When we set out to design our solar roof kits for golf carts, we tested a variety of solar panel types to find the best solution. Many people ask why we use rigid solar panels instead of flexible ones. The answer is simple: performance, efficiency, and reliability.
Flexible Solar Panels: The Trade-Offs
Flexible solar panels are often marketed as lightweight, thin, and easy to install. At first glance, they seem like a convenient choice for applications like golf carts. However, during our initial testing, we found several key issues:
-
Lower Power Output than Advertised: Despite being labeled at specific wattages, flexible panels consistently delivered far below their advertised ratings. This left carts underpowered and unable to sustain meaningful range.
-
Insufficient Charging for Golf Carts: Golf carts require consistent, reliable charging to extend their range. The flexible panels simply could not deliver enough energy to keep a cart ready for daily use.
-
Durability Concerns: Flexible panels are prone to wear, bending, and delamination over time. When exposed to outdoor environments (heat, UV, and vibration from driving), their lifespan is noticeably shorter.
Rigid Solar Panels: The Superior Choice
Rigid solar panels, by contrast, have proven to be the industry standard for long-term, reliable power. Here’s why we chose them for our kits:
-
Industry-Leading Efficiency: Our rigid solar panels operate at 21% efficiency, which is among the best available. This means more energy harvested from the same amount of sunlight.
-
Reliable Wattage Output: Unlike flexible panels, rigid panels consistently deliver the wattage they’re rated for. That reliability is crucial for powering golf carts day after day.
-
Durability and Longevity: Built with tempered glass and reinforced frames, rigid panels withstand the sun, rain, and vibration from driving with ease. They maintain performance year after year.
-
Superior Range Extension: With a rigid 370W or 500W panel, a golf cart can gain up to 20 extra miles of range per day—something flexible panels could never achieve in our testing.
Why It Matters for Golf Carts
Golf carts are unique compared to other small solar applications. They need consistent, high-wattage charging to reduce plug-in time, extend range, and support fleets that are in constant use. A few watts of trickle charging isn’t enough—courses and owners need a dependable solution.
By using rigid, high-efficiency solar panels, we’re able to deliver:
-
Extended daily driving range
-
Reduced reliance on electrical outlets
-
Long-term reliability and cost savings
-
True performance that matches our claims
The Bottom Line
Flexible solar panels may look convenient, but our testing proved that they fall short in real-world performance—especially for golf carts that demand dependable charging. That’s why we chose rigid solar panels: they’re efficient, durable, and capable of delivering the power our customers expect.
When it comes to keeping your cart moving, reliability matters—and rigid panels deliver.
