Welcome to the world of solar energy

Panele fotowoltaicznePhotovoltaics a field of science and technology concerning the processing of sunlight into electricity. Photovoltaics is also one of the most innovative and environmentally friendly technologies. Photovoltaic systems are characterized by simplicity of installation and are easy to use both in industry and in households.

In the Enis offer you can find photovoltaic panels, inverters and accessories required for installation of photovoltaic systems. 

Our experts will introduce the issues related to the practical application of photovoltaic technology and will help raise funding for investment.

Insolation in Poland

The average annual insolation in Poland is about 1000 kWh/m2.

Distribution of solar radiation is uneven annually. Approximately 80% of annual sunlight falls on the spring-summer period. (April-September) Moreover, in each region there are periodic changes in insolation due to weather conditions, cloud cover or air pollution (eg industry). In Poland, the annual average amount of sunshine is 1600 hours.

Intermediate systems

Intermediate systems use steam to produce electricity from the sun, in a similar manner to conventional steam power plants. The main difference is that the concentrated solar power (CSP) to generate heat, use carbon-free, clean sunlight instead of the fossil fuels and nuclear energy.

In intermediate systems solar radiation is concentrated by parabolic shaped mirrors. These mirrors, arranged in rows, are more than 400 meters long and are made of parabolic mirror segments that ensure maximum use of sunlight daily.

 

 

Basic elements of the intermediate is shown in the figure:

1. Parabolic mirrors
2. Receiver tubes
3. Oil transporting heat
4, 6. Heat exchanger
5. Storage tanks
7. Steam
8. Turbine
9. Generator
10. Condenser
11. Cooling Tower.

The principle of operation of the intermediate system is as follows: under direct sunlight of a solar plant, parabolic mirrors, arranged in rows concentrate solar radiation. Parabolic shape of the mirror provides the highest efficiency of the system, because it allows the sun tracking, so that mirrors store solar radiation on a continuous basis throughout the day. Radiation is stored on specially coated vacuum receiving tubes, that convert it into heat. Then, heat is transferred by means of a special oil, which receiving tube are filled with. Oil circulating in the system is heated to a temperature of 400 ° C, through a heat exchanger the oil heats the steam, which in turn feeds the traditional steam turbines.

A key element of intermediate systems is receiving tube, which has a decisive impact on the overall performance and power efficiency. It is characterized by a high degree of absorption of solar energy, as well as low emission of thermal energy (heat emission).

The highest optical and absorption properties of receiving tubes are ensured by a special absorption coatings with their long-term thermal stability. This contributes to a significant reduction of the cost of electricity and to production maximization.

The use of concentrated solar power plant is the most desirable in the large scale solutions with capacities of up to 300 MW. The most appropriate location for this type of plant are large dry and uncultivated areas, which makes getting the land relatively cheap. Climatic conditions in Poland are not conducive to investments in intermediate solar power systems.

Financial Consulting - Grants and Loans

Energy security achieved inter alia through the diversification of energy sources in the direction of renewable energy is currently one of the main objectives of the national policy. All documents, in particular environmental programs ranging from national to municipal level ending, appeal to those issues.

Due to the importance and significance of this area, you can find possibilities of multi – directional co-financing with national and EU sources, of the investments involving the use of renewable energy sources.

    panele fotowoltaiczne polikrystaliczne POLYCRYSTALLINE SOLAR PANELS

    Polycrystalline panels are made of silicon cells. Polycrystalline panels are made up of cells, which are a combination of multiple small silicon crystals. This is the reason, why their surface is not homogeneous, thus, they are slightly less efficient and simultaneously, less expensive.
    Thanks to those characteristics of polycrystalline panels, they are commonly used in residential buildings and in large solar power plants.

    panele fotowoltaiczne monokrystaliczne MONOCRYSTALLINE SOLAR PANELS

    Monocrystalline panels are composed of individual cells that are formed of a homogeneous silicon crystal with systematic internal structure. They are formed by cutting the silicon block of appropriate size, for layers thick of about 0.3 mm.

    Panel produced this way has the highest level of efficiency and service life.
