POWEROAK SP200S Portable Solar Panel 220W Foldable Photovoltaic Solar Module with Monocrystalline Solar Cells to Charge Portable Power Station Solar Generator for Campervan Travel

Are used to have an Eco-worthy 120 solar panel and the most I’ve ever seen was about 35w Midsummer.I brought the bluetti 220 solar panel. And I’m very happy with it. I was getting 145w in October sunshine. Even when it’s cloudy it will still draw 40w. I should imagine when it’s summer it will probably achieve even more. It made easy work of powering up my Eb70. Looking at some of the reviews obviously I hope it’s going to last the longer term! That bit I can’t comment on.But I can honestly say I’m very impressed with the performance of this solar panel. It’s made the ones I had before seem more like a novelty. I’m even considering buying another one as spare because it’s so good and I’m probably going to become reliant on it. It’s a bit heavy but it is quite big and it’s certainly earns its space. If you want some serious watts then this one seems to do exactly that. I’ve got mine in a deal which made me feel a bit better than paying full price.

I have just purchased two of these SP120w panels. They only produce 124w when linked together, you can see in the picture that the sun is directly overhead and off by about 8-10 degrees of angle yet they can only work at 64w individually and 124w paired. Brand new out of the box from a cool room to mid day Middle East sun on an unobscured 37 degree temp day.Why label them 120W if in perfect conditions they can only produce half this?

The idea of these panels are great but in reality they are not robust enough and fail very quickly.If you have money to waste and will only use these panels a few times a year then they may last you a while, but if like me you want something to use on holiday and then lay out in your back garden to maximise to value of solar then forget it.I have had my panels replaced twice and now i will be selling secondhand and buying something better.These panels work fine for first 3 months or so but they soon deteriorate if left in the sun for extended periods. The material bleaches under UV and starts to break down and the panels themselves seem to gradually stain. In some cases they just stopped and in other cases they popped. I only ever laid them on a patio.I would guess that due to their portability they cannot keep out weather elements of any kind, sun, showers or condensation. Terrible return on investment, these things need to be lasting 10 years not 10 months.If you own an RV and want some occasional portable power you may get away with these, otherwise i recommend you find a way to utilise fixed solar panels as the are built for roofs and in general last much much longer.

I wanted solar panels to be more eco-friendly. These have broken after 2 years, I don't think putting something like this in a landfill and buying something else every 2 years is sustainable or what I was looking for. I'd recommend buying a more permanent, sturdy option from the get-go.

Brought a Bluetti ac50 power station and solar panel in June 2021. Solar panel will not charge now even in full sun . Wish I had gone with Jackery
