Solar tech has moved on surfy.
New semi-flexible panels of a certain type do not require to be angled towards the sun.
One of the key elements is the right solar charge controller with the right panel, wiring and battery.
I'd suggest you don't get tempted by cheap kit as, in this instance, it really would be money wasted.
Best get real facts! Whatever you chose to do, have fun!

On sunny days this is enough for Fridge/Smartphone/Notebook - and costs under 100 Euro. EFTE brings a lot, if you panel is not directed to the sun. It powers the same power than my 120W non EFTE Panel - when both are not directed into the sun.

But also a good Solarpanel with EFTE will bring more juice - when directed to the sun.. Mabe you missèd it, because I was editing some changes.

Landrovers used to have an option called the Safari roof, a second layer above the actual roof with some ventilation so the bit in the sun had an insulative layer of air between it and the actual roof. Some German truck builders offer it too.
You could add such a second layer to help keep cool in the sun, and put flexy panels on that? They stay cooler so work better, interior stays cool, all good?
A solid solar panel would do the same thing but with gaps between. Even black mesh as a roof rack floor seems to reduce internal vehicle roof temps.
What's under the roof it's going on, bare metal or insulation?

Membership - help keep us going!
Horizons Unlimited is not a big multi-national company, just two people who love motorcycle travel and have grown what started as a hobby in 1997 into a full time job (usually 8-10 hours per day and 7 days a week) and a labour of love. To keep it going and a roof over our heads, we run events all over the world with the help of volunteers; we sell inspirational and informative DVDs; we have a few selected advertisers; and we make a small amount from memberships.
You don't have to be a Member to come to an HU meeting, access the website, or ask questions on the HUBB. What you get for your membership contribution is our sincere gratitude, good karma and knowing that you're helping to keep the motorcycle travel dream alive. Contributing Members and Gold Members do get additional features on the HUBB. Here's a list of all the Member benefits on the HUBB.
