The Chinese again contact module maker mentioned its new merchandise depend on the corporate’s all-back-contact (ABC) cell expertise and have a temperature coefficient of -0.26% per C.
At Intersolar Munich 2024, Chinese photo voltaic cell and module maker Aiko Solar showcased its Generation 3 Comet collection of photo voltaic panels that featured a world file energy conversion effectivity of 25.2%.
“The new merchandise depend on our proprietary all-back-contact (ABC) photo voltaic cell expertise,” Claudio Godinho, Europe Service Director of Aiko Solar, mentioned. pv journal on the firm’s sales space in Munich. “The Comet Generation 3 photo voltaic module might be out there within the fourth quarter of 2024. The module might be manufactured at their 10 GW and 14 GW services.”
Godinho famous that the modules use solely copper of their rear-facing photo voltaic cell connections. The firm says they’ll use copper, which might doubtless require thicker busbars, partly as a result of they’ve moved the connections to the again of the module.
Five variations of the brand new module collection can be found, with output energy from 625 W to 650 W and effectivity from 24.2% to 25.2%. The open-circuit voltage is between 54.49 V and 54.99 V and the short-circuit present is between 14.60 A and 15.00 A. It has dimensions of two,278 mm x 1,134 mm x 30 mm and weight which is 27 kg.
All merchandise are constructed with 3.2 mm tempered anti-reflective glass and aluminum frames. They additionally function an IP68 enclosure and a most system voltage of 1,500 V. The panels have a temperature coefficient of -0.26%/C and an operational temperature from -40 C to 85 C.
Aiko Solar gives a 30-year efficiency guarantee, with a claimed 1% degradation within the first 12 months and a assured finish energy output of at least 88.85% of nominal energy after 30 years.
The module has photo voltaic cells that overlap by about 0.3 mm. This reportedly generates extra electrical energy inside the identical space – including roughly 0.5% extra silicon that faces the solar. The switch of all string connectors – the ABC expertise – to the again of the module will increase the sunshine absorption space by 1.1%, in response to the producer.
Aiko says that roughly 93.5% of the photo voltaic module’s floor space is photo voltaic cells. Moving the photo voltaic cell interconnections to the again facet of the photo voltaic panel can decrease the bifaciality of the product to 70%. The rear contacts additionally give the module benefits in partial shade conditions.
