Solar Charger compensate economic and ecological terms. It 's always better when you consider that not everyone uses electricity to recharge the batteries, if you use the power of the sun.
What you need:
1) AA Battery Holder
2) 9-volt battery clip (this is to connect to the battery holder)
3) 8 x Solar Cells 0.5 V, 20 to 50 mA in full sun
4) IN5818 Schottky Diode
This is a very simple circuit thatdoes not provide rules. All you have to do is to disconnect the battery when fully charged.
The Schottky diode prevents battery recharge 'flows through the solar cells, if no charge is left. Schottky diodes have the advantage, not to undermine much of the power of our solar cells, maximizing the amount by which the batteries will be delivered.
If you live in a climate where the sun is a rare pleasure, and is often cloudy happen, you might want toto experiment with a couple of additional cells in series to increase the power produced.
The construction process isn't difficult at all. There are wide arrays of cases available that are suitable for housing such projects. If you can get housing with an integral battery holder, you find it will make neat work of housing the project.
House the cells in a way that they are shaded and well protected from the sun. Take note that If the cells get overheated, their electrolyte leaks. That will damage the cell and making a mess.
