make modular, pocket-sized solar panels  -  polycarbonate sheet cut to size
Have you ever been outside, the phone is dead?
Have you ever thought about making your own solar panels and charging your phone or electronics project? Now you can!
The cost per group is $1.
Material 25, 0-0. 5V at 400-
1000 mA depends on the load and lighting.
The panel can be connected via a magnet and can be dynamically reconfigured to provide a different voltage and current. Portable devices that can be used to charge your phone when you are camping or on grass somewhere.
It's easy for anyone to make with the tools you might have around the house.
For alternative guidelines, please check the github page for the project.
For tool material for price breakdown, see the github page on the material for this project.
Statement: solar cells are very thin and prone to rupture.
Be careful.
For 52x76mm solar cells, cut your paper to 65x90mm (6. 5 x 9 cm).
For each solar panel you plan to make, cut two polycarbonate rectangles of 65x90mm and two EVA rectangles.
Cut copper tape 7 cm long.
Apply it to the white line and stick it below.
Make sure there is a gap between the end of the tape and the end of the unit (
See at the bottom of the image)
Turn over the solar cells.
Repeat for the back of the solar cell.
Make sure there is a gap between the end of the tape and the end of the unit (
Seen at the bottom of the solar cell)
Remove a piece of polycarbonate and remove two protective films from the plastic.
Remove the protective paper from one EVA sheet.
Place a piece of EVA entirely on the top of the pc with a bump up.
Then place the solar cell assembly on it.
Carefully place the solar cells in the center of the polycarbonate/EVA sheet.
Remove the backing from the remaining polycarbonate and EVA sheet.
Now, place an EVA board with a bump down on the assembly.
Place the remaining polycarbonate sheet on top of EVA.
Check if your solar panel meets the following order from bottom to top: polycarbonate, EVA (bumps up)
Solar cells, EVA (bumps down), Polyester.
Also make sure your copper tape is sticking out from both sides of the panel.
Place the Assembly between sheepskin pieces of paper to keep the press roller clean with the melted EVA and copper tape adhesive.
Without interfering with the position of the solar cell in the Assembly, carefully place the assembly in the laminating press in the direction shown.
When using these magnets, the right direction is important to them.
Mark one side of the magnet.
Now do it in the rest, so that when you stick the two magnets together, the marked side always draws the blank side.
As shown in the figure, place a magnet facing up on the panel.
Fold the copper tape now.
Make sure it is closely aligned with the 90 degree angle of the magnet.
Now open the panel and add another magnet in the position shown.
The mark face of this magnet should be down.
Fold the copper tape now.
Make sure it is closely aligned with the 90 degree angle of the magnet.
If you have a multimeter, please check the voltage and current output of the new solar panel.
Make sure you have a bright light on your solar panel.
It should have a voltage of 0.
55 V, and the current is between 0. 4A and 1.
Depending on how bright your light is.
These solar panels can be stacked for ease of transport due to design reasons.
Your panel is about the size of a deck.
I bought this card bag at tap plastics.
If you want to charge your phone with USB for 5 v, you have a lot of options: 6-12 panels (3-6V)
You can use boards like Minty Boost or other 3 v to 5 v Boost converters to charge your phone.
There are 12 panels (6V)
, You can use the solar lithium polymer charger of Adafruit to charge the battery and mobile phone very effectively (
A 5 v low voltage difference linear voltage regulator may be required). With 12-46 panels(6V-23V)
, You can use the buck converter and my other guide to charge your device efficiently.
You can run Arduino by connecting the positive and negative poles of 12 solar panels to the bucket-
Arduino Jack.
