GSOLA Sun Simulator Performs Excellent

In “Proficiency Testing on the electrical performance of bi-facial PV modules”

SERIS (Solar Energy Research Institute of Singapore ) organized Proficiency Testing on Bi-Facial Solar Module IV properties, which started from Jan 2018, tier 1 labs from 13 countries and regions took participate in this inter-comparison, such as NREL, JRC, AIST, Fraunhofer and etc.

In Apr of 2020, SERIS issued the final report. The testing data from Gsola lab is same with international tier 1 labs, it proves that China made solar simulator meets the international standards and has same performance with solar simulator in tier 1 labs.

The test was performed strictly according to IEC60904-1-2. It required all participants test main IV parameters of mono-facial and bi-facial module samples at different conditions, including short –circuit current (Isc), open-circuit Voltage (Voc), front Power (Pmax,f), rear Power(Pmax,r), total max power (Pmax), Bifaciality and etc……

In the test, results from the world's top laboratories were used as reference and were compared with other participants. Evaluation of performance was based on the calculation of Z score and En score. The Score shall be Good, Satisfactory, Questionable or Unsatisfactory.

GSOLA values the inter-comparison. From beginning, GSOLA cooperated with NIM (National Institute of Metrology) closely, took Measurement Uncertainty into account, bought 2 kinds of high precision reference solar cells, and corrected spectrum mis-match……. Gsola flasher is scored as Good for all samples testing, including 2 pcs mono-facial modules and 3 pcs bi-facial modules.

“GSOLA always values products quality, they invite third authority to calculate all of new products to ensure good stability and high precision, they deserve to get such good result in this inter-comparison” said by Professor Xiong from NIM.

The test verifies the testing capability of authoritative laboratories across the world, which helps to improve testing stability and accuracy, promote technical exchanges and discussions among international laboratories, and guide PV industry to development with higher quality.

Because of Bi-facial solar module development, SERIS organized the Proficiency Testing. It started from Jan in 2018, famous research institutions and laboratories from 13 countries and regions took participate in, such as NREL , JRC, AIST, Fraunhofer and so on…….

Last Tuesday, United Nations Industrial Development Organization International Solar Energy Center For Technology Promotion & Transfer（UNIDO） organized over 40 officials from 21 countries, like Grenada, Cuba, Djibouti, Panama, Pakistan, Ethiopia, Cambodia, Ghana, Cameroon and other countries, to visit Gsolar Power Co.,Ltd - the leading solar industry equipment manufacturing enterprise.

Mr. Huang (GM), warmly welcomed national officials. They exchanged opinions about China PV market trends and potential cooperation with each other. Both sides communicated in strengthening the cooperation and promoting the solar industry worldwide.

Company leaders introduced our history, honors, achievements to our new friends and showed guests around our workshop. The officials showed great interests and satisfied in our new equipment.

Two new launched devices are XJCM-11 and GEL-M10.

XJCM-11 is a sophisticated sun simulator. The new generation solar simulator (model: XJCM-11) performed at A+A+A+ level in non-uniformity of irradiance, spectral match and temporal instability of irradiance. The testing features are twice better than international standard (IEC 60904-9).

- Wider spectrum: Spectrum range is extended from 400-1100nm to 300-1200nm, this improvement solves 300-400nm spectrum missing problem, which could make the testing result of high-efficiency solar cells and modules more accurate.

- Longer pulse duration: Pulse duration was extended from 10ms to 200ms, and it’s adjustable. Longer pulse duration make it possible to effect accurate testing to PERC, HIT, IBC and other modules with higher efficiency.

- GEL-M10 is our latest EL deficiency detector which applies one camera with 24million pixels by three shots. Its good testing result makes it a star product in china.

- More than 42 million effective pixels, Germany customized lens, guarantee the picture quality.

- Customized optical filters (no dark room needed).

- More than 11 kinds of picture software processing functions and 4K display screen. Provide you an ever clearest picture.

- The equipment has the certificate of Institute of Metrology, its measurement result ≤0.3 mm/lp, which is currently the best resolution.

After this visit, United Nations delegation highly praised the development of Gsolar and positively emphasized that there’s large room to cooperate with each other. We hope Gsolar will do better in solar equipment manufacturing and help with solar industry in the future.

Gsolar firstly launch ‘Three In One’ solar simulator around the world (A+A+A+/full spectrum/long pulse)

Gsolar Power Co., Ltd (hereafter referred to as Gsolar) will show the 11th generation of unthinkable product - A+A+A+/full spectrum/long pulse solar simulator(model :XJCM -11A ), during SNEC expo (2016) in shanghai.

It is reported that this top test equipment, integrated three of the world's leading indexes:

• 1. A+A+A+ performance. Non-uniformity of irradiance, Spectral match, Temporal instability of irradiance, these three core performance indexes are twice better than highest international standard (IEC 60904-9).
• 2. Full spectrum. Spectrum range is extended from 400-1100nm to 300-1200nm, so this solves 300-400nm spectrum lost problems existed among most of solar simulators on the market. Full spectrum accomplishes Improve testing accuracy effectively of high-efficiency solar cell.
• 3. Long pulse. Testing pulse width can be extended from 10ms to 150ms, even 200ms. This makes it meet requirements for testing PERC, HIT, IBC and other new technology solar cells and solve the test deviation caused by large capacitance effect.

Gsolar solar module tester won the award “PV industry outstanding innovative technical application in 2015”

On 15th January 2016, Gsolar’s innovative application, Full Spectrum solar simulator (shell reflecting model), won the award “PV industry outstanding innovative technical application in 2015”. This award is for commending the attribution to the PV industry and spreading the latest Technological achievements, chosen by “PV industry observation”. Gsolar is running ahead among related PV equipment manufacturing companies, highly rated by experts in this field.

Full Spectrum solar simulator (shell reflecting model) model faces down, using xenon to simulate the sun light for testing. Three core performance indexes fit the A+A+A+ standard, and are all twice better than the highest international standard (IEC 60904-92007). The improved structure of equipment makes spectrum range extend to 300-1200nm, which could also be 1700nm and even wider. The new XJCM-10A+ can test most kinds of silicon solar cells. High accuracy infrared thermometer and four-wire configuration connected solar module make test results more accuracy. It’s convenient to use, each testing time is less than 1 second and test interval could be less than 10 seconds. The prospect of it is promising and the equipment performance gains the recognition of a lot of experts.

The project leader said: the application of full spectrum solar simulator break the monopolization in this field and provide the necessary reference for PV equipment especially solar test equipment domestic production level. Besides, this will increase productivity and decrease the production costs markedly.

This new testing technique reduces testing costs sharply, it could also help cut the module generating costs. In addition, lots of solar module manufacturers have already put it into operation and this attracts more and more companies’ attention overseas. The testing results show the excellent stability, accuracy, more importantly, the maintenance cost is lower than before, so that would be a wise choice to use this XJCN-10A+ to replace the outdated or expensive equipment.

Gsolar high-end automatic assembly line running successfully in India

It is reported that Gsolar Power Co.,Ltd (hereinafter referred to as "Gsolar") exports 75MW high-class automatic module line to India.
