Running an AC off-grid means cooling your home using an alternative energy source other than what your city or county provides. A good grid alternative involves harnessing the sun with a solar-powered AC or installing solar panels to power the entire home. Learn about the cost and benefits of solar panels in Arizona.
How Much It Costs To Run AC off Solar vs the Grid
The average cost of a solar-powered AC is about $5,000, including installation costs. When factoring in federal tax credits and other incentives, this may decrease closer to $3,700. Air conditioning is about 12% of the total household electricity cost. That means an average Arizona home with an annual electricity expense of $1,400 uses about $170 to run the AC on the grid.
Alternatively, you can install solar panels to run the AC and other electric appliances. The cost of solar panels in Arizona depends on size and quality, but the prices range between $6,621 and $22,068. Most homes in Arizona use 9 kW solar panels, which cost $19,862 before tax credits. When you include tax credits and incentives, a 9 kW solar can cost as low as $13,903.
Average Payback Period
Installing a solar-powered AC that costs $3,700 has a payback period of 21 years ($3,700/$170), assuming you save $170 annually. Powering an AC with solar panels, on the other hand, has a payback period of 10 years ($13,903/$1,400), assuming you save $,1400 on your annual electricity. Installing solar panels is cheaper since you start running the AC off-grid at almost zero cost.
Reasons To Use Solar Panels To Power Your AC
While the initial installation cost appears high, several factors make solar panels a better option to power your AC. Here are specific reasons to choose solar over grid electricity.
Cut Down On Energy Costs
Operating the AC on solar cuts down energy costs since you can enjoy electricity at almost zero cost after the payback period. You can also run your AC the whole day with no additional costs. Remember, powering the grid electricity increases your energy bill continuously until you turn it off.
Enhance Power Reliability
Going solar allows you to continue operating your air conditioning unit even when the neighborhood is experiencing an overload or blackout. That means you can enjoy cold air independent of the grid power fluctuations, especially if you install a backup battery.
Move Toward Environmental Sustainability
Solar is a renewable source of energy that minimizes reliance on fossil fuel, reducing your carbon footprint. Using solar to power the air conditioner keeps your home cool while reducing global warming and helping your community.
