The increasing demand for renewable energies and ever higher electricity prices are leading many homeowners to ask themselves: When is a PV system worthwhile? Photovoltaic (PV) systems offer the opportunity to generate electricity from solar energy and thus reduce energy costs in the long term. But when is the right time to invest in a PV system and what factors should be taken into account? In this article, we look at the most important aspects and provide you with a sound decision-making aid.
Profitability of a PV system
Savings potential and electricity costs
One of the main questions when deciding in favour of a PV system is how much money you can save by generating your own electricity. The price of electricity from the grid has risen continuously in recent years. With a PV system, you can cover a large part of your electricity requirements yourself and thus protect yourself against rising energy costs. The more electricity you use yourself and the less you have to feed into the grid, the greater the savings potential.
Subsidies and financing options
Another important aspect is the subsidisation of PV systems. There are numerous government subsidy programmes that make the purchase and installation of a photovoltaic system more attractive. Grants and low-interest loans are available at both federal and state level. A competent Energy consultant from the my-home.de network can inform you about current funding opportunities and support you with the application process.
Technical aspects - When is a PV system worthwhile?
Roof pitch and orientation
Not every roof is suitable for a PV system. The optimum roof pitch for a PV system in Germany is between 30 and 35 degrees. The orientation is also decisive: a south-facing orientation is ideal as it allows the most solar radiation. However, roofs facing east or west can also be utilised economically if the system is dimensioned accordingly.
Availability of storage systems
A decisive factor for the profitability of a PV system is the storage of the electricity generated. Battery storage systems make it possible to store surplus electricity produced during the day for self-consumption in the evening. This increases the proportion of self-consumption and thus increases the profitability of the system.
Is a PV system worthwhile for me?
- Maximise self-consumptionIf you consume a lot of electricity during the day (e.g. when working from home or using electrical appliances), a PV system is particularly worthwhile as you can increase the proportion of self-consumption.
- Utilise funding opportunities: Let one of our Energy consultant to make optimum use of all available subsidies and to finance the investment in a PV system.
- Long-term planningThe investment in a PV system is usually amortised within 10 to 15 years. The longer you want to stay in your own home, the more you benefit from the savings.

Frequently asked questions (Q&A)
The savings depend on your electricity consumption, the size of the PV system and the proportion of self-consumption. An energy consultant can make an exact calculation for your situation.
Yes, there are various funding programmes at federal and state level. A competent energy consultant will help you to find the best options for your financing.
A roof pitch of 30 to 35 degrees and a south-facing orientation are ideal. Have your roof checked by a specialist to determine its suitability.
The amortisation period is usually between 10 and 15 years, depending on the size of the system and electricity prices.
A battery storage system makes sense if you want to maximise your own consumption. This allows you to use the electricity generated during the day in the evening hours.
If you produce more electricity than you consume, you can feed the surplus electricity into the grid and receive a feed-in tariff.
Yes, PV systems can also be retrofitted to existing buildings. Seek advice from an energy consultant to find the best solution for your home.
