Key Takeaways

• Solar panels in the UK have exceeded 4GW capacity, with half a million households using them for electricity generation.
• Combining solar panels with air or ground source heat pumps can significantly reduce electricity bills and environmental impact.
• The number of solar panels needed depends on various factors, including roof space and heating requirements, and this combination can provide efficient and eco-friendly heating.

What Is an Air Source Heat Pump?

An air-source heat pump is a unique system that uses natural air to heat your space. In essence, it has reversible anatomy that the heat source during the heating more.

Similarly, you can use air-source heat pumps with a cooling mode. It has a heat exchanger in its external body, as used by air conditioners.

Fun Fact: It has somewhat similar functionality to a boiler.

The Benefits of Using an Air Source Heat Pump

Air source heat pumps have essential advantages that you need to look into:

• Low carbon footprint during energy consumption
• Easy installation and low maintenance
• Saves energy bills
• Used for hot water generation and home heating

If you combine solar panels with air-source heat pumps, you can skyrocket the advantages. Gone are the days of using fossil fuels to power your home, and you will not incur heating costs.

The heat produced will be purely from the solar cells. The benefits of this combination are:

• It saves your electricity bill significantly greater
• You will achieve efficiency rates by using less electricity from fuels
• It protects you from rising electricity costs in the near future
• You get incentives for using a combined system with renewable energy

The eco-friendliness of an air source heat pump is exponential when combined with solar panels.

What is a Ground Source Heat Pump?

Unlike an air-source heat pump, a ground-source heat pump is infinitely more effective. It can save energy as this heating and cooling system integrates with the buildings. This heat pump offers the maximum output because it sources the heat from the ground and transfers it to the building. It takes advantage of the energy-relative constancy found in the ground temperatures in the UK.

For example, this heat pump has a mechanical anatomy that circulates the thermal energy through a liquid solution. This solution travels through the ground loops and heats your home or generates hot water.

Fun Fact: This heat pump is called a geothermal pump in many parts of the world.

The Benefits of Using a Ground Source Heat Pump

Most of the benefits of a ground-source heat pump are similar to an air-source heat pump. The heating system alone will give you summer and winter advantages in your house like:

• It consumes 25% less energy than a conventional heat pump
• It is an efficient way to heat or cool your home in the UK
• It is low maintenance and has a heating capacity like no other
• It decreases fuel emissions, making it safer for the environment

Now, if you integrate a solar panel array with these heat pumps, you will harness the power of the sun and the planet. This heating system combined will help regulate your house temperature throughout the seasons. It will use sunlight from the solar panels’ power to control the temperature.

This combined system will reduce the electricity input bills while providing hot water and a hot air source under your roof.

Integrating Solar Panels and Heat Pumps

You can use solar panels as an air source heat pump and a geothermal pump. Your heating problems and electricity bills will be a thing of the past once you install such a system.

It will ensure that your heating and hot water requirements are met in an environmentally friendly manner. Ideally, solar panels can produce electricity from the sun to power the hot pump system under your roof. Yet, the amount of energy you generate will depend on the sun and the size of your solar array.

If you use solar thermal panels, it will effortlessly warm your water and reduce electrical power consumption. In contrast, if you install a PV system, you can convert solar energy to electricity. Combining these will help you harness the sunlight and power the pumps without burning harmful fuels.

Will it Work?

In the UK, the average system will be 4kW, the maximum electricity output produced on a sunny day. It can differ depending on the weather conditions and make more during the afternoon. 4kW = 3,400 kWh/Year, taking 26m² of your roof space.

On average, your home will use 3,700kWh every year. It means that a 4kW solar panel will provide you with enough electricity, but you will need to borrow 300kWh from the grid.

Most of the old UK homes will utilise a boiler. Hence, gas consumption might be higher, whereas electricity usage will be lower. If you install cost-effective heat pumps, the electricity usage will be higher.

The ideal customers of such pumps will tell you that the CoP from four usages is 3,000 kWh/year. Hence, solar panels are unlikely to power heat pumps and other electrical appliances in your home. It means that your solar panels might generate enough energy to power the heat but not enough to power your technology.

You will need the UK electrical grid assistance to power the rest of your house.

How Many Solar Panels Will You Need?

You will benefit from solar panels and pump combos that take 26m² or more of your roof space. Solar panels will have variable capacities in the UK, depending on their size. Usually, it is 1.6 m tall x 1 m wide with a thickness of 40 mm.

Most solar systems will have a wide surface for proper function, and the cost will vary.

The number of solar panels required will also depend on the location, the unit usage and location. Once installed, removing or replacing it will be costly. An average UK home will require four solar panels to create a 1kW system that produces 250W.

• 4 panels = 1kW
• 8 panels = 2kW
• 12 panels = 3kW
• 16 panels = 4kW
• 20 panels = 5kW
• 24 panels = 6kW
• Twenty-eight panels = 7kW, and so on.

The 4kW system is ideal for a home with four people. It means that combining solar panels with your installed unit of pumps will depend on the people at your home. Therefore, you will need an expert to assess your roof or home and estimate the requirements.

Benefits of Panels + Heat Pump

After the initial investment, you can get off the grid with 50% of your electricity requirement. The gas emission will dissipate, and your boiler requirement will be minimal. Not only does it offer higher efficiency rates, but it also reduces the overall costs of maintenance.

This symbiotic relationship will be fruitful during the cold weather when you require to produce high amounts of heat. Hence, the benefits are:

• You get full-scale heating with lower costs
• Lower electricity consumption rate
• Flexibility with heat generation
• It can have cheaper and eco-friendly energy
• Reduced grid reliance and gas emissions/carbon footprint

Fun Fact: Your ground source pumps can disregard the excessive heat and store it in the solar collectors for the next season.

• Heating properties – It can produce heat for areas of 400 to 600 m²
• Requirement of solar collectors – 16 pieces
• The capacity of tank batteries – 2,000 litres
• The volume of the tank – 200 litres
• Nominal heating capacity of solar panels – 20kW
