Study Notes
- A photovoltaic (PV) system generates solar power using solar panels and an inverter.
- It includes mounting, cabling, and other electrical accessories to set up a working system.
- PV systems convert light directly into electricity.
- They are not the same as concentrated solar power or solar thermal systems.
- PV systems range from small rooftop systems to large utility-scale power stations.
- Most PV systems are grid-connected.
- They operate silently and without any moving parts or environmental emissions.
- A rooftop system recoups its energy investment within 0.7 to 2 years.
- A rooftop system produces about 95% of net clean renewable energy over a 30-year service lifetime.
- PV systems are a mature technology used for mainstream electricity generation.
