Rigid panels are stable and efficient, making them excellent for fixed installations, whilst flexible panels are versatile and durable, making them suitable for curved surfaces or portable setups.
What is the difference between flexible and rigid solar panels?
As the name suggests, flexible solar panels can bend, while rigid ones are stiff to the touch. Traditional solar panels are constructed with a rigid aluminum case and covered with durable tempered glass, allowing light through and protecting the photovoltaic cells inside.
These rigid panels are thick, heavy, and less portable. Flexible solar panels comprise a combination of monocrystalline cells and laminate, allowing these panels to mold to curved or angled surfaces. They are ideal for boats, RVs, and roofs that can't accommodate the flat surface required for rigid solar array frames.

They are ideal for boats, RVs, and roofs that can't accommodate the flat surface required for rigid solar array frames. However, they're also typically less durable.
How efficient are flexible solar panels?
Most mass-market flexible panels currently max out at around 15-18% efficiency, while premium rigid panels push 20-22% efficiency, converting more of the sun's rays into useful energy. To meet a given energy demand, more flexible panels must be deployed to compensate for their lagging efficiency metrics.
Are flexible solar panels better than non-Rack solar panels?
Proper airflow and cooling are essential to maximize flexible panel productivity on hot days, which is more challenging with non-rack installations. Rigid panels lose some output but are generally more temperature tolerant. In terms of sizing, flexible solar panels are restricted to relatively small form factors of around 200 watts per panel.
This flexible surface is more prone to scratching or gouging from overhanging branches when driving into heavily wooded areas. In general, the flexible panels are less durable, but Renogy offers the same 5-year warranty on workmanship & 25 years on power output as their rigid panels. DIY Ease of Installation (Flexible)
