Their solar modules are small-wattage units (10W–100W) made from monocrystalline silicon, primarily intended for autonomous and off-grid energy systems... ## Catalog & Power | Measure | MWG | ARTsolar | Margin | | --- | --- | --- | --- | | Panel Models | 2 | 0 | +2 | | Max Power | 400 W | 0 W | +400 W | | Avg Power | 370 W | 0 W | +370 W | ## Efficiency | Measure | MWG | ARTsolar | Margin | | --- | --- | --- | --- | | Max Efficiency | 20.12% | - | | | Avg Efficiency | 19.72% | - | | ## Reliability & Warranty | Measure | MWG | ARTsolar | Margin | | --- | --- | --- | --- | | Avg Temp Coefficient | -0.390%/°C | - | | | Bifacial Share | 0 (0%) | 0 (0%) | | | Avg Warranty | 25.0 yrs | - | | ## Efficiency distribution | Efficiency band | MWG | ARTsolar | | --- | --- | --- | | \<20% | 1 (50.0%) | 0 | | 20-21% | 1 (50.0%) | 0 | ## Power distribution | Power band | MWG | ARTsolar | | --- | --- | --- | | \<400W | 1 (50.0%) | 0 | | 400-499W | 1 (50.0%) | 0 | ## Cell technology | Technology | MWG | ARTsolar | | --- | --- | --- | | Unknown | 2 (100.0%) | 0 | ## Top panels, MWG | # | Model | Power | Efficiency | Temp. coefficient | Technology | | --- | --- | --- | --- | --- | --- | | 1 | [MWG-400M](https://comparepv.com/panel/mwg-mwg-400m) | 400 | 19.3 | -0.390 | Monocrystalline | | 2 | [MWG-340M](https://comparepv.com/panel/mwg-mwg-340m) | 340 | 20.1 | -0.390 | Monocrystalline | ## Summary MWG is a solar panel brand for which no credible industry profile currently exists in public databases, review platforms, or trade publications. Searches across EnergySage, SolarReviews, ComparePV, PV Magazine, and PV Tech return no usable results for MWG as a module manufacturer: the brand does not appear on any BloombergNEF Tier 1 list, no production capacity figures are on record, and no independent project references have been published. It is therefore not possible to characterize MWG's headquarters, founding history, annual output, or bankability without fabricating details. ARTsolar, by contrast, is a Durban, South Africa-based company founded in 2010 that markets itself as the only locally owned solar panel manufacturer on the continent. It is not listed among Tier 1 or BloombergNEF-bankable manufacturers, and its institutional footprint has been weakened by a high-profile 2025 court dispute in which it was alleged - via shipping records - that approximately 99 percent of its modules were imported from China rather than assembled locally. ARTsolar's current catalog includes both PERC and TOPCon N-type modules, with power ratings documented up to 600 W. The TOPCon line is positioned toward residential and light commercial rooftop installations across southern Africa, where the lower temperature coefficient of N-type cells offers a meaningful yield advantage in hot climates. Product datasheets list a 30-year performance warranty. Despite the controversy over local-content claims, the panels themselves have circulated widely enough in the South African market to attract third-party datasheet listings and distributor reviews. For a typical buyer in 2025, ARTsolar is the only brand of the two for which any verifiable product or company information exists, making a balanced head-to-head verdict impossible. If operating in the South African market, ARTsolar panels are commercially available and technically documented, but prospective buyers should weigh the unresolved legal and local-content controversy carefully. MWG cannot be recommended or dismissed on evidence, as no credible source confirms what it manufactures, where, or at what scale. \---LINKS--- \- https://groundup.org.za/article/local-manufacturer-actually-imports-99-its-product-court-told/ \| ARTsolar imports 99% of its product, court told - GroundUp \| article \- https://oxpeckers.org/2025/11/solar-court-case/ \| Court case tackles not-so-proudly-South African solar power - Oxpeckers \| article \- https://comparepv.com/reviews/artsolar \| ARTsolar Solar Panels Review - ComparePV \| review \- https://www.enfsolar.com/pv/panel-datasheet/crystalline/67050 \| ARTsolar 550W TOPCon N-Type panel datasheet - ENF Solar \| article \- https://www.pvknowhow.com/news/south-africa-solar-lawsuit-critical-2025-localisation-fight/ \| South Africa solar lawsuit - critical 2025 localisation fight - PVknowhow \| article Sources: \- \[ARTsolar imports 99% of its product, court told - GroundUp\](https://groundup.org.za/article/local-manufacturer-actually-imports-99-its-product-court-told/) \- \[Court case tackles not-so-proudly-South African solar power - Oxpeckers\](https://oxpeckers.org/2025/11/solar-court-case/) \- \[ARTsolar Solar Panels Review - ComparePV\](https://comparepv.com/reviews/artsolar) \- \[ARTsolar 550W TOPCon N-Type panel datasheet - ENF Solar\](https://www.enfsolar.com/pv/panel-datasheet/crystalline/67050) \- \[South Africa solar lawsuit - critical 2025 localisation fight - PVknowhow\](https://www.pvknowhow.com/news/south-africa-solar-lawsuit-critical-2025-localisation-fight/) Written by claude-sonnet from the figures above. ## Other comparisons - [MWG vs A.B.
