Rich Solar MEGA 370 PRO ONYX Watt Solar Panel Features

This panel turns more sunlight into power than most rivals

Nine busbars work together to shorten the electrical path inside each cell. The result is up to 22.8% efficiency meaning more of the sun's energy becomes usable electricity for your home, RV, or off-grid setup.

Cloudy days won't stop this panel from charging your batteries

The MEGA 370 PRO ONYX captures diffuse light on overcast mornings and low-sun evenings. Your batteries keep charging even when the sky turns grey a huge advantage for RVers, cabin owners, and anyone relying on solar daily.

Rain, salt air, and moisture cannot get inside this panel

The IP68-rated junction box and MC4 connectors are fully sealed against water. Whether you're on a boat, a beach, or battling a rainy season, every electrical connection stays protected and your power output stays strong.

Heavy snow and strong winds will not knock this panel down

Certified to handle 5,400 Pa of snow load and 2,400 Pa of wind pressure, this panel is built tough. Mountain winters and coastal storms are no match for its reinforced anodized aluminum frame and tempered glass.

Installing this panel is easy no matter where you mount it

Sixteen pre-drilled holes make setup simple with Z-brackets, tilt mounts, pole mounts, or ground racking. Pre-attached 4-foot MC4 cables mean less wiring work, so you spend less time installing and more time generating power.

This panel keeps performing without losing power over the years

PID-resistant technology prevents the hidden power loss that quietly degrades cheaper panels over time. Your system maintains its rated output season after season, protecting the long-term productivity and value of your entire solar investment.

A 25-year warranty means Rich Solar stands behind every panel

Rich Solar backs this panel with a 25-year output warranty and a 10-year workmanship guarantee. That kind of long-term confidence is rare  and it means your energy system is protected for decades to come.
