Electricity prices continue to climb. But there is a way to counteract this: the installation of a photovoltaic system. But that's not their only advantage.

PV systems already offer many households in Germany the possibility of independent, cheap and clean power generation. But many homeowners are confused by the abundance of conflicting information about solar systems. So how do you know if a solar system is right for you? We clarify whether and when a photovoltaic system is worthwhile in 2021.

5 advantages of a photovoltaic system

Stubborn photovoltaic errors continue to cause uncertainty when it comes to solar energy. We present 5 clear advantages of a photovoltaic system to counteract the persistent stereotypes about solar energy.

1. Decreasing acquisition costs with increasing quality Solar systems are expensive? This photovoltaic error is widespread. High time to get rid of him. The acquisition costs for photovoltaic systems have fallen by more than 75 percent since 2006, with constantly increasing quality and performance requirements. In addition, many homeowners can benefit from various government subsidies when purchasing a PV system. The purchase of a PV system is currently more profitable than ever.

2. Solar power is cheap Falling costs for the purchase of a photovoltaic system, but rising electricity costs from the energy supplier: In the last 20 years, the electricity price in Germany has risen from an average of 13.94 cents per kilowatt hour to 31.89 cents per kilowatt hour. Currently, the production costs of your self-produced solar power - depending on the size of your PV system - are only 8 to 12 cents per kilowatt hour. Your financial savings increase with every kilowatt hour of solar power used - especially if you have a high level of self-consumption and use the power from your PV system yourself. So it's crystal clear that solar power is the right choice if your focus is on the lowest possible electricity costs.

3. Long service life of photovoltaic systems Photovoltaic systems are durable. After installing your solar system, you can generally generate your own electricity for up to 25 years, easily and inexpensively. As a rule, solar modules even work effectively longer than the product guarantee given by the manufacturer promises. It is therefore worth considering the photovoltaic system during the planning of a renovation or new construction, even if the installation does not take place immediately.

4. Flexibility through power storage Power storage makes it possible to temporarily store the generated solar power when you do not need it. The electricity generated by your system throughout the day is stored in storage and can be used when you need it. With your PV system, you are independent of the weather and use clean electricity even when the sun is not shining.

5. Solar power is environmentally friendly and emission-free The most important thing at the end: With a solar system you protect the climate. You generate your own, inexpensive and clean electricity. And all without noise, smell or pollutants. The energetic amortization period for a solar system in Germany is currently around 1.3 years. This means that a PV system can still generate pure renewable energy for around 20 to 25 years after this time.

When is a photovoltaic system worthwhile?

One hears from many quarters that solar systems are no longer worthwhile. But far from it - nothing is currently more worthwhile than the purchase of a photovoltaic system. Factors such as the orientation of the roof or where you live hardly play a role anymore. Solar energy is worth it - on every roof and in every region of Germany.

The installation of a PV system is particularly worthwhile if you have a high personal requirement and consume the electricity generated yourself. The days when you could achieve a high return through full feed-in are long gone. Your PV system now pays for itself based on the level of your own consumption. The higher your self-consumption, the higher the return. With the currently manageable prices for solar modules, it makes sense to cover the roof with them as much as possible. Because one thing is clear: the more electricity you can generate with your system, the more independent you are from the power grid and the more clean electricity you generate. What if you can generate more electricity than you use during the day? You can easily use excess electricity generated at a later point in time with the help of an electricity storage system. These are often subsidized by the state and enable you to use even more for yourself. You receive the feed-in tariff for the electricity that is then still left over. Since this is constantly falling, however, it is worth installing an electricity storage system.

Of course, you increase the self-consumption of your PV system in particular if you charge your electric car using your solar system - or want to charge it in the future. A wall box can easily be integrated into your PV project. Because for many e-car owners and prospects, the cost and environmental factor play an important role when considering whether the purchase of a solar system is worthwhile for them.

For many, the purchase of a photovoltaic system is associated with a large investment. Especially when planning or renovating your home, large investments like this need to be well thought out. We briefly summarize the financial factors for you and check how profitable PV systems are today.

Purchase and operation of a PV system:

Financial benefits of a PV system:

It is true that the purchase of a PV system is no longer worthwhile for pure feed-in due to the constantly falling feed-in tariff. A combination of self-consumption and feed-in tariffs is usually the right way. Thanks to the rapid amortization period, you can achieve considerable financial gains over the remaining life of the system. How quickly your PV system pays for itself depends on many different factors such as the size, orientation and use of the system. In particular, it also depends on whether you integrate an electricity storage system or not. As an example, we consider a 4-person household with a 10 kWp system - with and without an optional 10kWh battery:

Are you deterred by the high acquisition costs despite the many advantages of a solar system? Rental options are now also available as an alternative to purchasing a complete PV system. There is a suitable photovoltaic solution for every private household. It is clear that the self-generated electricity is in any case significantly cheaper than that from the energy supplier.

Conclusion

A photovoltaic system is a big investment, of course. However, a photovoltaic system is now more worthwhile than ever, especially due to the sharp drop in procurement costs and the rising electricity prices of the network providers. And that regardless of where you live.

In general:

With the help of your self-generated solar energy, you can easily increase your degree of self-sufficiency and save money at the same time. Request a non-binding offer from zolar today and start into your sunny future.
