Build, assemble and install solar systems yourselfDue to rising energy costs, solar systems are becoming increasingly important. Solar thermal and photovoltaic systems are a technically mature alternative to fossil fuels.
The solar technology is promoted with subsidy programs and low-interest loans state.
Build solar plants yourself
Many homeowners want to build, assemble or install their own solar system to save money. With the necessary knowledge and manual requirements, a self-construction campaign can actually be realized. For solar thermal systems, only the connection to the local power supply network must be carried out by a specialist. Photovoltaic systems equipped with solar collectors are not subject to any legal provisions for construction and installation. As a result, they can be independently designed and put into operation. There are corresponding building instructions in which the installation of solar collectors is shown step by step. Even with a self-built solar system, you can achieve effective results and thus save on ancillary costs.
Function and installation of solar systems
Solar systems are used to generate electricity as well as the heating of water and the heating support. When installing solar technology, it is advisable to follow all steps of the construction manual in the correct order. If any problems or questions arise, it is essential to hire a specialist company. In addition, specialized companies guarantee a proper installation and possible remedy of defects.
Solar systems are preferably mounted facing south on the roof of a building,
to achieve optimal functionality. In the collectors of the system is a heat transfer fluid. This solar fluid is used by
heated by the sun and transported by the controller to the buffer memory. The solar system works in a closed circuit. At the flow and return of the lines breather are installed, can escape through the existing air. An expansion tank ensures the balance of different pressure conditions. If the pressure is too high, solar fluid is released from the circuit, causing the pressure to drop again. Later, the liquid can be pumped back into the circulation of the plant. The fluid of solar systems usually consists of 50 percent water and 50 percent solar fluid. The solar fluid also serves as antifreeze in its capacity.
Installation and commissioning of a solar system for heating support
For the connection of the solar system with the heating and hot water system, a buffer tank with solar heat exchanger is necessary. Before connecting to the heating system, the buffer tank must be completely emptied. After the connection has been made, the buffer tank is filled with water again. It is important to pay constant attention to the density of the solar heat exchanger. Finally, the shut-off valves for the heating circuit are opened and the pressure of the system is restored. Thereafter, the system can be put into operation.
