Can You Power An Air Source Heat Pump With Solar Panels?

As a company dedicated to providing efficient and sustainable heating solutions in Edinburgh, we at The Edinburgh Boiler Company are often asked about the possibility of powering an air-source heat pump with solar panels. In this blog post, we’ll explore this question in-depth and provide you with the information you need to make an informed decision about your home’s heating system in the Scottish capital.

Can You Power an Air Source Heat Pump with Solar Panels in Edinburgh?

The short answer is yes, you can power an air source heat pump with solar panels in Edinburgh. However, there are several factors to consider when combining these two technologies in the Scottish climate. Getting solar panels installed helps generate electricity, which can be used to run your heat pump, reducing your reliance on grid electricity and potentially lowering your energy bills.

To power your heat pump with solar energy in Edinburgh effectively, you’ll need a sufficiently sized solar panel system. The number of solar panels required will depend on your heat pump’s energy consumption and your home’s overall energy needs. A typical air source heat pump in an average Edinburgh home might require around 3,000 to 4,000 kWh of electricity per year. To generate this much energy, you would need a solar array of approximately 4 to 5 kW.

Advantages of Combining Solar Panels and Air Source Heat Pumps in Edinburgh

  1. Reduced Carbon Footprint: By using renewable energy from solar panels to power your heat pump, you can significantly reduce your Edinburgh home’s carbon footprint compared to using a traditional gas boiler.
  2. Lower Energy Bills: Generating your own electricity with solar panels can help reduce your reliance on grid electricity, potentially leading to lower energy bills in Edinburgh.
  3. Energy Efficiency: Air source heat pumps are highly energy-efficient, with some models achieving a Coefficient of Performance (COP) of 4 or higher, meaning they can generate 4 units of heat for every unit of electricity consumed.

Challenges of Powering an Air Source Heat Pump with Solar Panels in Edinburgh

  1. Roof Space: To generate enough energy to power both your heat pump and your Edinburgh home’s other electrical needs, you’ll require a larger solar panel system, which means you’ll need sufficient roof space to accommodate the solar array.
  2. Upfront Solar Panel and Heat Pump Cost: Installing both solar panels and an air source heat pump can involve significant upfront costs in Edinburgh, although long-term savings on energy bills and potential government incentives can help offset this.
  3. Seasonal Variations: Solar panels generate less electricity during the winter months when days are shorter, and heat pumps typically require more energy to maintain a comfortable temperature. This is particularly relevant in Edinburgh, where winters can be cold and dark. This means you may need to rely more on grid electricity during colder periods.

Sizing Your Solar Panel System for an Air Source Heat Pump in Edinburgh

To determine how many solar panels you need to power your heat pump in Edinburgh, you’ll need to consider several factors:

  1. Heat Pump Size: A larger heat pump will require more energy to run, so you’ll need a larger solar panel system to meet its needs.
  2. Home Size: Larger Edinburgh homes generally have higher energy consumption, which means you’ll need a larger solar array to cover both your heat pump and your home’s other electrical needs.
  3. Location: Edinburgh receives less sunlight than some other parts of the UK, which can impact the efficiency of your solar panels and the size of the system you’ll need.

As a general rule, you’ll need around 1 kW of solar panels for every 1,000 kWh of annual electricity consumption. So, if your heat pump requires 4,000 kWh per year and your Edinburgh home consumes an additional 4,000 kWh, you’ll need an 8 kW solar panel system to cover your total energy needs.

Solar Batteries and Excess Energy in Edinburgh

One way to optimise your solar panel system and ensure you have enough energy to power your heat pump in Edinburgh is by installing a solar battery. A solar battery allows you to store excess energy generated by your solar panels during the day, which can then be used to power your heat pump and other appliances during the night or on cloudy days when solar output is reduced.

If your solar panels generate more energy than your Edinburgh home consumes, you may also have the option to sell this excess energy back to the grid through a feed-in tariff or net metering scheme, depending on your energy company.

Heat Pump Costs and Savings in Edinburgh

The cost of an air source heat pump in Edinburgh can vary depending on factors such as the size of your home, the heat pump’s capacity, and installation complexity. On average, an air source heat pump costs between £12,000 and £15,000.

While the upfront cost may be higher than a traditional gas boiler, heat pumps can offer significant long-term savings on energy bills for Edinburgh homeowners. By combining your heat pump with solar panels, you can further reduce your reliance on grid electricity and potentially save even more on your energy costs.

According to the Energy Saving Trust, an average Edinburgh home switching from a gas boiler to an air source heat pump could save around £870 per year on fuel bills, based on current gas and electricity prices. When you factor in savings from generating your own solar power, these annual savings could be even greater.
