Voltaic Generator Solar Laptop Charger

The solar panel is waterproof, scratch resistant, and UV resistant. It uses high efficiency (20%) monocrystalline cells.

The panel generates up to 15 watts of power which will recharge the Voltaic battery from approximately 5 hours of direct sunlight, see typical charging times listed below.

The substrate is an aluminum / plastic composite, specifically designed to be strong and lightweight. They can easily stand up to typical outdoor use. Even if the panel is broken, which would likely take a conscious effort, it can easily be removed and replaced.

The coating is a flexible polymer which can tolerate over 5 years of exposure to direct sunlight. The surface is flexible to help resist scratching. Scratches will actually melt out when exposed to the sun. To allow maximum light to reach the cells, keep the panel surface clean using a soft cloth and alcohol or warm soapy water.

Note: For maximum power output, angle the panels towards the sun. When the panels are in direct sunlight but not angled towards the sun the power declines about 20%. When they are angled away from the sun the power drops off 80-90%. Dirt and scratches on the face of the solar panels will reduce the amount of light hitting the solar cells and reduce the power generated. To clean them use a damp non-abrasive cloth.

*Charge times may be increased in cloudy weather, high temperatures, or where panels are not angled towards the sun. Note: this refers to the amount of time in the sun required to generate enough charge to fully charge the listed device. It may take longer for that charge to flow from the Voltaic battery to the device. A typical cell phone takes 2 hours to charge even from AC power, it will likely take that long for that charge to flow from the Voltaic battery to the cell phone. However one hour in the sun should be enough time to generate and store that charge in the Voltaic battery.
