Solar PV Roof

We are planning a large warehouse for a juice factory, and wonder if the plant can supply itself with solar power instead of relying on the existing power grid.
The warehouse floor is 72m x 120m.
The size of the roof facing the sun is around 35m width x 120m length.
The same size faces the shade.
Can you send us a quote to cover the side which faces the sun and how much power will it generate please?
Best wishes
