LONGi Hi-MO 6 Explorer vs Bluesun Bifacial

Hi, new here. I live in NZ.

I have been researching solar for about a year now and have finely decided to get some. I was going to use a Deye 6kw with 18 Bluesun Topcon All Black 450W – BSM450M10-54HNH (ground mounted). But my supplier has told that the LONGi Hi-MO 6 Explorer LR5-54HTB Mono 425W are better for low light, high rain areas. He can supply both and the Bluesun are cheaper. I have watch most of "Projects With Everyday Dave" videos and I would of thought bifacial were better, but what are your thoughts.

I know this may be a bit of a hot topic as I have spent over 4 hours to night doing research and found nothing conclusive 🤣

You may have already run across the recent discussion on this here, but for the benefit of future readers, there are some anecdotes shared in this thread:


I purchased the LONGi Hi-Mo 6 Explorer LR5-72HTH- 580M (580 watts) panels. I'm in Thailand with good sun and an annual rainy season of about four to five months. I have been quite happy with their performance so far--just one rainy season weathered so far, as the panels have been installed for not quite a year.

I have had no opportunity for direct comparison to bifacials, but the Hi-mo 6 panels are becoming difficult to find on the market here now, almost entirely replaced by the Hi-mo 7 panels. It seems the bifacial panels will be considerably heavier because of having glass on both sides of the solar cells. Aside from this, and their initial cost, I'm not aware of any significant drawbacks to them.

I have "a bit" different climate here, but have been using Deye12Ks with 700W Bluesun bifacials for almost two years now. There's a link in my signature if you want to find out more.

In every case you should always pick bipanels over mono if ground mounted (if they are about the same price). In warmer climate temp coef (Pmax) should be -0,30%/C or even less if you can find any. Bifaciality factor should be around 0,8 or higher. Also N-type cells degrade much slower than P-type.

Low light production is always bad so there's not much to gain. Maybe percentage wise, but not actually.

Is there going to be any hard shadows over your array?
 
There will be some hard shadows early mornings and late afternoon, with a bit more in winter. The main reason for the question about the panel is that I would have thought the bifacials would have be better but the supplier is saying that the HBPC cells are better for poor light/rainy days. Is he just trying to sell me them? Jinko say the N-type are better and Longi say HBPC are better :rolleyes:

The Bluesun bifacials are actually cheaper. That why I was wondering if the Longi were better.

Have seen your stuff love it.

Jinko is one of the more common brands here, and the panels are a bit cheaper, depending where they are sourced. But my research indicated LONGi was among the top five or six panels, even in America. During my research I watched a sort of docuvertisment that explained LONGi's extensive research, and helped me feel like the company is actually producing some original ideas, not just copy/pasting from everyone else. Because a relative of the one I was installing the panels for recommended LONGi, I basically went that direction. That said, I have been quite pleased so far with their performance. But I don't have any experience with other brands by which to compare them.

Hard shadows are nasty with string inverters. But if you have them only sunrise/sunset it's not going to affect total production much.

Bipanels greatly benefit from light colored surroundings (white pebbles, white building wall, snow) so if this is possible for your array, I think you should go with them. Mentioned Bluesuns have better specs than my two year old ones, so they aren't bad in any way. Nothing bad to say about those Longi monopanels either. They have really good Tc(Pmax), but surprisingly low module efficiency compared to other specs which is weird. Both have topcon technology and low degradation.

Bipanels are usually heavier so that can sometimes make installation bit harder. I know that now...
