You will get relief from electricity bill in summer! Know how many kilowatts of solar panels will be required for 1.5 ton AC.

Nowadays, with increasing heat, air conditioner (AC) has become an essential facility in homes, but running AC increases the electricity consumption significantly. In such a situation, the electricity bill also starts increasing rapidly every month. For this reason, many people are now looking for the solution in solar energy. Solar panels convert sunlight into electricity and, once installed, provide long-term benefits of low-cost or almost free electricity. This not only reduces the electricity bill but also has a positive impact on the environment.

However, while installing a solar system, it is very important to choose the right size and capacity. If the system is small or of wrong capacity, then the AC and other heavy electrical appliances in the house will not be able to operate properly. Therefore, it is wise to install solar panels only after assessing the load as per the need, so that electricity can be used comfortably without any interruption in summer.

What is the power consumption of 1.5 ton AC?

In India, most people install 1.5 ton inverter AC. This AC consumes an average of 1.2 to 1.8 kilowatts of electricity while running. 5 star inverter AC draws less power, whereas older models draw more power. If the AC is run for 8 hours, 8 to 14 units of electricity can be used daily. If fans, lights and other household items are also added to this, the consumption increases further.

How much solar system should be installed for 1.5 ton AC?

A solar system of at least 2 to 2.5 kW may be sufficient to run just the AC, but a 3 to 5 kW system is considered better for running the entire house and for comfortable use. With this, the AC runs well during the day and other items like fridge, fan, TV and lights also run easily. The efficiency of solar panels depends on sunlight. On an average, India gets 4 to 5 hours of good sunshine. The 3 kW system can generate 12 to 15 units of electricity daily, which is enough for 1.5 ton AC and other equipment. If you install a battery, you can run the AC even in the evening and night, but this increases the expense.

Advice on choosing the right solar system

While installing solar panels, keep in mind the total electricity requirement of the house. Do not install a small system just by looking at the AC, otherwise it may cause problems later. Choose good quality 400 to 550 Watt panels. About 6 to 8 panels can be installed in a 3 kW system. Along with this, solar inverter is also necessary. Hybrid inverter is better because it works from both grid and solar. Install panels on the roof where there is maximum sunlight. Planting in shade or at the wrong place reduces returns.

By installing solar system, you can save up to 70-90% in electricity bill. Initial expenditure is high, but the money is recovered in 4-5 years. Government subsidy can also be available. However, solar panels do not generate electricity at night, so batteries may be necessary for heavy use. Production reduces when the weather is bad. Therefore, get the work done by a good brand and certified installer. To run 1.5 ton AC comfortably, a solar system of 3 kW or above is best. This will not only run the AC but the entire house can also run on solar. By choosing the right planning and size, you can get both coolness in summer and saving on bills.
