Autoconsumption in photovoltaics - what is it and what does it depend on? Autoconsumption in photovoltaics is a term that refers to the on-site consumption of electricity generated by a photovoltaic system, i.e. directly by a household, business or other entity that has a photovoltaic installation. Autoconsumption refers to the use of electricity produced by photovoltaic panels to power equipment and systems in...
How do weather conditions affect the efficiency of photovoltaic installations? Nowadays, solar energy has become one of the most popular and environmentally friendly energy sources. With the growing interest in photovoltaic installations, it is crucial to understand how to optimise their performance under different weather conditions. Weather and climate have a significant impact on the efficiency of solar panels, so it is useful to know strategies,...
Why is the bivalent point of a heat pump so important? Heat pumps are a green and very popular solution for heating homes and public buildings, providing energy efficiency and promoting sustainability. One of the key aspects to consider when selecting and designing a heat pump system is the so-called bivalent point. In the following article, we will try to explain,...
Low-temperature and high-temperature heating Heat pumps are gaining popularity as environmentally friendly and cost-effective solutions for heating homes and buildings. Although low-temperature and high-temperature heat pumps share the same operating principle, there are important differences in some respects. When deciding to install such a system, it is useful to understand the differences between a low-temperature and a high-temperature heat pump in order to choose the model best suited to...
Photovoltaics on buildings in Poland will be mandatory Mandatory photovoltaics on all buildings? On 12 March 2024, the European Parliament voted on a directive on the energy efficiency of buildings, the so-called Buildings Directive. This means that all new buildings in the EU must be zero-emission. The EU is thus accelerating the energy modernisation of residential and non-residential buildings. Mandatory energy production from the sun The new law...
How much energy storage is enough? Energy storage makes it possible to become independent of the grid supply. Choosing the right energy storage is crucial to the efficient and economical operation of a photovoltaic system. Energy storage allows you to store excess electricity produced by photovoltaic panels so that it can be used during periods of less sunshine or at night. For how long will a domestic...
Energy audit - what is it? An energy audit of a building is the first step towards reducing energy intensity. It is a technical and economic expert opinion on the energy use of the building under study. The result of the audit is not only a detailed report describing the current energy consumption, but also a set of recommendations to help improve the energy efficiency of the building. Such an audit may concern simple modifications as well as ...
Photovoltaic guarantee - how does it work? Purchasing a photovoltaic installation is an investment with long-term benefits. An undeniable advantage of photovoltaic panels is that they have a low failure rate. They are characterised by the absence of moving parts, which minimises the risk of mechanical failure. Nevertheless, warranties for photovoltaic installations are an important element to ensure long-term comfort and safety of use. In the case of photovoltaics, there are...
How to detect a faulty photovoltaic panel? Nowadays, solar energy is becoming an increasingly popular source of energy, thanks to its environmental friendliness and cost-effectiveness. However, like any technology, photovoltaic installations can also encounter technical problems. A faulty PV panel can significantly reduce the efficiency of the entire system, so it is important to locate and repair it quickly. In this blog post, we outline some...
Is a storm dangerous for photovoltaics? A thunderstorm is one of the most dangerous atmospheric phenomena. Every year, lightning causes a lot of damage with heavy rain, gusty winds and lightning. Should owners of a photovoltaic installation be afraid of a thunderstorm? What risks does a lightning storm have for a photovoltaic installation? Check! Does photovoltaics attract lightning? It is a myth to believe that...
How do you find out how much electricity your photovoltaic system has produced? Have you ever wondered how much energy your photovoltaic installation has produced? Monitoring the efficiency of your installation is key to understanding how much solar energy is converted into electricity. In this article, we'll discuss some methods to help you track the performance of your photovoltaic system. Energy given up and energy taken in - what you need to know Understanding the difference...
Subsidies for domestic wind farms in 2024? The National Fund for Environmental Protection and Water Management (NFOŚiGW) has prepared a project to subsidise backyard wind power plants. Those interested in investing in this type of solution will be entitled to financial support and, in addition, under the programme, they can count on assistance in financing the purchase of energy storage. What does the programme consist of? According to information published by the National Fund for Environmental Protection and...
