HardKorr 170 watt Solar Panels

HK is a brand where you will find mixed reports.Mine is one of the negatives. You may find a post here by me around the middle of last year where I reported that my HK 200W folding mat's output declined rapidly from new, and was eventually replaced under warranty.

Well the replacement went the same way and I got a refund. One of the four panels had lost 75% of its output and another lost 15% compared to the best performing two panels. There is a more detailed report on Caravanners Forum. I'm still looking for a replacement, but have become a bit wary of the longevity of these semi-soft folding panels / mats.

I can't fault HK on their handling of the warranty claims. However I have seen other reports of multiple failures, including one on my CF thread. HK have a good reputation, but I get the impression that something has slipped.

I have that panel John. I bought it for its weight saving and low profile. Only had it for twelve months and haven’t performed any tests other than it works and keeps my lithium battery charged

These people have a pretty good reputation, might be worth a look.https://www.solar4rvs.com.au/

Hi John
I have 2 of these, one for the camper and one for the tug. Both have 200AH batts in them and the solar panels keep both of them charged up. The camper has a 75l fridge, lights, fans, etc and the tug has a 65lt fridge, lights, chargers, etc. Haven't had any problems with them. Cheers.

I’m looking around for a couple of 150W (approx) semi flexible panels…for their lightweight .
Not for mounting , but to stand on the ground.
One thing to keep in mind is their rated output. Lots of makers are making rubbish claims about outputs.
I’d like to buy one in person so I can do a short circuit test on it before buying.

I've had 2 HK panels replaced under warranty and now my 3rd one is a poor performer. Not going to bother returning them under warranty - waste of my time.
