ARTsolar vs Sunpro - 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
Sunpro (Zhejiang Sunpro Power Technology Co., Ltd.), founded in 2006 and headquartered in China, is a BNEF-confirmed Tier 1 bankable manufacturer listed on the NYSE, with a production capacity stated at 85-100 GW and a workforce of roughly 33,800 employees. ARTsolar, founded in 2010 and based in South Africa, is the country's only locally owned PV manufacturer - operating at sub-GW scale (roughly 250-300 MW annually per publicly available reports) and not currently holding BNEF Tier 1 status. The institutional footprint is decisively broader for Sunpro: its scale, exchange listing, and bankability rating make it a straightforward choice for project finance structures, whereas ARTsolar's value proposition rests primarily on local content, in-country support, and domestic economic development goals.
From a portfolio standpoint, Sunpro fields 86 products averaging 546.7 Wp and peaking at 725 Wp, with a mean efficiency of 22.8% and a top efficiency of 24.62%. Roughly 70% of its lineup uses TOPCon cell technology and the entire catalogue is bifacial - a strong fit for utility-scale ground mounts and large commercial rooftops where rear-side gain materially improves yield. Its temperature coefficient averages -0.28%/degC per Pmax, better than the -0.31%/degC of ARTsolar. ARTsolar currently offers a single listed product at 600 Wp with a 23.21% efficiency - technically competitive at module level and using TOPCon throughout - but the portfolio has no bifacial option and no product variety, which limits it to monofacial residential and small commercial applications. Both manufacturers offer a 30-year performance warranty.
For a buyer outside South Africa in 2025, Sunpro is the more practical default: its Tier 1 bankability lowers financing costs, its broad high-power catalogue covers most project types, and its scale ensures supply continuity. ARTsolar is genuinely competitive on efficiency and TOPCon credentials at the module level, but its narrow product range and non-Tier-1 standing make it a specialist choice rather than a general-purpose recommendation - most suitable for South African buyers prioritising local procurement, PPPFA compliance, or projects where local content rules apply.
