Illustrator Required for sketch image example

I have a client who is looking to produce an illustration for a powerpoint project. The topic is solar projects (ie solar panels/energy etc).

This part of the project is for a very rough pencil sketch as the brief is likely to change, but I need something initially to work from.

I will attach a small image I have put together to try to demonstrate what I am after but it is hard to explain!

I need this by early tomorrow morning (GMT time).

Thanks
