Together with the renewal of the accreditation of ELIOSYS for a new period of 5 years, the national Belgian accreditation body BELAC recently validated the scope extension of accredited tests of ELIOSYS by adding the PID susceptibility and the electroluminescence tests.

These new tests are enriching the test capabilities of ELIOSYS regarding the existing set supporting the IEC 61215, IEC 61646 and IEC 61730 standards, but also these 2 new tests are fully aligned with the initiative of the Walloon government to improve the quality level of the new PV installations in the Walloon region.
Finally, it should be underlined that a test report mentioning results of accredited tests may serve as a legal reference and is only questionable by another laboratory with an equal or higher level of accreditation for identical tests.
On the August 13th and 14th, the Eliosys Team was mobilized to execute multiple tests on the SolarCar. Eliosys is one of the sponsors of the SolarTeam of 2013 and was requested to proceed with PV performance evaluation, cartography of the cells and some thermography analysis. The SolarCar is supposed to participate to the World Solar Challenge in Australia next October 6 to 13. through a distance of 3000 km between Darwin and Adelaide across the desert. The vehicle is relying only on the sun energy to run the electric engine and to charge its onboard battery. Therefore, it is crucial that the PV installation is well characterized to be able to finish the race with a potential podium participation.
For the performance tests, Eliosys was using his large steady state sun simulator. The size of the simulator along with the irradiation capabilities could made the PV performance evaluation under similar conditions as they can be found in the Australian desert. The achieved results are helping the team to finalize their vehicle behavioral model before the start of the race.
For the cartography of the cells, the electroluminescence of the complete car (4,5m long by 1,8m wide) was realised using the high definition EL camera of Eliosys. The results are showing some minor defaults, but the engineers team from the SolarTeam did a great job during the integration of the modules on the vehicle.
The thermography analysis was finally confirming the absence of hotspots which is decreasing the risk figures related to overheating zones on the car and, by a matter of facts, reducing the sources of defaults.

On May 21st, in collaboration with the cluster TWEED, Eliosys invites you to meet his team during the presentations of its activities in the field of quality (ELIOQUAL Label) for the photovoltaic industry. After each session, in the lab you will be to assist to demonstrations on our test benches.
We look forward to welcome you at this first event …
The Eliosys team.
ELIOSYS is proud to present the first phase of its all in-house designed solar simulator!
Briefly, a few features:
- 8 constant solar sources of 4kW each
- radiation surface up to 3x4m
- mobile light source, 2 axes
- angle d’incidence from 0 à 90° motorized
Within 6 months, the second development phase will be finalized, completing the offer with:
- motorized sample holder – 3 axes
- automated annual solar simulation (1 year in 4h!)
Since the beginning of December, Eliosys has moved into its new premises. By tripling our working surface we intend to treat your requests in an even more professional way and to install our new coming pieces of equipment. You are of course welcome to visit our new laboratory.
Please note that our adress remains the same!
As from the 1st of October, ELIOSYS’ lab is equipped with an Electroluminescence camera and is therefore able to provide this extraordinary service to its customers.
Electroluminescence is used as a mean of nondestructive control test (NDC) for the inspection of PV modules. It is based on the following principle: once submitted to a current, a PV cell emits radiation in the range of near IR. Thanks to this specific camera, it is possible to harvest this radiation in order to obtain an image of the source. Thus, it is possible to detect fragments of or entire cells which do not take part in the current production once submitted to solar radiation. These so called “dead zones” appear black on the final picture.

As of May 10th 2011, ELIOSYS is officialy accredited ISO 17025 by BELAC as a Testing Laboratory for the following standards:
– IEC 61215 (Crystalline silicon terrestrial photovoltaic);
– IEC 61646 (Thin-film terrestrial photovoltaic);
– IEC 61730 (Photovoltaic module safety qualification).
Accreditation number: BELAC-432-TEST.
