Any views on these sunstore solar panels?

[daventess]

I'm researching solar to death here, but I could get 3 of these on my roof :

Solmax Semi-Flexible Solar Panel 12v 150w - 1280x600 - Sunstore Solar

An impressively sturdy and heavy duty marine grade 12v 150w panel. Weighing approximately 3.1kg with a 0.9m cable.

www.sunstore.co.uk

giving me 540w which would out perform my batteries by a margin.

Any red flags? Are sunstore any good? Anyone had anything fitted by their linked installers https://www.motorhomeworkshop.co.uk/ ?

These look quite good, too :

200w Solar Panel black frame monocrystalline — Craig Solar

Monocrystalline cells, 9 busbar and 23% high efficiency. Solar cable with solar mc4 connectors. Bypass diodes in junction box to protect from shading. Quality aluminium frame with pre drilled holes on reverse and 3.2mm Tempered safety glass for optimal mechanical stability and transparency.

and they'd fit.

How would they be fitted to your roof if they were semi flexible.? If totally glued down without an air gap underneath they will soon deteriorate and lose performance. I dont see how they would be attached otherwise if not glued down.
They also seem to be expensive compared to rigid panels which will last 10 tomes longer.
Just my observations.
Ecoworthy do a 195watt bi facial panel which is rigid but allows light to transmit thru the panel and reflect from your roof to the underside approx £119 each
Think they are 670 x 1350mm

Thanks for that. I didn't even think of the consequences of flexible panels.

I'll check out the ecoworthy ones ...

Flexsble panels are best avoided they often fail in one to two years.

Noted - I'm kind of getting that feedback from a few places now.

I fitted 3 semi-flex panels three years ago and they are still working OK.

Exception proves the rule my flex panel is still working after nearly 5 years. Though it was fitted by sticking a big ridge of sikafkex at top and bottom so there is a half inch gap underneath the panel.

Yes they're the ones .The £219 is for 2 panels though.
Ps didnt see Lennys post conforming the same.
Pps
If you join the ecoworthy mailing list they give you a £10 discount code . But it's only valid for a few days so best to join just before you purchase anything.

They sound great but in practice I don't think you will gain anything as the back of the panel on a Motorhome roof will be completely shaded by the panel itself.
What is good is that they are ½ cells so will perform much better in shady conditions.
