What are the Benefits of Advanced Heating Systems?

Energy-efficient heating systems offer a number of benefits, some of which are described below.

Energy savings are a key consideration when choosing an energy efficient heating system. Lower energy consumption means that we need to buy less energy and, as a result, our monthly energy bills will be lower.

Modern heating systems are more flexible and convenient. For example, they are easy to control, so you can easily set the desired temperature in different rooms. This increases comfort and helps to meet individual needs.

Heating systems based on alternative energy sources offer an environmentally friendly solution. Renewable energy sources, such as solar or geothermal, not only reduce emissions during operation, but are also more sustainable in the long term.

What are the benefits of modern heating systems?

The total monthly bill depends on the amount of energy used. As a rule, the less energy you use, the less you pay. Here are some of the benefits of modern heating systems:

  1. Efficiency: Modern heating systems use energy efficiently, resulting in lower running costs.
  2. Comfort: These systems are usually easy to adjust and remote control, so you can easily adapt them to your current heating needs.
  3. Environmentally friendly: Many modern heating systems offer environmentally friendly solutions, minimising emissions and contributing to sustainability.
  4. Long-term savings: Although installation costs may be higher, in the long run, modern heating systems can reduce heating bills and pay for themselves.

What are the most common heating systems?

  1. Fireplace and stove: These are traditional heating solutions, but are usually used as supplementary heating.
  2. Gas boiler, gas boiler, condensing boiler: These systems are often used, especially for floor, wall or ceiling heating.
  3. Gas convector heating: It is convenient as the temperature in each room can be controlled independently, but more units are needed for larger properties.
  4. Solid and mixed fuel boilers: These boilers can run on wood, coal or other fuels and are easy to maintain, but fuel storage needs to be taken care of.

What modern (alternative) heating options are available?

  1. Infrared heating: It converts electricity into infrared heat waves and is easy to install.
  2. Heat pump: It harnesses energy from the sun, water or soil and is an energy-efficient solution.
  3. Geothermal energy: It uses pipes drilled into the ground to extract the heat energy stored in the ground, an environmentally friendly system that pays for itself in the long term.
  4. Solar heating: Solar panels can cover your entire energy needs, but they come with higher installation costs.

What aspects should be considered when designing heating systems?

  • Objective: First, determine the purpose of the new heating system (main heating, auxiliary heating, etc.).
  • Financial framework: It is important to take into account the available budget, as modern technologies may involve higher investment costs.
  • Building features: The orientation, size, ceiling height and thermal insulation of the building also affect the efficiency of the heating system chosen.
  • Environmental factors: The environmental factors of the area can also affect the efficiency of the system (e.g. amount of sunshine, temperature, etc.).

Modern heating systems often have a longer lifetime and require less maintenance. This can save money in the long run through reduced maintenance costs.

Energy efficient heating systems can contribute to increasing the value of a property and make it more attractive to potential buyers or tenants.

Finally, energy efficient heating systems can further reduce costs through often available subsidies and incentives, making the investment even more attractive.

These considerations can be important when choosing a new heating system. It is worth considering carefully the most appropriate heating solution according to your individual needs and the options available.

Before choosing a heating system, it is worth considering these aspects carefully and, if possible, seeking professional help to find the ideal solution for you. SolarKit's experts can help you navigate the different options and find the best heating system for your needs.

Solar System Expansion - Is it possible?

The article is about how to expand solar systems, with a focus on inverters, solar panels and optimisers. Solar systems ideally cover average consumption, but consumption may increase after the system has been installed, for example due to the use of air conditioning or an electric car.

If such changes are anticipated when designing the system, it may be worth installing a larger inverter to allow for easy expansion later, or even installing a larger system from the outset. However, it is important to note that it is not worth installing too large a system, as the electricity supplier will buy the electricity they buy at a low price.

The article stresses that when expanding a solar PV system, a number of technical aspects need to be taken into account to ensure that the system works properly. The advice of experts is recommended for the expansion.

It highlights three main aspects of expansion: the inverter, the free roof space and the type of solar panels.

The inverter plays an important role in the expansion and to ensure that the inverter can handle the added power. Inverters are usually oversized, but the phase number of the inverter must also be taken into account.

Optimisers are also important, as they help to ensure that the performance of solar panels is not reduced if one of them is exposed to shading or dirt.

The compatibility of solar panels is also highlighted and it is recommended that the technical characteristics are similar, even if different brands of solar panels are used for the expansion. For old systems, it is important to involve optimisers and specialists in the design of the expansion.

Finally, the article mentions the development of solar cells, in particular the renaissance of monocrystalline solar cells, which are more efficient and cheaper to produce than earlier types. However, there are some technical difficulties in combining different types of solar cells.

The article encourages readers to contact experts if they want to upgrade their solar system to make the best decision for the efficiency and yield of their system.

Solar PV system parts (and construction)

Structure of the solar system

When deciding to install solar panels, it is important to understand the components of such a system. The properties and quality of the system's components are crucial to its efficiency and will affect the time it takes to get a return on our investment.

What exactly is a solar panel?

A solar cell is a photovoltaic cell that directly converts the sun's radiant energy into electrical energy. This electrical energy can either be fed into the grid or stored in batteries.

However, the solar panel alone is not enough, as it only produces direct current (DC). We need an additional battery to convert this direct current (DC) into alternating current (AC) to use it in our home devices.

It is important to note that a solar panel and a solar collector are two different things. A solar panel produces electricity, while a solar collector produces hot water.

The efficiency of solar panels has increased significantly over the years. The first solar cells in the 1950s had an efficiency of only 1-4%, while the best commercially available types today have an efficiency of 20-23%. In addition, prices have fallen significantly over the years, making solar PV systems an economical investment that can pay for itself in a short time.

A solar system offers a cost-effective option for environmentally friendly and energy efficient homes. These systems work well in combination with, for example, a heat pump, which allows heating to be provided with environmentally friendly and renewable energy, and even generates the electricity needed from the solar panels. It is also possible to charge an electric car, making driving more energy efficient.

Parts of the solar system:

  1. Main types of solar panels: The two most common types are monocrystalline and polycrystalline solar cells. They have different structures, but both produce electricity. Monocrystalline solar cells generally have a higher efficiency (20-22%), while polycrystalline solar cells (19-22%) perform better in scattered light and cloudy weather. Both types operate efficiently in Hungary.
  2. Inverter: Solar panels generate direct current (DC), while our home devices and the grid use alternating current (AC). The inverter's job is to convert DC power into AC power, and thus forms the heart of the system. Inverters have different power outputs and it is important to choose the right size to ensure system efficiency.
  3. Energy storage (batteries): Batteries allow energy storage, so the energy generated does not need to be fed into the grid immediately, but can be stored and used later. This can be particularly useful in areas where mains electricity is not available or where power cuts are frequent. The batteries can be connected to the system so that they are charged directly by the solar panels.
  4. Smart metering: Smart meters help you monitor energy production and consumption in your home. This allows you to use energy more efficiently and optimise your system.
  5. Optimisation of solar panels: Performance optimisers allow each solar panel to be monitored and optimised separately. This is particularly useful for pitched roofs or shading, where solar panels have different outputs.
  6. Support structure: The mounting bracket ensures that the solar panels are securely and safely fixed to the roof or other surface. The material of the mounting bracket is important for the long life of the system and should be rustproof.
  7. Cables and installation materials: Cables and electrical installation materials are essential for the operation and safety of the system. Their quality and durability are key to long-term reliability.
  8. Ad-vesz meter: In the case of balance billing, a special meter is installed that can measure the energy consumption from the grid and the energy fed back into it. This is essential for the energy distributor to measure the energy we produce and use.
  9. Licensing of electricity suppliers: Before installing a solar system, you also need to obtain a permit from the electricity company. This ensures that the system will work in accordance with local rules and regulations.

Designing and installing a solar PV system is a complex process that requires quality components and professional installation. Careful planning and selection can help make your solar system a long-term return on investment.

Cleaning solar panels: how to?

Cleaning solar panels is an important topic and understanding when and how to clean them is essential. Here's the formulation again:

Cleaning solar panels: how to?

Cleaning solar panels is a sensitive issue and if not done properly, they can cause damage. In this article, we have put together a list of when and how to clean solar panels.

When should solar panels be cleaned?

In general, solar PV systems do not require regular cleaning, as the rain cleans them on its own, and even in periods of no rain they do not get dirty enough to be worth cleaning.

A major study at the University of San Diego tested the efficiency of solar panels during 145 rain-free days. The results showed that even without rain, there was only a loss of efficiency of 7.4%, a relatively small cost increase for an average residential system. The situation is even better in Hungary, where there are no long periods without rain.

Efficiency losses can be noticeable in larger industrial systems, especially during long periods without rain. In such cases, it may be worth considering regular solar panel cleaning services or the purchase of appropriate cleaning equipment.

For residential solar PV systems, cleaning is generally not necessary, as the cost of cleaning can exceed the production loss. However, there are exceptions.

Stubborn dirt, accumulated leaves or large amounts of dirt can cause inefficiency in the long term. In such cases, you may want to consider cleaning your solar panels, but it is always worth checking first to make sure that it is really necessary.

How NOT to clean solar PV systems?

It is important to understand that poor cleaning methods can damage solar panels. Here are some things to avoid:

  1. Do not clean during the day when solar panels are heating up, as pouring cold or room temperature water on them can cause cracks.
  2. Do not use a pressure washer or steam cleaner as these can damage the surface of the solar panels.
  3. Avoid caustic cleaning products as they can cause malfunctions or electric shock.
  4. Do not attempt to dry clean, as dry cleaning can cause scratches that can lead to a loss of efficiency.
  5. Do not use hard water, as minerals can deposit on the surface of solar panels.
  6. Never step on a solar panel system because it can damage the panels and it can be dangerous to stay on the roof.

How can solar panels be properly cleaned?

The safest choice is to hire professionals to clean your solar panels. This is especially true for larger systems where efficiency losses can be significant.

If you do want to clean it yourself, it is important to do your research. The solar panel manufacturer usually provides specific cleaning advice that you should follow. You will need appropriate cleaning tools, such as those designed for solar panels.

It is important to use only clean, distilled water and always wear appropriate protective equipment, especially when on roofs. Cleaning should be done before dark or dawn to avoid heating up the solar panels.

Soak the solar panels in distilled water (do not use a pressure washer), then gently wipe with a special or soft sponge. Remove stubborn dirt with a sponge and a non-abrasive cleaner, then wash the panels again.

Why is solar worthwhile for businesses?

Why should businesses invest in solar PV and heat pump systems?

  1. Lower operating costs: By using solar panels and heat pumps, you can reduce your fixed operating costs.
  2. Long-term energy management: The investment will allow it to become independent from rising energy prices, which is key to price stability.
  3. Fast payback and long life: Solar panels come with a 25-year performance guarantee, so they provide an excellent long-term return on investment.
  4. An environmentally conscious choice: By using renewable energy sources, you can reduce your emissions and help protect the environment.
  5. Land use: You can use the roof or ground area of your property to install solar panels, optimising the available space.

Important: The installation of solar systems always requires an individual assessment and a personalised quotation.

Our services cover the entire investment process, including project management, use of grant funding, connection planning, permitting and turnkey construction.

Let's look at an example!

Let's assume that your average monthly electricity bill is 225 000 HUF, which means an annual consumption of 2 700 000 HUF of electricity. A 50 kW solar PV system is needed to cover the total annual energy demand, at a cost of nearly HUF 15 million + VAT. So the payback period would be about 5.5 years: 15 million HUF / 2 700 000 HUF = 5.5 years. The payback period can be further reduced by using subsidies.

Once installed, the system is virtually maintenance-free and the manufacturer offers a 25-year performance guarantee on the solar panels.

Settlement system above 50 kW

Options for the Construction of a Solar Carport

Options for the Construction of a Solar Carport

First of all, a solar carport, also known as a solar carport, offers benefits that may seem too good to be true.

  1. It provides weather protection and coverage for our cars.
  2. The PV modules are optimally oriented and the number of panels can be easily scaled, which increases energy production.
  3. It is possible to charge an electric car at the entrance, which uses renewable energy for our mobility and reduces carbon emissions.
  4. Redundant parking areas can also be covered with solar panels, improving the use of space.

However, it is no coincidence that many solar companies are reluctant to have a solar carport professionally built. The success of a project requires a unique survey, design and experienced professionals.

Solar carports are always made with personalised consultation and individual design, as they can be implemented in many different ways. This gives them an advantage but also makes them a challenge.

Some important questions to ask when installing a solar carport:

  1. How many vehicles do we want to cover with solar panels?
    • For family houses, it is easier to use a fixed structure, while for corporate clients we use a modular solution that fits the needs.
  2. What is the ideal layout?
    • The PV modules can be arranged in a V-shape to allow cars to park opposite each other and increase energy production with optimal orientation.
  3. What material and how do we build the structure?
    • The structure can be made of metal or wood, depending on the customer's preference and budget.
  4. How do we cover the carport?
    • The carport can be covered by the solar panels themselves, but it is important to pay attention to aesthetics and waterproofing. Another option could be to use sheet or shingle roofing.

Solar car parks offer a number of benefits, combining renewable energy production and car protection. It can also be a financially valuable investment in the long term.

Corporate solar systems can be beneficial for the environment and cost savings. Turn to our experts, who have half a decade of experience and more than 3,500 solar PV and heat pump systems installed.

An innovation in industrial solar farms is the use of rotating support structures that allow sun-tracking, which increases energy production. These mounts are used in collaboration with proven and quality manufacturers to build solar carports.

Finally, we can mention the possibility of solar terraces and pergolas, which can be built using a similar logic to carports and can provide a stylish and useful solution for the garden.

Overall, installing a solar carport is a decision that combines sustainability with practicality, but it requires careful planning and expert contractors.
