Kensol vs AEET - solar panel manufacturer comparison

AEET Energy Group GmbH is a Germany-based photovoltaic wholesale partner headquartered in Bad Gandersheim; it functions primarily as a reseller and system integrator rather than a vertically integrated manufacturer, with no publicly confirmed production capacity in GW or founding year on record. Kensol, by contrast, is a Polish solar panel manufacturer founded in 2014 and headquartered in Gliwice, Poland, with an active product line targeting European residential and commercial markets. Neither company appears on Bloomberg NEF's Tier 1 bankable list as of 2025, which places both outside the financing tier required for most large utility-scale projects and limits their practical market to self-funded or lender-flexible installations. On institutional footprint, Kensol has the edge by virtue of a more transparent corporate identity and a significantly larger cataloged product portfolio.

The technology gap between the two lineups is substantial. AEET's five-panel catalog averages 190 Wp and 14.9% efficiency, with a peak of 200 Wp at 15.7% - figures consistent with older standard monocrystalline or polycrystalline modules rather than current mainstream products. None of its panels are bifacial, and cell technology is unspecified, limiting transparency for technical buyers. Kensol's 21-panel range averages 437 Wp and 22.0% efficiency, climbing to 460 Wp and 23.0% at the top end, with approximately 81% of models available in bifacial configuration. Its average temperature coefficient of -0.30%/°C is competitive for modern monocrystalline PERC-class products, and an average warranty of roughly 29 years outpaces AEET's 25-year term. AEET's lower-power modules suit buyers repowering older installations with existing racking constraints; Kensol fits modern residential rooftops and mid-scale commercial projects where roof area is limited and per-panel output is a priority.

For a new installation in 2025, Kensol is the stronger default across virtually every technical metric - higher wattage, higher efficiency, bifacial versatility, and a longer average warranty. The key shared limitation is the absence of Tier 1 status: neither brand qualifies for project finance structures that require bankable modules, so buyers in that segment will need to look beyond both. Within their natural self-funded market, Kensol's portfolio is clearly the more current and capable offering.
