We have collected the most important issues in one place so that each of you can quickly educate yourself on the subject of photovoltaics.
Many of the concepts of photovoltaics are not very clear, especially at the beginning of the adventure in this industry. We keep updating the concepts collected on this page. With this FAQ, users can find information more easily without having to contact customer service or search other sources of information, which usually speeds up problem resolution and improves the quality of service.
The cost of a photovoltaic installation depends on many factors, such as the size of the system, the type of photovoltaic panels, the efficiency of the inverter, the type of installation, the availability of subsidies or tax credits, and the cost of installation and maintenance.
The cost of a photovoltaic installation can range from several thousand to tens of thousands of zlotys, depending on the above factors. However, due to the growing solar market, the price of photovoltaic panels is steadily falling, making the cost of installation increasingly affordable as well.
It is also worth remembering that the cost of a photovoltaic installation can be recouped within a few years through savings on electricity bills and through the availability of subsidies or tax credits that reduce the cost of the investment.
The payback time of a photovoltaic system depends on a number of factors, such as the cost of the installation, the size of the system, the efficiency of the photovoltaic panels, the return on investment (ROI) and the electricity rate.
In Poland, for a typical photovoltaic installation, the payback time is usually 5 to 10 years. After this period, owners of photovoltaic systems begin to save on their electricity bills, as they use the energy generated by their photovoltaic panels instead of buying power from the electricity grid.
Investing in photovoltaics can be profitable for people who want to lower their electricity bills, increase their energy independence or improve their contribution to environmental protection. This investment can be particularly attractive for those living in single-family homes or running businesses that consume large amounts of electricity.
The return on investment in photovoltaics depends on a number of factors, such as the cost of installation, the size of the system, the efficiency of the photovoltaic panels, the return on investment (ROI) and the electricity rate.
RES stands for “renewable energy sources” or “renewable energy.” These are types of energy from natural sources that are unlimited or renewable in the short term and do not cause harm to the environment. Renewable energy sources include such energy sources as solar energy, wind energy, hydropower, geothermal energy, biomass energy and biogas energy.
Renewable energy is increasingly popular due to its positive impact on the environment and the rising prices of traditional energy sources. The use of renewable energy also has a positive impact on the country’s energy independence and reduced dependence on fossil fuel imports.
In Poland, RES development is promoted by the government by providing subsidies, tax breaks and other incentives to investors. Renewable energy sources are playing an increasingly important role in the Polish energy sector and contributing to sustainable economic development.
Photovoltaics is a technology that allows the conversion of solar energy into electricity rather than direct heating. However, there are ways to use the electricity generated by photovoltaic panels to heat your home.
One solution is to use a heat pump system, which uses electricity to draw heat from the air, water or earth, and then transfers the heat to the rooms. Another solution is to use water heaters or electric-powered heating panels.
Yes, in Poland there are various types of subsidies and support programs for people who want to invest in a photovoltaic installation.
The “My Current” program is one of the most popular subsidies in Poland. This is a subsidy program that allows you to receive up to 50% of the eligible costs of a photovoltaic installation. The program targets single-family homeowners and micro and small businesses.
Another program is the “Clean Air” program, which is aimed at owners of single-family houses and consists in subsidizing the cost of thermal modernization of buildings and replacing heat sources with cleaner ones.
There are also other support programs, such as the Cohesion Fund, regional funds or programs offered by banks and electricity suppliers. It is worth turning to a specialist in the field. Renewable energy or to the local renewable energy office. Renewable Energy for more information on available support programs and subsidies in your area.
Selecting the right photovoltaic panels depends on many factors, including:
When choosing panels, it is also worth paying attention to installation issues, such as the proper positioning of the panels on the roof, selection of the inverter, wiring and mounting system.
A good solution is to consult an experienced photovoltaic specialist who will help select the right panels and the entire system according to individual needs and local conditions.
The installation time of photovoltaic panels is calculated based on many factors, such as the number of panels to be installed, the size of the entire system, the location and type of installation, and the availability of materials.
Installation of a standard photovoltaic system on the roof of a house usually takes one to three working days. However, this time may increase if the installation requires special adjustments to the roof or other difficult installation conditions.
Installation of large photovoltaic systems, for example, on land, can take several weeks or even months. In this case, installation time depends on a number of factors, including the number of panels, system size, availability of human resources and equipment, field conditions, etc.
In any case, it is best to consult an experienced installer who will be able to estimate the installation time based on specific conditions.
The most common faults in a photovoltaic installation can include:
1. damaged photovoltaic panels: we are talking about mechanical damage, cracks or splintering, and problems with electrical connections that can lead to a drop in panel performance.
2 Defective inverters: An inverter is a device that converts the direct current produced by photovoltaic panels into alternating current that can be used at home or sent to the grid. Failure of the inverter can lead to interruption of the flow of energy and complete lack of electricity.
3 Electrical connection problems: Connections between photovoltaic panels, the inverter, batteries and the electrical grid can become damaged, leading to failure of the entire system.
4 Battery problems: If the photovoltaic system is equipped with an energy storage system, faults related to batteries can affect the entire system. There may be problems with charge level, performance or battery life.
5 Weather damage: Extreme weather conditions such as hail, windstorms, floods or icing can damage photovoltaic panels, inverters or electrical connections.
To avoid these problems, it is important to have your photovoltaic system regularly inspected and maintained by an experienced installer or service technician, and to use high-quality components and security systems.
