How solar Generated Electricity Works

workflow optimization made easy

On-grid system means connecting your solar system to your local power system and doesn’t require a backup battery, while off-grid system means not connecting your solar system to your local power system and requires a backup battery.

Photovoltaic system (Solar Power system)

A photovoltaic system also known as solar power system is a power system designed to supply usable power by means of photo -voltaic. PV systems convert light directly into electricity. It consists of an arrangement of several components, including solar panels to absorb and convert sunlight into electricity, a solar inverter to change the electric current from DC to AC, as well as mounting, cabling, and other electrical accessories to set up a working system.

PV systems range from small, rooftop-mounted or building-integrated systems with capacities from a few to several tens of kilowatts, to large utility-scale power stations of hundreds of megawatts. PV systems are either grid-connected or off-grid (stand-alone systems).

Types of solar panels

  1. Monocrystalline solar panels – have solar cells
    made from single crystal of silicon. Monocrystalline have high energy
    efficiency compared to polycrystalline.
  2. Polycrystalline solar panels- have solar cells
    made of many silicon fragments melted together.
  3. Thin-film:Also called (Amorphous silicon solar
    panels). These are solar panels made up of multiple thin light absorbing layers
    of photovoltaic materials that a laid to a substrate.


Advantages of solar pv

  • Solar PV is a renewable energy source- solar panels rely on sunlight which is available almost daily in a year.
  • Solar PV reduces electricity bills- solar light being a free energy reduces the amount of money paid for electricity bills.
  • Diverse application-solar PV can be used for multiple purposes.
  • Low maintenance cost-solar PV only need to be cleaned on the outside to get rid of stains and dust.
  • Solar PV reduces usage of fossil fuels
  • Solar PV operate silently
  • Solar PV are environmentally friendly and does not emit dangerous gases

Applications of solar pv

  • Solar pv can be used to generate heat and make hot water
  • Solar pv can be used to generate electricity
  • Solar cloth dryer use sun rays for drying clothes
  • Solar cookers use solar pv for cooking
  • Solar Water pumps use solar pv to pump water for farmers
  • Solar lights use solar panels to provide street lighting
  • Charging vehicle batteries
  • Solar powered fridges
  • Solar can also be applied in such as solar flashlights, solar fans, solar tablets, solar calculators, solar radios, solar watches etc.
