UK government body has closed an examination of the application for the project comprising up to 194 turbines capable of producing electricity for around 700,000 homes.
The examination that started six months ago saw impact on tourism as the main concern.
Bournemouth Borough Council is claiming 4,923 jobs would be lost while GBP 6.3 billion would be taken from the local economy over the life of the project.
Isle of Wight Council is the only local council backing the scheme that could create 1,700 local jobs during the four-year construction phase and 140 local permanent jobs annually for the 25-year operational life of the project.
The Inspectorate has until June to report to Secretary of State, who then has three months to give its verdict on the project.
