Problem - Energy dependence and its consequences

In recent years, we have seen a drastic increase in the cost of electricity. Bills that used to be a small part of the household budget can now be a headache. I remember talking to Mr. Marek, the owner of a single-family house near Warsaw, who showed me his electricity bills from three years ago and the current one. “The difference is shocking,” he admitted. “It's like every month someone takes an extra 300 zloty from my wallet.”

And it's not just about the costs. The stability of energy supply, which we once took for granted, is becoming increasingly uncertain. Local failures, planned outages related to grid upgrades and even systemic energy crises all make traditional energy sources less reliable than they used to be.

“When we were without electricity for the third time in a month, I decided to take matters into my own hands,” Mr. Tomasz, an engineer from a town near Krakow, told me. “Working remotely with uncertain power is like driving a car that can run out of fuel at any moment.”

Many homeowners are turning to rooftop photovoltaics as a solution to these problems. But here, too, there are limitations. Not every roof has an adequate surface, slope or orientation relative to the sides of the world. Some roofs are shaded by trees or neighboring buildings. Other owners are worried about the tightness of the roof after installing photovoltaic panels or simply do not want to interfere with the existing structure.

Moreover, many people do not make full use of the space that could be used for energy production. A parking space in front of the house or next to the garage is often a dozen square meters of space exposed to sunlight - an area that normally does not do any additional work. Imagine that the same space could not only protect your car from rain, snow and hail, but at the same time produce electricity for your home.

As noted by energy expert Dr. Anna Kowalska: “One of the biggest challenges of energy transformation is convincing people that every piece of space can have dual functionality. A parking space is a prime example — it protects the car and can generate energy at the same time.”

This untapped space is a lost potential — a potential that could lead to greater energy independence, lower bills and better preparation for a future in which electricity plays an increasing role in our daily lives.

Solution - Photovoltaic carport as a home power plant

The photovoltaic carport is the answer to the need to combine practical vehicle protection with electricity generation. Unlike traditional canopies, which perform only one function, the carport with solar panels is a practical example of how modern technologies allow multifunctional use of space.

The design of a flat-roofed photovoltaic carport may seem counterintuitive to people who associate solar panels with sloped surfaces. “When I offered my client a carport with a flat roof, his first reaction was disbelief,” recalls Paweł, an installer of photovoltaic systems with 10 years of experience. “He was convinced that the panels had to be tilted at 30-40 degrees to work effectively.”

However, the reality is different. Modern photovoltaic panels mounted on flat roofs of Electrotile carports achieve surprisingly good performance. Although theoretically the optimal slope for our latitude is about 35 degrees, the difference in annual energy production between an optimally inclined panel and a flat mounted panel is often only 10-15%.

This small loss is offset by a number of benefits. The flat roof allows you to make the most of the available space, which translates into a greater number of panels and a higher total installation power. In addition, the structure is less exposed to damage from strong winds, and its installation is simpler and faster.

“We installed a photovoltaic carport with an area of 24 m² and a capacity of 5.04 kWp,” says Małgorzata, owner of a house near Poznań. “Such an installation covers about 60% of our annual electricity demand.”

The integration of the carport into the home power system is simple and does not fundamentally differ from the connection of a classic photovoltaic installation. The direct current produced by the panels is converted into alternating current by an inverter and then goes to the home electrical network. Surplus energy can be discharged to the public grid or stored in a home energy storage.

Energy storage is another step towards full energy independence. A storage capacity of 10-15 kWh allows you to store surplus energy produced during the day and use it in the evening or on cloudy days. “It's like having your own energy bank,” explains Anna, a specialist in energy storage systems. “Instead of giving the surplus to the network, you accumulate it in your account and withdraw it whenever you need it.”

The photovoltaic carport can also be equipped with a charger for electric cars, which allows significant savings for owners of electric vehicles. “Charging an electric car with energy from your own photovoltaic panels is like having a gas station in your own yard,” says Krzysztof, who has been using such a solution for two years. “Charging costs have dropped to virtually zero in the summer months.”

Importantly, the photovoltaic carport can be expanded in the future by adding more modules or increasing the capacity of the energy storage. It is a solution that grows with the needs of the user and evolves with technology.

Benefits - The Path to Energy Independence

Investing in a photovoltaic carport is not only a step towards an ecological lifestyle, but above all concrete financial savings. A 5 kWp plant can produce about 5000 kWh of electricity per year. With current energy prices of PLN 0.70-0.90 per kilowatt hour, this means savings of PLN 3500-4500 per year.

“For the first year, I carefully monitored the energy production from my carport,” shares his experience Piotr, owner of a single-family house in the vicinity of Wroclaw. “In the best months, the installation covered more than 80% of our energy needs. In total, during the year we saved more than 4000 PLN on bills.”

Moreover, thanks to government support programs such as “My Power”, it is possible to obtain financing for a photovoltaic installation, which significantly shortens the payback period. An additional benefit is the possibility of deducting the investment from tax as part of the thermo-modernization allowance, which can bring additional savings of up to PLN 16,000.

But financial savings are only one side of the coin. At a time when we are increasingly experiencing power outages, a photovoltaic carport combined with an energy storage ensures energy security.

“During the last storm, when the entire area was without power for more than 12 hours, our basic appliances — refrigerator, lighting, internet — worked without interruption,” says Maria, who invested in a carport with an energy storage facility. “It gives you a sense of peace that can't be translated into money.”

Energy independence also has a psychological dimension — the awareness that energy production takes place on site, under the control of the owner, and not in a remote power plant, to which hundreds of kilometers of transmission lines are exposed to failure.

It is also worth mentioning the increase in the value of real estate. As the environmental awareness of society grows and energy costs increase, houses equipped with renewable energy production systems are becoming more attractive in the real estate market. According to a study conducted by the National Energy Conservation Agency, houses with photovoltaic installations sell on average 5-8% more expensive than comparable properties without such installations.

“When we bought our house, one of the key factors for us was the presence of a photovoltaic installation,” admits Adam, who recently moved to a new home. “We were willing to pay more, knowing that our energy bills would be significantly lower.”

The photovoltaic carport is also a look into the future — preparing for the coming era of electrification. As electric cars become more accessible and heat pumps displace traditional heating systems, the demand for electricity in households will increase. Having your own energy source becomes not only a matter of savings, but also a necessity.

“We installed a photovoltaic carport with the future in mind,” says Tomasz, who plans to buy an electric car. “I knew that once I decided to become an electrician, my electricity demand would double. Thanks to the carport, I will be able to charge the car at home using my own energy.”

The photovoltaic carport is not only a roof for the car, but a real step towards energy independence — independence that translates into financial savings, energy security and preparation for the challenges of the future.
