Great landing :)

Hi Omer. My set of 5 Powerfilm solar cells all together deliver about 2.5 W under perfect conditions. They are not particularly efficient on a W/m^2 basis - only about 7%. There are other cells with much higher W/m^2 metrics. …

Hi Jack. More technical details about the solar cells, etc are given in the rev 1 post (http://diydrones.com/profiles/blogs/diy-solar-airplane)

Nice work Louis. What is the efficiency of the cells and how many watts do they produce?

This is very cool. Can you post more information on where you purchased the solar panels and what model? What is the voltage output of each panel?

Is some progress? Sun is getting higher every day.
Louis LeGrand commented on Curt Olson's blog post 'Shadow Cam'
I am just brainstorming here, but imagine a sensor whose output was the direction of the sun.
Since you know the direction of the sun in the ECEF coordinates, you could partially determine your own attitude in ECEF coordinates. There would be an…
Louis LeGrand commented on Curt Olson's blog post 'Shadow Cam'
Nice work! The video provides definite proof that your attitude estimation is working very well.
It occurs to me that it should be possible to run a system the other way. That is, by tracking your shadow (or the sun) you can estimate your attitude…

I have been tinkering with solar powered RC planes this summer. The photos above shows the latest incarnation. This model uses the Parkzone Vapor's radio gear and motor ( http://www.parkzone.com/Products/Default.aspx?ProdID=PKZ3380 ), plus five Powerfilm…See More
