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...
