How do Solar Panels Work?

It's essential to consider how solar panels function before discussing how they may power heat pumps. Solar panels are made up of numerous photovoltaic (PV) cells, which are crucial in the conversion of sunlight into electricity. Photovoltaic (PV) cells found in solar panels are what turn sunlight into energy. Semiconductor components used in PV cells absorb photons of sunlight and emit electrons as a result. This release of electrons generates a direct current (DC) of electricity. The circuit that captures these electrons causes a flow of electricity. An inverter is then used to convert the direct current into alternating current (AC), which is the type of electricity used in homes and businesses.

Using Solar Panels to Power a Heat Pump

A heat pump is an equipment that moves heat from one location to another using refrigeration technology. Depending on the mode of operation, it may either be used to heat or cool a structure. Heat pumps are highly efficient, often producing three to four times more energy than they consume. Solar panels can be used to provide the power needed for heat pumps to function.

A heat pump can be powered by energy produced by solar panels. The number and size of solar panels, the quantity of sunshine they get, and their efficiency are only a few of the variables that affect how much power is produced by solar panels. For instance, a typical domestic heat pump might require between 2,000 and 5,000 kilowatt-hours (kWh) per year.

When utilising solar panels to power a heat pump, it's crucial to take their efficiency into account. The amount of sunshine that is turned into power is known as a solar panel's efficiency. Efficiency rates can vary significantly, with most modern panels converting between 15% and 22% of the sunlight they receive into electricity. A heat pump may be powered by more electricity produced by higher efficiency solar panels.

Sizing your Solar Panel System 

You must carefully size your solar panel system if you want to use them to power a heat pump. Accurate sizing ensures that your system can meet the energy demands of your heat pump throughout the year. In order to do this, you must calculate how much power your heat pump needs and how much sunshine your solar panels will get.

To determine the size of your solar panel system, you need to assess your location’s solar potential. For example, southern parts of the UK generally receive more sunlight compared to northern regions.

It is advised that you seek the guidance of a qualified heating engineer because calculating the size of your solar panel system may be a challenging task. They can guarantee that your solar panel system is installed properly and assist you in determining the proper size for it. A professional can also help you consider factors such as roof orientation, shading, and the tilt of the panels, all of which can affect the efficiency of your solar system.

Benefits of Using Solar Panels with a Heat Pump

Combining solar panels with a heat pump can lead to significant cost savings on your energy bills. By generating your own electricity, you reduce your reliance on the grid and protect yourself from rising energy prices. Additionally, using renewable energy reduces your carbon footprint, contributing to a more sustainable environment.

Another advantage is the potential eligibility for government incentives and rebates. In the UK, schemes such as the Renewable Heat Incentive (RHI) provide financial support for homeowners who install renewable heating technologies, including heat pumps.
