The Rich Solar MEGA 100 SLIM is a compact 100W 12V solar panel built for vans, overlanders, boats, RVs, trailers, fifth wheels, cabins, and space-limited off-grid power layouts. It is available as the MEGA 100 SLIM ONYX Black model under SKU RS-M100SLB and the MEGA 100 SLIM Silver model under SKU RS-M100SL25. This narrow solar panel uses tempered glass, aluminum, and monocrystalline silicon in a 50.0" × 15.7" × 1.2" frame that weighs 12.4 lb. Its N-Type TOPCon cell design, 100W output, listed IP67 protection for the junction box and solar cables, and 1000VDC maximum system voltage make it a practical option for properly planned mobile and off-grid systems. Compared with the MEGA 100 SLIM SLX, the MEGA 100 SLIM keeps the same 100W output in a listed 11.8% smaller footprint.
The MEGA 100 SLIM is designed for mounting areas where a standard-width 100-watt panel may be difficult to place. Its slim rectangular footprint helps maximize usable roof space on vans, Class B RVs, Class A RVs, trailers, fifth wheels, and boats.
This Rich Solar panel uses N-Type TOPCon solar technology, which Rich Solar describes as providing higher energy conversion than standard panels. Rich Solar also describes the panel as delivering reliable power in low light or extreme temperatures, with resistance to light-induced degradation; real-world output still depends on sunlight, mounting angle, wiring, and system design.
The MEGA 100 SLIM includes an IP67-rated junction box and solar cables for dust and water protection. It is listed to withstand 5400 Pa snow load and 2400 Pa wind load, with an operating temperature range of -40°F to +185°F.
Pre-drilled holes help simplify mounting on roofs or frames, while pre-attached MC4 connectors with 4 ft cables support straightforward setup planning. Final installation should still be based on compatible mounting hardware, wiring, charge control, battery storage, and system sizing.

The MEGA 100 SLIM gives mobile solar builders a narrow-panel format for roofs, racks, frames, and compact mounting layouts. Its 100W output and slim profile make it useful for vans, RVs, boats, overlanding rigs, cabins, and small off-grid systems.
With a 50.0" × 15.7" footprint, 12.4 lb weight, pre-drilled holes, and pre-attached MC4 connectors, this panel is built for practical installation planning. Pair it with compatible solar components and verify system requirements before installation.
