Solar power is the conversion of sunlight into electricity, either directly using  photovoltaics (PV), or indirectly using concentrated Solar system (CSP). Concentrated Solar power use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. Photovoltaics convert light into electric current using the Photovoltaic effect.
Solar power Benefits
- It is a renewable and natural resource.
- It is non-polluting. Unlike oil, it does not emit greenhouse gases or carcinogens into the air.
- Light and energy from the sun costs nothing. Once you purchase the equipment to collect and convert energy from the sun, it costs you nothing to run.
- Solar cells can last a lifetime.
- You’re not required to connect to the power grid. You can be completely self-sufficient and live off-the-grid.
- Solar cells require little maintenance.
- Most systems have a life span of 30 to 40 years.
- Most systems carry a full warranty for 20 to 30 years or more.
- Unlike traditional monstrous panel systems, many modern systems are sleeker such as Uni-Solar rolls that lay directly on the roof like regular roofing materials.
