This Solar Home in Nagpur Plans to ‘Sell’ Electricity to the Government Through Grid Tie Solar Installation

Why an On-Grid System Over an Off-Grid Solar System?

Mr. Suryakant lives in Nagpur city in the state of Maharashtra. About a year back, Suryakant had installed an inverter battery system in his home since the area that he lives in experiences frequent power cuts. But Suryakant and his family faced too many issues with their battery system. It wouldn’t provide enough back up and Suryakant spent tons of money in maintaining the inverter battery system.


Suryakant then read articles about on-grid solar system and he decided that it was perfect for his home.  PV on-grid rooftop solar power system is one of the most popularly used solar solutions for houses and commercial establishments. Grid-tie solar, also known as on-grid, works in connection with the main grid. It offers the advantage of running load directly through solar and selling excess solar power back to electricity company by feeding the grid.

Nagpur receives approximately 12 hours of day light every day. And investing in solar power in this area would definitely bring perfect results.

Suryakant then approached Milind and after a detailed discussion, Milind advised him to install Su-Kam’s grid-tie inverter in his home. Grid-tie inverter would not only reduce his monthly electricity bill by running his home load on solar but would also help him earn money by selling the excess solar power produced by solar panels back to the grid.

And so Suryakant installed the following system in his home.

Technical Specifications

  1. Su-Kam’s grid-tie inverter – 2KW
  2. Solar Panels 250W/24V – 8 panels


Why Grid-Tie Inverter?

Grid-tie inverters are an on-grid rooftop solar solution that can run the load completely on solar and also sell excess solar power back to the company by feeding the power to the grid. Su-kam’s grid-tie inverters are 97% efficient, which can help the user make use of maximum power coming from the sun.


Units Generated and Load Running

The system is expected to generate approximately 10 to 12 units of electricity on a daily basis depending on weather conditions. The installation was a success. The system is now running on solar and provides electricity in house (two floored) at all times. Their monthly electricity bill was approximately INR 3500 per month.

How Does Net Metering Work?

The concept of selling back solar energy to the electricity board is called ‘Net metering’. Let us understand this with an example. In this case, the solar panels will generate approximately 250 units of electricity per month. So, let’s take for example Mr. Suryakanth uses 100 units out of 250 units from solar power to run his load and exports the rest of 150 units to the electricity board. He also imports 50 units from the electricity board to run his load so he is essentially exporting a net total of 100 units if we subtract 50 units from it. These 100 units exported to the electricity board will get credited in his account.

In his next billing cycle, these 100 units will be deducted from the amount he owes to the electricity board. And so on and so forth. Whatever be the units he exports to the electricity board will be deducted from the units he imports. This is the net metering concept.

The Maharashtra (MEDA) government also gives subsidy on on-grid solar systems. So, in general on 1KW solar power plant, an amount of INR 21000 will be given as subsidy to the customer. If 2KW system is installed, then INR 42000 will be given and so on.

The net metering and subsidy given by the government makes solar power a very cost effective and affordable solution for one and all.

Mr. Milind says, ‘We have installed a 2KW grid tie inverter in Mr. Suryakanth’s home about 10 days back according to their load requirements. Their home has 2 Air conditioners, 3 fans and about 6 tubelights and a water heater. This solar system generates approximately 9 units per day since the installation. We are hopeful that their monthly electricity bill reduces down by 80% in their next cycle on 15th December.’

We wish Mr. Suryakanth and his family all the best and hope to serve him and his family again in the future.
