Can we run AC on solar electricity ?

Today, air conditioners are one of the most widely used electric equipment. With the worsening of weather, an increasing number of individuals are having air conditioners installed in their homes,workplaces, stores, schools, and other organisations. AC, on the other hand, is a high-power-consuming device, resulting in increased power consumption. As a result, the convenience of using air conditioners becomes rather unpleasant when the power bill arrives.

Solar panels are progressively becoming common in many parts of the world where they were not previously considered a viable alternative. Still, there are reservations about solar power’s effectiveness and ability to satisfy the power demands of high-power equipment such as air conditioners and refrigerators. In this post, we’ll answer those issues head-on and show you how to use your solar panel system to power air conditioners and other high-power equipment without breaking the bank.

What’s intriguing is that individuals are searching for ways to cut power use and costs while still using air conditioners. Installing solar systems and using solar energy to operate ACs is one of the most effective ways to fulfil both aims at the same time.

People are becoming more motivated to have solar panels installed by solar energy companies as electricity tariffs rise, power difficulties worsen, and solar panel costs fall. Solar panels placed by reputable solar manufacturers not only endure a long time, but also aid in the resolution of power issues.

The key point here is whether we can utilise solar energy to operate AC, despite the fact that we can run many home appliances with solar energy.

The answer is a resounding YES.
We can operate the air conditioner on solar electricity. Let’s have a look at the procedure. Solar panel systems are often divided into two categories: off-grid and on-grid.

Types of system for solar electricity

Using solar energy without relying on the grid is referred to as an off- grid solar system ,Solar panels, inverters, and batteries are all part of this system.
On the other hand, an on-grid solar system uses the grid to generate electricity to power appliances using solar panels and an inverter. Any of the two systems can be used to run air conditioners.

Using an On-grid solar system to power ACs, where these grid tie inverters manage heavy loads with the help of utility power supply, but an Off-grid solar system, with the assistance of a solar battery, can run ACs even without electricity.

By using an on grid system net metering can be used (especially important in winter months) .This will help in minimising your electricity bill. There are some other benefits such as no need for batteries & energy storage, less initial investment, more space saving. These facts demonstrate that there are many ways to save money.

Most Commonly Asked Questions

How many solar panels will be required to power a 1.5 tonne air conditioner?

The number of solar panels required to run a 1.5 tonne air conditioner comfortably is determined by the maximum power rating of the AC.However, as a general rule of thumb, we recommend getting approximately 1.5 times the solar panels installed power capacity. Eg. For a AC with 1.5 KW as highest rated power capacity, you should
install a rooftop solar power system of 1.5*1.5 = 2.25 KWp It is preferable to install 2kw minimum for a AC of 1 tonne rating.

Here is a calculated load consumption from major Air conditioners ( AC ), analysed by Bureau of Energy Efficiency.

What solar-powered appliances are available?

Solar panels transform light energy from the sun into electric energy that may be utilised by a variety of common products. The converted energy is then stored in batteries and utilised by various appliances according to their needs. It’s safe to assume that you can use solar energy to power nearly any electrical device that normally operates on regular electricity. Lights, fans, TVs, laptops, PlayStations, and other electronic devices are amongst them.

Some people tend to believe that utilising a solar power system to operate air conditioners and refrigerators is not a good idea, however this is a false claim that has been debunked several times.

How many batteries are required to run an air conditioner?

Batteries are devices that store converted solar energy so that it may be used by various household gadgets to perform daily tasks. Off-grid solar panel systems almost always require batteries to store the energy, which may then be utilised when there is no electricity available.
If you’re running a 1 tonne AC, most people advocate a four-battery configuration using 150 Ah cells (2-3 hr). As the AC capacity grows to 1.5 or 2-tons, this may alter.

Can I use solar to power a 1.5 tonne air conditioner without batteries?

This is a common query from people who want to install an on-grid solar panel system at their home, without investing huge amount of money in Battery storage.We propose that you calculate the power of your solar panel and the entire amount of power used by your air conditioner.In principle, you can operate a 1.5-ton air conditioner on solar without batteries if the solar panel generates enough electricity to drive the appliance.

It is crucial to note that a 1.5 tonne air conditioner (a.c.)uses around 1.6 kW of power. If you want to run a 1.5 tonne AC without batteries using solar power, we propose a 2.5- or 3-kW power system.

Overall, a greater kW capacity is preferable because you will be operating other appliances in addition to your air conditioner, which will consume more energy and put more strain on your solar panels.

In summary, you can operate a 1.5 tonne air conditioner without a battery, but you must first conduct thorough study on your power requirements and if your solar panels are capable of supplying them.

Money saving matters

For homes, offices, we recommend to install rooftop Solar power plant and Run your ACs completely on Solar energy for the daytime use and Rely on the utility power supply for running it at night time use, with credit units earned by exporting surplus power in daytime. Money saving is also a way of money earning.

So, Always install 2x the air conditioner load or maybe even more for completely offsetting the energy consumption by Solar power plant for day and night time use of Air conditioners.

And the best part of this is, you don’t have to invest in buying,operating and maintaining the Battery banks.

FREE AC = Faster ROI = Faster Adoption = hassle free and carbon neutral.

So Opt for a Rooftop solar power Plant ASAP And put you feet up and power on that AC, guilt free and without the worry of Electricity bills ever again.
