complete my off-grid solar power system?

"Here’s a list of all the equipment required for a functioning off-grid solar system: Solar Panels, Solar Charge Controller, Inverter(s), Battery, Mounting and Racking System, Wiring Cables, and Fuses."
