Solar Powered Electric Wheelchair Answered

I would like to put a Challenge out there for anyone to come up with.

You see, I am in a wheelchair and I would love to go hiking with my son, but my chair can only go so far before it needs to be plugged back into a socket. I hate this, because it keeps me from going most places I want to go outdoors. But it dawned on me that if I had a Solar Powered Option to my chair, nothing could hold me back from being outdoors again. Ok yah,  it would help if I could redesign the platform & wheels too, but that's not the most important part... I NEED POWER.

So, if anyone feels like taking on a new challenge and you are into Solar Power perhaps you could help me in this way.

Thank You for your time in reading this, I hope to plant seeds of inspiration with all of you!

May Love Light Your Way, Blessings!

You could have a solar powered wheelchair, it just wouldn't be very practical or good for "hiking." There are solar powered cars. You could build one or have one built and use it in open spaces or on a wide track.

If you're looking at driving your chair directly off solar power, I am afraid you will probably be disappointed - going off-road will require full-power from your chair, which Google says is anywhere between 400-800W.

In full, direct sunlight, using good-quality solar cells, that would require 2-4 square metres of solar cell, even more as soon as your chair turns the cells away.

But, don't be discouraged - you can always look at increasing the number of batteries you carry, and maybe having a solar charger running back in the car or at base-camp.

I never thought of that, but that would give me more miles. It gives me more information to go on so Thank You for your reply.
I won't give up until I have figured out a way to make this doable with sustainable power.

If you go with DU35mm's suggestion, you could run the generator on sustainable biofuels.

Heck, go the whole hog and convert a quad bike to run on old vegetable oil.

I did a mobility scooter conversion some years ago for a guy on a farm property.
He had similar problems like you have :)
Won't go into all mods and problems along the way, just the one for the power:
The guy only had solar power for his property and for the bad days a little generator so even charging a decent battery pack for a scooter was often a problem.
And since he needed the thing every day to check on his little farm animals and to get the rubbish bins down a 2.5km driveway every week...
After making the scooter offroad capable I added a small generator that runs on petrol.
Since it could serve a double pupose the only problem was to find one with a 24V outlet instead of the usual 12V.
"Silent" inverter type I might add.
The damn thing was close to $2000 but it offered a key start with build in battery, which was misused to fire it up through a switch on the handle bars.
A tank of fuel lasts for about 8 hours but the power output on the 24V side is only 5A, so not enough for full power runs on the scooter but more than enough to keep going on a low battery to get home.

Solar is only an option for a stationary charge point as even a 200W panel would already be bigger than a normal scooter....

Well Poot. Cell Phones have a Solar Panel that can charge on the move, so I thought this tech was already out and ready to go. Hmmmm... Gas is not an option for me even if I did have a "scooter" which I do not... at this point.

There has got to be an answer for out there somewhere and I will keep looking for it.

Thank You so much for replying, Blessings!
