Wind turbine with particular combined radius specific solidities along the rotor radius

A horizontal axis wind turbine comprising a rotor having a plurality of blades, the rotor having a radius of at least 80 meters, the blades comprising:

• a root end and a tip end;
• a leading edge and a trailing edge;
• a shoulder between the root end and the tip end where a chord length defined between the leading edge and the trailing edge is at a maximum;
• wherein:
• Solr is at least 0.0146 at 0.7R;
• Solr is at least 0.0123 at 0.8R;
• Solr is at least 0.0099 at 0.9R;
• Solr is below 0.0164 at 0.7R;
• Solr is below 0.0133 at 0.8R;
• Solr is below 0.0108 at 0.9R;
• Solr being a combined radius specific solidity of the blades and is defined by:
