The question of the so-called green tariff currently sounds almost every corner. With the jumps in the price of electricity, we have to adjust and save. If you combine economy with the search for an alternative source of energy, success is guaranteed. The autonomous power supply of a house on solar panels just a decade ago seemed fantastic or something very expensive. Currently, in cities, there are always cars-representatives of companies involved in installing a solar panel on the roof of the house. Whether this is beneficial, and what you need to know before applying to such firms, we will consider below.
Solar panels for heating the house
As a rule, it is the issue of heating that excites us most of all, it also becomes an associate to the search for alternative energy. But even in this age of high technology we have to count everything, because the possibilities of technology are not unlimited. Therefore, immediately remove the pink glasses and get acquainted with the facts that manufacturers prefer not to advertise:
- really the system works only in those areas where there are enough sunny days throughout the year (in winter, efficiency does not decrease on a sunny day);
- Even long before the central or gas heating is turned off, the house needs to be properly insulated.
Now with regard directly to the use of solar panels for heating the house, more precisely the rational choice of the system. For obvious reasons, a certain part of the generated energy will be allocated for heating. As a result, the lower the heating temperature (without compromising comfort), the more efficient the operation of the entire system.
From this point of view, you are free to choose between panels and warm floors . This panel is considered the most preferable solution, because they also protect the walls of the house from dampness. You can heat the floor, this is also a large area, and it does not necessarily have to warm it to get a comfortable home environment.
Solar power stations for home
Now let's return to the question of installing the entire system. You are free to choose your option: calculate and purchase all components separately for self-assembly, or buy a ready-made solution. It is necessary to understand that solar-powered power stations for the house in ready-made form are always more expensive, but this is already a completely competent and balanced solution.
Solar panels for the house will be chosen based on the main parameters and characteristics of the system:
- First of all, you need to know the power consumption in the house. In addition to lighting on solar panels, we need to provide for the home work of basic household appliances. As a rule, the technology does not consume more than 3 kW, almost always 2-2.5 kW. Therefore, this maximum is quite acceptable to take as the output power of the system.
- Under the general name of "batteries for home" manufacturers offer three types of panels: polycrystalline, monocrystalline and film. The latter option has not found application, as it gradually loses its power, and it is difficult to call such a solution durable. For regions with constant or frequent cloudiness, solar polycrystalline batteries on the roof of a private house are more suitable.
- We pay special attention to the controller. While your batteries are running, and there is no energy consumption, everything accumulates in special containers. When several devices consume energy, it needs to be distributed between them. And sometimes you have to take the missing energy of their tanks. All this monotonous work is done by the controller. For obvious reasons, its quality and durability is not the last.
