Solar power: a sustainable investment in the future

February 22, 2024

The sun - an inexhaustible source of energy that has existed for billions of years and provides us with light and heat every day. With the growing importance of climate protection and the need to move away from fossil fuels, solar power is increasingly becoming the focus of consumers, politicians and businesses. But what exactly is solar power, how does it work and why should you opt for this form of energy? Find out everything you need to know about solar power in this comprehensive blog post.

What is solar power?

Solar power, also known as photovoltaic energy, is electrical energy that is generated by converting sunlight using solar cells. This type of energy generation is a renewable energy source and has the potential to make a significant contribution to the energy transition. In contrast to conventional sources of electricity such as coal, oil or gas, whose supplies are finite, solar energy is available almost indefinitely.

How is solar power generated?

Solar power is generated in photovoltaic systems. Such systems consist of many individual solar cells, which in turn are combined to form solar modules. Solar cells consist of semiconductor materials, usually silicon, which generate electrical voltage when exposed to light. When sunlight hits a solar cell, electrons are set in motion and an electric current is generated. This can be used directly or fed into the public power grid.

The advantages of solar power

- Sustainability: Solar power is a clean and environmentally friendly source of energy. No harmful emissions or waste products are produced when generating electricity.
- Independence: With your own photovoltaic system, you can become partially or completely independent of external electricity suppliers.
- Cost savings: Once the initial investment has been amortized, homeowners can benefit from lower electricity costs.
- Subsidies: Many countries offer financial incentives such as feed-in tariffs or tax breaks for the installation of photovoltaic systems.
- Increase in property value: Houses with solar systems can increase in value as they are future-proof and cost-efficient.

What should you look out for when purchasing a photovoltaic system?


- Location: The output of a photovoltaic system depends heavily on the geographical location. The yield is naturally higher in sunny regions.
- Orientation and inclination: The solar modules should be optimally aligned with the sun in order to achieve the highest possible yield.
- Shading: Surrounding trees, buildings or other objects can impair the efficiency of the system by casting shadows.
- Size of the system: The dimensions of the photovoltaic system should be adapted to your own electricity consumption.
- Quality of the components: High-quality solar modules and inverters are crucial for the longevity and efficiency of the system.
- Professional installation: An installation carried out by experts guarantees the safety and maximum performance of the system.

The future of solar power

Solar energy technology is developing rapidly. The efficiency of solar cells is increasing and the cost of solar power is falling. Experts believe that solar power will be competitive with conventional energy sources in the near future and will be able to cover an even greater proportion of our energy needs. Countries such as Germany are pioneers in the expansion of solar energy and show that the switch to renewable energies is possible.

What is the economic viability of solar power?

The cost-effectiveness of solar power has improved significantly in recent years. The prices for solar modules have fallen, while the energy costs for conventional electricity have tended to rise. In many cases, solar power has already reached grid parity, which means that the cost of self-generated solar power is lower than the price of electricity from the energy supplier. In addition, government subsidies help to make investing in a photovoltaic system more attractive.

The sun shines for all of us - let's use its power for a cleaner and greener future!
