Hyperion 400W bifacial panels - opinions?

D. Abineri said:

Does anyone have an opinion on the panels based on how closely they match the announced specifications. How well do they actually work?

I have 42 of these panels. 3 arrays ground mounted. I am happy with them thus far. Cannot tell you exactly if they are performing to spec as I have no way to test them definitively. I am over-paneled so I cannot get to maximum panel pv generation as I cannot use all the pv generated by the panels. I can tell you take it starts generating power a few minutes before actual sunrise and I peak and start clipping around 11am. I can process around 15kw before I start clipping as I feedback 12kW into grid and charge battery. If I had more battery then I could use more but that’s my situation.

Which Hyperion panel? Link?

Generally panel efficiency should be >22%, bifaciality >75%% and Pmax temp coefficiency -0,30%/C or under. If specs are worse than these you know they aren't latest technology commonly available. But if you get them cheap enough, they'll work just fine.

Usually panels meet their specs just fine, but it's the weather which is worse than ideal (too humid, too hot, low sun angle...).

I just also went back and checked when I had only 1 array with 12 panels up and peaked at just over 5300w pv generated and that was in January. Feb had 2 arrays up and peaked at close to 11kw. So I should be able to get 16kw with 3 arrays, I just clip way before then. Also they are angled for the spring and fall sun so should in theory max in mar and sep but no way I can reach max without additional batteries. I also peaked at 106kwh for a sunny day so far with the clipping. Not saying they are good/bad etc and really only time will tell if they hold up but that’s what I am currently experiencing with my setup.

Efficiency for 400W panel is 20,5%, bifaciality 70+-10% (=60-80%), temp coef -0,35%/C. Not excellent, not that bad either. Maybe two-three years ago these were top of the line panels, but not anymore. 0.32$/W is not cheap here for these kind of panels, but they might be were you are located.

Two months ago got quote from Bluesun 600W bifacials (N-type TOPCon, 23,2%, 80+-5% bifaciality, Pmax temp coef -0,30%/C (not Voc because Pmax tells you how much efficiency it loses when temp rises, Voc coef is needed for calculating string voltage in cold temps so it is important too). 0,19c/W all included (home delivery from China, VAT 24%). One pallet minimum.

These panels are successor for my current Bluesun 700W N-type chingled cell HJT, 22,8%, 70+-5% bifaciality, Pmax -0,35%/C. Year and half ago I paid 0,36c/W (or was it 0,34c/W can't remember for sure) for them.
