Impressed 👏
Im impressed with its performance, I've got it attached to my Bluetti power bank via a 4m extension cable on a cloudy/sunny day and when the suns out its giving me between 130 and 177w.When the sun goes in (totally, behind a thick grey cloud), the lowest power delivery has been 30w so far.It seems of fairly good quality build, eyelets are smaller than I'd hoped.It fits in the side of the van for storage which is fab, I can set it up and move it on my own which is great (disabled). Just wish those eyelets were bigger so we could make a decent handle for it/ hang it from carabiners.Overall I'm impressed, good value 😀

Absolutely perfect, well packaged, excellent quality.
Purchased 180w to mount on the roof of my camper to replace 2x40w ones. Even on a cloudy day the output is impressive. I can now run my compressor cool box 24 hrs without draining my 2x110Ah batteries, plus spare power for tv, lights and mobile phone chargers.

180W panel is 1260mm long, not 1200mm
I bought the 180W panel to go on my campervan. The panel works well but it came at 1260mm long and not the 1200mm length it says on the image showing the sizes. This caused me a problem as the ends didn’t fit on the raised panels of my roof but I managed to work around it.

Excellent panel
Really decent flexible solar panel. Feels quite robust. I’ve seen a peak of 187W charging my Delta 2 so it’s stated wattage is accurate. Produces around 40W in cloudy conditions, 100-150W in mixed sun and cloud.

Firefly Energy 400watt solar panels
The media could not be loaded. I have to say I wish I had bought these firefly energy flexible 200watt solar panels sooner. Even on a rainy day with cloudy weather they are charging a 24volt 200ah lithium batteries. Very happy indeed and a great price and value for the money

Working well
Had it fitted to my caravan now for four days it's the best solution yet but time will tell the right size it the mm/cm not inches (150w)
