AWNLUX SA5900 Full Cassette RV Solar Awning

Awnlux SA5900 Full Cassette Solar RV Awning — CIGS Thin-Film

The most common question buyers ask before purchasing a solar awning: "Is it worth it if I mostly camp under trees or in cloudy weather?" For a standard silicon solar panel, the answer would often be no — silicon drops to around 15% output under 30% tree shade. The SA5900 uses CIGS (Copper Indium Gallium Selenide) thin-film technology, which behaves fundamentally differently under partial shading. Under the same 30% tree cover, CIGS retains 72% output. On a cloudy day, CIGS holds around 45% output compared to silicon's 25%. The SA5900 is practical in the mixed light conditions that real campsites provide, not just in an open parking lot in full sun.

The SA5900 is the full cassette version of the Awnlux solar awning range. The aluminum cassette shell fully encloses the CIGS solar fabric, roller tube, and mechanism when the awning is retracted — protecting the solar fabric from UV degradation, road debris, and mechanical damage during travel. This matters more for solar fabric than for standard vinyl: CIGS thin-film is durable but benefits from the additional protection of a sealed shell when not in use.

The CIGS solar fabric rolls around a roller tube with a minimum reel diameter of 4cm and is flexible enough to bend 360° without cracking. This is a fundamental advantage over rigid silicon panels, which develop micro-cracks under the repeated deployment and retraction cycles of an awning. The SA5900 has been verified through 3,600 fatigue test cycles — equivalent to nearly daily use over 10 years — with stable electrical output confirmed throughout. Awnlux provides a 5-year 80% power efficiency guarantee on the CIGS solar fabric.

Both manual and motorized control versions are available. The motorized version includes a built-in crank handle backup port for manual closure if motor or battery power is unavailable. The maximum size (400cm × 250cm) produces up to 1,080W peak and approximately 4.5 kWh of usable energy per day in good sun conditions — sufficient to run a 12V compressor fridge, lighting, USB charging, and a fan simultaneously without drawing from stored battery capacity. Output connects via standard MC4 DC connectors and is compatible with most MPPT controllers and 12V, 24V, or 48V battery systems.

For OEM partners, the SA5900 is available with custom frame colors, private label branding, and tailored sizing within the 200–400cm width range.

Q1: Is a solar awning worth it if I mostly camp under trees or in cloudy weather?

This depends on your solar technology. For standard silicon panels, partial shading causes a disproportionate output drop — 30% tree cover can reduce silicon output to 15%. The SA5900 uses CIGS thin-film, which retains 72% output under 30% tree shade. On a cloudy day, CIGS holds around 45% output (vs 25% for silicon). If your campsites have trees or variable weather, CIGS makes the solar awning viable where silicon would not.

Q2: What is CIGS and why is it different from regular solar panels?

CIGS (Copper Indium Gallium Selenide) is a thin-film semiconductor technology. Unlike silicon panels, which use rigid cells connected in series, CIGS is a continuous film. Shading or damage to one area only affects that area — there is no cascade failure and no hot-spot effect. CIGS is also flexible enough to roll around a 4cm reel diameter, making it suitable for a retractable awning where silicon cells would crack.

Q3: How much power does the SA5900 produce per day?

Peak output depends on awning size. The 400cm × 200cm configuration (maximum size) produces 700W peak. In good sun conditions with 6 peak sun hours, that translates to approximately 3.6–5.4 kWh per day. The 300cm × 200cm produces 465W peak, or approximately 2.6–3.9 kWh per day. Real output varies with sun angle, shading, and weather. CIGS significantly outperforms silicon in less-than-ideal conditions (see the 7-scenario comparison table above).

Q4: Does the SA5900 include an MPPT controller?

No. The SA5900 outputs standard MC4 DC power, which connects to an MPPT controller that you source separately based on your battery type and voltage. Contact our team with your battery chemistry and voltage for controller specification recommendations.

Q5: What is the difference between SA5900 and SA5700?

SA5900 is a full cassette awning — the CIGS solar fabric is fully enclosed in an aluminum shell when retracted, providing the best protection for the solar fabric during travel. SA5700 is a roll-out awning — the solar fabric is exposed when retracted. SA5900 covers 200–400cm wide. SA5700 covers a wider range (up to 21ft / approx. 640cm). Both are available in manual and motorized versions. SA5900 is recommended when fabric protection during travel is a priority.

Q6: Can the SA5900 solar fabric replace the fabric on an existing standard awning?

No. CIGS solar fabric weighs approximately 1.3 kg/m² — three to four times heavier than standard PVC vinyl. Standard awning frames are not designed to carry this load. The SA5900 requires the full Awnlux solar awning frame system. If you have an existing Fiamma or Thule wall bracket, contact us — a 3-in-1 bracket adapter may allow installation without new wall drilling.

Q7: What wind conditions is the SA5900 safe in?

The SA5900 is rated for safe use up to Force 5 (Fresh Breeze, approximately 29–38 km/h sustained). Retract in winds above Force 5 or when conditions are developing unpredictably. The motorized version is compatible with an optional wind sensor for automatic retraction. The manual version retracts using the crank handle.

Q8: Is the SA5900 certified for European market sales?

Yes. The SA5900M is covered by four independent certifications, all issued by UDEM International Certification:
