USB Solar Grid complete. From left to right:
- PowerFilm R-14 solar roll - 14W
- Tekkeon 3450 MP - 55W battery
- iPhone 3G - 5W battery
- iPad 2 -25W battery
5 hours of full sunlight on the PowerFilm R-14 generates about 70W of power (5hrs x 14W/hr = 70W), which will fully charge the Tekkeon 3450 MP battery. The fully charged Tekkeon 3450 MP will charge both the iPhone & iPad twice from a 10% battery state.
This is a "proof of concept" grid for small and mid sized USB devices like the iPhone & iPad. The "Big Idea" is to work out the logistics of a PV system that would run a small house on STJ (including AC).
