One, module air drying heating curve
Test event: heating curve under outdoor active energy module air drying (without working medium) in real time
Testing location: Qihe County, Dezhou City Shandong Province
Test condition: the average 600W/m of intensity of illumination2Outdoor temperature 5 DEG C
Testing time: 11:00 ~ 13:00 tests inclination angle: 45 °
Test instrunment: Jinzhou sunlight meteorology company limited TBQ-2 illumination irradiation with one, the SMD temperature sensor of KYW-T1 (internal adopt PT100 chip), data collecting system。Test philosophy figure is shown in Figure 10。
Module air drying intensification performance testing time end is 11:00 to 13:00 in the morning, because time period terrestrial solar radiation intensity is the highest, can substantially determine the accessible maximum temperature of module thermal-arrest and heating rate。Because the testing time is in winter, outdoor mean temperature is 5 DEG C, shows that in testing time section, sunlight average lamp intensity is 600W/m according to irradiatometer2, fluctuating error is not less than 50W/m2。Module testing inclination angle is 37 °, adopts SMD PT100 temperature sensor that module photoelectric heat generator heating layer is carried out temperature data acquisition, and acquisition interval is 1min。Module air drying heating curve such as Figure 11。By the flat plate collector that module known in figure is general compared with market, there is higher limit heat-collecting temperature, can reach 120 DEG C。But its thermal response is relatively slow, the more common heat collector speed that heats up is relatively slow, delayed about 50 minutes。
2, module light thermal property test curve
Test event: actively energy module photo-thermal newly can test curve (national standard method of testing)
Testing location: Daan City, Baicheng City in Jilin Province great An Changli New Energy Technology Co., Ltd.
Test condition: the average 800W/m of intensity of illumination2Outdoor temperature 25 DEG C
Testing time: 11:00 ~ 13:00 tests inclination angle: 45 °
Test instrunment: Jinzhou sunlight meteorology company limited TBQ-2 illumination irradiation with one, 2.5KW auxiliary electrical heater, attemperater, PT100 Tube Temperature Sensor, the SMD temperature sensor of KYW-T1 (internal adopt PT100 chip), data collecting system。Test philosophy figure is shown in Figure 12。
National standard according to heat collector test, in during the whole test of outdoor test, intensity of solar radiation should at 700W/m2Above, and the excursion allowed be ± 50W/m2。According to whole day solar radiation rule, selecting 11:00 to 13:00 is testing time section。Because actively energy module air drying maximum temperature can reach 120 DEG C, in the unit interval, intensification also can reach more than 60 DEG C, therefore selects heat collector fluid inlet temperature respectively 25 DEG C, 42 DEG C, 56 DEG C, 63 DEG C。
Test starts, it is first determined switch butterfly valve is closed。Opening auxiliary electric heater unit in water tank A, the water temperature in heating water tank A is to room temperature 25 DEG C。Auxiliary electric heater unit can detect water tank temperature sensor automatically thus automatically starting stopping。Later on water circulating pump, utilizing flow control valve to arrange test flow is 70L/h。After ON cycle pump 5min, treat that heat collector reaches stable to start afterwards to record each sensor values, test period be 4min once。
Then opened butterfly valve, makes the heated water in B water tank flow into A water tank, then continues on power compensation device, heat the water to 42 DEG C successively, 56 DEG C, 63 DEG C of measurements carried out under each working condition。
Then with method of least square, test data are carried outLinear fit, matched curve is Figure 13 such as。
From figure it can be seen that module light thermal property relatively existing market light hot product light thermal property slightly declines, but remain above the 40% smooth thermal efficiency of national standard。Its peak light thermal efficiency is about 68%。
And after being filled with noble gas between photoelectric heat generator three deck panels, its light thermal efficiency all has and promotes by a small margin。This is that surface heat loss reduces by 10% thus causing that module light thermal property improves owing to the thermal resistance value of Bai Bo with the relatively interior aeriferous double glazing of the thermal resistance value of the hollow layer of noble gas combination improves 10%。
3, module photoelectric properties test curve
Utilize the special I-V curve tester of photovoltaic cell, can the direct output precision photovoltaic efficiency change curve when actual operating conditions。Because module design operating conditions, Temperature of Working, not higher than 25 DEG C, therefore passes into 15 DEG C of tap water moment to its cooling, and flow is 200L/h。Test philosophy is as shown in figure 14。The photoelectric transformation efficiency curve tested is as shown in figure 15。
The Changing Pattern of module photovoltaic power is consistent with the Changing Pattern of intensity of solar radiation, is approximately parabolic type。Photovoltaic module output increases along with the increase of solar irradiance, and the meridian hour reaches maximum, reduces along with the intensity of illumination irradiance subsequently and reduces。The working environment that main cause is residing when being for analog module commencement of commercial operation, passes into tap water that temperature is 15 DEG C all the time and its cooling is greatly reduced raises thus impact on output along with irradiance raises the module temperature caused when test。Therefore its photoelectric transformation efficiency is basic consistent with terrestrial solar radiation intensity。
It is also noted that the photoelectric efficiency excursion that this module shows is between 13.4% ~ 17.2%, and common polycrystalline silicon assembly its photoelectric efficiency when actual motion is typically between 12% ~ 16% to fluctuate。Illustrate this polysilicon members still have when the surface super low iron glass of many two-layers the photoelectric transformation efficiency consistent with common component even at high irradiation working environment under its photoelectric efficiency also slightly above common component, photoelectric properties are superior。
