Rich Solar MEGA 100 Two-Pack — 2 × 100W Solar Panels
This RS-M100-2 package contains two Rich Solar MEGA 100 monocrystalline solar panels. Each panel is rated at 100W and 12V nominal, for 200W of combined panel nameplate power. Per-panel dimensions are 39.0 × 21.3 × 1.2 inches and per-panel weight is 13.2 lb. The panels' voltage and current depend on series or parallel wiring, so size the charge controller and electrical protection from the individual module ratings below.
2 × RS-M100 MEGA 100 panels · 100W rated per panel · 200W combined nameplate power. Use each panel's voltage and current ratings below when planning the array.
Grade A+ Cells, 22.6% Module Efficiency
Premium-binned Grade A+ monocrystalline cells in a 33-cell module deliver 22.6% module efficiency — strong output per square inch for a 100W panel, with consistent performance across the full range of outdoor light conditions including diffuse and low-angle light.
IP67 Weatherproof, TPT Backsheet
IP67-rated junction box and MC4 connectors seal out rain, dust, and moisture. A weatherproof TPT backsheet and AR-coated tempered glass front surface protect the cell layer from UV degradation, thermal cycling, and long-term outdoor exposure.
30+ QC Tests, 100% EL Inspected
Every MEGA 100 passes 30+ mechanical and electrical quality checks — including UV, thermal cycling, humidity-freeze testing, PID resistance validation, and 100% double EL imaging inspection to detect micro-cracks before shipment. Backed by a 25-year output warranty.
Product Overview
The Rich Solar MEGA 100 is a 100-watt monocrystalline solar panel designed for 12-volt off-grid systems across the full range of applications — from first-time solar builds and single-panel starter kits to supplemental charging additions on existing RV, van, boat, and cabin arrays. At 39.0 × 21.3 × 1.2 inches and 13.2 lbs, it's easy to handle, position, and mount solo on virtually any surface or mounting hardware configuration.
The 100W wattage class is the most popular entry point in off-grid solar — and the MEGA 100 is built to the same quality standard as the larger panels in the MEGA lineup, not a stripped-down budget version. Grade A+ monocrystalline cells in a 33-cell module deliver 22.6% module efficiency with a 0~±5W power tolerance, meaning every panel ships at or above its 100W nameplate rating. Built-in bypass diodes in the IP67-rated junction box maintain stable output under partial shading conditions common on rooftop installations near antennas, vents, and rails.
The panel's TPT (Tedlar-Polyester-Tedlar) backsheet is a meaningful durability feature at this price point — TPT resists UV degradation, moisture penetration, and electrical insulation breakdown more effectively than lower-cost PET backing materials, contributing to longer service life in permanent outdoor installations. AR-coated high-transmission tempered glass on the front surface reduces reflective losses and improves low-light energy capture throughout the day. With a 1000V maximum system voltage rating and plug-and-play MC4 connectors, the MEGA 100 connects cleanly into both simple single-panel setups and larger multi-panel arrays.
Performance You Can Count On
- Grade A+ Monocrystalline Cells: Premium-binned cells selected for consistent efficiency, output stability, and long operational service life — not the lower-grade cells used in budget 100W panels at similar price points.
- 22.6% Module Efficiency: Strong efficiency rating for a 33-cell 100W module — more usable power per square inch than standard or polycrystalline 100W designs.
- Low-Light Performance: AR-coated glass and high-sensitivity monocrystalline cells generate meaningful output on overcast days, in diffuse light, and during early morning and late evening hours.
- Shading-Resistant with Bypass Diodes: Built-in bypass diodes prevent shaded cells from pulling down output from unshaded sections — important on rooftops where partial shading from vents, antennas, and rails is common.
- 0~±5W Positive Power Tolerance: Output is tested at or above the 100W nameplate rating at standard test conditions before every panel leaves the factory.
Built for All-Weather Outdoor Durability
- IP67 Waterproof Junction Box & MC4 Connectors: Fully sealed against dust and water ingress — reliable through rain, condensation, salt air, and high-humidity marine and rooftop environments.
- TPT Backsheet: Tedlar-Polyester-Tedlar backing provides superior UV resistance, moisture barrier performance, and electrical insulation compared to lower-cost PET backing materials used in budget panels.
- AR-Coated Tempered Glass: Anti-reflective coating reduces surface reflection and increases light transmission; tempered construction resists impact from hail, debris, and mechanical stress.
- 2400 Pa Wind Load / 5400 Pa Snow Load: Certified for the same structural load ratings as every other panel in the MEGA lineup — engineered for permanent outdoor installation through all seasons.
- Wide Operating Temperature Range: Functions reliably from -40°F to +185°F, covering desert summer rooftops through mountain winters without performance compromise.
Rigorous Quality at Every Price Point
- 100% Double EL Inspection: Every single MEGA 100 panel is imaged using electroluminescence diagnostics before shipment — detecting micro-cracks and cell defects invisible to the naked eye that would degrade output over time.
- 30+ In-House Quality Tests: UV exposure, thermal cycling, humidity-freeze simulation, high potential testing, and PID resistance validation — the same test protocol used across the full MEGA lineup regardless of wattage.
- PID Resistant: Engineered to resist potential-induced degradation, protecting long-term output in string array configurations with higher system voltages.
- UL, FCC & CE Certified: Triple certification covers both electrical safety and electromagnetic compatibility — verified for use in U.S., Canadian, and international markets.
- 25-Year Linear Output Warranty: Guaranteed output retention of 95%+ at year 5, 90%+ at year 10, and 80%+ at year 25 — backed by Rich Solar's U.S.-based support team.
Easy Setup for First-Timers and Experienced Builders Alike
- 13.2 lbs — Easy Solo Handling: Light enough for one person to carry, position, and fasten on any rooftop or ground-mount surface without mechanical lifting assistance.
- Pre-Drilled Mounting Holes: Compatible with Z-brackets, tilt mounts, pole mounts, and ground-mount frames — no additional drilling required for most standard mounting hardware.
- Plug-and-Play MC4 Connectors: Pre-attached 35-inch IP67 MC4 leads for fast, tool-free connection to your charge controller or adjacent panels in a series or parallel configuration.
- Series or Parallel Ready: Wire multiple MEGA 100s in parallel to increase current for a 12V battery bank, or in series to raise voltage for an MPPT charge controller input — flexible for both simple and advanced array builds.
- Available in Silver or Onyx Black: Choose the frame finish that suits your vehicle, rooftop, or ground-mount installation aesthetic.
