ET-Solar 420W Monocrystalline Solar Panel 120 Half-Cut Cells All Black Frame

I had initially ordered a 330w panel due to their low price from this retailer, but TNT delivery decided to mess up the delivery. The retailer came through and sent me the 345w version (slightly bigger for 15w increase). Took a few days before I could test it properly as the weather was sodden and soaking.I needed this for my Bluetti eb150 powerpack. Its currently whacking out a respectable 200w in the late Autumn/early Winter sun, and as you can see from the image it did peak at 300w now and again.The construct is pretty good. It doesnt feel as sturdy as more expensive panels as the frame is more low profile, but if you're gentle when moving it and mount it properly somewhere it should be absolutely fine. The actual glass and solar cells look really good though,as good as more expensive panels.If you have space, for this price buy one.

Let me start by saying that this is a big panel. A very big panel and comes in at 18kg. But! It seems to work well. I can get nearly 200w on a clear, bright day in November so I have great expectations for the summer months.Arrived with a few scrapes on the side of the panel body but nothing that affects the performance of the panel.Overall a great wee device and I look forward to getting another one soon.

Delivery took 5 weeks and was expensive. When I contacted seller they told me they would give me a free gift as the delivery was weeks longer than stated on order, this never arrived. Sold with stand, stand does not fit. Poor service from seller.

Disappointed in these panels, took a risk as they seemed cheap compared to similar high wattage solar panels. Significant drop in performance in the hot sunny weather and half cut cells seems to impart little advantage when in partial shade. The cables are only just long enough to connect to each other and one connector has overheated and melted. I still don't know why.

Bought two to give me 840w. This is running through an old Outback Flexmax into 4 Rolls batteries giving 450ah @24v.Peak output on a sunny day just shy of 700w - I'm happy with that for England and the panel angle. Generally around 120-160w on a cloudy day. Winter will be the challenge. Good value.

Not had a full sunny day yet but it performs well under shady skies and shadows.Came very well packaged and fast delivery, helpful delivery driver, I ordered another one.I'm impressed with quality and service.

They provide faulty item do not buy any panel its not giving actual power very low power eventhough in full sun
