Review: Powerful 150 watt ETFE solar panel

Powerful 150 watt ETFE solar panel. Good solar panel even with partial shading. Partial shade brings a complete drop in performance for many solar panels - yet here there is still good performance left. Perfect for touring vehicles, the camper and for vanlife! Semi-flexible solar panel with top marks in various weather conditions. Whether for the cottage, RV, or overlanding, this solar panel shines not only in terms of price!

As you surely know, I regularly test what the currently available solar panels are good for. Recently I also wrote a buying guide.

Last week I bought a new ETFE solar panel with 150 Watt, for a deeper test. Again, I wanted a lightweight flexible solar panel to charge my Ecoflow battery boxes outside of travel. My solar panels had all migrated to my brother, who knew how to use them better in everyday life.

I went with a new supplier - and I'm still amazed at the quality of the product. The packaging already promised a lot - even a very rough handling of the package could not lead to any damage there.

With high-quality detailiebe was implemented inside the box even edge protectors / kink protection. This is absolutely necessary, because this semi-flexible ETFE solar panel looks extremely filigree. It is almost excessively flexible and thus suitable for a fixed installation.

Key data:
1190 x 670 x 2 mm, weight 2.6kg
150 Watt, EFTE coating
8.26a max amps, 18.15v max volts, 21.45 voc, 8.76a lsc

The ETFE coating is incredibly fine-pore and optically only visible up close. From a distance you can't even see that it is a solar panel - everything is hidden under the ETFE film.

The measured power at the Ecoflow box is quite impressive, I tried to visualize it in the uploaded pictures.

overcast, rainy, 19w
cloudy, 48w
partly shaded, sunny morning 53w
sunny, partly shaded 96w
sunny, about 70% shade 26w

I did different tests in complete cloudiness, light rain, sunny days, with partial shading etc. And the solar panel really delivered consistently great performance, sometimes outperforming my 390 watt Büttner solar system installed in the bus.

In terms of performance, I can only give a clear buy recommendation, at the same time the solar panel also shines with a crisp price: ETFE semiflexible Solarpanel 150 Watt

How good the workmanship or the quality of the materials in terms of UV long-term protection is, that we will unfortunately only see over the years.

The tests were carried out using the Ecoflow River Mini and the Ecoflow River Pro and the Ecoflow App.

I hope this somewhat unusual type of performance visualization with picture-in-picture pleases you readers and helps you in the assessment of the solar panel.
