It’s the 23rd of March. We’re into Spring in Europe and the sun has just moved above my neighbor’s house. According to the local weatherstation there’s 365 W/m2 hitting ground level. I’m getting 1 Watt out of my 4W Changers Maroshi panel.
One of the problems of powering laptops and tablets by solar is that you need a buffer between the module and the device in order to protect the device against wild voltage variations. Often that’s a lithium ion battery pack. In many cases the battery pack doesn’t take full advantage of low-current situations at the start and end of the suns journey across the sky. Diamond Creek is a module in development at Intels labs that solves this problem.
