Green energy with Fairpris and exclusive member discounts

Green energy is not just about sustainability – it is an investment that gives you several benefits:
• Lower electricity or/and heating bills
• Increased home value and comfort
• Intelligent management of your home
• Possibility to earn money on surplus electricity and grid balancing
Fairpris is Denmark's largest supplier of solar cells and battery solutions. They have a solid reputation on Trustpilot, have their own installation company and electricity company that buys back your surplus electricity. And they offer you high discounts on solar cells and battery solutions as well as air to water heat pumps.
Solar cells and batteries
Fairpris's flagship product is AEG EcoHome—a fully integrated solution combining solar panels, an inverter, and a battery into a single unit from the quality German brand AEG. It offers a simple, well-designed system featuring the market's longest product warranty and a clean, minimalist aesthetic that blends discreetly into your home's façade or utility room.
The solar panels allow you to generate your own electricity, while the battery stores low-cost energy for use during times when electricity prices are high. The system automatically manages battery charging and discharging, enabling you to capitalize on electricity market price fluctuations without having to monitor spot prices yourself. Electricity prices can spike dramatically, especially during the winter months; the battery helps smooth out your costs by storing cheap electricity in advance, which you then use when prices peak.
If you own an electric vehicle, the intelligent control system can significantly reduce charging costs—during periods of high solar output, charging can be virtually free. The higher your electricity consumption, the greater the total savings gained by meeting your needs with self-generated and stored power rather than purchasing electricity from the grid at full price. The combination of solar panels, a battery, an electric vehicle, and a heat pump is where the investment truly pays off, and the payback period has become increasingly attractive.
You have a complete overview via an app, allowing you to monitor real-time electricity flows between the grid, solar panels, battery, household consumption, and EV charging. The system operates automatically, though you can also influence the flow yourself if you wish to optimize performance.
The Danish electricity grid is occasionally overloaded and requires balancing to maintain a stable frequency. By making a portion of your battery capacity available to the grid, you can receive compensation—a form of passive income generated through grid balancing, in addition to the savings on your own electricity bill. You have full control directly from your mobile phone, allowing you to monitor production, consumption, and earnings in real time, while surplus electricity is sold automatically.
Installation takes just two days from start to finish. Slots are currently available, but installation appointments fill up quickly as we approach winter and the season of high electricity prices.
Heat pumps
You can often significantly cut your heating bill with an air-to-water heat pump. If you still heat your home with oil or gas, there are substantial savings to be made before the cold months set in. By replacing an aging boiler with a modern air-to-water heat pump, you can cut your heating bill by up to 70%.
In practice, this means saving thousands of kroner every year—money that is far better spent on your savings or your daily budget.
At the same time, you avoid the hassle: an air-to-water heat pump is a reliable, fully automated solution that practically takes care of itself. No more ordering fuel, cleaning boilers, or worrying about unpredictable gas prices—you simply enjoy steady, comfortable warmth throughout the house all year round.
An air-to-water heat pump provides efficient heating and hot water year-round, making it an excellent choice for replacing oil, gas, or pellet boilers, which remain expensive to run. Switching to a heat pump eliminates your reliance on these fuels.
Please note that the Danish Energy Agency’s heat pump subsidy scheme opened on February 5, 2026, offering a potential grant of DKK 27,000 this year. The application process for state subsidies can sometimes be complex. That is why Fairpris offers to handle the entire application on your behalf via a power of attorney, ensuring a simple, worry-free process so you can focus on the result rather than the paperwork.
Remember: To qualify for the DKK 27,000 grant, certain technical requirements must be met. You can find these details via the Danish Energy Agency, and naturally, you can also find information at Fairpris. In addition, you can take advantage of the tax deduction for skilled labor regarding the installation of the heat pump, which further improves the project's overall financial viability.
