Welcher Gewinn steckt in Ihrer Immobilie?
Using the sun as an inexhaustible source of energy and reducing your electricity bill at the same time - this is possible thanks to photovoltaics (PV). In this blog post, I will guide you through all the important aspects of PV systems. From planning and installation to maintenance, you will learn everything you need to know to realize your own green energy source.
What is photovoltaics (PV)?
Photovoltaics is the direct conversion of sunlight into electrical energy using solar cells. PV systems consist of several components, including solar modules, inverters and mounting systems. They can be installed on roofs, facades or as ground-mounted systems.
Advantages of PV systems
- Environmentally friendly: PV systems produce clean electricity and help reduce CO2 emissions.
- Reduce electricity costs: With a PV system, you reduce your electricity purchase from the grid and save money in the long run.
- ndependence: You become less dependent on rising electricity prices and energy suppliers.
- Subsidies: There are often government subsidies and feed-in tariffs that reduce the investment costs.
Planning a PV system
When planning a PV system, you should consider the following points:
1. Determination of requirements: Analyze your annual electricity consumption to determine the appropriate size of your system.
2 Roof analysis: Not every roof is suitable for PV modules. The orientation, inclination and condition are decisive.
3 Check shading: Trees or neighboring buildings can affect the yield of your system.
4 Economics: Calculate whether the system is worthwhile for you. Consider the purchase costs, subsidies, feed-in tariffs and your electricity cost savings.
Installing a PV system
The installation of a PV system requires specialist knowledge and should be carried out by qualified specialist companies. Certain guidelines must also be observed for connection to the public grid.
Subsidies and financing
There are various subsidy programs in Germany that support the purchase and installation of PV systems. Find out about current funding opportunities from your local authority, your federal state or at federal level.
Maintenance and operation
PV systems are largely low-maintenance. Nevertheless, you should carry out regular inspections to ensure the performance and safety of your system.
Typical questions before buying a PV system:
- What output should my PV system have?
- How much does a PV system cost?
- What subsidies can I take advantage of?
- How long is the amortization period?
