What is solar energy?
Solar energy is an energy that comes from the sun. It is also called solar energy. It consists of light and heat energy. It is converted into electricity by photovoltaics. In this process, the sun's rays hit solar cells. This sets electrons in motion and thus generates electricity. This energy is available in unlimited quantities and is sustainable.
This type of energy never runs out and is clean. We need less of other energy sources and pollute the environment less. Solar energy therefore helps to protect nature and live sustainably.
How does the conversion of solar energy into electricity work?
To convert solar energy into electricity, we use photovoltaic systems. These contain solar cells that capture sunlight. The photoelectric effect is used. This effect helps to release electrons from a material. The electron movement creates an electrical voltage. This process is converted into electricity via contacts.
"The conversion of solar energy into electricity by photovoltaic systems is a fascinating process based on the photoelectric effect. This effect enables the solar cells to convert sunlight into electrical energy and thus contribute to the power supply."
The process begins when the sun's rays touch the solar cells. These cells are made of a material that releases electrons when it glows. The free electrons generate an electrical force through their movement.
The solar cells are connected to modules to provide more power. By connecting these modules, the voltage can be increased. In this way, electricity is made from solar energy that we can use.
Many factors influence the conversion of solar energy into electricity. These include the amount of sunlight and the quality of the solar cells. Developments in photovoltaic technology are constantly improving the efficiency of solar systems. They generate more electricity with less loss.
Solar Energy – A Renewable and Sustainable Electricity
Converting solar energy into electricity is good for our future. This is because photovoltaic systems use the sun as an energy source. They make electricity without pollutants.

How much solar energy does the sun provide?
The sun sends light and heat. About 10-20% of it reaches Earth. The energy in the Earth's atmosphere is as strong as 1367 W/m².
On Earth, this energy changes. Depending on where you are, the amount varies. For example, it can be between 114 and 268 W/m².
This level of solar energy on Earth is influenced by many factors. This includes the location, altitude and season.
Radiation intensity | Average values (W/m²) |
---|---|
On the surface of the earth | 114-268 |
On the edge of the Earth's atmosphere | 1367 |
How can solar energy be stored?
When the sun is not shining, solar energy can still be used. The secret lies in storage. An electricity storage system makes it possible. It stores the solar power so you can use it at night or on dark days.
With an electricity storage system, the use of solar energy makes even more sense. You can store the electricity that your solar system produces. So you always have enough energy, even when the sun is shining weakly.
An electricity storage system helps you to be less dependent on large energy providers. During the day you produce your own electricity. You can use it in the evening or at night when you need more energy.
There are many different types of electricity storage systems. Some store the electricity in lithium-ion batteries, others in lead-acid batteries. The right choice depends on your budget and needs.
Advantages of solar energy
Solar energy is great. It makes our environment better because it doesn't blow bad stuff into the air. It uses a renewable source that will never run out. This not only protects our planet. It also helps to make energy cheaper. And it makes us less dependent on large energy companies.
Using solar energy is an effective way to reduce our environmental footprint and create a clean and sustainable future.
Emission-free and environmentally friendly
Solar energy is clean. It does not produce dirt that is harmful to us and the environment. In contrast to coal and gas, it helps not to heat up the earth too much.
Sustainable energy source
The sun is always there. Your light and heat cost nothing and will never run out. That makes solar energy a smart long-term choice. It preserves our world for us and makes us less dependent on things that are no longer there at some point.
Reduce energy costs
Making your own electricity saves money. They have to buy less expensive electricity from outside. This keeps more euros in your pocket. Plus, you can even get money back if you have too much electricity. This is particularly worthwhile.
It helps to reduce your energy costs. And it pleases your wallet. Solar energy really pays off, in more ways than one.

The benefits of solar energy are clear. It is good for our world. Even if there are challenges such as costs, it is the best future. With solar energy, we can live cleaner and save money at the same time.
Disadvantages of solar energy
Solar energy has many advantages. But there are also some drawbacks that we shouldn't ignore.
Dependence on weather conditions and daylight
One problem with solar energy is its dependence on weather and sunlight. On cloudy days, energy production is lower. This reduces overall efficiency.
Storage Challenges
Storing the energy is difficult. Batteries in which solar energy can be stored are expensive. Cheap and efficient solutions are still inadequate.
Initial investment costs
To use solar energy, you first need an investment. The costs differ depending on the type of system. Some find this expensive at the beginning, even if it helps to save in the long term.
Location dependency
Not every roof is suitable for solar systems. To work well, the panels need to get a lot of sunlight. Many can therefore not use solar energy, especially in cities or when the roof is not accessible.
However, the advantages of solar energy outweigh the disadvantages. Advances in technology help solve problems. Solar energy thus remains an important, environmentally friendly source of energy.
