Due to the various changes in the world and rising prices, having your own solar system is becoming more important than ever. It enables solar energy to be fed into the domestic electricity or heat circuit. This happens when the sun shines on the solar panels, generating electricity in the case of photovoltaic systems or heat in the case of solar thermal systems.
The resulting energy is then used to generate hot water or to keep the light on. Although this one-time purchase is not exactly cheap, it is very worthwhile in the long run.
1. Hot water and solar energy
Solar thermal systems can supply the heat to the service water supply and/or the heating system, which enables long-term savings and can make a large part of the other heating costs disappear.
Tip: If you want to take care of your own water supply conscientiously, you should an analysis of the domestic water consider. Water pipes and geological changes in where you live can introduce heavy metals and other pollutants into the water.
- A water test only requires a sample of the water to be analyzed.
- This is then sent to a lab…
- … and the test results are available within a few days.
Ready-to-use test kits are available so that anyone can carry out the analysis. Detailed instructions are also included. So one is worth it Solar thermal in your own house best for hot water.

1.1. sustainable living
Photovoltaic systems enable sustainable living because they do not require any fossil fuels and do not release any fine dust such as soot particles. Also, these systems only require a one-off, larger expenditure and they can then be used for decades.
Whether these are suitable for a house, a terraced house or even an apartment building depends on the size. Generally you can solar cells can also be set up on straight roofs, which means that no space is lost around the building. So the advantages outweigh the disadvantages.
2. Energy saving measures
So while the electricity from the socket, which comes from the local large corporation, can increasingly be dispensed with and the prices remain manageable, the electricity itself does not have to be dispensed with. This enables a solar system to have many advantages.
In the context of Renovation and modernization measures solar panels can be attached to the building. It is even possible to bring unused energy into the public power grid and receive money for it.
Although this option is not yet available everywhere, it is precisely in times of crisis that things continue to develop that previously took many years. After all, no one wants to be without a warm shower, an evening of TV or the Internet.
3. Hydroelectric power
For some real estate owners there is even the possibility, in addition to a solar system to rely on hydropower. Older houses in particular, which are located on a small river or stream, have water wheels. Not only did these exist in the past, they can still be used today. There is also the possibility for some houses to acquire water usage rights and retrofit a water energy system.
The advantage of water is that nothing in the world works without water. Where people have built houses, the water can also pave its way again. It is finally the strongest force on earth that is. So why not use what almost suggests itself?
3.1. Conclusion
No life without water. However, if you want to know the quality of your water, you should do a water test. This is easy to carry out and can be worthwhile, especially if you want to provide hot water in your own house or if you rely on hydropower.
