## Summary

ARTsolar is a South African solar panel manufacturer founded in 2010 in Durban by Eshu Seevnarayan and Patrick Goss, making it one of the only fully domestically owned PV module producers on the African continent. The company originally built a production line designed for up to 300 MW per year, though it operated below that level for several years. It is not independently ranked as a Tier 1 manufacturer, but its bankability has been bolstered by successive partnerships - first with LONGi Solar and more recently with JA Solar, under which it now assembles approximately 340 MW of high-efficiency modules annually at its upgraded Durban facility. RedSolar, formally Hunan RedSolar New Energy Technology Co., Ltd., was established in 2008 in Changsha, China, as a state-owned enterprise incubated by the 48th Research Institute of the China Electronics Technology Group Corporation (CETC), drawing on six decades of semiconductor and photovoltaic research. The company claims to have delivered over 30 GW of PV products across more than 50 countries. On raw institutional footprint and international track record, RedSolar holds the stronger position.

ARTsolar's catalog covers residential rooftop, commercial, and light industrial applications primarily within the South African and sub-Saharan African market. Its panels are monocrystalline and the company has referenced TOPCon cell technology in recent product lines. RedSolar markets a broader range - from smaller residential modules up to large-format series designed for commercial and utility-scale ground-mount installations - and its CETC parentage gives it credibility in technically demanding or government-backed project work. RedSolar has also built out system integration capabilities, supporting full project delivery beyond module supply alone.

For a buyer in South Africa seeking locally assembled panels with domestic content credentials under government procurement programs such as REIPPPP, ARTsolar is the practical default. For a buyer outside South Africa, or running a utility-scale project where international bankability and supply chain depth matter more than local sourcing, RedSolar offers greater scale and a longer global track record. The two brands serve distinctly different geographies and project scales and are not meaningfully interchangeable.
