Advantage of solar systems

An important advantage of solar systems at today’s level of development of solar technology lies in the fact that there is no longer a big problem to integrate solar systems with other conventional heating systems for the most optimal way of implementing these systems, which is a very important fact for investors and users. The best effect of using solar energy for solar heating of residential buildings and commercial buildings can be realized in transitional periods. Due to the variability of the power of the sun’s radiation during the day, month and year, it is not possible to perform the installation of solar heating, and at the same time it would be economically profitable, which would enable the complete heating of the space of a residential building or other business object during the entire winter period. Therefore, solar heating systems must be combined with some other energy sources that use some conventional form of energy.

Investment in a solar system, unlike investments in equipment for conventional fuels, is paid back in a few years, and the rest of the time until the lifetime of the solar equipment, which is a period of 20 to 30 years, the owner has free energy. Most often, the payback periods for residential buildings or other buildings of similar square footage range from 5 to 10 years, which is constantly decreasing, taking into account the constant increase in the price of primary energy sources and the decrease in the price of solar equipment.

The recent increase in the production of photovoltaic solar panels, along with a drop in price, opens up a large number of new markets for a wide variety of applications, such as telecommunications, lighting, street or surrounding lighting for residential buildings and commercial buildings, providing energy for entire settlements, etc. All these and other applications have proven to be very competitive and cost-effective compared to existing technologies.

Application of photovoltaic systems

Application of photovoltaic systems is now possible in various parts of buildings. In the long term, this way of thinking and designing will be unavoidable. The long-term potential of photovoltaic systems in the building sector is still underestimated. Designing buildings as energy producers with modules integrated into the facade and roofs enriches the vision of a city that supplies itself without harmful effects. Successful foreign examples prove to us that it is possible to turn this vision into established practice to a large extent. The use of photovoltaic systems can significantly reduce the consumption of electricity from power plants. They can be installed in any building structure, from residential buildings, bus stations to large office buildings. Although an accurate forecast of photovoltaic performance requires a careful analysis of factors such as the amount of solar radiation falling on the building, the orientation of the building, the electrical stability of the electrical distribution network, etc., it can be easily concluded that this technology has great potential. Photovoltaic systems are modular so their power can be designed for virtually any purpose.
As buildings are the only resource that is constantly increasing, there is a need for their rationalization in terms of electricity consumption, which is why developed countries in the world invest large amounts of money in the research of solar energy conversion systems, which will best respond to the challenges that are required of it. . The development of photovoltaic systems led to the production of panels of various shapes, colors, transparency, energy characteristics, etc. Today, solar cells are also produced on flexible foils, which increases their visibility on buildings or other objects. This enables greater freedom of architectural expression when designing energy-efficient buildings.

Photovoltaic systems as a substitute

Photovoltaic systems are used as a substitute for conventional building materials in parts of the building envelope. They are generally built as an integral part of the facade and roof structure of new buildings. The increase in requirements regarding the properties of facades has led to the fact that envelopes must be more complex and multifunctional elements of the building. Modern technological development allows radical changes in the design of the facade or roof. In order to achieve good performance of a residential building or business building, photovoltaic panels should not only produce energy, but should also satisfy a number of other criteria. The systems used today in the building envelope must provide thermal and waterproofing, protection from the sun, noise and light, as well as safety.
