1. Co to jest fotowoltaika?
Photovoltaics is a modern technology classified as renewable energy sources (RES). It is used for the active production of electricity through the use of the photovoltaic phenomenon.
2. Z czego składa się zestaw fotowoltaiczny?
The photovoltaic set is used to generate power under the influence of sunlight. For it to work efficiently, many elements are necessary that control its functioning, conversion, distribution and storage of energy generated in the photovoltaic process.
The main components that are constants of the photovoltaic set are:
- DC-AC converter (inverter),
- PV modules,
- wiring and overvoltage protection on both the direct current (DC) and alternating current (AC) sides.
In addition to the above basic elements that may constitute a PV installation, it may include:
- accumulator batteries,
- control and measurement devices,
- battery charge controllers.
3. Czym różnią się kolektory słoneczne od paneli fotowoltaicznych?
Collectors and panels differ in the physical mechanisms on which their operation is based. In the case of collectors that heat water, a liquid coolant, usually glycol, is required, which, as it flows through them, absorbs heat and transfers it to the system. In turn, photovoltaic panels use the “photovoltaic effect” to produce electricity. Solar panels have many names: solar battery, solar cells, solar panels, PV modules.
4. Jak i gdzie można zbudować instalację fotowoltaiczną?
Virtually anywhere there is sunlight. It can be a roof of a building or an unshaded plot of land. A 1kW photovoltaic installation covers an area of approx. 7 m2. In the case of installation on the roof, its angle of inclination should be in the range of 25-60 degrees, and the optimal orientation of the solar panels is the south, possibly south-west, and ultimately south-east. If it is not possible to mount it on the roof, the photovoltaic system can also be installed on the plot or on the facade of the building.
5. Czy mój dom nadaje się do montażu instalacji?
Yes – The photovoltaic installation can be installed both on the roof of the building and on a plot of land on a special construction. The installer will recommend the right size of the installation for you during a free verification visit preceding the purchase decision.
6. Czy instalacja działa także w dni pochmurne?
Yes – because it uses the full spectrum of solar radiation. The installation produces energy on cloudy days thanks to diffused radiation.
7. Czy instalacja fotowoltaiczna działa także zimą?
Yes. The installation works even in winter. The efficiency of the installation may be even higher in a sunny, frosty month than in summer due to the lack of losses related to the heating of the panels.
8.Jak długo działają panele fotowoltaiczne i jaką mają gwarancję?
Parts of photovoltaic panels are subjected to many tests, their production is controlled at every stage. As a result, defective products are rejected very quickly. The result is an extremely low failure rate of the equipment.
When you buy products in our company, you will receive even 12-20 years of warranty for them (for photovoltaic panels) and from 25 to 30 years for their possible power reduction.
9. Czy mogę używać fotowoltaiki do zasilania mojego domu?
Yes. The electricity generated by the photovoltaic installation can be used to power all electrical devices in the home, including lighting, air conditioning, and electronics and household appliances. Today, photovoltaic systems can be easily installed in both traditional and modern homes. The most common practice is to mount the modules on a south-facing roof or wall. There are also solutions that replace roofing materials. Then you can give up tiles, metal sheets or other roofing. Generating one’s own electricity reduces the costs of purchasing electricity from a power utility company and allows for partial or complete independence from the purchase of electricity.
10 Czy mogę używać fotowoltaiki do zasilania mojego biznesu?
Photovoltaic systems can be installed in almost any conceivable structure of commercial buildings. You will find PV systems used for indoor and outdoor lighting, powering air conditioning and cooling systems, powering computer networks as well as powering many other electrical devices.
11. Jak mogę sprawdzić, czy mam wystarczająco dużo światła słonecznego dla PV?
The photovoltaic (PV) system must have direct access to the sun’s rays most of the day. Shading the system can significantly reduce the amount of energy produced. Climate is not a problem as solar PV systems are relatively resistant to harsh weather conditions. In fact, some solar modules perform better on cooler days. Most PV modules are angled to catch as much sunlight as possible, so any snow that accumulates on them usually melts quickly. There is enough sunlight in Poland for solar installations to be useful and effective.
12. Jaka moc systemu jest mi potrzebna?
The power of the photovoltaic system used depends on many factors such as: electricity consumption, type of heating system, roof size and how much you are able to invest. Moreover, do you want the system to meet the total energy requirement or only partially? It is best to contact the designer or system installer to determine what type of system will suit your needs.
13. Dlaczego warto kupić system PV?
14. Jak zaprojektować, zainstalować i utrzymać system PV?
You can make a photovoltaic installation yourself. However, to avoid complications or risks, it is best to hire a professional contractor experienced in installing solar systems. These are quite complex electrical systems, so installation usually requires knowledge and experience as well as specialized measurement equipment and tools. Photovoltaic systems have no moving parts and are therefore maintenance-free. These components are designed to meet strict standards of reliability and durability. Only periodic cleaning of the panels is recommended as the dust on the panels reduces their efficiency.
15. Gdzie mogę znaleźć kogoś, kto zaprojektuje, zainstaluje i utrzyma system fotowoltaiczny?
Our company provides comprehensive investor service, from design to execution and post-warranty service. With the system designer, you can discuss the power requirements, building energy needs, sunlight availability and other important factors to determine the type of system. The system designer will prepare a cost estimate for you and provide you with other relevant information. If the house is not yet designed or built, it is important that the building complies with the requirements of energy-efficient buildings, including as much as possible to reduce the energy demand of your PV system.
16. Jaki jest koszt energii słonecznej, a na ile będę w stanie zaoszczędzić na rachunkach za media?
Unfortunately, there is no one simple answer. But renewable energy subsidies and preferential loans and other incentives will help lower the cost of the solar system. The amount of support depends on a number of factors, such as: whether it is an on-grid or off-grid system, whether it is integrated with the building structure, what is the size of the installation and a specific system manufacturer, seller and installer. In systems for heating hot water and heating buildings, the price of the fuel used must also be taken into account. In most cases, you need to count the cost of natural gas or other fuels and electricity to get a more accurate estimate of what profit to expect. You can ask us to calculate the benefits you will have on an annual basis and compare this figure to your annual electricity needs to see how much you can save.
17. Jakie są wymogi formalne?
Construction works related to the installation of a photovoltaic installation with a capacity of up to 40 kW do not require a building permit. In terms of formalities related to connecting the installation to the power grid, you can count on the support of our experienced Advisors.
18. Jak działa panel fotowoltaiczny?
Photovoltaic panels are mounted on the roof of a building or in another place where they are well exposed to the sun. Photovoltaic cells that are their element convert energy from sunlight into electricity. They are made of semiconductors similar to those of computer processors. At the moment when light falls on the material and is absorbed, the energy of the photons (i.e. coming from the sun) knocks out free electrons from atoms. This allows them to flow freely. The result of this process is the production of electricity. The conversion of light into electricity is known as the photovoltaic process.
19. Przez jaki okres czasu będzie działać instalacja fotowoltaiczna?
When deciding to use and install a photovoltaic installation, we can count on the fact that it will operate for 25-35 years. The warranty you will receive from the manufacturer is:
- 10 years for solar panels,
- 25 years on the power of photovoltaic panels.
20. Ile czasu trwa wykonanie instalacji?
Depending on the size of the building to be equipped with a photovoltaic installation and its complexity, the installation time for installations with a capacity of up to 5 kW is 1 to 2 days.
