News Desk. If you also want to run AC for 24 hours free, then you can use solar panel. But the question is how much kilowatt solar panel will be installed to run a 1.5 ton AC. Actually it is seen that people keeping in AC house are often troubled by their electricity bill. But if the solar panel is used then you will be very savable.

Let us tell you that 1.5 tonne inverter AC usually takes 1.4 kw per hour power. If it runs 24 hours, then 33.6 units of electricity are consumed. In such a situation, you need a solar system that generates about 34 units of electricity every day. 1KW solar panels in areas like Delhi generate about 5 units of electricity per day, so it will be right for 34 units to install 7.5 to 8kw on grid panels. To install solar systems of 8kw, you need 600 to 700 sq ft. It can also be applied on the roof.

Which solar system to choose and how much cost

Out of three types of solar systems, on-grid is the best and affordable in this case. The on grid is directly connected to the electricity meter, which costs 4 to 4.5 lakhs and on this, 20-40 percent subsidy is received from the government. The second is the hybrid system that comes with battery backup. Its cost is 5.5 to 6.5 lakh rupees. The third is the off-grid system, which is completely dependent on battery backup and is also not considered suitable for AC. It costs 6.5 to 7 lakh rupees.

Careful things

It is important to take care of some things before installing solar panels. First check the availability of sunlight in your area. Choose the solar panel of the CBIS certified brand. DICCOM approval is necessary for on-grid systems. Under the supervision of experts, get installation done.
