Solar power generation is the conversion of sunlight into electricity, either directly using photovoltaics (PV), or indirectly using concentrated solar power (CSP). Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. Photovoltaics convert light into an electric current using the photovoltaic effect. The International Energy Agency projected in 2014 that under its "high renewables" scenario, by 2050, solar photovoltaics and concentrated solar power would contribute about 16 and 11 percent, respectively, of the worldwide electricity consumption, and solar would be the world's largest source of electricity. Most solar installations would be in China and India. Photovoltaics were initially solely used as a source of electricity for small and medium-sized applications, from the calculator powered by a single solar cell to remote homes powered by an off-grid rooftop PV system. As the cost of solar electricity has fallen, the number of grid-connected solar PV systems has grown into the millions and utility-scale solar power stations with hundreds of megawatts are being built. Solar PV is rapidly becoming an inexpensive, low-carbon technology to harness renewable energy from the Sun.
Solar street lights are raised light sources which are powered by photovoltaic panels generally mounted on the lighting structure or integrated in the pole itself.
The photovoltaic panels charge a rechargeable battery, which powers a fluorescent or LED lamp during the night.

Solar Power systems are designed on the principle of daily energy balance-thus,
One must state the daily cumulative energy demand -over a 24 hour day AC or DC or
Mixed load’s (kilowatt/Watt hours/day: Load watts x hours/day the Load is required to be
ON) kwh/d loads the proposed system is expected to meet.

A solar lamp, is a light fixture composed of an LED lamp, solar panels, battery, charge controller and inverter. Depending on where and when the lamp is being used, it has various sizes of batteries.
The lamp operates no electricity or batteries are required due to the use of solar through the use of photovoltaic panel.
