New Delhi: It is difficult to live without AC in the scorching heat of the capital, but when the electricity bill comes at the end of the month, the sweat starts to flow more. In such a situation, if you also feel that why not run solar system and run for free, then this news is for you. Here in easy language we are telling how many big solar panels are needed to run 1.5 tons AC 24 hours, how much will it cost and what is important to take care of.

How much electricity consumes 1.5 tons of AC daily?

Today’s inverter AC consumes about 1.4 units of electricity every hour. If it is run 24 hours throughout the day, it spends about 33.6 units of electricity. In such a situation, if you want to pick up the entire load solar panel, then you have to produce at least 34 units of electricity daily.

How many kilowott solar systems are required?

There is good sunlight in areas like Delhi and according to experts, 1KW solar system produces about 5 units of electricity daily. On this basis, for 34 units, you need a solar system of about 7kw to 8kw.

How much space will be needed?

To install the 8KW system, an open roof of at least 600 to 700 square feet is required, where sunlight is straight throughout the day. Lack of shade or sunlight can reduce power generation.

Which solar system to choose?

  • On-grid system: Best for areas like ₹ 4 to ₹ 4.5 lakhs, areas like Delhi.
  • Hybrid System: ₹ 5.5 to ₹ 6.5 lakh, right for areas with power cuts.
  • Off-grind systems: ₹ 6.5 to ₹ 7 lakh, useful but expensive in not electricity.

Subsidy and expenses

Under the government’s “PM Surya Ghar Yojana”, 20-30% subsidy is available, which can cost the cost of 8kw on-grid system from ₹ 3 to ₹ 3.6 lakh.

Keep these things in mind in installation

  • Get the system installed by certified installer
  • Take IS mark panels and inverter
  • Get south facing installation
  • Clean the panel from time to time
  • Do not forget to register for net metering

Note
