What is the COP in heat pumps? COP stands for coefficient of thermal performance, which is a key parameter in assessing the efficiency of heat pumps. To understand what the COP is and what it means, it is useful to look at its definition and practical applications. Definition of COP The COP (Coefficient of Performance) is the ratio between the amount of heat delivered by a heat pump...
How to choose a photovoltaic contractor? Checklist. Choosing the right photovoltaic contractor is crucial to the effective and trouble-free operation of the system. The right choice will ensure that the installation is properly sized and installed, providing greater benefits and safety for residents. It is therefore worth properly vetting the companies on the market. What should you look for? Which offer should you choose? Take advantage of...
Solar collectors (solars) versus photovoltaic panels (modules) - what are the differences? Solar collectors and photovoltaic panels are apparently two similar systems that use solar energy. Many people confuse photovoltaic panels and solar collectors, mainly because of their similar appearance. Both systems can be mounted on roofs and on the ground. What they have in common...
Any builder with plans to build or modernise a house faces an important decision regarding what type of heating to choose for their home. The factors that ultimately influence the choice are mainly the costs resulting from the purchase of the heating device and the charges associated with its operation in the future. In addition, the impact of the heating appliance on the climate is important. In relation to ...
Size of photovoltaic panels - what does it depend on? When deciding on the installation of a photovoltaic system, in addition to the power, the size and weight of the photovoltaic panels should also be taken into account. At the same time, it is important to bear in mind that roof constructions vary, which affects the possibility of using specific mounting solutions. What do the dimensions of photovoltaic panels depend on and what are they? What is the weight of the panels...
The lifespan of a heat pump is a key topic for those who decide to invest in this source of heating for a building. Is the investment long-term? How many years can a heat pump operate without losing performance? What factors can reduce the service life? These and other questions are answered in the following article! The service life of a heat pump depends on many...
kWp - what does the abbreviation stand for? kWp is an abbreviation for 'kilo Watt peak', which translated into Polish means 'kilo Watt maximum'. It is a unit of power that refers to the maximum production capacity of a photovoltaic (PV) module or the entire PV installation under certain conditions, called Standard Test Conditions (STC). STC conditions,...
HEMS (Home Energy Management System) is a system for managing energy in the home. Its primary objective is to optimise energy consumption in real time through monitoring, control and automation. HEMS integrates different energy systems - photovoltaic installation, energy storage and home appliances. It can help save electricity and increase the comfort of living for household members. The HEMS system...
What is a bypass diode in a photovoltaic panel? What is it used for? A bypass diode, often also referred to as a protection diode or bypass diode, is an important component in the design of photovoltaic panels. It serves to protect the photovoltaic cells and ensures better module performance under partial shading conditions. Principle of the bypass diode Under normal sunlight and no shading, current flows through the...
Until now, in order to build a photovoltaic installation with a capacity of more than 50 kWp, the developer had to obtain a building permit. The procedure was often lengthy and expensive, which increased the costs from the investment. On 17 August 2023, an amendment to the Renewable Energy Sources Act came into force, which introduces significant changes. From now on, installations with a capacity of up to 150...
Most photovoltaic panels are made from silicon wafers. Silicon is a very valuable resource for our planet as it is available in abundance. The manufacturing process of photovoltaic cells is described in detail in a previous article. How are photovoltaic panels made? Solar panels are made from six main components. They are assembled in advanced manufacturing facilities with extreme precision,...
