I have been waiting for the battery market to take off in Finland for many years. Now, at the year 2025, the boom is finally here.

From my very first days in the solar industry, people have asked me if it makes sense to buy a home battery along with solar panels. For a long time, my answer was no. I think that home batteries didn't make much (economic) sense. Personally, I believed (and still believe) that the real breakthrough will come with the rise of V2G (Vehicle-to-Grid) chargers, which will change the way we store and use energy.

In 2023, interesting news started coming from the battery market, and best of all, from the Nordics. Through RAULI, I was in regular contact with professionals from various countries, and I started hearing about a battery boom in Sweden. Thanks to the reserve market, homeowners were making real money with their batteries. It made battery investments much more profitable. The demand was so high that there was even a shortage of electricians in Sweden. I ended up sending a few of my Aurinkotekniikka guys over there to help with installations. That is a story of its own.

In the fall, I heard more good news, again from the Nordics. A Danish company, Emaldo, was bringing excellent battery products to the market, allowing homeowners to join the local reserve market. I flew to the Solar Energy Expo in Warsaw to learn more about their products. There, I met Tobias Jung, a talented guy I had previously met in Sweden. By then, he had taken over Emaldo’s European sales. After Warsaw, I made a trip to the Czech Republic to meet with ScandiConcept s.r.o. team and get their perspective on Emaldo.

At this stage, no one in Finland had started working with Emaldo. When I met Emaldo’s CEO Steffen Bjerregaard at Intersolar, it was the perfect moment. We quickly agreed to start a partnership between Aurinkotekniikka and Emaldo.

After that, things moved quickly. We launched marketing campaigns on multiple platforms simultaneously and managed to create a positive buzz around the new product in no time.

Finally, there was a solution for consumers that offered a good ROI. In addition to storing daytime energy and preparing for electricity price spikes, Emaldo battery owners in Finland can now participate in the reserve market managed by Fingrid, creating an annual financial benefit of over 2,000 euros.

Of course, Aurinkotekniikka is not the only company offering Emaldo to consumers, but thanks to our successful market entry and efficient sales process, we have already reached seven-figure sales.
