Specs: ShadowFlux 120W vs 100W Kit
Rated Power Output
Renogy ShadowFlux 120W N-Type Solar Panel delivers 120 watts of rated power. Renogy 100W 12V Solar Starter Kit provides 100 watts. The 120W panel generates more energy per hour of direct sunlight. This extra 20 watts helps charge batteries faster on clear days. You get higher total daily output with the ShadowFlux model. The 100W kit is sufficient for smaller battery banks. Choose the 120W unit if you need maximum power density. The 100W kit is a complete solution with a controller included.
Cell Efficiency
Renogy ShadowFlux 120W N-Type Solar Panel uses N-Type cells with 25% conversion efficiency. Renogy 100W 12V Solar Starter Kit uses Monocrystalline cells with 22.5% conversion efficiency. The 25% efficiency means the ShadowFlux panel converts more sunlight into electricity. This allows for higher power output in a smaller physical footprint. The 100W panel is efficient but lags behind the newer technology. Higher efficiency is critical when roof space is limited. You benefit from better performance per square foot with the ShadowFlux.
Included Components
Renogy 100W 12V Solar Starter Kit includes a 30A PWM Charge Controller, adaptor kit, tray cables, and mounting Z brackets. Renogy ShadowFlux 120W N-Type Solar Panel is sold as a panel only. The 100W kit is ready to install immediately with all necessary parts. You do not need to buy a separate controller for the starter kit. The ShadowFlux panel requires you to source a compatible charge controller separately. If you lack a controller, the 100W kit saves you time and extra purchases.
Physical Dimensions
Renogy ShadowFlux 120W N-Type Solar Panel measures 41.4 inches in length and 22.8 inches in width. Renogy 100W 12V Solar Starter Kit measures 41.8 inches in length and 20.9 inches in width. The ShadowFlux panel is slightly shorter but wider. The 100W panel is longer but narrower. Both units have similar overall footprints. The ShadowFlux is 10% more compact than standard PERC panels. Consider your mounting surface shape when choosing. The width difference may affect fit on certain RV roofs or small balconies.
Weight
Renogy ShadowFlux 120W N-Type Solar Panel weighs 19.1 pounds. Renogy 100W 12V Solar Starter Kit weighs 14.1 pounds. The 100W kit is lighter overall. However, the ShadowFlux panel includes no controller weight. The 100W kit weight includes the controller and cables. The panel alone in the 100W kit is likely lighter than the 120W panel. Heavier panels require sturdier mounting hardware. The 100W kit is easier to handle for single-person installation. Weight matters if you move panels frequently.
Choose based on your power needs
Users needing higher daily energy output
The ShadowFlux 120W panel delivers 120 watts of rated power, which is 20 watts more than the 100W kit.
