Replacing 100w Solar Panel

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.

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...

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

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

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

Amazon has some good prices.

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.

What would the reason be to stay away from Mono ?

If be curious to know that took. When I was reading the differences between poly and mono, it seemed like mono was better for RV type use. Don't exactly remember why though....

Poly is more efficient. There "used to be" that mono were much more efficient, but today in specs there may be mere 1-2% difference between the two. In real world poly would fare better as they drop less under cloudy skies.

If you are concerned about efficiency and can't add more panel wattage, you might want to replace the controller with MPPT as well.
