From Sunshine to Savings: The Mueller Family Uses Customized Solar Energy+Energy Storage Systems to Power Their Daily Homes

Client: Mueller Family

Location: Freiburg, Baden-W ü rttemberg, Germany

Industry: Residential Owners

System: 10.2 kW rooftop photovoltaic system, 15 kWh lithium-ion battery energy storage

Challenge: Achieve energy independence, reduce high electricity costs, and sustainably power two electric vehicles.

Solution: Provide a complete and efficient solar energy+energy storage solution.

Challenge: Soaring energy bills and thirst for sustainable development

The M ü ller family lives in the sunny city of Freiburg, Germany, and there are two key factors: the continuous rise in electricity prices and a strong personal commitment to reducing carbon footprint. They have two electric cars and the household consumes a lot of energy. They are frustrated with their dependence on the power grid, especially during peak electricity prices, and they hope for a solution that allows them to use their own clean energy day and night.

Mr. Klaus M ü ller explained, "We invest in electric vehicles to be more environmentally friendly, but if charging comes from fossil fuels, it feels incomplete. We need a system that can not only power our homes, but also our cars, truly enabling us to achieve energy self-sufficiency

Solution: Tailored photovoltaic system

After evaluating several suppliers, M ü llers chose us. We not only sell components; We provide a complete and optimized solution.

Efficient solar panels: Our team has installed a sturdy 10.2 kW high-quality solar panel array on the south facing roof, perfectly tilted to maximize the capture of sunlight throughout the year.

The core of the system: The cornerstone of this project is our 15 kWh lithium-ion battery energy storage device. This type of battery stores excess solar energy generated during the day, rather than sending it all back to the grid at a slower rate. Then, these stored energies are used at night to power households.

Seamless Professional Installation: As shown in the attached image, our certified technicians performed a perfect installation to ensure the perfect integration of the system with the home's electrical infrastructure without compromising the integrity of the roof.

Result: Transformation and tangible benefits

In the first month of operation, the M ü ller family witnessed a significant shift in energy usage.

Electricity bill significantly reduced: This household's electricity bill has decreased by over 90% from the power grid Now, in long periods of cloudy weather, they only receive minimal electricity from the power grid.

True energy independence: The battery system provides electricity during the evening rush hour, and households no longer worry about tariffs on usage time. They have achieved a high level of energy security.

Sustainable electric vehicle charging: They mainly use the solar energy generated by their own roofs to charge electric vehicles, making their transportation truly carbon neutral.

Increasing property value: This house is now more attractive in the market with a modern and cost-effective energy system.

As shown in the picture, the installation team is professional and efficient, "Ms. Mueller said. The best part is opening our energy application and seeing us fully powering our entire home and car with sunlight. It's powerful. Not only do they install panels; they also provide a complete energy solution that changes our lives
