The PV module under test shall be connected to the resistive load or maximum power point

tracking device.?被試光伏組件應(yīng)接最大功率點(diǎn)跟蹤裝置或負(fù)載電阻。

Throughout the test the following parameters shall be monitored:在整個(gè)實(shí)驗(yàn)過(guò)程中，應(yīng)監(jiān)測(cè)如下參數(shù)：

?? temperatures of PV module components and materials, as listed below;

? ?光伏組件部件和材料溫度，如下面所列

?? environmental temperature;

? ?環(huán)境溫度

?? irradiance;

? ?輻射強(qiáng)度

?? wind speed.

? ?風(fēng)速

The environmental temperature during the test may be in the range of 20 °C to 45 °C. The

irradiance during the test shall be between 700 W/m 2 and 1 000 W/m 2.

試驗(yàn)過(guò)程中，環(huán)境溫度范圍20 °C to 45 °C，輻照強(qiáng)度范圍700 W/m 2 -1 000 W/m 2.

–?28 – ?IEC 61730-2:2016 ? IEC 2016

If the irradiance is other than 1 000 W/m², take at least two measurements at other irradiance

levels (at least 80 W/m^2?apart) and then make a quadratic extrapolation to determine the

corrected module temperature at 1 000 W/m² irradiance.

如果輻照度不是1 000 W/m²，至少在其他兩個(gè)輻照度下測(cè)量（至少相隔80 W /m²），然后做一個(gè)二次外推法，以確定校正在1000 W /米²輻照度組件溫度。

It is permissible to reposition (track) the test platform to maintain a consistent irradiance level

throughout the test.

整個(gè)測(cè)試過(guò)程中，為了維持一致的輻照水平，可以重新定位（跟蹤）測(cè)試平臺(tái)。

All data shall be taken at wind-speeds of less than 1 m/s.

所有數(shù)據(jù)的采集應(yīng)在風(fēng)速小于1 m/s.的條件下

Stabilised temperature data for each test location shall be collected. Thermal stability has

been attained when three successive averaged values, taken 5 min apart, indicate a change

in temperatures of less than ± 2 K. Averaged values in this context are calculated from the

readings taken over a 1 min interval.

The measured component temperatures (T OBS ) shall be normalised by the addition of the

difference between the 40 °C reference environmental temperature and the measured

environmental temperature (T ENV ) according to the formula:

通過(guò)增加標(biāo)準(zhǔn)環(huán)境溫度（40°C）與實(shí)測(cè)環(huán)境溫度（t env）差值使測(cè)量元件的溫度（T OBS）恢復(fù)到標(biāo)稱溫度，根據(jù)公式：T_CON=T_?OBS?+?（40 °C- T_?ENV )

where T CON is the normalised temperature. T_CON是標(biāo)稱溫度。

If an unacceptable performance is encountered during the temperature test and the

performance is attributed to a test condition that although within the limits specified may be

considered more severe than necessary – for example an ambient temperature near the limits

allowed – the test may be conducted under conditions closer to the norm.
