- Safe to use NMOT ? vs sct - DIY Solar Power Forum
Thanks to all I now know what to look for (temp coefficients) to further calculate as well A harder question to answer is the NMOT business (as these panels are tested SCT in a super controlled environment, including the light source and wind ) Assume I stick with SCT and get a feel for the NMOT thing
- Selecting panels for very hot climate: how useful is NMOT?
The STC rating is 400W (the NMOT rating is 300W) At midday in the summer, we receive more than 1000 W sq meter, which exceeds STC test conditions Yet these "400 Watt" panels have never produced more than 280 W Reading the spec sheet and calculating power at MPP and derating for 50 degrees C tells me that the power should max out the
- Matching MPPT with NMOT data of solar panel
The MPPT charge controller can output 40A to a 12V battery system So it's rated for approximately 500W of solar I plan on using two panels in the system so obviously this would be exceeded if the SFC rating (600W) is used, but these are very specific laboratory conditions, though it would not if the NMOT rating (446W) is used
- NMOT - Why Not - DIY Solar Power Forum
but the usual lower NMOT numbers SignatureJames says the EG4 is good for up to 1 2 x 25a=30a Sol-Ark says the -15 self limits above 26a Older comments suggest STC provides a safety reserve but does the Canadian Solar really need 24% safety greater STC than NMOT for safety Watt reduction is 32% , maybe that string can be a few panels longer
- Doubt about reading nmot - DIY Solar Power Forum
The second nmot table, expresses values 49 30v and 11 50 A, very different values I don't understand if these values refer to another model even if they belong to the same document or I don't understand this difference Thank you
- Panel - Mppt startup voltage advise help! | DIY Solar Power Forum
- Luxen LNET-670M like you see on Luxen specs , panel is 670W , but under NMOT which is supposedly better rated gives 510W, 41 92v Voc, and 38 22V So my big question is , what's better for PV18-3024VHM ,going with Amerisolar NOCT 403W , 45 7 Voc , and 37 7V Vmp, or going with Luxen NMOT 510W, 41 92v Voc, and 38 22V , from what I can see the

STC standard temperature is 25°C He assumed your min temp was -20°C That is how his math got 45 Your mileage may vary and his VOC was an assumption but depending on your configuration you will have to multiply the number of panels in series time your specific panel VOC to get the total VOC for whatever configuration you choose
- Minimum MPPT working voltage with panel - DIY Solar Power Forum
So my big question is , what's better for PV18-3024VHM ,going with Amerisolar NOCT 403W , 45 7 Voc , and 37 7V Vmp, or going with Luxen NMOT 510W, 41 92v Voc, and 38 22V, from what I can see the mppt startup is 30volts minimum I was thinking going with luxen,but I will hear your advice like always
- Hot Weather Voltage Degradation | DIY Solar Power Forum
NOCT NMOT is approximately 80% irradiance (thus the 20% reduction in current), and cell module temperature is assumed to be in the 40-50°C range (varies by panel), so the 40 6Voc is likely what you'll see, not 36V, and yes, you definitely use STC for string Voc calcs because STC TEMPERATURE conditions can be seen in the real-world (sunrise where ambient temp is at a daily minimum)
- STC vs NOCT - DIY Solar Power Forum
STC for establishing limits, i e , max voltage or max current the equipment may experience NOCT for a more realistic expectation of performance
