Shadows on solar systems: How power optimizers can help
A photovoltaic system increases the value of your property quite directly. The reason? It reduces your running costs because you produce some of your own electricity and need to draw less from the grid. This makes you less dependent on electricity price fluctuations – and, let's be honest, who wants to pay constantly rising energy costs? If you have surplus energy, you can feed it into the grid and receive compensation for it – it's basically extra income from the sun. If you combine the PV system with a heat pump, your heating costs will also decrease and the energy efficiency of your home will increase significantly. All of this signals to buyers that you have invested in modern, sustainable technology. Pretty convincing when it comes to increasing the value of your home with photovoltaics.
Advantages
Selling a house with a solar power system? A photovoltaic system significantly reduces ongoing electricity costs in the household—a clear advantage for operating cost calculations and a plus point in property valuation. Generating your own electricity also means you are less dependent on electricity prices, which can fluctuate greatly. This provides planning security and long-term cost savings, which increase the attractiveness of the property value. Installing a PV system also has a positive effect on the building's energy performance certificate. A better energy efficiency rating increases the real value of the property, which is particularly relevant when selling or renting. High self-consumption of the electricity generated maximizes the economic efficiency of the system. The more electricity is used directly, the greater the financial benefit to the owner – which is also reflected in the market value of the property. A PV system also signals a sustainable use of resources. This makes the property more attractive to buyers and tenants who value environmental awareness. In addition, surplus electricity can be fed into the public grid, generating additional income and further increasing the property value.
A photovoltaic system is essentially an upgrade for the property – both in terms of energy efficiency and appearance. Generating your own electricity not only improves your operating costs, but also makes the entire building more attractive and sustainable. This is not just a nice side effect – it has become a pretty strong selling point when it comes to selling or renting out a property. A PV system means lower utility costs, a better environmental balance, and the property stands out significantly from comparable properties without such technology. In short: if you are committed to sustainability and value retention, PV is a must.
Tips
PV system plus heat pump? Technically speaking, this works quite efficiently. The electricity you generate yourself directly powers the heat pump, which significantly reduces energy costs because you need less electricity from the grid.
Regarding system orientation: Although south-facing systems deliver the highest performance, east- and west-facing roofs are also a good option. The advantage? Electricity production is spread more evenly throughout the day, which increases self-consumption. This means you use more of your own electricity and less from the grid.
And don't forget: there are various government subsidy programs for photovoltaic installations. Such grants and loans can significantly reduce investment costs. If you are planning to install a system, be sure to find out about the latest subsidy options.
