The Interplay Between Heat Pumps and Solar Panels in Modern Homes

Imagine a home where your heating system and electricity combine to create an efficient, eco-friendly powerhouse. That’s the magic of combining heat pumps with solar panels. 

By harnessing the sun’s energy and using it to power your heat pump, you can enjoy a comfortable home while significantly reducing your energy bills and carbon footprint. 

In this guide, we’ll break down how heat pumps and solar panels work together, making it easy to understand and decide if this perfect pair is right for your home. 

Let’s dive into the world of smart, sustainable living!

How do heat pumps work?

Heat pumps aren’t new inventions, but technological advances mean they’re quieter, more efficient and versatile. There are three types of heat pumps available, with air-source pumps being the most accessible solution: 

  • Water-Source Heat Pumps: Households with access to a nearby lake, river, or pond can install water-source heat pumps. They collect heat and transfer it to your property. 
  • Ground-Source Heat Pumps: A ground-source heat pump uses a pipe system to collect and transfer heat from the earth’s natural temperatures. However, you’ll need a large garden to install them. Vertical systems can work in small spaces, but they’re more expensive. 
  • Air-Source Heat Pumps: These pumps are compatible with most properties, as they collect heat from the air. Most households choose an air-source heat pump due to minimal space and installation requirements. 

Heat pumps have the unique advantage of being able to both heat and cool properties. However, they run on electricity, which means there are some sustainability concerns—but the reduction in fossil fuels makes them a wise investment. 

How do solar panels work?

Solar panels leverage the sun’s energy and turn it into electricity. Their ability to generate clean energy means households everywhere can move towards energy independence and commit positively to the environment. 

Between January 2023 and 2024, solar panel installation increased by 6.6% across the UK (Energy Live News). The continued growth of solar energy means there’s every reason to expect significant installation increases between 2024 and 2030. 

Depending on your system, you can reduce your energy bills or move towards complete independence from the grid. 

Can households combine air pumps and solar panels?

Yes, they absolutely can. When you think about it, opting for a combination makes sense – because each complements the other perfectly. They can also cancel out each other’s negative points, lowering carbon emissions and saving energy bills. 

Let’s explore the benefits of installing both heat pumps and solar panels. 

Long term savings 

Both heat pumps and solar panels require an initial investment, but government grants can make them more affordable. 

Solar panels cost between £5,000 and £13,000 on average, depending on the system you choose, and an air-source heat pump costs from £2,000 to £20,000. Yes, they can be expensive, but it’s essential to remember the long-term savings. 

For example, if you’re using solar panels to generate clean energy, the heat pump can run off this energy, reducing your reliance on the electricity grid. These savings will also result in a faster ROI in the future. 

Energy efficiency 

According to Nesta, the average gas boiler emits 2.2 tonnes of CO2 annually, and home heating systems contribute to 38% of gas usage in the UK. 

Electricity also creates carbon emissions, with 2023 recording 162 grams of carbon dioxide each kilowatt hour (Carbon Brief). While 2023 reached the lowest levels since 1957, there’s still a long way to go. 

Combining heat pumps and solar panels offers significant environmental benefits. The electricity generated by the panels will power your heat pump, reducing your reliance on artificial heating and cooling. 

Things to consider before making a decision

When deciding whether to combine solar panels and heat pumps, the immediate costs and long-term implications must be considered. Jumping into the decision without proper research and planning could cost more money. 


The government offers a range of grants and incentives to encourage people to move away from fossil fuels. Households can use the Boiler Upgrade Scheme, which gives them up to £7,500 towards heat pump installation costs. 

Solar panels won’t stop you from getting the grant if you’re transitioning from an old or inefficient boiler. If you want to install solar panels, use the Smart Export Guarantee and 0% VAT initiatives. 

Low-income households might be eligible for the ECO4 Scheme, but local authorities are responsible for allocating these funds.


If you already have solar panels, it’s important to assess how much energy they generate compared with your property’s consumption rates. 

In some cases, upgrading your current solar panel system to a larger one might be best, ensuring they can power the heat pump and your appliances. 

While this might cost more initially, it’s beneficial in the long run, as you can reduce your energy bills and carbon emissions. 

Local restrictions 

Most properties can benefit from heat pump and solar panel installation under permitted development rules, so you won’t need to apply for planning permission. 

Listed buildings and properties in conservation areas might have stricter rules regarding the placement of renewable energy solutions.

However, Historic England recently announced that they’ll be relaxing the rules on heat pumps and solar panels for listed buildings, making them more accessible. 

What does the future hold for solar panels and heat pumps?

Nobody knows what the future holds, but all signs point to heat pump installations becoming commonplace in new-build homes. 

Right now, the UK trails behind other European countries, but initiatives and grants pave the way for households to benefit from renewable energy. 

We can also expect collaborations between solar panels and heat pumps, empowering people to take charge of their energy needs and achieve independence from the grid. 

With the many grants available, there’s never been a better time to invest in renewable energy solutions.
