## Summary

Neo Solar Power (NSP) is a Taiwanese manufacturer founded in 2005 and headquartered in Hsinchu, Taiwan. The company rose to become the largest solar cell producer by revenue in Taiwan and ranked among the global top ten solar cell manufacturers by capacity as of 2013. However, in 2018 NSP completed a three-way merger with Gintech Energy and Solartech Energy to form United Renewable Energy Co., Ltd. (URE), and the Neo Solar Power brand effectively ceased to exist as an independent entity. Panels carrying the NSP name that still appear on distributor platforms represent legacy inventory rather than active current production. ARTsolar, by contrast, is an actively operating South African manufacturer founded in 2010 and based in Durban, KwaZulu-Natal. It is widely described as South Africa's only locally owned PV module manufacturer. In 2025, ARTsolar deepened a strategic partnership with JA Solar - a globally recognized Tier 1 supplier - to upgrade its Durban facility to a 340 MW assembly line producing JA Solar's DeepBlue 4.0 Pro n-type modules, including for the 216 MW Hydra utility project. ARTsolar holds a stronger and more current institutional footprint simply because it remains an operational business.

On the product side, NSP historically offered standard crystalline silicon modules in the 300-335 W range suited to residential and small commercial rooftop installations, but no new product families have been launched under that brand since the 2018 merger. ARTsolar's current lineup spans from roughly 500 W to 600 W and is built around TOPCon n-type cell technology, with its 550 W module rated at approximately 23% efficiency, a 12-year product warranty, and a 30-year power warranty retaining 87.4% of rated output. The portfolio targets commercial rooftop, C&I, and utility-scale ground-mount projects primarily across southern Africa.

For any buyer evaluating these two brands in 2025 or beyond, the comparison is asymmetric rather than competitive: Neo Solar Power no longer ships new panels under its own name, so procurement from that brand means buying legacy stock with uncertain supply continuity and no active manufacturer support. ARTsolar, with its JA Solar technology transfer and active 340 MW facility, is the only genuinely live option of the two, and it is a credible choice for buyers in the southern African market seeking locally assembled n-type modules backed by an internationally recognized technology partner.
