Feature:
1. Keep your vehicle battery topped up at all times. Your battery will charge every time your vehicle is parked in the sun. Perfect for the overlander or camper who wants to power devices without worrying about draining their battery. 
2. Prolongs your battery life. The solar panel will give you longer overall battery life by tending it constantly during periods of sun exposure. 
3. Emergency engine starting device.  If you ever manage to completely drain your battery. The solar panel will start the vehicle up again in as little as 30 minutes depending on sun exposure.  Very efficient and great back up if you want to be off the grid.
4.Decreased hood glare. Due to it's light absorbing properties the solar panel creates a surface with very low reflectivity across the hood of the vehicle, the decreased glare while driving. That means constant charging regardless of sun angle.

5. The optional Plug-and-play MPPT solar charge controller, has been pre-wired with fuses, terminals, and connectors. The Solar charge controller is based on common negative design and advanced MPPT control algorithm, with intelligent protection against reverse polarity, overcharging, short-circuit, and reverse current.

6. The optional but highly recommended custom cut vinyl base sheet protects the underlying vehicle paint from damage. The Solar charge controller is based on common negative design and advanced MPPT control algorithm, with intelligent protection against reverse polarity, overcharging, short-circuit, and reverse current.

Lensun 50W (20W+30w) ETFE Flexible Solar Panel Feature

1. Solar cell: Grade A PERC Monocrystalline solar cells with much higher efficiency and more durability than other mono solar cells.
2. Premium EFTE Film: This film features superior light transmittance and weatherproof performance, and is also heat, corrosion, and UV resistant. ETFE also has self-cleaning abilities, ensures the best performance day after day.
3. Backboard: Durable fiberglass substrate backboard, better heat dissipation than PET backboard which ensures a long lifetime. ETFE film and fiberglass backboard can withstand extreme environmental conditions, maintenance-free for years.
4. Ultrathin & Lightweight: At only 3mm thick, the solar panel is powerful, waterproof, lightweight(60% less than the conventional solar panels), durable, and highly resistant to the harsh operating conditions of a marine environment.

Installation:

Can be fixed by 3M tape or sikaflex glue(Note: 3M VHB tape and silicone need to be purchased by yourself!). We highly recommend install the solar panel with our specific vinly decal, the vinyl decal sits under the solar panel and protect the hood paint. The vinyl decal install on the hood in the same way that traditional hood vinyls or automotive vinyl stickers are applied.

The installation must be done in a dry environment between 18° and 35°C   (64° and 95°F). In cold conditions, the solar panel will not have enough flexibility to form to your hood, and the adhesive will not properly bond. Your installation will FAIL.
