Hi,
i'm totally new in the EV world and I just know a little about electric, learned in the physics lessons. Elementary stuff like watt=ampère*volt,... but that's it!
I was dreaming already a long time about a permanent camper, and permanent in the meaning of 'my only house to live in the whole time'. I also have an other passion, and that are old brittish dubble decker busses. Add the one to the other and you have: a dubbel decker camper conversion.
Also, i'm quite engaged about the nature. I once red an article about the new tesla roadster, and i thought 'why don't make an electric camper'.
This is the idea: Because an original bus is way to expencive (over 35000 eurofor an old wreck), i had the idea to totally strip an old normal bus (one deck). Only the chassis and the skeleton will remain. Then, I ad an adittional second floor. Then I fit in an engine and the rest of the mechanics.
After this, I plate the outside (in that way it looks like and old bus, but in fact it's a fake one), and i make a nice camper-interiour. Living and storage on th first floor, bedroom, bathroom and studio (i'm a musician) on the second one.
Ok, enough about this. This forum is about electric vehicles, so let's talk about the electric side of this project.
Caused of my environemental engagement, i'm really allergic by the word CO2. I would love to make it totally indipendant of any sort of fuel. This by using only the power of solar panels on the top of the roof (about 18 m²) and eventuelly an aditional wind mill when i'm not riding.
This is what i want (at least)
- About 50 km travel distance each day
- Speed around 50-70 km/h
- Possibility to save power for 2-3 days
- Enough extra power for the rest of the devices in the camper (lights, heating and cooling, water,...)
A looked a bit on the forum and saw that their are 2 important things that influence the energy consumption.
1) The weight of the vehicle
=> Trying to save as lot weight as possible (making the vehicle itself light, not taking to much wich you,... staying slim :))
2) The frontal surface of the vehicle
=> big problem: an dubbledecker is about 4 meter high and 2.3 m width. This is 9.2 m².
On another forum, they helped my with the hight of the camper. Because with an hight of 4m, you can't pass under a lot of bridges, they made some kind of electric lift to lift up the upper section about 0.5m. So when i drive the camper, the hight is about 3.5 m. Still 8.02m².
Is it possible or not to make this work totally on solar energy???

For solar power it's important to knwo where you live and want to go.

You can use this utility to get an impression of how much energy you can collect each day with the 18m2. But you could increase that -if money is no objection- with a extendable and tiltable solar sunroof.

How much power your bus wil use for normal driving, I have no idea. I guess a lot. Or more.

...there's no way you'll do 50 on just solar panels...
Not directly without a large battery pack, no.

But on a sunny summer day you could collect something like 45kWh with 18m2 in southern Spain. In England 30kWh will be a top day.

That is enough to drive a normal car a 100 miles or more. But this is not a normal car.

Now there is an interesting thought. Have a microcar that fits in the motorhome, and charge it for running around. I don't know if you have them in Europe, but in the U.S. we have "Toy Haulers" that have a little garage in them for hauling motorcycles or small four wheelers -- that would be a good starting point.
