Solar Powered Electric Wheelchair

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!

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!
