4 Way Solar, a brand-new Colorado-based RV solar company, just released its first product called the 4-Directional Solar Tilt System. Designed for RVs, truck campers, vans, and other mobile platforms, the mounting system helps owners harvest more solar during winter when the sun is at its lowest point in the sky.
“We built 4 Way Solar for real-world campsites—where shade, tight pads, and odd orientations are the norm,” said Neil Kauppila, mechanical engineer and founder of 4 Way Solar. “Four-direction tilt means faster setup, better alignment, and more usable power when flat, rooftop mounts fall short.”
4 Way Solar’s new solar tilting system is simple yet ingenious. The system consists four fixed bracket assemblies that work in conjunction with two removable and adjustable stilts. Unlike traditional mounts that lock users into a single tilt direction—or no tilt at all—4 Way Solar’s directional tilt system is the only system that allows panels to tilt in four directions: north, south, east, and west. This flexibility enables users to optimize panel alignment even when the campsite layout is fixed.
“When COVID hit in 2020, we took to the road to work in a 26-foot RV,” Kauppila said. “With limited rooftop real estate and batteries that never seemed to stay topped off, we kept running into the same problem: we had enough solar on paper, but not enough usable power in real campsites—especially when winter sun angles were low and the rig had to be parked wherever the spot allowed. As a mechanical engineer, that challenge felt solvable. I knew the issue wasn’t always panel size, it was alignment. Flat-mounted panels and one-direction tilts don’t help much when the sun is low and your campsite points the “wrong” way. So I built a mount that let our panels tilt no matter how we were parked—north, south, east, or west—so we could actually face the sun without moving the entire rig.”
Tilting RV rooftop solar panels towards the sun during winter months offers a huge benefit. Doing so can increase an RV’s energy production by up to 40 percent compared to flat, rooftop-mounted panels, thus helping owners obtain a faster battery charging rate.
4-Way Solar’s new tilting mounting system is well-made. Constructed of an aerospace-grade aluminum (6061-T6), the unit weighs only 3.25 pounds, yet offers a hefty weight rating of 50 pounds that can endure winds of 30 mph when tilted or 80 mph when stowed. The roof clearance is only 2 inches high when stowed.
“The hardware has been meticulously iterated with one goal in mind: make it something you’d trust on the road, in real-world conditions, not just in a garage. Today’s 4 Way Solar kit is durable, simple, and designed for the daily realities of truck campers, RVers, van lifers, and off-grid travelers—tight campsites, wind, vibration, quick setup, and the constant need for dependable power. We built it for people who want to park where the views are, stay longer, and worry less about battery math—and we’re genuinely excited to finally offer it to the Truck Camper Adventure community,” Kauppila said.
4 Way Solar’s new solar tilting mounting system debuted at last week’s 2026 Truck Camper Adventure Quartzsite Rally and was featured on Bob Eckhart’s Ford F-550-Bigfoot 2500 10.4 Rig. One 4 Way Solar system was raffled off to Leslie Williams who attended the big, outdoor event in her GMC 3500-Lance 1121 truck camper.
Two 4 Way Solar tilting kits are offered: a 30-inch kit for $95.00 and a 50-inch kit for $115.00. Each solar panel in your camper’s rooftop solar system will need a complete kit.

About 4 Way Solar
Based in Montrose, Colorado, 4 Way Solar designs and manufactures innovative solar mounting hardware for mobile and off-grid power systems. Its flagship 4-direction tilt mount helps users capture more energy from the same panels—especially when sun angles and campsite orientation work against fixed installations.
I continue to be very pleased with this system. Currently boondocked in southern Utah, and power is no longer the limitation for how long we can stay put without a long drive to recharge via our DC/DC alternator driven charger.
