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
The main components that are constituents 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 can constitute a PV installation, it may include:
- accumulator batteries,
- control and measurement devices,
- battery charge controllers.
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.
Virtually anywhere there is sunlight. It can be a roof of a building as well as 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.
Yes – The photovoltaic installation can be installed both on the roof of the building and on a plot 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.
Yes – because it uses the full spectrum of solar radiation. The installation produces energy on cloudy days thanks to diffused radiation.
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.
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.
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 own electricity reduces the costs of purchasing electricity from a power utility and allows for partial or complete independence from the purchase of electricity.
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 refrigeration systems, powering computer networks as well as powering many other electrical devices.
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 PV 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.
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. In addition, 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.
People decide to buy solar systems for a variety of reasons. For example, some people buy solar systems to conserve fossil fuel resources and to reduce air pollution. Others prefer to invest in order to pay less for electricity. Some people need independence or energy security to protect themselves against future increases in electricity prices.
If the system is designed correctly, it may be able to provide power in the event of a utility power outage, thereby increasing the reliability of the power supply. Some live in places where the cost of expanding power lines is higher than buying a solar system.
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 settling on the panels reduces their efficiency.
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 meets the requirements of energy-efficient buildings, including as much as possible to reduce the energy demand of your PV system.
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 the 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.
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.
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.
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.
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.
