I am not going to go into detail of how to construct this unit as this is available freely on Youtube and several WebPages. The photos gives great detail of the build.
I will soon do a final test with the solar panel connected and will then post more images and results of the tests. I am quite pleased with the outcome of the Solar Power Supply. I now there is a lot of other components I could have added but I am happy with the build.
