“Our choice of Solartag was the result of a long process, where we found that Solartag was by far the best on the market. The silky matte surface, which almost resembled slate, was exactly what we were looking for. Our newly built summer house was to replace the house that my father had built on the plot.
The old house had some defects that could not be repaired, and therefore it was demolished and rebuilt with new materials. For us, it was about the new house being sustainable and future-proof with both geothermal and solar energy.
Our geothermal system can provide cooling via a compressor and 300 m of hoses on the plot. Here we achieve 4 kW out of every 1 kW that is obtained from solar energy on the roof. In our calculation with a payback period of almost 10 years, you don’t just have to look at the roof tiles versus Solartag. You also have to look at the entire economy of “Get free electricity – that’s what’s interesting. It’s been important to know that it’s a roof that will last for the next generation.”
“We probably overshot the target in choosing the size of the plant. Especially in July and June, we produce far more than we need. But then it’s smart that you can store it in your battery or your electric car, so you can drive for free all summer long. And finally, you’re just better off in the dark months. It doesn’t matter that you can deliver your surplus back to the grid.”
