Technology and R&D

The module is available in five versions with power output ranging from 310 W to 330 W and efficiencies between 20.22 and 21.53%. The Chinese manufacturer claims the BIPV panel has an oustanding flexibility with minimum curve radius of 25 cm.

State utility SA Water is partnering with an environmental organization to ‘re-vegetate’ almost a ton of native seedlings under a large scale solar arrays. Beneath the ground-mounted PV projects, native vegetation should return to the formerly agricultural land, and the resulting scrub is expected to protect panels from soiling.

Finnish company ICS has developed a foil which it claims can significantly increase the yield of solar panels, when applied to the edges of a PV module. Germany’s Fraunhofer ISE has confirmed that the increase in performance for conventional solar modules with the solar film is ranging from 5% to 10%.

The Chinese manufacturer has claimed a world record for a large-size, contact-passivated solar cell. The result, certified by Germany’s Institute for Solar Energy Research in Hamelin, betters the company’s previous record by almost 0.6%.

Two new pass/fail protocols are said to be able to separate cells which present high hot-spot possibility, show high current leakage and demonstrate intermediate behavior. The sorting technique relies on a manual solar simulator, an infrared camera and a tool to measure isolation.

Scientists in the U.S. have estimated the expense of strengthening solar systems. The researchers stressed that the upfront investment needed to take 13 key measures may be outweighed by the benefits.

Scientists in the United Kingdom have investigated the formation of cracks in PV cells, confirming that the high temperatures cells are exposed to during soldering for interconnection are a leading cause of cracking. Their findings will aid future research into module reliability and predictions of how cracks are likely to form.

The system can metallize the front and back sides of silicon solar cells with unprecedented precision and speed, Fraunhofer ISE said. The technology is also suitable for components such as printed circuit boards or chip cards.

Results from PID stress tests can be misleading when bifacial PV modules are PID-stressed from just one side using the foil method in IEC TS 62804, according to a new study by Belgian researchers. An unintended electric field arises between the non-stressed side of the cell and the grounded interior of the climate chamber, which may have the undesired effect of causing additional PID stress.

The containerized product integrates a grid connection with multiple charging systems, enabling electric public transport and commercial fleet operators to charge more vehicles with less infrastructure needed at depots.
