Rollable Solar Powered Battery Charger

PowerFilm Solar Charger

PowerFilm® Rollable Solar Powered Battery Chargers
Ready to use, portable and remote power 5, 10 and 20 watts range.

The World's Most Rollable and Light weight Solar Technology!

Because PowerFilm® Integrated Solar Panels (thin film on plastic) are developed and manufactured with a proprietary roll-to-roll process, by Iowa Thin Film Technologies, they are truly rollable unlike other thin film technologies that are only somewhat flexible.

PowerFilm® solar panels are monolithically integrated which eliminates the need for damage-prone manual connections of individual solar cells. It is made of silicon, a natural resource in abundant supply. PowerFilm® performs well in diverse environments, including hot sun, and does not suffer from wasted over-voltage.

Frequently Asked Questions

How do I know which size I need?
Consult the Application Charge Time Table.

How do I know if it is working?
You can check the PowerFilm® Rollable Battery Charger with a voltmeter.

Will this product drain my battery at night?
No. It has a built-in blocking diode to protect against reverse draining of current.

Can I leave it outside permanently?
The PowerFilm® Rollable Battery Charger can be left outside permanently if maintained properly. It must be properly secured to avoid damage from high winds. Terminals should be kept clean and firmly connected.

What if the product gets wet?
No problem. The product is waterproof.

What if the product goes under water?
Simply wipe the product with a dry cloth and allow the product to dry before use. Avoid having the product completely submerged for an extended period of time.

Can I leave it outside in freezing temperatures?

If I need more power can I connect several of these together? How?
Yes, it is acceptable to connect several PowerFilm® Rollable Battery Chargers in parallel.  Connect using the PowerFilm® Rollable Daisy Chain Accessory* (RA-6). Connect chargers up to a combined output of 20 Amps.

Can I use an extension cord?
You can use the 15 ft. Extension Cord accessory (RA-7) complete with matching marine-grade connectors. Total cord length greater than 30 feet likely will result in reduced power output.

Do I need to disconnect this charger when I start my vehicle or when I recharge the battery with an auxiliary power source?
You do not need to disconnect the rollable solar panel. You need to disconnect any battery charger pack accessory that is connected to the solar panel.

Do I need a charge controller?
A charge controller is used to prevent overcharging. As a general recommendation, a charge controller should be used if the current output of the solar panel, in Amps, is more than 1% of the battery capacity, in Amp-hours. For example, a charge controller would be recommended if the R15-1200 (with 1.2 Amps) were connected to a battery that is less than 120 Amp-hours. Consult the battery manufacturer for complete battery information and recommendations.

How do I clean the product?
Use a damp cloth with a mild soap solution.

Solar Powered Battery Charger Technology

Integrated Technology Package
Because PowerFilm® integrated solar panels (thin film on plastic) are developed and manufactured with a proprietary roll process, by Iowa Thin Film Technologies, they are truly rollable unlike other thin film technologies that are only somewhat flexible. PowerFilm® solar panels are all monolithically integrated which eliminates the need for damage-prone manual connections of individual solar cells. PowerFilm® is made of silicon, a natural resource in abundant supply. PowerFilm® is Cadmium Free, unlike some other solar technologies, and performs well in diverse environments, including hot sun, and does not suffer from wasted over-voltage.

Ultra Rollable
PowerFilm® products are ultra rollable because they are manufactured on a roll up to 2400 feet long, using the proprietary roll-to-roll manufacturing technology platform of Iowa Thin Film Technologies. Iowa Thin Film Technologies is the first and only company in the world selling solar products manufactured on a true roll-to-roll process using a plastic substrate.

PowerFilm® products are monolithically integrated which eliminates the need for damage-prone manual connections of individual solar cells. PowerFilm® products are constructed using a durable polymer (plastic) substrate.

Easily Integrated
Several features enable easy integration: Paper thin low profile; Ultra flexibility allows conformity to shapes; Complete product design eliminates need for unsightly bolt-on frames.

Fabric Integrated
Integrated with a fabric backing for enhanced product functionality.

Constructed using a proprietary combination of thin and lightweight materials.

Environmentally Friendly Profile
Cadmium Free! (Other solar technologies such as CIS, CIGS, and CdTe contain cadmium which is considered an extremely toxic metal by the Department of Labor.) If comparing products, check to be sure they are Cadmium Free. Primary element used in PowerFilm® is silicon, a natural resource in abundant supply.
