Performance in Real-World Conditions
You’ll want realistic expectations of what the panel will output in common conditions rather than ideal lab numbers. Here’s how it behaves in different light and temperature scenarios.
Peak Sunlight Output
In clear, direct sun with the panel angled optimally, you can approach the 200W peak for limited periods. You should expect peak values during the sunniest hours and when panels are cooler.
Typical Output in Good Conditions
Most of the time you’ll see actual output between 120W and 170W depending on sun intensity, angle, and temperature. That range represents what active users should assume when planning charging sessions.
Output in Partial Shade or Overcast
If clouds move in or partial shading occurs, outputs drop considerably and become inconsistent. You’ll want to minimize shade on any part of the panel because shading even a small area can disproportionately reduce power.
Effect of Angle and Temperature
You need to angle the panel toward the sun and avoid overheating to maintain good performance. The ETFE surface helps with light transmission, but high temperatures can still reduce efficiency, so occasional repositioning and airflow underneath the panel help.
Estimated Charging Times (Examples)
You’ll find the following examples helpful for planning. Actual times will vary with conditions:
- Charging a 500Wh power station: with ~160W average input it’ll take roughly 3–3.5 hours of solid sun.
- Charging a 1000Wh power station: with ~160W average input it’ll take about 6–7 hours of full sun.
- Charging a smartphone with PD60W: many phones will charge quickly via USB-C, often reaching 50% in 20–40 minutes depending on that phone’s charging curve.
- Charging a 60W laptop via PD: expect the panel to supply meaningful charge while you use the laptop; full charge time depends on laptop battery size and state.
Setup and Installation
You’ll find the setup straightforward, but a few steps make it faster and safer. Follow these tips to reduce fuss and maximize output.
Unfolding and Placing the Panel
Unfold the panel on a flat, stable surface, extend the magnetic handle, and secure the kickstands. You should point the panel toward the sun and adjust the angle for midday and morning/afternoon differences.
Using the MC4 Cable and DC Adapters
The included 9.8 ft MC4 cable gives you reach for flexible placement. Match the correct DC adapter to your power station input — the kit includes common adapters so you shouldn’t need extra connectors in most cases.
Direct USB Charging
If you want to charge phones, tablets, or a USB-C laptop, simply connect the device to the USB-C PD port or the QC3.0 USB-A using your normal cable. The built-in IC chip negotiates the charge current to protect your device.
