The Sun Earth SKT545~580M10-144D4 series is a premium module range designed for projects where maximizing energy yield per square meter is paramount. This series utilizes TOPCon monocrystalline cells in a half-cut configuration, which translates to improved performance at high temperatures, reduced internal losses, and more stable energy generation in varying weather conditions. The double-glass construction enhances resistance to microcracks and aging, while also facilitating long-term high efficiency.

This series is also bifacial, meaning it can utilize reflected light from the ground, making it particularly well-suited for roofs with light-colored membranes, ground-mounted installations, and industrial settings where the environment can be designed for optimal energy gain. A key advantage over many competing modules is the long power warranty, which simplifies investment planning and financing.

Common questions

6 answered
Is the Sun Earth SKT545~580M10-144D4 series still available for purchase?
The SKT545~580M10-144D4 series has been discontinued by the manufacturer. New direct shipments from Sun Earth are no longer available. Limited stock may still exist with some distributors, but anyone planning a larger installation should verify availability before placing an order or consider sourcing a current equivalent with comparable specifications.
What product and power output warranties come with the Sun Earth SKT545~580M10-144D4 modules?
Sun Earth covers the SKT545~580M10-144D4 with a 15-year product warranty against manufacturing and material defects, plus a 30-year linear power output warranty. A 30-year power guarantee is a premium-tier benchmark that simplifies long-term yield modeling and supports project financing requirements for commercial and industrial installations.
What does bifacial mean on the SKT545~580M10-144D4 and is the extra cost justified?
Bifacial means the module generates power from both sides — the rear glass captures albedo light reflected off the ground or roof surface. The gain is most significant on bright membranes, white gravel, or snow-covered surfaces, and can add several to over ten percent in annual yield. For ground-mount and industrial systems where the surrounding environment can be designed intentionally, bifacial is a proven strategy for reducing LCOE.
Are the Sun Earth SKT545~580M10-144D4 modules suitable for large ground-mount and industrial projects?
Yes, the 144-cell format rated up to 580 Wp is aimed primarily at commercial and utility-scale applications. The double glass construction improves mechanical strength and long-term weather resistance, while bifacial operation allows site designers to optimize ground reflectivity for additional yield. The high per-module wattage also reduces total module count and balance-of-system (BoS) costs per megawatt.
How does TOPCon cell technology in the SKT545~580M10-144D4 compare to standard PERC modules?
TOPCon (Tunnel Oxide Passivated Contact) is the generation of cell technology that follows PERC. A thin tunnel oxide layer reduces carrier recombination, resulting in higher conversion efficiency and a better temperature coefficient — the module loses proportionally less power on hot days. In real-world conditions, this translates into higher annual energy yield per square meter compared to conventional PERC panels.
How do Sun Earth SKT545~580M10-144D4 panels handle partial shading?
The half-cut cell layout splits each cell in half, which lowers resistive losses and limits the impact of partial shading on overall module output. When a shadow falls on only part of the panel, the unshaded half continues to operate effectively. This is a meaningful advantage in installations where obstructions — chimneys, antennas, or adjacent rows in large rooftop arrays — cannot be fully avoided.
