Overview of This Portable Solar Panel Comparison Test
This video puts two portable solar panels head-to-head in real-world conditions: the ZOUW 230W bifacial panel and the Anker SOLIX PS200 200W panel. The tester conducts the evaluation on a clear mid-June day with ideal weather—around 75°F with full sun—to measure actual power output against manufacturer ratings. The setup is outdoors with standard camping and overlanding equipment, making this directly relevant to anyone powering their van or RV through solar.
This comparison speaks to van dwellers and overlanders who need to choose between portable panels without breaking the bank. The video focuses on practical concerns: weight, price-per-watt, shading performance, connector compatibility, and real-world efficiency. If you're building out a solar setup for off-grid travel, this test removes the guesswork about which panel actually delivers the watts it promises.
Key Moments
Key Moments in the Solar Panel Testing Process
- Setup and design features of the ZOUW 230W panel—trifold layout, kickstands on each section, lightweight aluminum frame, and included adapter cables
- Weight and price comparison between the two panels, with specs showing the ZOUW at 12 lb versus Anker at 16 lb, and a $100 price difference
- Full-sun power test showing the ZOUW producing 220 watts (95% of rated output) versus the Anker producing only 156 watts (78% of rated)
- Partial shading test demonstrating how the three panels are wired in parallel, allowing continued power output even when sections are blocked
- Physical comparison of build quality, noting the Anker's lack of kickstands on one panel and visible flexing in hot conditions

What to Know Before Choosing Between These Panels
- Test conditions: Testing occurred mid-June in clear skies at approximately 75°F, representing ideal summer solar conditions
- Power output reality: The ZOUW delivered 220W in full sun (nearly its full 230W rating), while the Anker produced 156W despite its 200W rating
- Shading performance: The ZOUW's parallel wiring means one or two panels can be shaded without losing all output; with two panels shaded, it still produced 125–126W
- Weight matters: The ZOUW weighs 12 lb compared to Anker's 16 lb—a meaningful difference if you're carrying panels regularly
- Connector compatibility: The ZOUW includes multiple adapter options (Anderson PowerPole, XT60, 5521 barrel, and others), making it compatible with most power stations
- Cost per watt: The ZOUW comes in at $1.20 per watt versus the Anker at $2 per watt, and includes a padded carrying case and extension cable
Frequently Asked Questions About These Portable Solar Panels
How does the ZOUW's bifacial design work?
Bifacial solar cells capture sunlight from both the front and back of the panel. The ZOUW uses the latest TopCon bifacial cells, which means light reflecting off the ground or a light-colored surface behind the panel contributes additional power output compared to single-sided panels.
What does "wired in parallel" mean for shading?
When panels are wired in parallel, each one operates independently. If shade covers one panel, the other panels still produce their full power. In series wiring, shading even one panel cuts the entire system's output to nearly zero. The video confirms the ZOUW uses parallel wiring, making it far more practical in camping situations where trees or vehicles might cast shadows.
Is 95% efficiency good for a solar panel?
Yes. Most portable panels lose 10–20% of their rated output in real-world conditions due to temperature, angle, and atmospheric factors. The ZOUW's 95% performance in full sun is excellent and shows TopCon cell technology lives up to its reputation.
Why does the Anker panel flex in the video?
The Anker uses a quad-fold design with only three kickstands instead of four. Without support on all sides, the panels droop slightly when standing upright, even in mild temperatures. The ZOUW's trifold design has kickstands on every panel, keeping the entire array rigid and properly angled.
Can I use either panel with my power station?
The ZOUW comes with a cable featuring multiple adapter connectors (Anderson PowerPole, XT60, 5521, and others), so compatibility depends more on your specific power station model. The video tests with an EcoFlow Delta 3 Plus. Check your station's input connector type before purchasing either panel.
