More value for your home? How a solar system affects the property value after renovation
In view of rising energy costs, growing climate awareness and stricter legal requirements relating to energy efficiency, many homeowners are asking themselves the question: Is it worth investing in a solar system - also in terms of property value?
The answer is increasing: Yes. A photovoltaic system (PV system) can not only reduce running costs, but also noticeably increase the market value of a property. In this article, you will find out how solar energy affects the resale value, the attractiveness for buyers and the categorisation in the energy efficiency class - and why sustainability is a strong selling point today.
1. increasing property value through solar energy
Solar systems as an increase in value - not only idealistic
While a modern kitchen or a new bathroom are often subjective upgrades, the increase in value through a PV system can often be quantified more clearly. According to studies by property portals and energy institutes, the market value of a property can be increased by a solar installation. by 4 to 10 % increase - depending on the location, size of the system and general condition of the house.
Example:
A house with an estimated market value of €500,000 could rise to as much as €525,000 with a PV system worth €15,000 - provided that the system is modern, well dimensioned and ready for operation.
Arguments for buyers
- Lower energy costs:Buyers know that they can save on electricity costs in the long term - a big plus point when making their decision.
- Independence:With an electricity storage unit or in combination with a heat pump, self-consumption increases - an attractive offer in times of fluctuating energy prices.
- Longevity:Modern solar systems are low-maintenance and have a service life of 25 years or more - a sustainable investment for both sides.
2. energy efficiency class as a sales factor
Why the energy performance certificate counts
When selling a property, the Compulsory energy certificate - and more and more buyers are paying attention to the Energy efficiency class, which ranges from A+ (very efficient) to H (very inefficient), similar to household appliances.
The highlight: A PV system measurably improves the energy balance of the house and can therefore contribute to a better efficiency class. This has several advantages:
- Lower ancillary costs:Particularly relevant for buyers - because those who consume less energy save money every month.
- Better financing conditions:Banks often grant more favourable interest rates or special subsidy programmes for energy-efficient properties.
- Image factor:A house with a good energy balance conveys modernity, environmental awareness and future security.
What counts in the energy performance certificate?
The evaluation includes the following data, among others:
- Heating type and energy
- Insulation standard
- Window quality
- Renewable energy sources such as solar power or solar thermal energy
A retrofitted PV system therefore not only improves the ecological conscience - but also the ranking of the house on the property market.
3. sustainability as a sales argument
A social change
Climate protection, CO₂ reduction and energy self-sufficiency are no longer niche topics. More and more people are consciously looking for sustainable construction methods and a future-proof energy supply when buying a home.
Buyer groups with a particular interest in sustainability:
- Young families with environmental awareness
- Investors with a focus on ESG criteria
- Buyers who want to move away from fossil fuels
- E-mobility users with an interest in producing their own electricity
Anyone investing in a solar energy system today is therefore targeting a growing target group for whom environmental friendliness and long-term cost savings are decisive purchasing criteria.
Combinations are the trump card
A house becomes particularly attractive if the solar technology is part of a holistic energy concept:
- Photovoltaics + electricity storage = high proportion of self-consumption
- PV + heat pump = self-sufficient heat supply
- PV + wallbox = own charging station for electric cars
These Synergy effects further increase the attractiveness and justification of a higher price.
Conclusion: Solar systems are worthwhile - also for the property value
Today, a photovoltaic system is far more than just a contribution to the energy transition. It is a tangible Value-enhancing instrument, which improves both the market value and the chances of selling a property. It is particularly worthwhile to include PV installation in the planning of energy-efficient renovations or conversions - not least because subsidy programmes such as those offered by the KfW or BAFA make it easier to get started.
To summarise:
- A PV system can increase the property value by several per cent
- The energy performance certificate is improving - a strong argument for buyers
- Sustainability is increasingly becoming a purchasing factor
- The investment pays off in the long term for both owner-occupiers and sellers
If you want to upgrade your property, solar energy is doubly worthwhile - for your bank account and for the planet.
