Those little solar garden lights have become pretty ubiquitous in the past few years. They don’t last forever though because the rechargeable batteries in them eventually don’t last through the night after a day’s charging and they ultimately get tossed into the trash. This instructable will show you how to turn those old solar cells into a solar batter which can be used to energize any USB-powered device using some wire, some recycled batteries, some electrical tape, a case of some kind and a couple of chips which will cost you around a Dollar/Euro each.
Please Vote/Favorite/Share/Make this Instructable, see more of my projects at http://justintylertate.weebly.com/ and continue on to the next step.
Step 1: TOOLS/MATERIALS
- 3-6x Flat Top Li-ion Batteries Bulk 2500mAh (can be recovered from taking apart a laptop battery)
- 3x 1.5v Solar Cells (can be salvaged from solar lawn lights)
- 1x TP4056 5v charging circuit (0.27)
- 1x DC Boost Module step up Converter 3V 3.7V to 5V circuit (0.80)
- Some wire
- Heat-shrink insulation
- A project box or other case
- Epoxy
Step 2: CONNECT YOUR BATTERIES
It is really important that you don’t accidentally wire your batteries in sequence or make a short circuit anywhere.
Originally when I was making this instructable, I thought to use 6 Li-Ion batteries, wired in parallel, for storing power however 6 batteries would not fit in my project case so I removed 2 of them.
Step 3: SOLAR CELLS
To attach my solar cells to my project case, I hot glued the seams and epoxied a piece of nylon strap to the back side of them after doing the wiring. This allowed me to sew the solar cells to my project case. Because most project cases will be different, I suggest that you attach your solar cells to the case in the way which provides them the most protection as well as giving them support and allowing for a good angle to catch the solar radiation.
Step 4: CIRCUIT
Now is the time to assemble all of your components; the battery bank, the two circuits and the solar cells.
Following the schematic, you will need to:
- Connect the wire coming from the positive end of the sequence of solar cells to the In hole of the TP4056 5v charging circuit.
- Connect the wire coming from the negative end of the sequence of solar cells to the In- hole of the TP4056 5v charging circuit.
- Connect the wire coming from the positive end of the Li-Ion batteries to the Bat hole of the TP4056 5v charging circuit.
- Connect the wire coming from the positive end of the Li-Ion batteries to the In hole of the DC Boost Module step up Converter 3.7V to 5V circuit (the red circuit board with the USB port).
The following are also detailed in the next step:
- Connect the center pin of the switch to the negative end of the batteries.
- Connect the right pin of the switch to the.BAT hole on the TP4056 5v Battery Charger Circuit Board.
- Connect the left pin of the switch to the.IN hole on the DC step up Converter 3V to 5V USB Charger.
For my project I was able to sew my solar cells to the project case because of the fabric I epoxied onto the back but Probably you will have a hard case so i suggest that you glue and mount all of your circuitry inside of your project case to the best of your abilities in a way that will keep everything safe. A step on installing the USB discharging circuit and the switch will follow in their own step.
Step 5: SWITCH
Flipping the switch will change your charger’s function between discharging and charging your batteries.
Step 7: FINISHED
Congratulations! Now you have a portable, solar-powered battery bank made our of mostly salvaged parts! You can use it to charge your phone, tablet, MP3 player, and anything else which runs off of USB power! Bring it out into the sun and keep your devices running.

re battery issue cont.Note the battery neg are connected to the red lead which is the system positive. I believe that the batteries should show the pos end of the batteries not the ned end fastened to the red pos line.
Let me know if this is correct or not from my observation.
Not to be negative but, not having the time to do something like this and it is a little overwhelming, I have a mini timer that works just as well. Only about 5.
Your mini timer works just as well as what? I don’t see the correlation between this project and a mini-timer.
Excuse me please. I thought I was commenting to the person who couldn’t do anything until they had their coffee in the morning and made some elaborate gadget to start the coffee machine.
No worries, I thought it was probably a misunderstanding/mistake 😉
yeah different instuctable lol
That’s actually kind of funny. And if you read shapri278’s comment in a sarcastic manner it sounds even more hilarious. But I’m sure we all know that this was just a misunderstanding. 🙂
P.S. emoticons would be useful here.
nice idea, but a few things to mention from my side:
If you do connect batteries in parallel, it is VERY important so make sure,that they are all loaded to the same voltage levels. Otherwise the wholebattery pack could light up in fire. The reason of that is that the batterieswill try to instantly balance the load on all cells, whatcould lead to a Rapid charging of a cell with lower voltage. Regarding thedatasheet of the batteries you have linked, the worst case is a max. dischargeof 105A(3x35000mA) from 3 cells to one cell which is supposed to be charged bymaximum 4A.
I would suggest cells with a protection circuit.
The other thing is the loading speed of the solar cells. If you combine 3panels together, you would have about 4,5V and 50mA charging current. Thatwould take about 200 hours for the pack to get charged from zero to full.
Solar Power Bank vs. Traditional Power Bank: Which One is Right for You?
