Solar-Charged electric bicycle Howto/Guide

For a long time now i've been playing around with solar panels.
Thanks to Steemit, and well, you, Steemers, I was able to move ahead a lot faster with it lately, and I have now completed solar-charging my electric bicycle.

The system will work for any 36-48v bicycle battery, and while not optimal, it does an excellent job extending your range or simply charging your bike while it's parked outside.

What will you need:

• 3 of those 10W 12V Panels. Those are good Watt-per-cost value: http://s.click.aliexpress.com/e/Jmaqjqr
• a 12V-24V to 48V Step-up converter, get one here: https://www.aliexpress.com/item/New-Waterproof-12V-to-48V-2A-96W-DC-to-DC-Boost-Converter-DC-DC-Step-Up/32299592894.html?spm=2114.13010608.0.0.geqk1j
• A Charge controller that can take up to 48V, like this one: http://s.click.aliexpress.com/e/ZjuzFYZ
• Diodes, I got those: http://s.click.aliexpress.com/e/VBiqbQ7

Wiring

• Wiring in our case is rather simple, you want to parallel-connect all 3 panels so that you will have 12V 30W Total, use a diode between them (if your panels don't have one built in in its connector-box on the back side).
  Connect the panels to the input of your 12-48 convertor.
• You should now have 48V coming out of the output pins. Connect those to the solar panel pins on your connector.
• Use two wires from the battery pins on your controller, to your battery. Your bike battery may explode if wrongly connected, and might burn your contoller if polarity is wrong.

In my setup, I used 3 panels but ofcourse you can use more, as long as you connect them in parallel.
My setup manages to add 2 volts to the battery in a sunny day, so most of the time I don't have to charge it in the electricity at all.

If anyone needs help setting this up, let me know :)
