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.

Written summary
ASM, trading as Australian Solar Manufacturing, is a Victoria-based assembler founded in 2009. It does not manufacture photovoltaic cells; instead it sources components from Germany, Japan, the United States, and China and assembles them domestically - a positioning that has historically appealed to buyers with a strict Australian-made preference. ASM does not appear on any BloombergNEF Tier 1 bankability list, and its public institutional footprint is very limited. Vespa Solar Enerji, registered as Vespa Enerji San. Tic. A.S., is a Turkish manufacturer established in 2022. It is a newer entrant with an active listing in the ENF Solar directory and produces crystalline modules under the VSP-T brand name, though no Tier 1 or BNEF bankability classification was confirmed in available sources either. Neither company operates at the multi-gigawatt scale of mainstream global suppliers, but Vespa Solar Enerji's more recent founding reflects the rapid build-out of Turkey's module manufacturing base.
On the product side, the contrast is stark. ASM's catalogued modules top out in the 170 Wp to 200 Wp range, specifications that are well below the 400-500 Wp+ threshold now standard on any modern rooftop or commercial project. That wattage band is relevant only for legacy or very small off-grid setups. Vespa Solar Enerji's VSP-T series spans 445 Wp to 555 Wp and uses PERC and bifacial cell technology, making it compatible with current residential, commercial, and light utility-scale installations.
For a typical 2025 buyer evaluating these two specifically, Vespa Solar Enerji is the more practical choice simply because its panel specifications align with modern system design requirements. That said, neither brand carries the independent performance history, warranty track record, or bankability documentation that most project financiers or experienced installers expect, so buyers with flexibility should compare both against established Tier 1 suppliers before committing.
