Want to install a wind turbine?

If you are in the UK then take our Wind Site Self-Assessment - Step 1 of our modular Windpower Feasibility Study. It takes about 20 minutes to work through the basic checks to see if your site might be suitable, including:

  • Estimating wind speed
  • Checking proximity of nearby properties
  • Checking site access and approach roads
  • Investigating connection with the grid

If you are in the Republic of Ireland, or overseas, the first step is to consider our modular Windpower Feasibility Study, so please Contact us to discuss your site further.
