They also contribute to reducing the reliance on the main power grid and have a positive impact on the environment.

Micro Inverters

A small micro inverter with a simple yet functional design, showing its connection points for individual solar panels.

Micro inverters offer a unique advantage in solar power systems. Unlike traditional string inverters, each micro inverter is connected to a single solar panel, allowing for individual panel optimization. This means that even if one panel is shaded or has a lower performance due to some reason, it won't affect the overall output of the entire system. They are easy to install, highly efficient in converting DC to AC power, and provide better flexibility in system design, making them suitable for both residential and small commercial solar installations.

Roof - Integrated Photovoltaic Power Stations

A roof-integrated photovoltaic power station that seamlessly blends with the roof tiles, creating an aesthetically pleasing and efficient energy solution.

Roof - integrated photovoltaic power stations combine the functionality of solar power generation with the aesthetics of building design. These stations are custom-designed to fit directly onto rooftops, replacing traditional roofing materials in part or in whole. They not only generate clean energy but also enhance the overall look of the building. With advanced installation techniques and durable materials, they can withstand the elements while providing a long-term and reliable source of electricity, making them an ideal choice for both new construction and retrofit projects.
