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
AEET Energy Group GmbH is a Germany-based photovoltaic wholesale distributor headquartered in Bad Gandersheim. Founded as a specialist PV reseller, AEET does not manufacture solar panels itself but instead sources modules from third-party producers and distributes them through a network of over 500 certified specialist partners across Germany. As a trading company rather than a module producer, AEET does not hold a BloombergNEF Tier 1 designation - that ranking applies only to manufacturers demonstrating bankable financials and a documented production track record. Renesola, by contrast, was founded in 2005 in China and listed on the New York Stock Exchange in 2008, building a substantial manufacturing base before pivoting its strategy. The company rebranded as Emeren Group Ltd in January 2023 and now operates primarily as a solar project developer and operator active in more than ten countries, while continuing to market PV modules under the Renesola name. Renesola has maintained a position on BloombergNEF's Tier 1 list for eleven or more consecutive quarters, giving it considerably stronger institutional recognition.
On the product side, AEET's catalog reflects its role as a multi-brand distributor: the panels it offers depend on which upstream manufacturers it partners with at a given time, so the cell technology mix can shift by season and procurement contract. Renesola's module lineup is more consistently documented; independent comparative testing places average panel efficiency in the low-to-mid 20 percent range with top models reaching around 23.5 percent, and Renesola products have demonstrated competitive results in third-party thermal cycling and power-degradation assessments.
For a commercial or utility buyer where project financing and lender due diligence are involved, Renesola's long-standing Tier 1 bankability status and traceable manufacturing history make it the clearer default choice. AEET may suit buyers within the German market seeking a single wholesale procurement point for mixed-brand orders, but it is not a like-for-like substitute for a vertically integrated module manufacturer and the two brands are best evaluated as serving different roles in the supply chain.
