Rooftop solar energy

Rooftop Solar Technology

When the rays of the sun fall on solar modules placed on the rooftop of houses, commercial buildings or industries, the individual cells inside the module help convert sunlight into DC electricity. However, most appliances in our homework on AC electricity, and therefore the modules are connected to an inverter that does this conversion. Once the conversion has happened, the output of the inverter which is AC electricity, is connected to the mains of your home to allow you to use solar energy.

It is important to note that you can use electricity from your rooftop solar power plant in conjunction with the electricity sourced from your DISCOM. This kind of arrangement is very common and one that solar installers are experts at managing. However, if you want to go with a system that is backed by a battery to help you use solar at night time, you must go for a hybrid or an off-grid system.

Places having delays in net metering or no net metering facility can easily opt for a zero export device (Z.E.D) and start saving on their electricity bills from day 1 itself.

"How Solar Energy Works"?

  • Sunlight fallen on the Solar Panels Activate them to produce electricity
  • Sunlight fallen on the Solar Panels Activate them to produce electricity
  • DC (Direct Current) generated through the solar panels travels through the DC cable till the solar inverter.
  • Solar Inverter acts as the brain of the solar system which later on converts the DC (Direct Current) to AC (Alternating Current) which is further used by the appliances at our premises.
  • The Junction box in the solar system Installation acts as the protection device for the solar system installed so that it doesn't face any disruption.
  • All the heavy load i.e. ACs, Machinery, Geysers etc. and light load i.e. fan, television, fridge, light etc. can run on clean solar energy which is free.
  • Whichever unit generated by solar system isn't used by you in the same month goes back to the electricity grid and can be used by you the next month to reduce electricity bill and be energy independent.

Different types of Solar Plants:

Rooftop solar energy

ON Grid Solar Plant

It is a grid-connected solar power plant that uses the electricity grid as a primary source and needs no battery backup for storing excess energy. It is comparatively a more cost-effective form of the solar power plant.

Rooftop solar energy

Hybrid Solar Plant

It is a solar plant which has the capability to store excess electricity inside the batteries. The inverters used in these systems differ also they have batteries in extra which can provide backup for somewhere between 8 to 10 hours. Also, it is comparatively expensive than ON Grid Solar Plant.

Rooftop solar energy

OFF Grid Solar Plant

They are somewhat similar to Hybrid Solar Plant but the main difference is they are installed in places with no Grid support and are known as stand-alone system with extra batteries and a longer back up time period.
