Investors are increasingly seeking eco-friendly solutions for their homes. Solar power for homes not only benefits the environment but also offers economic advantages. Such an investment can quickly pay off for the investor. Nevertheless, this issue still raises many questions among investors. Which solar panels should one choose? Where should solar installations be placed to maximize their efficiency? These are just some of the questions that arise from their side.
Although the photovoltaic effect was discovered in the late 19th century, it has only been boldly utilized recently. Solar power for homes allows for a significant reduction in energy costs, and more and more people are deciding to adopt this solution. Moreover, solar panels, by harnessing alternative energy sources, allow us to take care of our planet. How does the process of energy generation through solar panels work? Cells placed in the installation draw electricity from sunlight, which is then delivered to the house through a created structure. The electricity must reach the inverter and then, thanks to appropriate wiring, it powers specific electrical devices.
Solar power for single-family homes is constantly evolving. New and more exciting solutions and proposals are emerging. Even the appearance of the panels is changing – the market offers increasingly delicate and aesthetically pleasing designs. Solar power for single-family homes is an idea that interests an increasing number of people. Electricity costs are rising, and there is no sign of their decrease. The opportunity to obtain electricity from alternative sources is an ideal solution given this perspective.
The average power of a solar panel is around 250 Watts, and its size ranges from 1 to 1.8 square meters. A well-functioning solar power system for a home will require the use of several panels. The exact number of panels needed depends on the specific energy needs of the single-family home. Before making a choice, specialized calculations should be conducted to determine the average energy consumption of the building. Thanks to these calculations, it will be easier to select the appropriate power of the solar panel. It is assumed that an average family (parents and two children living in a single-family home) consumes annually between 1900 kWh to 2500 kWh.
Solar power for single-family homes comes in various types, each with its proponents. Two basic divisions of solar panels are distinguished – monocrystalline and polycrystalline. These are the most commonly chosen products for this type of energy supply, although there are also panels with amorphous, CdTe, or CIGS cells.
Monocrystalline Panels
This type of solar installation is a relatively expensive solution, but it comes with high quality. Monocrystalline solar panels have cells made from a large silicon crystal, which gives them a deep, dark color. Moreover, the use of silicon contributes to high-class installation efficiency. Solar power systems for homes are more durable at very high temperatures and work better in weaker sunlight compared to polycrystalline solar panels. Unfortunately, using an entire silicon crystal restricts the ability to freely modify the shape of the cells. They have rounded edges. As a result, monocrystalline solar panels make it difficult to evenly cover the entire roof with the installation.
Polycrystalline Panels
This type of solar power for homes emerged slightly later than monocrystalline panels. Despite being modeled after their predecessor, this solar installation has several differences. It's essential to focus on the construction itself. Polycrystalline solar panels do not have cells made from an entire crystal but are in the form of crystallized silicon. Thanks to this design, the shape of the installation can be freely adjusted to the surface's needs. As a result, instead of panels with rounded finishes, rectangular panels are produced. Such solar panels can cover the entire roof's surface! However, they have lower power than their predecessors. Therefore, a larger surface area is required to generate the same amount of electricity. Polycrystalline solar panels have lower efficiency but are also less expensive.
So, which solar power solution for single-family homes is better? It primarily depends on your needs. If you value high energy efficiency, monocrystalline panels are definitely the better choice. On the other hand, if you prioritize affordability, polycrystalline panels would be a better fit.
Investors are increasingly seeking ecological solutions for their homes. Solar panels for home not only contribute to ecology but also to economy. Such an investment can quickly pay off for the investor. Nevertheless, this issue still raises many questions among investors. What solar panels should be chosen? Where to place the solar installations to make them most efficient? These are just some of the questions they ask.
Although the photovoltaic effect was discovered in the late 19th century, it is only recently that it has been boldly utilized. Solar panels for home allow for significant reduction in energy costs, and more and more people are deciding to use them. Moreover, solar panels, thanks to the utilization of alternative energy sources, allow us to take care of our planet. How does the process of energy collection by solar panels work? The cells placed in the installation collect current from sunlight, which is then delivered to the home through the created structure. The current must reach the inverter and then, thanks to appropriate wiring, to specific electrical devices.
Solar panels for single-family homes are continuously developing. New and more interesting solutions and proposals are emerging. Even the appearance of the panels is changing - there are increasingly delicate and aesthetically pleasing solutions available on the market. Solar panels for single-family homes are an idea that interests an increasing number of people. Electricity costs are rising, and it seems that there is no end in sight. The possibility of obtaining electricity from alternative sources is an ideal solution in this regard.
The power of an average solar panel is around 250 watts, and its size ranges from 1 to 1.8 square meters. Well-functioning solar panels for home will require the use of several panels. The exact number of panels needed depends on the energy demand of a particular single-family home.

It is assumed that an average family (parents and two children living in a single-family home) consumes annually from 1900 kWh to 2500 kWh.
Solar panels for single-family homes come in various types, and each of them has its supporters. There are two main divisions when it comes to solar panels - monocrystalline and polycrystalline. These are the most commonly chosen products for this type of energy supply, although there are also panels with amorphous, CdTe, or CIGS cells.
Monocrystalline Panels
This photovoltaic installation is a relatively expensive solution, but it comes with high quality. Monocrystalline solar panels have cells made from a large silicon crystal, which gives them a deep, dark color. Moreover, the use of silicon contributes to the high efficiency of the installation. Solar panels for home are more durable at very high temperatures and perform better than polycrystalline solar panels in low sunlight conditions. Unfortunately, utilizing the entire silicon crystal means that the shape of the cells cannot be freely modified. They have rounded edges. As a result, monocrystalline solar panels cannot provide uniform coverage of the entire roof with the installation.
Polycrystalline Panels
This type of solar panels for home was developed a bit later than monocrystalline panels. Despite being inspired by the predecessor, this photovoltaic installation has several differences. First and foremost, let's take a closer look at the construction itself. Polycrystalline solar panels do not have cells made from a complete crystal but are in the form of crystallized silicon. This allows for the installation to be freely adjusted to the surface's needs, resulting in rectangular panels instead of panels with rounded finishes. Such solar panels can cover the entire roof surface! However, they have lower power output compared to their predecessors. Therefore, a larger surface area is required to generate the same amount of electricity. Polycrystalline solar panels have lower efficiency but are also more affordable.
So which solar panels for single-family homes will be better? It primarily depends on your needs. If you value high energy efficiency, monocrystalline panels will be the better choice. On the other hand, if you prefer a more budget-friendly option, it's better to go with polycrystalline panels.
Once the solar panels have been chosen, you also need to decide on their placement. In this case, the most important factor is to ensure that the entire photovoltaic installation has unrestricted access to sunlight. The exact choice of location is flexible, but most investors opt for mounting the panels on the roof. They can be mounted using stands or specially prepared structures. However, it is not recommended to install them directly on the ground, as it does not yield the expected results.
Typically, the most efficient and commonly chosen solution is to install the photovoltaic system on a roof with a 35-degree slope. It is also recommended to have the panels installed on the south side of the building's roof. Using such an arrangement usually guarantees that a 1 kWp panel will generate approximately 1000 kWh of energy annually.
Definitely yes! Solar energy for home becomes an even better solution when we consider the rising electricity prices. The average cost of a typical photovoltaic installation is around 30,000 Polish zlotys. However, it's worth considering the possibility of benefiting from EU subsidies for solar installations. Ultimately, these subsidies can significantly reduce the cost incurred by the investor. According to calculations made by the Tauron company, solar energy can save up to 2438 Polish zlotys per year.

Photovoltaic panels are becoming an increasingly popular choice among Polish investors. They offer many benefits, but despite that, many people still hesitate. Is photovoltaics worth it? And if so, how to choose the most efficient one? We have prepared a compendium of knowledge that should dispel any doubts regarding the operation of a photovoltaic installation.
Photovoltaics is not chosen only by people who care about ecology. It is indeed a great way to take care of our planet and reduce the emission of harmful carbon dioxide, but a significant advantage of this choice is also the savings that photovoltaic panels bring. However, does it apply to everyone? Is photovoltaics worth it for everyone? We have analyzed this.
In simple terms, photovoltaics for a single-family home is the process of obtaining electrical energy using sunlight. The cells inside the panel collect the current, which passes through the inverter and is then delivered to specific devices in the home. The construction itself can be expensive, but the electricity obtained from sunlight is free, so over time, the investment cost can be recouped. Moreover, a well-selected photovoltaic installation can provide full electricity demand for a single-family home.
How to Choose Good Photovoltaic Panels?
There are two main types of panels available on the market for such installations: polycrystalline and monocrystalline panels. They differ slightly, but as photovoltaic experts say, the type of panels is not as important as the brand's quality. It is not worth opting for the cheapest photovoltaic panels because their effective lifespan may not meet the basic requirements. Photovoltaics for a single-family home should work flawlessly for at least 25 years.
Furthermore, it is very important to ensure that the photovoltaic installation is tailored to the home's power needs. The exact demand for electrical energy for each home needs to be calculated precisely. Each home may have completely different results, and it is difficult to estimate a universal panel power for use. If you are interested in photovoltaics for a single-family home, it will be necessary to consult individually with an installation company that will perform the necessary calculations.
It is also worth knowing that whether photovoltaics are profitable for a particular home depends on the placement of the panels. The installer conducting the analysis will take into account the height and orientation of the roof, and the inclination angle is also essential. Some people also choose to place photovoltaics for a single-family home on a bracket instead of on the roof. Both solutions are valid and can work great, but before making a decision, it's worth discussing with the installer which option will be more cost-effective for you.
Photovoltaics has been known for over sixty years, but only now has it become so accessible to investors. Continuous work on its efficiency and profitability has made it a very advantageous solution today. The popularity of this solution means that it is no longer a premium product, and average families, not just photovoltaic farm owners, can opt for it. Many people wonder if photovoltaics is worth it - we can confidently answer yes. Why?
First of all, it's worth considering the rising prices of electricity in Poland. Over the last five years, the price of electricity has visibly increased, and all announcements and forecasts clearly indicate that costs will be even higher. For this reason, it's worth considering obtaining energy from other sources, such as residential photovoltaics. The larger the demand for electricity a building generates, the more cost-effective it is to install solar panels.
A home with a photovoltaic installation is more valuable. Solar panels can simply be treated as an investment. Their long-term efficiency makes a property with panels much more valuable and attractive on the market.
Another important issue is energy savings. Residential photovoltaics provide a constant power supply regardless of weather conditions, time of day, or year. How does it work? Solar panels allow excess generated energy to be stored and used later. As a result, the annual electricity costs for a single-family home are about 100 Polish zlotys.
However, there are situations where photovoltaics will not be a good solution. The installation will not be cost-effective when the house is heavily shaded. In such cases, sunlight won't be able to reach the solar panel. It is also not advisable to install solar panels on a roof in poor condition - it's better to renovate the roof first and then proceed with the panel installation.
When reading about whether photovoltaics are cost-effective, two main opinions can be found. The first is that solar installations are expensive, while the second suggests that the investment always pays off. How much truth is there in this?
Depending on the number and power of photovoltaic panels you purchase, the cost of the investment can vary significantly. The price of an installation typically ranges from 20,000 to 40,000 Polish zlotys per house, not including installation costs. The payback period for the investment also depends on the previous electricity costs for the home. The payback time can vary for each investment, but the typical payback period is usually between 9-13 years. It's worth noting that during this time, there will be no need to pay for electricity, which will continue to increase in price. The exact answer as to whether photovoltaics are cost-effective for your home can be provided by an installer. They will analyze your home's location, access to sunlight, and energy needs. After making the calculations, you can decide whether you need photovoltaics for your home.

Renewable energy sources are becoming increasingly popular among individual investors. This is directly related to growing environmental awareness, as well as unpredictable electricity prices. Many people take very seriously the obligation to leave future generations a planet suitable for living and functioning similar to ours. Undoubtedly, this attitude is commendable. As a result, there is an increasing number of photovoltaic installations on the roofs of Polish homes and in their immediate vicinity. Thanks to them, households generate electricity for their own use, significantly reducing home electricity bills.
Photovoltaics (from the English term "PhotoVoltaic," abbreviated as PV) is, in simple terms, a technology that converts solar radiation into electricity. Photovoltaic installations consist of photovoltaic panels, also known as modules. Such systems most commonly operate in an on-grid system, which means they are connected to the power grid. In cases where such a connection is not possible, we refer to it as an off-grid system. According to Polish law, when deciding to use our own photovoltaic installation, we become end consumers, or "prosumers," who generate electric energy for our own needs.
To put it simply, solar panels are built with photovoltaic cells, which are exposed to sunlight. Sunlit cells generate direct current (DC). However, to power electrical devices used in households, it is necessary to convert this into alternating current (AC). This conversion takes place in a device called an inverter. Currently, most photovoltaic panels installed on roofs have a height of 1.7 meters, a width of 1 meter, and can accommodate 60 photovoltaic cells.
The benefits of installing a PV system should be considered in terms of years, not months, because a well-designed and properly executed system is characterized by durability of up to 25 years. During this time, the decrease in module power should not exceed 20%.
the assumed power of the installation,
the construction, durability, and roof slope degree on which the photovoltaic installation is planned to be mounted,
the type of inverter,
the type of used accessories, such as mounting structures or cables,
whether the panels will be mounted on the roof (cheaper) or on the ground (more expensive),
whether the installation project and its assembly are included in the equipment purchase price,
service costs,
the amount of insurance for the installation.
The power of a photovoltaic installation can only be estimated approximately on one's own. Customers use calculators available online for this purpose. Accurate measurements are most often conducted by a company that specializes in designing and installing photovoltaic cells.
Such measurements take into account the following variables:
the region in which the PV installation will be mounted,
the level of insolation,
the roof or ground exposure intended for PV installation in relation to the cardinal points,
the tilt angle of the panels,
the coefficient of produced electrical energy, which results from the assumed inverter efficiency and the efficiency of the photovoltaic panels, as well as possible losses in the cabling.
Environmental Protection
Photovoltaics allows for obtaining emission-free energy from a renewable source, which, in practice, means an inexhaustible one. In this process, nothing is burned, so we do not release any greenhouse gases or other harmful pollutants into the atmosphere.
Savings in the household budget
The appropriate power of a PV installation allows for reducing household electricity bills, even down to zero.
The produced energy can be used not only for home lighting.
The electricity obtained from photovoltaic panels can also be used for operating household appliances, heating domestic water, underfloor heating, charging electric vehicles, etc.
Independence from fluctuating electricity prices
When we generate even a part of the required electrical energy through our own PV installation, increasing energy prices affect us to a lesser extent (or not at all).
Excess electricity can be utilized later.
Connecting a microphotovoltaic installation to the power grid allows for temporarily transferring any excess electricity produced and retrieving it when needed, for example, during the evening or in the winter season when days are shorter. In this situation, the power grid serves as a kind of electricity storage for us.
On-grid installations allow us to avoid the consequences of power outages.
In case of a power outage from the grid, we can still obtain electricity from our home photovoltaic installation since an on-grid system uses its own energy storage.
For the installation with a maximum power of 50 kWp, we do not need a permit.
In the case when we are both the producer and consumer of energy, and consequently, we use it exclusively for our own needs and do not profit from it, we do not need a permit. In this case, all the formalities applicable to us are closed in the notification of the installation to the appropriate energy company.
Possibility of obtaining subsidies from the "My Electricity" program
The program provides financial support for building home photovoltaic installations for individuals up to the amount of 5,000 PLN. The condition is that the power of the installation does not exceed 10 kWp. In 2020, about 220,000 prosumers benefited from this program. Such a huge success has prompted the government to work on the next edition of the program for the year 2021. Current information can be found on the website mojprad.gov.pl.
Possibility of obtaining subsidies from the "Clean Air" program
This program is dedicated to owners of single-family homes and separate residential units in single-family buildings with a separate land and mortgage register. The subsidy covers the replacement of solid fuel heating sources with ecological heating sources and necessary thermal modernization of buildings. The basic subsidy amount is up to 30,000 PLN. Detailed information about the program can be obtained at https://czystepowietrze.gov.pl/.
When considering the use of subsidy programs for a home photovoltaic installation, it is important to remember that THEY CANNOT BE COMBINED.
Tax benefits resulting from owning a private PV installation
Investment allowance for farmers
It amounts to 25% of investment costs and is deducted from the due agricultural tax. In the case when the installation cost exceeds the annual agricultural tax fee, the deduction can be carried out annually for up to 15 years.
Thermal modernization allowance
For owners and co-owners of older single-family homes undergoing thermal modernization. The value of the installation up to a total of 53,000 PLN gross (including installation) is deducted from the basis of the due income tax. The allowance is available to all PIT taxpayers regardless of the tax scale they use (17%, 32%, linear tax, and lump-sum on recorded income). Importantly, this allowance can be used by individuals who have benefited from the subsidy available in the aforementioned "My Electricity" program. However, the amount of the tax deduction is reduced in this case by the amount of the received subsidy.
