The term Solar system is often used synonymously with Photovoltaic system (PV system) However, there are important differences between the two systems. Solar systems include various technologies for utilising solar energy, while PV systems are used specifically to generate electricity. In this article, we explain the differences, possible applications and the most important factors you should consider when choosing the right system.
Solar system vs. PV system - an overview
What is a solar system?
The term Solar system is a generic term for all technologies that utilise solar energy. There are two main types of solar systems:
- Photovoltaic system (PV system)These systems convert sunlight into electrical energy. The electricity is produced by solar modules consisting of photovoltaic cells. The energy generated can be used directly, stored or fed into the grid.
- Solar thermal systemThese systems utilise solar energy to generate heat. They are primarily used to heat water or to support the heating system. Here, the sun's energy is not converted into electricity, but into heat.
What is a PV system?
One Photovoltaic system (PV system) is a specific type of solar system that converts sunlight directly into electricity. This process takes place via solar cells contained in the solar modules. PV systems are widely used in Germany as they offer an environmentally friendly and sustainable way of generating electricity while reducing energy costs.
Different functions of solar system and PV system
Power generation with PV systems
The main purpose of a PV system is to generate electricity. This system produces direct current, which is converted into alternating current via an inverter so that it can be used in households and businesses. The energy generated can either be consumed directly, stored in a battery storage system or fed into the public grid.
Heat recovery with solar thermal systems
In contrast, solar thermal systems do not generate electrical energy, but heat. These systems consist of solar collectors that absorb solar radiation and use it to heat water or air. Solar thermal systems are often used in combination with conventional heating systems to produce hot water or to relieve the heating system.
Solar thermal vs. PV in a detached house
Imagine you own a detached house in Nuremberg. You would like to reduce your electricity costs as well as your heating costs. One PV system covers your electricity needs, while a Solar thermal system helps to produce hot water and support the heating system. Both technologies complement each other and offer comprehensive utilisation of solar energy.
When is which system worthwhile?
Use of PV systems
PV systems are particularly worthwhile for households and businesses with high electricity consumption, especially during the day when the sun is shining. The energy generated can be used directly, and feed-in tariffs allow surplus electricity that is not consumed to be fed into the grid. A Energy consultant from the network of my-home.de can help you decide whether a PV system is the right choice for you.
Use of solar thermal systems
A solar thermal system is particularly useful if you have a high demand for hot water. In the summer months, such systems can usually cover the entire hot water requirement, while providing heating support in the colder months.
Solar system or PV system - Which solution is right for me?
- Analyse electricity demand: If you mainly want to save electricity, a PV system the right choice. Use one Energy consultant, to carry out a precise needs analysis.
- Take heating requirements into account: If the focus is on domestic hot water preparation or heating support, a Solar thermal system more sensible.
- Combination of both systemsIn many cases, a combination of PV and solar thermal systems is ideal for efficiently covering both electricity and heating requirements.

The difference between a solar system and a PV system - making an informed decision
The choice between a Solar system and one PV system depends on your individual needs. While PV systems generate electricity, solar thermal systems specialise in heat generation. Both technologies offer advantages, and sound advice can help you find the right solution for your home. Benefit from the expertise of my-home.de, to make the right decision for your energy supply.
Frequently asked questions (Q&A)
A PV system generates electricity, while a solar system can also be used to generate heat (solar thermal energy).
Yes, many homeowners combine PV and solar thermal systems to utilise both electricity and heat efficiently.
A PV system converts sunlight into electrical energy. The direct current generated is converted into alternating current via an inverter.
A solar thermal system reduces the costs for hot water and heating, especially in the summer months when the hot water demand can be completely covered.
Yes, PV systems also produce electricity in diffuse light, but less than in direct sunlight.
The amount of electricity depends on the size of the system, the orientation and the solar radiation. An energy consultant can provide you with a precise calculation.
An energy consultant from the my-home.de network can provide you with comprehensive advice and support with planning.
