Sol-a-tron - DIY solar charger
Build your own solar charger!
This unit has a USB output to recharge phones and other small USB devices.
There are two 1Wp solar panels which recharge a bank of three AA NiMH rechargable batteries.
A DC-DC converter ensures regulated 5V for the USB connector output.
Kit includes 2 x solar PV modules, laser-cut case and rechargable batteries.
In the UK the batteries will recharge in around one day during an average summers day. This depends upon the solar resource available.
This is a reasonably simple kit which requires some soldering and a few fiddly connections. It should take 1-2 hours to build. Not suitable for under 12 years old.
