On-Grid System


What is On-Grid System ?

On-Grid or Grid-tie solar systems are the most common and widely used by homes and businesses. These systems do not need batteries and use Specially designed grid inverters and are connected to the public electricity grid. Any excess solar power that you generate is exported to the electricity grid and you usually gets credits for the energy you export.

Where On-Grid Systems are recommended ?

On-Grid systems are recommended for those areas where power cuts are very seldom throughout the year. Also it requires AC sensing to run the unit.

Can we get power during power cuts ?

No, On-Grid system needs AC sensing to run the system so when there is any power cut the system shuts down til the power rectifies because its has a safety feature.

Where these systems can be installed ?

In homes, Govt or Commercial buildings, Shops, Industry, Religious places, Schools, Colleges and any other building where Grid power is available

Can i run air conditioner and other high surge load ?

On-Grid systems are power producers and connected directly to the main junction box wiring so whatever load is running it doesn't matter as the system produces 4 - 6 units per KW depending upon the quality and efficiency of solar panels and grid inverters are used.

What are the benefits of On-Grid System

  1. System almost saves more than 80% in billing cycle.

  2. System has low cost as no batteries are used in this system.

  3. Exports excess power to the grid and excess units are added in next billing cycle.

  4. It has long life.

What are the limitation of On-Grid System

  1. Suitable for those areas where power cuts are seldom

  2. System runs during day time only

  3. System has no Batteries for storage

  4. System shuts down during power cuts for safety purpose & turns on again automatically when power is available

What is the maximum capacity in (KW) system is recommended for my building ?

On-Grid system are installed with 80% capacity of the consumer's total sanctioned load.

For Example : If the total sanctioned load of the consumer is 10 KW then 8 KW would be the maximum capacity consumer can install so consumer can install from minimum of 1kw -8KW as per roof top available.

How can i reduce maximum bill charges with perfect sizing ?

If you are living in the same building for at least 1 or 2 years then we can check the annual consumption in the electric bills in consumption history in KWh of the last 12 months or the data can be requested from your distributor.Now divide total annual consumption with 12 months and then again divide with 30 days. we will get per day average consumption.

For example : January 230 units , February 250 units, March 290 units, April 550 units, May 570 units, June 580 units, July 540 units, August 380 units, September 350 units, October 300 units, November 250 units, December 210 units.

Total annual consumption : 230 +250+290+550+570+580+540+380+350+300+250+210 = 4500 units

average per month units : 4500 /12= 375 units

average per day units : 375/30= 12.5 or 13 units per day average

Solar system produces 3.5 units/ KW | 4 units /KW | 5 units / KW | 6 units /KW (depending upon quality and efficiency of system)

In above example let us take 5 units/KW

System Capacity would be 13 units / 5 units = 2.6 KW so we can go for 3 KW solar on grid roof top

What is the total area required for system ?

It requires 110 Sq feet or 10 Sq meters of area per KW. It mean 1 KW system requires 110 Sq feet or 10 Sq meters of area.
