ARTsolar vs NeMo - solar panel manufacturer comparison
Both brands are closely matched on catalog size, efficiency and bifacial share - the choice comes down to local availability, price and specific model features.
Both catalogues are read from the manufacturers' own datasheets. A brand is not scored against the market here, only against the other brand on this page.

Catalogue against catalogue
An average over a catalogue describes the range a manufacturer publishes, not the module you would buy. A brand with two flagship panels and eighty older ones averages worse than one that has retired its back catalogue.
What each of them builds
Written summary
NeMo is the flagship module product line of Heckert Solar GmbH, a German photovoltaic manufacturer headquartered across facilities in Chemnitz and Langenwetzendorf, Thuringia. The company is one of the few remaining solar module producers that manufactures exclusively in Europe and operates at a production scale of roughly 400 MWp per year - a relatively modest figure compared to Asian Tier 1 giants, but notable as a genuinely European industrial footprint. No BloombergNEF Tier 1 listing was confirmed in available sources, which reflects the company's regional rather than global scale. ARTsolar, trading as African Renewable Technologies, was founded in 2011 and is based in Pinetown, KwaZulu-Natal, South Africa, where it has marketed itself as South Africa's only locally owned solar panel manufacturer. The company received IDC (Industrial Development Corporation) funding in 2022 to expand its production line. However, its local-manufacturer status is currently under serious legal challenge - a North Gauteng High Court case filed in late 2024 includes affidavit evidence alleging that approximately 99% of ARTsolar's panels are imported from China, a claim the company contests. On institutional footing, Heckert Solar carries the more verifiable manufacturing pedigree.
NeMo modules are monocrystalline panels designed primarily for European residential rooftops and smaller commercial installations, with recent generations rated in the 375-405 W range. The product line is associated with robustness certifications suited to central European weather conditions, including high snow-load tolerance. ARTsolar's catalog covers residential and light-commercial segments across sub-Saharan Africa, and the company claims its portfolio includes TOPCon cell technology along with a 30-year performance warranty, though independent verification of those claims is limited in the sources reviewed.
For a typical buyer in 2025, these two brands serve almost entirely separate regional markets and would rarely be cross-shopped. A European buyer seeking a locally made, verifiable-provenance module would find NeMo a credible niche option. A South African buyer considering ARTsolar should factor in the unresolved court proceedings around local-content claims and the reported workforce reductions in mid-2025 before committing to a long-term installation dependent on that manufacturer's warranty support.
