Rich Solar MEGA 100 2026 100 Watt 12V Solar Panel

The Rich Solar MEGA 100 2026 100 Watt 12V Solar Panel Puts N-Type TOPCon Cells to Work Charging 12V Batteries in Vans, Campers, Boats and Cabins

The Rich Solar MEGA 100 2026 100 Watt 12V Solar Panel (model RS-M100-26) is a rigid panel for 12V off-grid power systems. It uses 30 N-Type TOPCon multi-busbar cells with up to 25.3% cell efficiency and a 20.0% module efficiency, behind 3.2 mm AR-coated tempered glass in an anodized aluminum frame. The panel measures 44.1 x 17.6 x 1.2 inches and weighs 13.2 pounds.

You can order one panel (RS-M100-26) or two panels (RS-M100-26-2) for 200W of total rated power. Rich Solar designs the MEGA 100 2026 for RVs, camper vans, off-grid cabins and marine systems, certifies it to UL 61730, IEC 61215 and CSA C22.2 No. 61730, and backs it with a 25-year output warranty and a 10-year workmanship warranty.

Rich Solar MEGA 100 2026 100 Watt 12V Solar Panel Features

N-Type TOPCon Cells With 20.0% Module Efficiency

The 30-cell layout produces 100W at 17.6V and 5.68A. N-Type TOPCon multi-busbar cells reach up to 25.3% cell efficiency, giving the panel a 20.0% module efficiency. Power tolerance is positive only, so each panel is rated to deliver at least 100W at standard test conditions.

Holds Output in Heat and Low Light

A low power temperature coefficient of -0.35%/°C helps the panel maintain output in hot weather. Rich Solar also designs it to keep producing on cloudy days and at dawn and dusk.

Built for Long-Term Reliability

Non-destructive cell cutting helps minimize micro-cracks, and the PID-resistant design supports long-term performance. The panel is built to withstand salt, ammonia, sand, high temperatures and humidity, and it is rated for 5400 Pa positive and 2400 Pa negative loads. The operating range is -40°F to +185°F.

Twelve Mounting Holes and Pre-Attached Leads

Twelve pre-drilled holes in the anodized aluminum frame fit Z brackets, tilt mounts, pole mounts and ground installations. Pre-attached 12AWG leads, 35.4 inches each, end in MC4 connectors, and the junction box and connectors are both rated IP67.

UL Certified

The MEGA 100 2026 is certified to UL 61730, IEC 61215 and CSA C22.2 No. 61730, which helps when an installation calls for listed equipment.

Real-World Applications

Camper vans. The 17.6 inch width suits narrow roof space, and two panels give 200W of rated power for a 12V house battery.

RVs and trailers. Add 100W or 200W of charging to keep a 12V house battery topped up.

Boats. Rich Solar lists marine systems among the panel's uses, and the IP67-rated junction box and connectors suit outdoor installations.

Off-grid cabins. Build a small 12V solar array that can grow with series or parallel wiring.

Practical Comparison

One Panel Versus the 2 Panels Option

One panel gives 100W of rated power from a 44.1 x 17.6 inch footprint. The 2 Panels option doubles that to 200W, and the panels can be wired in series or parallel to suit your charge controller.

MEGA 100 2026 Versus a Flexible Panel

A flexible panel is made to follow curved surfaces. The MEGA 100 2026 is a rigid panel with 3.2 mm tempered glass and an anodized aluminum frame, rated for 5400 Pa and 2400 Pa loads, and it mounts through twelve pre-drilled holes.

Buyer Guidance

Check Your Controller and Wiring

Each panel has a 22.8V open circuit voltage and a 5.98A short circuit current. Two panels in series double the voltage, and two in parallel double the current, so check both figures against your charge controller's input limits. Open circuit voltage rises in cold weather, with a temperature coefficient of -0.28%/°C, so leave headroom. The maximum system voltage is 1000VDC and the maximum series fuse rating is 10A.

Plan the Mounting

Mounting hardware isn't included. Choose Z brackets for a roof, or a tilt, pole or ground mount, and line them up with the pre-drilled holes. Allow 44.1 x 17.6 inches per panel.

This May Be A Good Fit If

• You run a 12V battery system in a van, RV, boat or cabin
• You want N-Type TOPCon cells with 20.0% module efficiency
• You need UL 61730 certified panels
• You want one panel now or a matched pair

Common Questions

What Is the Difference Between the Two Options?

The 1 Panel option (RS-M100-26) includes one MEGA 100 2026. The 2 Panels option (RS-M100-26-2) includes two identical panels for 200W of total rated power.

How Big Is the MEGA 100 2026?

Each panel measures 44.1 x 17.6 x 1.2 inches (1120 x 448 x 30 mm) and weighs 13.2 pounds (6 kg).

Does It Work With Inverters and Optimizers?

Rich Solar lists the panel as compatible with mainstream solar inverters, optimizers and mounting systems, and it supports series and parallel configurations.

What Warranty Does It Carry?

Rich Solar provides a 25-year output warranty and a 10-year workmanship warranty.

What's Included

• 1 x Rich Solar MEGA 100 2026 Solar Panel With Pre-Attached MC4 Cables (1 Panel option) or 2 x (2 Panels option)
