Illustrate how solar panels generate energy

Hello everybody, we need an illustration that shows how solar panels generate energy for a small business. But instead of a typical European house we would like to use one with a flat roof (as common in Mexico). Also a simple illustration with less colors and a more formal design would be good. For a general idea on what we are looking for I added some example images. The actual process that needs to be displayed in the illustration is the following: Sunlight hits the solar panels on the roof - electricity goes through two cables to the inverter - electricity goes from the inverter over two cables to the small business building - two cables go from the business building to the bidirectional meter - from the bidirectional meter one cable goes to an electrical grid. Overall the illustration will just be an image and does not include any words. Thanks a lot!
