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.
I’ve just finished a full review of the Toshiba Encore WT8 Windows 8.1 Tablet. As expected it’s incredibly efficient, and perfect as a solar-powered PC. You can do everything on this. From web browsing to video editing to Office work with a full keyboard and external monitor.
Using the sun to power consumer electronics is horribly inefficient and expensive but as technology advances, the process gets a lot better. PCs are running in 5W now compared to over 10W just 5 years ago. Screen technology is getting more efficient and the solar equipment used to collect and store the energy from the sun is getting better. Solar panels are still expensive and inefficient but Changers have put together a solution that’s intelligent, easy, fun and not too expensive. It doesn’t quite deliver what it should and it’s not up to powering any sort of PC solution but it’s fun and easy to use for smartphone-like charging operations.
The Changers solar panel, power pack/data logger and community is an interesting concept and, I think, a well designed product. Lithium battery charging and solar power don’t fit together easily but when they do you have the potential to get a powerful and lightweight solution. The equipment arrived today, it’s in working order and over the following weeks i’ll be doing some testing.
The consumer-focused solar charging sector has been damaged in recent years by the influx of cheap China-manufacture red solar chargers that really don’t do what they say. This solution from Changers.com is in a different league. I had the pleasure of speaking to the founders today and got a bit of tech talk in. What I found out got me excited about doing another solar computing tour because the intelligent power pack is one of the best i’ve seen. I want to pair it with the Lenovo Lynx PC. Clovertrail is perfect for travel computing and the Lynx even charges via micro USB. In theory, one 4hr charging session will charge about 60% of the Lenovo’s internal battery for about 4hrs of work. 1hr charging for 1hr computing is a real groundbreaking achievement, if it works.
