The sun is the largest source of energy on earth. It provides us with heat and light and is therefore simply essential for life. The sun is also a large energy reservoir that we could use to generate electricity and heat. No fossil fuels, lower electricity bills and producing your own electricity sustainably and independently – sounds great, right? That's exactly what we promisethe alternative energy sourceswhich are not only super efficient, but also significantly cheaper than before. Would you also like to have a solar system on your own roof, but are afraid of the high purchase costs? What are the most important advantages of solar systems and who is photovoltaics worthwhile for? We'll explain all of this to you below!
How does photovoltaics work?
Obtaining energy from the sun is thanksmodern solar systemseasier than ever before. Photovoltaic systems promise clean and cheap electricity from your own production and are significantly more environmentally friendly. In contrast to fossil energy sources such as oil and coal, solar energy is inexhaustible and is therefore one of the renewable energies. We all now know that large power plants release environmentally harmful substances. A solar system, on the other hand, is an excellent way to significantly reduce our ecological footprint and do something good for nature. So if you want to live more sustainably, investing in a modern solar system is definitely worth it.
In times when fossil fuel resources are slowly being exhausted, investing in a modern solar system is only logical. A photovoltaic system is actually witchcraft - it converts sunlight into electricity. It consists of solar modules that are installed on the roof or terrace. The solar cells it contains absorb sunlight and convert it into electricity via an inverter.
Solar systems advantages: No more high electricity bills
Have you been annoyed about your already high electricity bills for years? Then there would bemodern solar systemsthe right solution for you! As your own energy producer, with a solar system you gain independence from all electricity providers and are also less susceptible to power outages. The purchase costs are high, but you are protected from the ever-increasing electricity prices on a one-off basis and in the long term. In addition, solar energy is basically free and inexhaustible and the photovoltaic systems are safe and free of pollutants. Without a solar system, we buy a kilowatt hour of electricity from the grid for around 30 cents. However, we produce our own solar power for around 10-13 cents per kilowatt hour - less than half that.
How much can you supply yourself with solar power?
Whether it is worth purchasing a solar system depends largely on the individual situation and our needs. Since the sun doesn't shine around the clock, many homeowners wonder whether they can cover all of their needs with it. Especially in the midday hours, the systems generate more electricity than we possibly use. However, if the system supplies less electricity than you need, you will still have to draw it from the public grid at the usual prices. In order to optimize your own consumption, you should pay attention to the correct alignment of the solar systems when planning. While a south-facing system can achieve maximum yields, a system with an east-west orientation is aimed at increased electricity production in the morning and evening hours.
Would you rather use solar power yourself or feed it into the system?
If youabout the solar system advantagesIf you are thinking about it and are not sure whether the purchase is worth it, you should first know what should happen with the electricity generated. Solar energy from your own roof makes sense especially if you use the majority of the energy produced yourself. If the system generates more electricity than you need, you can either feed it into the public power grid for a fee or store it in a solar power storage system and use it later. With the feed-in tariff you can fully refinance the purchase price of the system after a few years and even generate profits. However, the remuneration continues to fall and is currently around 7 cents per kilowatt hour. Selling electricity is therefore less worthwhile than using it yourself. In order to keep electricity costs low and to be able to use the solar power generated at a later date, it is better to invest in solar storage in the form of batteries instead.
