The technology of obtaining energy from the light of the sun is called Solar power system. Solar cells take the energy from sunlight and convert it to energy.This is done with semi-conducting materials like These solar cells cannot produce usable energy by themselves, so they have to be connected to other systems to carry the electricity generated.
Photovoltaic (PV) systems are grid-tied or off-grid systems.
The difference is that a grid-tied system can feed energy back into the power grid, utilizing the grid for storage. The off-grid system’s energy must be used as it is produced or stored via on-site battery.
When the sun is shining, the photovoltaic panels generate direct current (DC) electricity, which is converted to alternating current (AC) electricity by an inverter. With grid-tied systems, when the sun is not out, your electrical demand will be automatically provided by the utility.

Off-grid systems depend on energy stored on on-site batteries to deliver power when the system is not producing enough power.
The solar electric systems work on photovoltaic principle. The heart of the system is the solar cell. The single crystal silicon solar cells convert solar energy directly to electricity.

This electricity then charges the battery through a battery charger. The electrical energy thus stored in the battery is then utilized through inverter (DC to AC) or converter (DC to DC) for various purposes such as lighting, pumping and running of the TV.
A solar lantern works on photovoltaic energy. It consists of photovoltaic module, CFL tube (Compact Flurescent Light), inverter, electronics, battery and protection system. It is available in 6 W / 7 W capacity.

The light output from a 5 W / 7 W solar lantern is around 230 / 370 lumens which is equivalent to five times that of the conventional light.
A solar domestic light can be used for the lighting requirements in houses.
A solar domestic light can be used for the lighting requirements in houses.
It consists of photovoltaic module (18 W / 37 W / 74 W), CFL of 9/11 Watts, inverter, electronics, battery, protection system etc. Depending upon different configurations, the domestic light can be used for three to four hours. It can run the D.C. fan too.
The lightoutput from 9/11 Watt CFL is around 600/900 lumens respectively which is equivalent to five times the output from the conventional light.
The solar streetlights are suitable in remote areas, fields and other applications where light is required throughout the night.
The solar streetlights are suitable in remote areas, fields and other applications where light is required throughout the night.
It consists of photovoltaic module (37/74 Watts), CFL (11 Watts), battery, inverter, electronics, controls, poles and other hardware. Due to control electronics, the streetlight gets automatically switched ON at dusk, operates throughout the night and automatically gets switched OFF at dawn.
