DC Power Supply 5VDC @ 1A from solar panel array

Hi,
We got a requst to design a DC Power Supply which will be sourced from solar panel array connected in series. At peak the DC volt is rated to 1200VDC, typically 800VDC.

Honestly this is a bit above my capabilities, nevertheless I took the challenge as part of learning curve. I am studying about solar array output, and it does not look like a dc power source.

I'm also need to address the method of reducing the 1200VDC to 5V, definitely need to use switching regulator. Component selection for high voltage will be a issue too.

Guys, I am willing yo burn candle and time to experiments to develop reliable solution.

Really appreciate if you guys can point me in the right direction or give me some advice or reference design.

Looking for in hearing from you.
