Ecoflow Heat Guard Solar Film (For Model Y)

Overview

The EcoFlow Heat Guard Solar Film for Model Y is a tailor-made solar solution designed for the Tesla Model Y roof. It combines solar energy generation with thermal insulation in a low-profile design that integrates neatly with the vehicle.

With 290 W output, N-type TOPCon cell technology, and a flush-mounted fit, this solar film is built for drivers who want to make use of roof-mounted solar power for compatible EcoFlow portable power stations while maintaining a clean appearance and no known aerodynamic impact.

Key benefits of the EcoFlow Heat Guard Solar Film for Model Y

• Rated output of 290 W for solar charging use
• Designed for the Tesla Model Y roof
• Helps reduce cabin heat with integrated thermal insulation
• Supports portable power stations such as EcoFlow DELTA 2 or DELTA 3
• Flush-mounted, low-profile design
• IP68-certified for resistance to water, dust, and sand

How it works

The solar film captures sunlight from the vehicle roof and converts it into electricity that can be used to charge compatible portable power stations. According to the product information, it is not suitable for charging the Tesla main battery.

This makes it a practical option for off-grid travel, camping, and outdoor use where extra energy is needed for appliances, devices, or portable power storage.

Thermal comfort and energy efficiency

Beyond solar generation, the EcoFlow Heat Guard Solar Film is also designed to improve cabin comfort. The product information states that it can reduce interior temperature by more than 10 °C and help lessen the load on air conditioning.

It uses Air Gap Technology for additional insulation, which may support better thermal control when the vehicle is parked in hot conditions.

Technology and performance

Advanced solar cell design

The film uses N-Type TOPCon monocrystalline silicon cells with an efficiency of at least 24.8%. This cell technology is designed to deliver strong performance in a compact surface format.

Flat, integrated installation

The low-profile design is intended to sit flush on the vehicle roof. EcoFlow describes the product as having zero drag, meaning it is designed not to affect driving range through added aerodynamic resistance.

Installation and compatibility notes

Installation is carried out using 3M™ VHB™ adhesive tape, described as residue-free. The product also uses an ultra-flat FlatLink MC4 cable for routing.

For connection, the solar film uses an XT60 connector. It is intended for use with EcoFlow power stations and the EcoFlow ecosystem, including monitoring through the EcoFlow App and integration with EcoFlow Oasis where supported.
