“The main challenge was building and designing restrictions, but final result is accepted by the city and also client is very happy.” — Installer SigmaSystems OÜ

In the heart of Tallinn, nestled an old residential house surrounded by towering trees that are protected by law. While roof-top solar is a natural choice for the homeowner, shading and the stringent local restrictions still pose challenges to the project. But Hoymiles microinverters proved to be the game-changer for this project.

Shading is not a problem

Traditional string solar inverters operate at the string level, meaning that the performance of the entire solar array is influenced by the shading of even a single panel. This is apparently not an ideal solution for this house whose roof can be shaded by the surrounding trees every now and then.

Hoymiles microinverters offer module-level power production, ensuring that each solar panel operates at its own optimal conditions without being dragged down by under-performing panels. This means that even if some panels are in shadows, other panels in the array would still operate as usual and minimize the energy loss of the whole system.

Innovative design for best value performance

Oftentimes, microinverter systems are known as matching one microinverter with one panel. Hoymiles pushed the envelope by integrating multiple input channels into one microinverter. The HM-1200 model features four input channels, meaning that it can be connected to four solar panels at once. That is why the 20 solar panels installed on the rooftop only need five microinverters.

With this compact and innovative design, you can get the best value performance out of Hoymiles microinverters and achieve the optimal cost-effectiveness.

24/7 safety

With the DC side voltage constantly below 60 V for Hoymiles microinverter systems, there are never electrical shocks or fire hazards.

Hoymiles microinverters are also widely applied in commercial projects, like this gas station project also completed by SigmaSystems.

As the demand for sustainable energy solutions continues to grow, our commitment to innovation ensures that our products remain at the forefront, empowering homeowners to embrace solar energy, even in the most challenging environments.
