Faced with ever-increasing energy demand, the earth's sources of non-renewable energy are not expected to last long. Among the many contenders vying to replace fossil fuels, photovoltaics (PV) offers many advantages, including needing little maintenance and being relatively "environmental-friendly". Owing to growing concerns regarding greenhouse gas emissions and energy security, Solar PV Systems energy is an attractive option. PV is emerging as a major power resource, steadily becoming more affordable and proving to be more reliable. This course covers the principles, design and installation of photovoltaic (PV) systems, and involves actual hands-on work with PV systems and equipment.
