Combining solar panels with a heat pump
Combining renewable energy: solar panels and heat pumps
The combination of solar panels and a heat pump is becoming increasingly popular in modern homes and buildings. Both technologies complement each other and create a highly efficient energy system.
Solar panels generate electricity from sunlight, while a heat pump uses electricity to extract heat from the environment. By combining these technologies, a large part of the building’s energy demand can be covered sustainably.
When combined with an air-to-water heat pump, the electricity generated by solar panels can directly power heating, cooling and domestic hot water production.
What are solar panels and air-to-water heat pumps?
Solar panels convert sunlight into electricity using photovoltaic cells. This electricity can be used directly in the building, stored in batteries or exported to the electricity grid.
An air-to-water heat pump extracts heat from outdoor air and transfers it into a water-based heating system. This heat is used for space heating and domestic hot water.
Because heat pumps operate using electricity, they are perfectly suited to work together with solar panels.
Why combine solar panels with a heat pump?
By combining solar panels with a heat pump, a significant portion of the required energy can be generated on-site. The electricity produced by the solar installation can directly power the heat pump.
This reduces dependency on grid electricity and lowers reliance on fossil fuels.
- lower energy costs
- reduced CO? emissions
- higher energy efficiency
- future-proof building installation
Smart control and advanced features
Modern heat pumps include advanced control features that optimize energy usage. Heat pumps from brands such as Itho Daalderop and ALPS EXCLUSIVE include a timer function.
This timer allows specific heat pump functions to be scheduled, such as:
- heating
- cooling
- domestic hot water production
For example, the heat pump can automatically produce extra domestic hot water during peak solar production.
Additionally, many modern heat pumps are SG Ready. This means the heat pump can communicate with smart grid and energy management systems.
When surplus solar energy is available, the heat pump can automatically increase heat production and store the energy.
Thermal storage using buffer tanks
When combining solar panels with a heat pump, using a buffer tank can be beneficial. A buffer tank acts as a thermal energy storage system.
Heat produced during the day can be stored and used later when heating demand increases.
This stabilizes the operation of the heat pump and prevents frequent start-stop cycles.
Cost savings and future-proof housing
Although the initial investment in solar panels and heat pumps may seem significant, operational costs are relatively low.
Additionally, subsidies are available for heat pumps through programs such as the ISDE subsidy.
Combining these technologies reduces long-term energy costs and prepares buildings for future energy regulations.
