Can a Heat Pump Be Run on Solar Energy?

People are more worried than ever before about the future of our planet. More and more Australians are taking steps to reduce their home environmental impact. Insulating your home better to reduce heat loss, recycling paper, cardboard, and glass, and disposing of food scraps in a food waste caddy are all good places to start.

More than a million Australian households are using solar panels to generate clean electricity, a figure that doubled between the years 2018 and 2019. Although the upfront cost of solar panels may deter some people, a heat pump and solar panels can provide nearly all of the heat needed to keep a house habitable.

Is Solar Energy Adequate to Power a Heat Pump?

Heat pumps are possible be used in tandem with photovoltaic arrays to provide both space heating and hot water domestically in a sustainable manner. Depending on the scale of the solar array, it’s entirely possible that you wouldn’t need any additional electricity to power your heat pump. In other words, during the daytime hours only, you would produce more energy than you could use in a year.

Thermal solar energy and photovoltaic solar energy are the two main categories of solar power.

Using solar thermal to heat your hot water is an efficient way to cut down on the amount of electricity your heat pump needs to operate.

However, photovoltaic solar (PV) systems are able to directly harness the sun’s energy and transform it into usable electricity. This power can be used to supplement the energy provided by your heat pump, lowering your reliance on grid electricity, which is produced primarily through the combustion of fossil fuels.

Power output from solar arrays is typically measured in kilowatts (kW). This figure represents the average power output of the panels during peak sunlight hours. About 3–4 kW is the typical system size, which is also the maximum power that can be generated on a very clear, sunny day. This number could be lower on cloudy days or when the sun is lower in the sky, such as in the mornings and evenings. A four-kilowatt system requires about 26 square metres of roof space but produces 3,400 kilowatt-hours of electricity annually.

But, Is That Sufficient?

A four-kilowatt (kW) solar panel array should provide nearly all the power you need, considering that the typical Australian home consumes around 3,700 kWh per year. An insignificant amount of power would have to be drawn from the mains.

One thing to keep in mind is that most homes don’t use heat pumps but instead rely on boilers for their heating but also hot water needs. These homes will have a higher reliance on natural gas and a lower reliance on electricity. However, heat pumps consume more electricity; even the most efficient models (CoP 4) consume around 3,000 kWh annually.

The solar panels in your home should generate enough electricity to heat your residence and water, but they probably won’t generate enough to run your heat pump and the rest of your appliances without some help from the utility company’s power grid. The above calculations suggest that the solar panels will be able to supply roughly half of the household’s total electricity needs, with the remaining half coming from the electrical grid (or coming from other renewable sources, such as a wind turbine if your house has one installed).

To Power a Heat Pump With Just Solar Panels, How Many Would Be Required?

The greater the number of solar PV panels that can be installed on a roof, the better. Having so few panels would mean that even the tiniest electronics would struggle to get any juice.

As was previously mentioned, a solar panel system to power a heat pump would have to be at least 26 square metres in size, though larger systems are preferable.

Solar panels can be made in a variety of sizes by different companies, but even the smallest ones are quite sizable. Each panel is approximately 1.6 m in height and 1 m in width, but they appear smaller on a house because of their proportions. About 40 mm is the thickness of these. The panels’ surface area must be large in order to receive maximum sunlight.

Depending on the desired output of the system, different configurations of panels will be required. Each kilowatt (kW) of solar power requires four panels. As a result, four solar panels are required for a one-kilowatt system, eight for two kilowatts, twelve for three kilowatts, and sixteen for four kilowatts.

The latter increases the area by about 26 square metres.

Remember that a four-kilowatt system is perfect for a three or four-person household. A 5 or 6-kilowatt system, which could demand up to twenty-four panels and will take up to thirty-nine square metres more space, may be necessary for a community with more than this many people.

It’s possible you’ll need more or less, depending on factors like the slope of your roof and the climate where you live.

If you want to use solar panels to energise a heat pump, you should have a qualified engineer take a look at your home first.

They can suggest ways to improve your home’s energy efficiency (double glazing, more insulation, etc.) that will decrease the amount of electricity you need to run the heat pump. If you ask them, they ought to also be capable of telling you how many photovoltaic panels you’ll need and where you can put the heat pump.

For a trouble-free installation, expert guidance is well worth the investment of time and money.

Energy Efficiency Through Solar and Heat Pumps

Solar panels have become increasingly common in Australia as a means for homeowners to generate their own electricity independently from the utility company.

Systems like these, which can use the sun’s free energy, are frequently combined with others to provide superior indoor climate control. In this context, heat pumps are a common choice among homeowners.

In addition to using renewable energy from the sun or the earth’s core, these devices also make use of the heat out from outside air or the earth’s core, allowing people to reap a plethora of benefits.

What Is an Air-Source Heat Pump?

An air-source heat pump is a heating and cooling system that uses the air outside as a source of heat. It works by using a compressor to move heat from the air outside to the inside of your home, where it can be used to warm the air or water.

This type of heat pump is typically more efficient than traditional heating and cooling systems and can be a cost-effective way to heat and cool your home. Air-source heat pumps are also relatively easy to install and maintain and can be used in a wide range of climates. They are a good choice for homeowners who want to reduce their energy consumption and carbon footprint.

What Is a Geothermal Heat Pump?

It works by using a network of underground pipes, called a ground-loop, to transfer heat from the ground to the inside of your home. In the winter, the system uses the heat from the ground to warm the air inside your home, and in the summer, it uses the cool temperature of the ground to cool the air inside your home.

This type of heat pump is very efficient and can save a significant amount of energy compared to traditional heating and cooling systems. It is also environmentally friendly, as it uses a renewable source of power and does not produce any greenhouse gases. However, geothermal heat pumps can be more costly to install than other kinds of heat pumps, so they may not be the best option for everyone.

The efficiency of solar panels can vary depending on a number of factors, such as the type of panel, the location and weather conditions, and the angle at which the panels are installed. In general, solar panels are about 15-20% efficient at converting sunlight into electricity.

This means that for every hundred watts of sunlight that shines on the panels, they will produce 15-20 watts of electricity. The exact efficiency of a given solar panel can be determined by dividing the amount of electricity it produces by the amount of sunlight it receives. It’s important to note that the efficiency of solar panels can decrease over time, so it’s important to regularly maintain and clean them to ensure they continue to operate at their maximum efficiency.

Heat Recovery Ventilation Can Be Used in Conjunction With a Combined System

Buildings with good air circulation often have exhaust air retrieval systems installed.

An integrated heat pump and solar panel system can be used in this situation to reclaim heat from the outgoing exhaust air.

This is recycled for use as space heating and domestic hot water.

The aforementioned facilities can be accumulated in some systems, which are included with the system itself. If you have these setups, you can also store solar energy for later use.

As a result, optimal operations but also savings can be experienced in light of actual energy consumption by combining these solutions. To get the most out of this system, it is important to work with trained professionals.

Carbon Emissions From a Structure Are Reduced

In addition to saving money, combining photovoltaic power with heat pumps helps reduce a building’s carbon footprint. While this is certainly important for homes, its true value lies in the commercial and office sectors.

One such application detailed a 64% reduction in a household’s carbon footprint, from 5.4 metric tonnes of CO2 emissions per year to less than 2.0 metric tonnes.

A combined solution like this can make a big difference for businesses in a country that is shifting towards more sustainable consumption and during a time when companies are increasingly concerned about their carbon footprint.

Commercial establishments benefit from energy efficiency ratings. Solar power and heat pumps make it simple to promote moral business practices that win over the public.

Using Heat Pumps in Tandem With Solar Panels Is an Excellent Way to Maximise Solar Power Benefit

Many people don’t realise that only about half of the energy produced by residential solar panels can actually be used by homeowners.

The remainder is added to the grid, eliminating the option for homeowners to save this power for later use.

Heat pumps are able to alleviate this issue significantly. Since these gadgets give off heat at cold temperatures over long periods of time, the energy required to run them is minimal and remains constant.

This means that homeowners with either an air-source heat pump or a deep geothermal heat pump can boost their solar energy consumption by about 20%.

Both Are Decreasing in Price, Which Is Good News

Affordable PV systems and heat pumps are another attractive option for property owners hoping to increase their asking price.

Rebates and incentives from the government are also likely to be made available for both options in addition to the natural price reduction that will occur.

Incentives and funding options for solar panels, in particular, are abundant. The cost of transitioning to sustainable power technology like this is greatly reduced.

Important Ideas
