Honestly, I don’t get this solar thing.
It’s heavy, low powered, and will contribute serious drag.
Forget it and move on to more functional solutions – like planning accordingly to spend the night where you can recharge off the grid.
Don’t go overboard and shoot yourself in the foot by purchasing a huge power supply that uses 2 kw! I was running with 63V 130 Ah which could carry me an average of 160 miles/260km per day. Recharged using two Meanwell HRP-600
(24V + 48V) in series; the total current draw was about 1 kw which is well below the limits of common household circuits. It means that you can recharge in the motel room or at a gas station or electrified rest stop. This charging assembly weighs less than that solar panel, less than any gas charger, and you can use it 24/7. I recharged during my sleep.
- Buy enough batteries for you to complete the most challenging day.
- Make sure you can pedal your ebike fully loaded; it’s important in case you run low on power.
- Ride in the direction of the wind. I did my 2011 WA-CA loop clockwise when it would have been better going the other way.
Most people do not understand how difficult it is to do 100 miles/160km or more every day! For June, train now for progressively longer rides each weekend, then train two or three days in a row. It's good for the spirit and for the ebike; figure out the weak links early. Get your diet sorted.
Safe travels, KF
