The land, belonging to Carr Hall Home and Garden Centre, is in Wilpshire, Lancashire.
Some local residents have complained about the plan for the Ribble Valley site.
The turbines would be installed by renewable energy experts DC21.
GC21 told planners:
"The turbines should integrate well into the landscape, impact on residential amenity and landscape character will be minimal and crucially the project will not present any significant risks to biodiversity or sensitive ecological features either on site or within the surrounding area.
"Carr Hall Home and Garden Centre will benefit from free, low carbon electricity with the balance of generated power being exported and used in the local district network. Furthermore, the CO2 savings associated with the proposal will make a significant contribution to climate change mitigation. In conclusion, the benefits associated with this project outweigh any impact."
