If your monthly electricity bill is ₹3,000, what size solar system should you install? Here’s the breakdown.

If your household electricity bill is around ₹3,000, installing solar panels at home can help you save on that entire cost. Find out how much the installation costs and what subsidies are available.

Everyone is concerned about rising electricity bills. Bills tend to spike, especially during summer and winter, due to the increased use of electrical appliances. However, an alternative option has recently entered the market to provide relief from high electricity bills. Many people are now meeting their electricity needs by installing solar panels in their homes.

If your electricity bill is around ₹3,000, installing solar panels can bring that bill down to zero. Installing solar power not only eliminates the electricity bill but also allows you to avail of government subsidies. Let us explain what capacity solar system (in kilowatts) you should install for a ₹3,000 bill and what the associated costs would be.

Determining the required solar capacity based on your bill

The easiest way to determine the right solar panel setup for a home is to look at the electricity bill. If your average monthly bill is ₹3,000, it means you are consuming approximately 300 to 350 units of electricity per month. To fully cover this level of consumption, installing a 3kW (kilowatt) capacity solar system would be ideal.

A 3kW solar setup easily generates an average of 300 to 350 units of electricity per month, effectively meeting your power needs. Furthermore, if you decide to add new electronic appliances or an air conditioner (AC) in the future, this 3kW system can easily handle the additional load.

How many solar panels will be required?

When considering the installation of a 3-kilowatt solar system, the primary questions are how much rooftop space is required and how many panels are needed. High-efficiency solar panels ranging from 350 to 400 watts are readily available in the market today; based on this, you would need to install a total of 8 to 9 panels for a 3-kilowatt system.

How much space is required?

To install these panels, you need an open, sunny area on your roof—approximately 200 to 250 square feet—that receives direct sunlight throughout the day. If the roof is shaded by trees or nearby buildings, the panels' power generation could be reduced; therefore, having an open space is crucial. When installed at the correct angle, these panels will continuously generate free electricity for years without any issues.

Total cost and government subsidy

People are often initially daunted by the cost of installing solar panels, but available subsidies significantly reduce the expense. The total cost of installing a 3-kilowatt on-grid solar system ranges from approximately ₹1.5 lakh to ₹1.75 lakh. However, under the *Pradhan Mantri Surya Ghar Muft Bijli Yojana*, the government provides a direct subsidy of up to ₹78,000.

This cuts your financial burden in half. After the subsidy, your net cost becomes negligible, and the ₹3,000 saved on your monthly electricity bill allows you to recover the entire investment in just 2 to 2.5 years. For all the years that follow, you receive electricity completely free of charge.
