Renogy 100W 12V Monocrystalline Solar Panel, model RNG-100D-SS, uses a rigid framed design with tempered glass and monocrystalline cells. The panel measures 41.8 x 20.9 x 1.4 inches and weighs 14.1 pounds.

Core Electrical Specifications

The module is rated at 100 watts under standard test conditions. Renogy lists an optimum operating voltage of 20.4 volts, an optimum operating current of 4.91 amps, an open-circuit voltage of 24.3 volts, and a short-circuit current of 5.21 amps.

The panel uses 36 monocrystalline cells arranged in a 3-by-12 layout. Its maximum system voltage is 600 volts DC under UL specifications, while the maximum series fuse rating is 15 amps.

Size And Off-Grid Fit

The 41.8-inch length and 20.9-inch width create a footprint suited to RV roofs, boats, cabins, and other 12-volt off-grid installations. At 14.1 pounds, the rigid panel is substantially heavier than Renogy's 5.3-pound flexible 100-watt model, which measures 43.0 x 22.9 x 0.1 inches.

The rigid construction uses an anodized aluminum frame and tempered front glass. Renogy's documentation lists an operating temperature range from -40°F to 176°F, an IP65 panel rating, and 14 AWG output cables measuring 1.97 feet.

Price And Practical Position

Home Depot lists the RNG-100D-SS at $94.95 as of 09/22/2026. Renogy's current 100-watt rigid-panel lineup also includes newer designs, including an N-type series, but the RNG-100D-SS remains a clearly identified 100-watt, 12-volt panel.

Compared with the flexible alternative, the rigid RNG-100D-SS trades lower weight for a thicker, glass-covered frame. The flexible panel weighs 5.3 pounds and carries a 0.1-inch thickness listing, while the rigid panel weighs 14.1 pounds and measures 1.4 inches thick.

Verdict For RV And Backup Systems

The Renogy RNG-100D-SS fits buyers who need a conventional 100-watt panel for a 12-volt RV, boat, cabin, or battery system and have room for a rigid frame. Its 100-watt output rating, 600-volt maximum system voltage, and 15-amp fuse rating define the electrical envelope; the 14.1-pound weight and 41.8-by-20.9-inch footprint define the installation demands.
