Product Overview

For many vehicles-especially EVs, fleet cars, and vans-battery drain is a real issue when parked or operating auxiliary systems.

This automotive CIGS flexible solar panel is built to solve that problem.

It integrates directly onto the vehicle roof, generating power throughout the day to support:

battery maintenance
ventilation systems
telematics
refrigeration units

No fuel, no extra wiring complexity, and no impact on vehicle structure.

Key Capabilities

Works even when the car is partially shaded:

Maintains output under roof racks, antennas, or uneven sunlight conditions.

Designed for real driving conditions:

Handles vibration, temperature fluctuation, and long-term outdoor exposure.

Fits curved roofs without structural changes:

No drilling required, no impact on aerodynamics.

Lightweight enough for OEM integration:

Adds minimal load, making it suitable for both EV and fuel vehicles.

Where it is actually used

This type of system is already used in:

EVs for auxiliary battery support
Fleet vehicles to reduce idle energy loss
Refrigerated vans to support cooling systems
Off-road and RV vehicles for off-grid power

Why not traditional solar panels?

Rigid panels don't work well on vehicles. They:

Can't fit curved surfaces
Are prone to cracking under vibration
Reduce aerodynamic performance

Flexible CIGS panels solve these issues by adapting to the vehicle instead of forcing structural changes.

Business Value

For your business, this means:

fewer battery failures in parked vehicles

reduced maintenance cost for fleet operations

added product value for automotive customers

new selling point for EV and retrofit markets

Proof & Reliability

Tested under continuous vibration and temperature cycling
Maintains stable output in real driving conditions
Certified for international compliance (CE, RoHS, REACH)
Field-tested in vehicle applications

FAQ

Q: Can solar panels really work on moving vehicles?

A: Yes. Flexible panels are specifically designed to handle vibration and changing light conditions, making them suitable for real driving environments.

Q: Do automotive solar panels help extend EV range?

A: They don't replace charging, but they can support auxiliary systems and reduce battery drain, which indirectly improves efficiency.

Q: Is installation complicated for vehicle integration?

A: No. Most systems use adhesive mounting and require no structural modification.
