Renogy Panel Specs Compared
wattage output
The Renogy ShadowFlux 120W N-Type Solar Panel delivers 120 watts of rated power. This is higher than the Renogy 100W 12V Solar Starter Kit with 30A PWM, which provides 100 watts. The ShadowFlux model generates more energy per hour of direct sunlight. You get 20 extra watts from the ShadowFlux unit. This difference matters if you need to charge larger battery banks faster. The 100W kit is sufficient for smaller 12V systems. The 120W panel offers a clear advantage in raw power generation capacity for your solar setup.
cell efficiency
Efficiency determines how much sunlight converts to electricity. The ShadowFlux panel uses N-Type cells with 25% conversion efficiency. The 100W starter kit uses panels with 22.5% efficiency. The ShadowFlux model is more efficient by 2.5 percentage points. Higher efficiency means you get more power from the same surface area. The ShadowFlux panel also features 16BB technology to reduce hot spots. The 100W kit mentions a 1.3% efficiency lead over other counterparts but does not specify the cell type. The ShadowFlux technology provides a technical edge in energy conversion.
included components
The Renogy 100W 12V Solar Starter Kit includes a Wanderer 30A PWM Charge Controller. This is a complete system ready to connect to a battery. The ShadowFlux 120W N-Type Solar Panel is sold as a panel only. It does not include a charge controller or mounting hardware in the base listing. You must purchase a controller separately for the ShadowFlux panel. The 100W kit offers immediate usability for beginners. The ShadowFlux panel requires additional components to function. This makes the starter kit more convenient for a turnkey solution.
physical size
The ShadowFlux panel measures 41.4 inches in length and 22.8 inches in width. It is 1.2 inches thick and weighs 19.1 pounds. The 100W kit panel measures 43.6 inches in length and 22.7 inches in width. It is 2.95 inches thick. The ShadowFlux panel is shorter and significantly thinner. It is also 10% more compact than PERC panels. The 100W panel is longer and bulkier. If you have limited roof space, the ShadowFlux panel fits better. The compact design allows for easier installation on smaller surfaces.
weather resistance
Both panels are built for outdoor use. The ShadowFlux panel has an IP67 rating for its enclosure and connectors. It withstands snow, rain, and hail. The 100W kit has an IP65 rated junction box and IP67 rated connectors. It withstands 2400Pa wind and 5400Pa snow loads. The ShadowFlux panel has a higher or equal IP rating for the main enclosure. The 100W kit lists specific wind and snow load metrics. Both offer strong durability. The ShadowFlux edge comes from its higher IP67 rating for the junction box area.
Choose your Renogy solar panel based on needs
You need maximum efficiency and shading tolerance
The ShadowFlux 120W N-Type panel offers 25% conversion efficiency, higher than the 100W kit’s 22.5%. Its N-Type cells with 16BB technology reduce hot spots and handle partial shading better. The 120W output provides more daily energy. It is also more compact and lighter, making it ideal for space-constrained roofs or vans where every watt counts.
You want a complete plug-and-play starter system
This kit includes a 30A PWM charge controller, which the ShadowFlux panel lacks. It supports expansion up to 400W with additional panels. The included Wanderer controller allows remote monitoring via an optional Bluetooth module. It is compatible with AGM, Gel, Flooded, and Lithium batteries, offering a ready-to-install solution for beginners without needing separate components.
You prioritize long-term service coverage
The 100W Starter Kit provides a 10-year warranty on materials and workmanship, compared to the ShadowFlux’s 5-year coverage. It also includes a 2-year plan for the charge controller. Both offer a 25-year power output warranty. If you prefer extended protection on the physical panel and included electronics, this kit delivers superior service terms.
