Havells NDCR 590 Topcon Solar Panels

The Havells NDCR 590Topcon Panel is a premium photovoltaic module that sits at the cutting edge of solar technology.

Technology and Performance

This panel utilizes N-Type TOPCon (Tunnel Oxide Passivated Contact) cell technology, which is a significant step up from the older PERC modules. This N-Type technology ensures lower Light-Induced Degradation (LID) and lower annual power degradation (typically <span class="math-inline" data-math="$<0.40%$ per year after the first year), guaranteeing a much longer effective service life and better long-term power output, often backed by a 30-year performance warranty.

The panel’s maximum power output is 590 watts-peak (Wp) with a high module conversion efficiency of up to 22.84% or more.

Design and Energy Capture

The panel is engineered with a Bifacial Dual-Glass (Glass-to-Glass) design. This means the panel can generate electricity not just from the front side, but also from reflected and scattered light hitting the rear side. This allows for an additional energy gain of 10% to 30% depending on the ground surface (albedo), maximizing the energy yield from the installed area.

It is typically built using Half-Cut Cells (e.g., 144 cells) and Multi-Busbar (MBB) technology, which minimizes power loss within the cell structure and increases shadow tolerance.

NDCR Compliance and Durability

The NDCR designation means the panel is classified as Non-Domestic Content Requirement compliant. This is crucial for projects where there is no government mandate to use domestically manufactured solar cells or modules, providing flexibility in sourcing and use.

For durability, the panel features a robust construction with an Anodized Aluminum Frame and 2.0 mm low-iron AR-coated semi-tempered Dual Glass on both the front and back. This structure provides excellent protection against harsh weather, including high resistance to Potential Induced Degradation (PID), high humidity, salt mist, and ammonia, and can withstand a significant snow load of up to 5400 Pa.

This combination of advanced technology, dual-sided power generation, and high durability makes the Havells 590W TOPCon panel an ideal choice for large commercial, industrial, and utility-scale solar projects where maximizing energy yield and ensuring long-term reliability are key priorities.
