The company operates primarily as a PV component supplier, system integrator, and OEM/ODM solutions provider, rather than a large-scale module manufacturer. No Tier 1 or BloombergNEF bankability listing was found for Clelo Tech, and confirmed annual production figures in GW are not publicly available. ARTsolar, standing for African Renewable Technologies, was founded in 2010 in Pinetown, Durban, and is 100% locally owned - making it South Africa's only domestically owned solar panel manufacturer. ARTsolar holds TUV SUD and ISO certifications and has built manufacturing partnerships with global Tier 1 suppliers including LONGi Solar and, as of June 2025, JA Solar, for whom it assembles 340 MW of modules per year at its upgraded Durban facility. ARTsolar carries the stronger institutional footprint, backed by formal Tier 1 OEM relationships and a growing profile in South Africa's utility-scale procurement programs. Clelo Tech's product range spans residential to utility-scale configurations and reportedly includes monocrystalline, bifacial, TOPCon, IBC, and HJT panels, with some high-wattage HJT products listed in industry databases. The company appears best suited to buyers seeking customized or private-label modules sourced from a Chinese supply chain partner. ARTsolar's product portfolio centers on monocrystalline and TOPCon modules - including JA Solar's n-type DeepBlue 4.0 Pro line assembled locally - and is primarily targeted at South African commercial, industrial, and utility-scale projects. ARTsolar's position is reinforced by local content requirements under South Africa's independent power producer procurement programs, making it a natural fit for any project that needs domestically manufactured panels to qualify under those rules. For a buyer operating in South Africa or sub-Saharan Africa, ARTsolar is the more practical default in 2025, given its local manufacturing base, established OEM credentials, and direct alignment with national procurement incentives. Clelo Tech may be worth evaluating for buyers seeking OEM flexibility from a Chinese supplier, but its limited public track record makes due diligence more demanding. \---LINKS--- \- https://www.pv-magazine.com/2025/06/17/ja-solar-artsolar-agree-to-expand-pv-module-manufacturing-in-south-africa/ \| JA Solar and ARTsolar agree to expand PV module manufacturing in South Africa \| article \- https://www.pv-magazine.com/2026/05/13/artsolar-challenges-local-content-compliance-in-south-african-solar-tenders/ \| ARTsolar challenges local content compliance in South African solar tenders \| article \- https://www.enfsolar.com/clelo-tech \| Jiangsu Clelo Material Technologies - ENF Solar company profile \| article \- https://www.climatescorecard.org/2025/02/artsolar-in-south-africa/ \| ARTsolar in South Africa - Climate Scorecard profile \| article \- https://www.greenbuildingafrica.co.za/south-africa-longi-solar-to-partner-with-local-solar-pv-panel-manufacturer-artsolar/ \| LONGi Solar to partner with ARTsolar for 1 GW South Africa capacity \| article Sources: \- \[JA Solar, ARTsolar agree to expand PV module manufacturing in South Africa\](https://www.pv-magazine.com/2025/06/17/ja-solar-artsolar-agree-to-expand-pv-module-manufacturing-in-south-africa/) \- \[ARTsolar challenges local content compliance in South African solar tenders\](https://www.pv-magazine.com/2026/05/13/artsolar-challenges-local-content-compliance-in-south-african-solar-tenders/) \- \[Jiangsu Clelo Material Technologies - ENF Solar\](https://www.enfsolar.com/clelo-tech) \- \[ARTsolar in South Africa - Climate Scorecard\](https://www.climatescorecard.org/2025/02/artsolar-in-south-africa/) \- \[LONGi Solar to partner with ARTsolar - Green Building Africa\](https://www.greenbuildingafrica.co.za/south-africa-longi-solar-to-partner-with-local-solar-pv-panel-manufacturer-artsolar/) Written by claude-sonnet from the figures above. ## Other comparisons - [Clelo Tech vs A.B.
