A Solar Power Assisted Mobility Scooter
A while ago I received a call from Arnie Driver in South Australia. He’s into his nineties but is still very active though he can’t walk far these days so he uses a mobility scooter, also known as a Gopher. The travel range of the Pride Legend scooter, powered by a 35 amp hour battery, needed to be extended and solar power was the obvious solution.
Steca 12V/24V 6 amp solar regulator to regulate the battery charge.
Two on/off switches, one to isolate the battery and the other to isolate the solar panels.
The two 12 volt solar panels are connected in series to double the voltage to 24 volts and then connected to a 24 volt Steca solar regulator which then controls battery charging.
Aluminium Angle 40mm x 40mm x 3mm usedTwo 590mm end braces joining the two panels, one at the front and one at the back across the width of both solar panels, fixed to the solar panel frame with self tapping screws. The flag is attached to back one.
Two 660mm horizontal braces fixed to the end braces, one under each of the solar panels, fixed to the solar panel frame with self tapping screws.
Be careful when using self tappers in aluminium, don’t over-tighten or it will strip the thread.
Two 460mm vertical braces bolted to the back of the seat backrest placed 60cm apart, the width of the two panels and fixed with self tappers to the horizontal braces.
Two 550mm diagonal braces bolted to the vertical backrest braces and horizontal braces using 6mm nuts and bolts.
