Is a photovoltaic system worthwhile? Everything about acquisition costs and payback period

Advantages of a PV system

With rising energy prices and increased environmental awareness, solar energy has become a popular alternative. A photovoltaic system offers the significant advantage of generating environmentally friendly electricity directly from your roof, allowing households to save on energy costs in the long term and reduce their dependence on electricity providers.

Costs & Financing

As described above, the acquisition costs for a PV system range from €8,000 to €12,000 for a typical system for private households. Here, too, there are options for financing the investment through subsidies and loans, which can reduce the cost and increase profitability.

Example calculation for amortization

How long does it take for a PV system to pay for itself? Let's assume a 5 kWp system costs €10,000 and produces approximately 4,500 kWh of electricity annually. If a household uses all of this electricity itself, saving 35 cents per kWh, that results in annual savings of approximately €1,575 . This means the system could pay for itself in approximately 6-7 years – depending on electricity prices and individual conditions.

With memory or without?

An energy storage system increases independence, as excess electricity can be stored and accessed when needed. However, a storage system increases the initial cost by approximately €5,000 to €8,000 . Whether this is worthwhile depends on individual needs.
