Are Solar Panels and Air Source Heat Pumps Better Together? 

If you’re thinking about using solar panels to power an air source heat pump at home, you’re on the right track to becoming an energy-efficient household, as well as cutting down your energy bill costs. But how many solar panels do you need to make it all work? In this article, we’ll simplify how these two technologies work together and figure out how many solar panels you’ll need to run your air source heat pump to its full potential.  

Understanding Solar Panels and Air Source Heat Pumps 

To undestand how they both work in tandem,  it must first but understood how solar panels and air source heat pumps solely work: 

Solar Panels 

Solar panels absorb energy from sunlight and generates it into electricity. It’s a clean and renewable energy source that can help power your home. Commonly, they are placed on your roof that will need to be south facing.  

Air Source Heat Pumps 

Air source heat pumps pull thermal energy (heat) that is available from the outside air, even when it’s cold, and use it to warm your home. Amazingly, they can operate in temperatures that drop down to –15* thanks to thermal energy always being present within the air. They will cut energy costs and make your property more energy efficient.  

How do Solar Panels and Heat Pumps Team Up? 

Heat pumps and solar panels are the perfect match, one can begin to see how they work together, benefit eachother, and create a carbon freidnly enviroment for your home.  

Here’s how they work hand in hand: 

1. Powering the Heat Pump:

When the sun is out in the daytime, your solar panels will generate electricity. This electricity can then be utilised  to run your heat pump. A drastic change in your energy bills will begin to unfold by using your own generated electricity to power the heat source for your home. This also creates a energy efficient home as you will not be burning any fossil fuel as you would with a traditional gas boiler.  

 2. Extra Electricity: 

If your solar panels generate more electricity than your heat pump requires, the extra power can go back into the grid. You might even benefit from this financially as you could receive credits or money for surplus electricity generated.  

Determine Your Solar Panel Needs 

To figure out how many solar panels you’ll need to run your air source heat pump, consider these factors: 

1. Heat Pump’s Electricity Use:

It will be useful to find out how much electricity your air source heat pump uses. You can usually find this info in the heat pump’s specifications and will be measured in kilowatts (kW) or watts (W). Knowing this will help you understand the energy that your solar panels will need to generate. 

2. Sunlight Where You Live:

You will need to think about how much sunlight your area gets in a year. Generally, your property will need to get sunlight between the hours of 10am and 4pm to generate enough for your home. Ultimately this will impact the amount of energy your solar panels will generate in the day. 

3. Efficiency:

Keep in mind that different solar panels and heat pumps have various efficiency ratings and will impact the amount of energy generated through solar and energy required for the heat pump. 

4. Your Energy Goal:

It can be helpful for you to know how much of your heat pump’s electricity you want to come from solar panels, this way you can determine what your ultimate energy goal is and how much you want to save in costs. You can also get an overview of how efficient your home will be.  

By taking all of these factors into consideration, you can work out the number of solar panels you’ll need to run your air source heat pump effectively. 

Get Professional Advice 

Figuring out your solar panel requirments on your own can be quite the task. You should always seek professional advice when it comes to determining what you need. A solar energy expert or a heating and cooling specialist can look at your specific circumstacnes, taking into account your heat pump’s efficiency, your location, and your energy goals 

Summary 

In summary, solar panels and air source heat pumps work together to give you an eco-friendly and budget-friendly way to heat your home. By understanding how these two technologies compliment each other, and if you receive expert advice, you can decide on the right number of solar panels to power your heat pump and reduce your energy bills and improve the energy efficiency of your home.
