Are solar panels a good investment in 2025?
Solar panels are not only an environmentally friendly solution – they are also very much an economic investment that in 2025 is more attractive than ever before. With rising electricity prices, better technology, and new opportunities for grid balancing and intelligent control, it is possible to achieve high savings and a short payback period.
Concrete numbers – what can you save?
Let's take a typical scenario for a household with an annual electricity consumption of 8,000 kWh and an electricity price of approx. DKK 2.50/kWh: Note: With grid balancing and intelligent control, you can earn up to DKK 3,000–5,000 annually just by selling electricity, storing surplus, and helping to balance the electricity grid.
Why is the payback period shorter now?
Electricity prices are historically high – and are expected to rise further. Batteries and inverters have become both cheaper and more advanced. The panels we use are UV-coated and extremely light-sensitive – so you also produce electricity in cloudy weather and during the winter months. With intelligent control, every single kWh is optimized for your own consumption, storage, or sale. You can utilize flexibility and sell electricity dynamically via grid balancing.
Taxes and duties?
Sales up to DKK 7,000 annually are tax-free for private individuals. If you have a battery and participate in grid balancing, in many cases, you can achieve a high net profit without tax. In certain cases, you can also get VAT back on part of the investment – we will advise you.
Long-term value – more than just economy
You future-proof your home and make it more attractive for sale. You become independent of the electricity grid – and have electricity, even during outages (with a battery and hybrid inverter). You reduce your CO₂ footprint and actively contribute to the green transition. You feel the benefits from the first month – both economically and mentally.
