The introduction of innovative technology has made it possible to use alternative sources of energy. Today, many people are inclined to install devices for which the energy source is solar energy. The introduction of innovative technologies has made it possible to use alternative energy sources to generate electricity. Many people are currently tempted to install devices that use solar energy as their energy source. Solar panels on the roof are a complex of interconnected individual photovoltaic cells, which provide a calculated power. So, let’s find out the top four benefits of installing solar panels on your home.
Different Types of Solar Panels on The Roof of a Private House
- Today, modules based on the properties of silicon semiconductors are better known. Polycrystalline cell-based devices are the most popular. They have the right balance between the amount of power they generate and their cost. These systems are easy to install and do not require any special skills. Externally, they are characterized by their blue coloring and the crystalline structure of the constituent elements.
- Monocrystalline panels are more efficient than polycrystalline panels. However, an important fact should not be overlooked: the cost of installing solar panels on the roof in this case is significantly higher. The filling elements of the modules have a polygonal shape.
- Solar panels on the roof, containing amorphous silicon, are the least efficient option, although this does not particularly affect the demand for products. This is due to the cheapness of the energy generated.
Two Other Varieties of Solar Modules Are Worth Mentioning
Cadmium telluride solar systems are low power. They are made using film technology: hundreds of thousands of micrometers of semiconductors are deposited in a thin layer on the film. Another type of panel is the flexible CIGS battery, which is more efficient than the previous type.
So, What Are the Benefits of Installing Solar Panels on The Roof of The House?
As a rule, the first advantages of solar systems are as follows:
- A fairly long service life, with the performance characteristics of the panels not changing;
- such equipment rarely causes problems, we can say that they do not require maintenance
- installation of an alternative source gives significant financial savings because electricity and gas costs are reduced;
- the modules are easy to use.
How to Choose the Right Off-Grid System
Before purchasing a solar power system, consider the following parameters:
- The daily consumption of the electrical appliances to be connected.
- Place of installation of the solar panels (orientation to the south, optimum angle of inclination, no shadow on the panels).
- Location of the batteries (must be located indoors at plus temperature, but no higher than 25 degrees).
- Peak loads of electrical appliances (pumps, refrigerator).
- Year-round or summer-only operation of the system.
Monocrystalline is used more often in regions with high solar activity, polycrystalline in regions with low solar activity. If you need a solar panel for your summer cottage, check out the micromorphic models. They are inexpensive but have twice the surface area. Micromorphic silicon systems can operate effectively at a wide-angle and in cloudy weather.
Selection Guidelines
What factors must be taken into consideration when deciding to use solar energy for your home?
The average amount of energy per m2 per year. To make sure you get the right panels for the job, you must first consider the insolation level in your area. In simple terms, determine how much solar energy is transmitted per 1 m2/year on average. Based on this, calculate how many solar panels you need on your rooftop;
In principle, you should know that all solar installations are able to provide the same output, the only difference being that the more efficient ones require less space. For example, to generate 1kW of electricity you would need 8 square meters of monocrystalline batteries or 20 square meters of amorphous silicon film panels.
Solar Panel Installation
It is possible to install the panels either directly on the roof or on a supporting structure specially designed for that purpose. In the first case, the panels will be placed at a fixed angle, which will create certain difficulties in their operation, for example, during periods of low intensity of the sun. Thus, the only acceptable type of panels will remain those that are not dependent on the activity of the sun.
The second method is used more frequently, especially since it can be applied to any roof. Supporting structure in addition to what gives resistance to weather conditions, such as strong gusts of wind, provides the ability to adjust the angle of inclination. The roof of a house may be of any configuration, except for pitched roofs with a slope of more than 40°.
- If the roof slope for solar panels does not exceed 40°, then the installation is carried out either with or without a frame structure.
- On flat roofs, the installation is carried out on an inclined plane with a special metal frame.
- It is very rare for such radiators to be installed on a wall. As in the previous case, the installation is carried out on frame construction, necessarily with a slope.
- Solar systems in flats are usually installed either on the roof of the balcony or loggia or on the outer side.
Useful Information
Although solar panels on the roof of the apartment building will be more expensive in total cost than individual panels, they reduce maintenance costs. It should not be forgotten that there are no blackouts on the roofs of high-rise buildings, which means that the modules on them will work with a higher capacity.
Conclusion
Installation on the ground is carried out on a special support structure located no lower than half a meter from the ground. This option is recommended in particular for regions with heavy snowfall. A solar panel is a device that collects light energy from the sun and converts it into an electric current. It is based on photovoltaic cells – semiconductor photovoltaic converters.
