Introduction: Solar Panel Small(2.01volt in Low Light)

Picture of Solar Panel Small(2.01volt in Low Light)

Small solar panel made from various separate panels made with minimum materials.
Basic small panel for charging a few AA batteries over the span of 3/4days of sun,(A rarity in the the uk however just in case i made a small panel)

Will probably expand this panel so it is a temporary design and the rest of the A4 size panel will be filled with mixed cells, obtained form old toys solar garden lights even calculator panels would add a tiny amount of power,soldering on glass panels takes some practice but can be done.

(2.01 VOLTS IN LOW LIGHT CONDITIONS "TESTED") More then enough to charge your battery even on a dark day..even from indoor household light! harvest some back even at night..why not.. (SEE VIDEO BELOW)

Step 1: Parts Needed

Picture of Parts Needed

x5+. Solar Cells. (scavenged from solar garden lights etc)
x1. A-4 sheet of Plexiglass/Perspex.
x2 Colors of electronic wire. (optional just helps indicate polarity)
x1 A4 Size piece of Cardboard. (for the temporary backing)
x1 Multimeter voltage & battery tester. (set mine to read 10v DC for reference)
x1 Blocking Diode. (Scavenged from an old TV unknown rating or type not pictured)
x1 Glue Gun & Glue.
x1 Soldering Gun/Iron & Solder.
x1 Helping hands. (for holding the panels while you solder the connections)
x2 Batteries for charging, (mine are recycled from old solar lights)

 

Step 2: Construction

Picture of Construction

Simple construction collect all your cells and solder the connections with wires noting the polarity,Test each panel after you have soldered the connections with a small light,i used an x3 led light and old recycled mobile battery to power it,Once done now link them in series positive to negative,positive to negative,and carefully place them on a pane of some kind,place under a large desk lamp and test again to make sure it works,now solder the blocking diode as so it is removable at a later date for use in other/larger panel etc,see picture,and attach to the end of the wire on your panel once done..

Easy part now make a cardboard backing and paint it up in whatever desired colour or not,and glue all the panels in place on it,then the A4 plexiglass/perspex in place ontop.Retest it see next step.
 

Step 3: Testing and Uses.

Picture of Testing and Uses.

Test the whole thing.
(It works fine as you can see lamp was not that bright nor powerfully,would get much more power on a sunny day,in summer)

Uses pretty obvious to charge a few AA batteries etc,in a few days of strong sunlight,and make all of your electrical experiments solar powered.

How do you charge the battery is there any regulator?
