Replacing 100w Solar Panel

Post removed - because I called Chinese knock-offs knock-offs? PC cr-ap seems to have gone a bit far, in this instance.

Let's try again:
Kyocera is a good and well known brand. As I wrote in the earlier (removed) post, cheaper Chinese knock-offs are plentiful and it "looks" like they've now learned how to make them acceptable quality. So - doesn't matter much.

Any panel output will deteriorate by ~1% a year, and scratches on the glass will add to this. It will still "crank out the amps" but less and less, as years go by.

Bigger panels - over 150W - are typically cheaper per watt. $2/W is reasonable for small panels, but again, you can find small panels for $1.00-1.50 per Watt if you shop around. Check Solarblvd.com.

Amazon might have some with free S/H, though $22 from Az WindSun is very reasonable.

Stay away from Monocrystalline panels.

Amazon has some good prices.

The Kyocera panels are excellent. I originally chose them because of reputation and the footprint size for my old truck camper roof. Just purchased another last year and installed 2 of them on my Nash trailer. You can view my install in my signature

Try Renogy.com they have some good prices seem to be a lot cheaper price than a lot of places.

Good panel. Arizona wind and sun is one of the most expensive places to do business with. You can do better. Shop around.

I am not an expert in solar by any means, but have been reading up planning to install a system on mine in the next year or two. I have been looking at different panels and the one you listed seems to be on the expensive side at over $2/watt. Seems like you can get a similar size panel in the $1.30 to $1.40/watt ballpark.

Now if you are getting superior performance for that additional price, I have no clue...

I bought a 125w Kyocera 10 years ago from the same company and it's still cranking out the amps. BTW, paid $565 for it. I'm sure they are quite a bit cheaper now.
