In remote or isolated locations, hybrid renewable energy systems offer an effective option for meeting energy goals. With the plummeting costs of solar PV and its ease of installation, is there still a role for wind turbines in the design of a hybrid system? Our answer is yes; however, there are a number of factors to consider when choosing the best configuration for your location and needs.
