AEET Energy Group GmbH is a Germany-based photovoltaic wholesale distributor and systems integrator headquartered in Bad Gandersheim, Lower Saxony. The company has been active in the PV sector for a number of years and positions itself as a full-service partner - advising on system design, supplying hardware, and managing installation and maintenance through a network of more than 500 TÜV Rheinland-certified specialist partners across Germany. Critically, AEET is not a panel manufacturer in the conventional sense; it procures modules from established producers and resells them under a wholesale model. No BloombergNEF Tier 1 listing was found for AEET in available sources. MY Solar Technology Co., Ltd. (branded as MY Solar or MYPVTECH) is a Chinese manufacturer founded in 2010 and based in Wuxi, Jiangsu. The company produces solar modules alongside inverters and energy storage systems, positioning itself as a vertically integrated supplier. No confirmed BloombergNEF Tier 1 designation or publicly verified annual shipment figure was found for MY Solar in the sources reviewed. Given its European wholesale network and TÜV certifications, AEET has the stronger institutional footprint within the German and broader European market.

Because AEET functions as a distributor rather than an original equipment manufacturer, its product offering reflects the catalogs of the third-party brands it stocks, which typically include modules suited to residential rooftops and small-to-medium commercial installations in Central Europe. MY Solar Technology, by contrast, develops its own module lines targeting both residential and commercial segments, and the brand's public-facing materials reference HJT and shingled cell formats, though independent verification of current production volumes and certified efficiency figures was not available in the sources consulted. MY Solar distributes globally through wholesale and OEM channels, which is typical of mid-tier Chinese producers seeking international market share.

For a buyer in 2025, the choice depends heavily on geography and purpose. Installers or developers operating within Germany may find AEET's service model and local logistics advantageous, though they should verify which underlying module brands AEET is currently stocking. Buyers seeking a direct-from-factory supply relationship with a Chinese producer should treat MY Solar as one option among many mid-sized Chinese OEMs, and should request third-party test reports and financial references before committing, given the absence of a confirmed Tier 1 bankability rating in publicly available records.
