AE Solar vs MY Solar - solar panel manufacturer comparison

AE Solar is a German-headquartered photovoltaic manufacturer founded in 2003, with production facilities in China, Georgia, and Turkey, and a combined annual output capacity exceeding 2 GW. The company is recognized by Bloomberg NEF as Europe's sole Tier 1 PV module manufacturer with high bankability - a distinction confirmed in 2024 - and has established a commercial presence in over 95 countries. MY Solar, by contrast, does not hold Tier 1 bankable status, and publicly available information about its founding history, headquarters location, production capacity, or geographic reach is very limited. Its portfolio of 140 panels is considerably smaller than AE Solar's 442-panel lineup, which positions the two manufacturers in distinctly different market tiers.

AE Solar's product portfolio is led by TOPCon cell technology (approximately 50% of its lineup), achieving a maximum module efficiency of 24.43% and a portfolio average of 21.34%, with 63.8% of panels being bifacial and an average warranty period of nearly 30 years. The company received the Kiwa PVEL Top Performer Award 2025, reinforcing its performance and durability credentials. These characteristics make AE Solar a strong fit for utility-scale ground-mount projects, agrivoltaic installations, and commercial C&I applications where bifacial energy yield, bankability, and long-term guarantees are critical. MY Solar's portfolio is dominated by PERC technology (57.86%), with a lower average efficiency of 19.87%, a less favorable temperature coefficient of -0.333%/°C versus AE Solar's -0.313%/°C, a lower bifacial share of 38.57%, and an average warranty of approximately 27 years. MY Solar panels may appeal to cost-sensitive buyers in standard residential rooftop installations where Tier 1 status is not a lender requirement.

For international buyers - project developers, EPCs, or procurement teams - comparing the two, AE Solar presents a substantially stronger value proposition for any project requiring institutional financing, insurance-backed warranties, or grid-scale deployment. Its Tier 1 status, higher average efficiency, superior thermal performance, and larger bifacial portfolio share collectively reduce long-term project risk. MY Solar may serve as a budget alternative in small-scale residential deployments where upfront cost is the primary driver, but the absence of Tier 1 bankability and reliance on an aging PERC technology base limit its competitiveness in projects where lender due diligence or long-term asset value are key considerations.
