ECO-WORTHY vs Topsolar Panel Specs
Cell Technology
ECO-WORTHY uses N-Type monocrystalline cells with 16BB busbar technology, achieving up to 25% conversion efficiency. This design reduces hot spots and micro-cracks for better reliability. Topsolar uses standard P-type monocrystalline cells. The data does not list a specific efficiency percentage for Topsolar. N-Type cells generally offer higher power output and superior low-light performance compared to traditional P-type cells. If you need maximum energy harvest per square inch, the advanced cell structure in the ECO-WORTHY panel provides a clear technical advantage.
Included Accessories
Topsolar sells a complete kit that includes four Z-mounting brackets and a pair of red and black solar cables. It also includes a 30A PWM charge controller to prevent overcharging and short circuits. ECO-WORTHY lists the panels only, with 35-inch cables and pre-drilled holes for installation. The ECO-WORTHY junction box is IP68 rated and waterproof. Topsolar does not mention the junction box rating in the provided data. If you want a ready-to-install system with mounting hardware and a controller, Topsolar offers more components out of the box.
Physical Dimensions
The ECO-WORTHY panel measures 35.2 inches in length, 23 inches in width, and 1.38 inches in height. It weighs 23.8 pounds. The Topsolar panel measures 47.2 inches in length, 19.7 inches in width, and 1.18 inches in height. It weighs 15.2 pounds. Topsolar is significantly lighter and narrower, which may suit tighter spaces. ECO-WORTHY is wider and heavier, potentially offering more stability against wind due to its broader surface area. The thickness of ECO-WORTHY is listed as 1.18 inches in features but 1.38 inches in specs; we use the spec sheet value.
Weather Resistance
Topsolar withstands high winds of 2400Pa and snow loads of 5400Pa. It uses strong tempered glass and an aluminum frame. ECO-WORTHY mentions a sturdy build that withstands harsh weather and rapid heat dissipation due to its 1.18-inch thickness. The ECO-WORTHY junction box is explicitly rated IP68 for waterproofing, which minimizes power drop in low-light or wet conditions. Topsolar does not list an IP rating for its junction box. For electrical protection against moisture, the IP68 rating on the ECO-WORTHY panel provides a specific, verifiable advantage.
System Compatibility
Both panels support 12V and 24V systems for off-grid, on-grid, or hybrid use. Topsolar specifies a maximum system expansion of 260W for 12V or 520W for 24V when using its included controller. ECO-WORTHY allows you to extend your existing system but does not list a maximum wattage limit in the provided data. Both use 18V nominal voltage, which is standard for charging 12V batteries. The Topsolar controller offers reversed polarity protection and battery protection features, which adds a layer of safety for beginners who might not have an external controller.
