Munich, Germany, 7th May, 2025 — At the opening day of Intersolar Europe 2025, AESOLAR proudly launched Déjà Vu, a next-generation retrofit module designed to replace aging solar panels from around 2010 without modifying existing system infrastructure—engineered for a new era of solar retrofitting.
Back in 2010, the world was just beginning to embrace solar on a larger scale. AESOLAR was there—designing and producing durable, high-performance modules that powered the early global solar movement. Fast forward to today, and many of those systems are approaching the end of their optimal operational lifespan. They’ve served reliably for 15 years or more, but the march of time and technological progress waits for no one.
Déjà Vu is our response to this moment.

Built using the latest N-Type TOPCon cell technology, Déjà Vu delivers upgraded efficiency, reduced temperature sensitivity, and longer-term reliability. But what makes it truly unique is its compatibility: Déjà Vu has been specifically designed to match the exact dimensions and electrical parameters of modules from the 2010 era, allowing for easy, one-to-one replacement, which dramatically reduces labor, material, and downtime costs for retrofit projects.
No rewiring. No racking redesigns. No system overhauls. Just remove and replace.
Why Now? The Industry is Ready
Déjà Vu allows solar asset owners, EPCs, and O&M providers to perform upgrades without disrupting the existing infrastructure. It significantly reduces labor, material, and downtime costs for retrofit projects. With its plug-and-play design, Déjà Vu is particularly well-suited for large-scale retrofitting projects across utility and commercial sectors, as well as in public installations where preserving the original system layout is essential. Applications of Déjà Vu Include:
- Utility and commercial retrofits of aging PV systems
- O&M providers managing repowering operations
- Asset owners looking to extend ROI with minimal system change
- Asset life extension initiatives
By enabling faster upgrade cycles, Déjà Vu minimizes logistical challenges and permits complexity. It empowers older systems to meet the latest performance standards without needing complete system redesigns.
Eras Shift, Commitment Stays
As a German-engineered PV manufacturer with over 20 years of industry experience, AESOLAR has been named to BloombergNEF’s Tier 1 list 16 times and continues to focus on long-term system reliability, innovation, and global deployment. We invite you to experience the Déjà Vu module firsthand at Stand A3.280 at Intersolar Europe 2025 in Munich. Our team will be on hand to demonstrate the benefits of this unique retrofit solution and share how Deja Vu can help you reduce retrofit costs, streamline operations, and maximize output—without rebuilding from scratch.
