Once the optimal site and type of tower has been chosen, construction of a foundation and installation of the tower can commence. Each tower has it's own foundation specification and each tower has it's own construction method; your installer can help you with this step. With the foundation built and the tower installed, the next step is to secure the turbine to the tower and connect the proper wiring. If you have chosen a grid-tie system your turbine will be wired to a controller and an inverter and then back into the grid. If you prefer or require a off-the-grid or micro-grid system, your installer will be helping you choose a system of battery storage.
