Here, the aim is to reduce dependence on purchased energy by maximizing the use of local, renewable resources, while guaranteeing a high level of comfort for residents. To achieve this, an innovative hybrid solution was implemented, combining photovoltaic and hybrid solar panels, heat pumps and a district heating network.
Optimized technology for maximum efficiency
The installation is based on a combination of complementary technologies:
- 168 Dualsun SPRING 425 Shingle Black hybrid panels, which simultaneously produce electricity and heat.
- 112 Dualsun FLASH 425 Shingle Black photovoltaic panels, optimizing energy self-consumption.
- A 63 kW Qvantum Q81RS/2 heat pump, powered by the hybrid panels to maximize efficiency.
- 6 m³ of thermal storage, including 3 m³ for domestic hot water, to optimize management of recovered heat.
- A 350 kW connection to the urban heating network, providing additional energy in winter.
- 40 kWh of electrical energy storage, to smooth consumption and make better use of solar energy.
Thanks to a liquid cooling system, Dualsun SPRING hybrid panels increase their photovoltaic output by 6%, while recovering the heat generated to power thermal storage and the heat pump. Excess energy captured during the day is stored for use at night, optimizing the site’s energy management.
The district heating network comes into play when solar energy is insufficient, particularly during winter periods of high heating demand. This integration ensures energy continuity while reducing purchased energy consumption.
Impressive energy performance
The expected performance of the hybrid system is significant:
- 50% of energy needs are covered by the hybrid solar/heat pump solution.
- 40% of hot water requirements are met by the hybrid panels and heat pump.
- 62% of heating needs are supplied by this same combination.
- 50% of the electricity produced is consumed on site.
- Seasonal performance factor (SCOP) of 8.5, thanks to the integration of solar self-consumption.
- Surplus electricity in summer can be sold back to the grid.
- Primary energy consumption reduced by over 40%, from 61.4 kWh/m² to just 37.1 kWh/m².
The key role of Dualsun panels
The integration of Dualsun SPRING hybrid panels represents a major step forward for this project. By simultaneously producing electricity and heat, they optimize the site’s energy autonomy and improve the overall efficiency of the installations.
Dualsun Nordic, our partner in Sweden, played a decisive role in the design and integration of this technology. Thanks to its local expertise, Dualsun Nordic supported the implementation of this hybrid solar solution adapted to the climatic conditions and energy objectives of the project.
A model for tomorrow’s sustainable construction
The Magnolia project in Lund illustrates how the combination of hybrid solar energy, heat pumps and district heating networks can deliver outstanding energy performance.
By combining energy efficiency, reduced operating costs and a low carbon footprint, this project sets a benchmark for future sustainable residential construction.
With the commitment of Magnolia Bostad AB, Heimstaden, Kraftringen, Dualsun Nordic and Qvantum, this project proves that it is possible to build efficient housing while intelligently integrating renewable energies and existing energy networks.
