By installing your own photovoltaic power plant on your roof, you will reduce your energy consumption costs. The main reason for choosing photovoltaics is that you will not be as dependent on energy from suppliers, so you will no longer have to worry about fluctuating prices. In addition, you will be insured against possible power outages. The battery storage system can start an emergency mode when the power supply is interrupted and keep your household appliances running.
Purchasing photovoltaics will save you worries for up to 25 years. That is the estimated lifespan of solar panels on the roof. In short, solar energy offers a comprehensive solution—heating, electricity generation, and water heating.
The cheapest solution is photovoltaics with water heating Photovoltaics generate electricity mainly in the morning when the sun is strongest. If you do not use it immediately, you can direct the surplus to water heating, for example.
A certain disadvantage is that excess electricity can either be lost or sent to the distribution network without financial gain. With this solution, you will have hot water "for free" for half of the year. To achieve maximum savings, use the delayed start function on your dishwasher or washing machine.
The main advantage of photovoltaics with battery storage is that you consume all the electricity you generate yourself, without any overflow into the distribution network.
Heat pump with photovoltaics In summer, you will be self-sufficient thanks to solar panels that convert sunlight into electrical energy. Solar panels collect the most energy when the sky is blue and the sun is shining, but they can still generate electricity even when it is cloudy, just at a reduced output.
During the winter months, a heat pump offers a solution that requires very low operating costs. Photovoltaics with a heat pump is suitable for family homes with lower heat loss and a lower-output heat pump.
Do you have an electric car? Then your investment in photovoltaics will pay for itself even faster. If you have already invested in an electric car or are considering purchasing one, then you will appreciate photovoltaics on your roof even more. With an electric car, installing a photovoltaic power plant at home makes even more sense. Thanks to the combination of photovoltaics and a charging station, operating an electric car is really affordable. In addition, an electric car does not have to be just a consumer of zero-emission electricity from the sun, but in a smart home it can also serve as a robust battery storage device for surplus energy from the photovoltaic power plant.
